Short answer: a push mower fits a 6×4 shed with a door opening of at least 32 inches, a riding mower needs an 8×10 at minimum with a 50-inch-plus opening, and a zero-turn with a wide deck needs a 10×12. Add two to three feet of clearance on every side so you can still walk around the machine once it is parked.
We have been putting lawn mowers into sheds for years, mostly into whatever spare corner existed, and the number one complaint we hear is the same every time: the mower fits the floor area on the spec sheet but will not clear the door, or the shed is so tight that nothing else fits beside it. That is why this roundup leads with door opening width in inches rather than square footage.
The best storage sheds for lawn mowers in 2026 fall into three camps. Resin units such as the Suncast 54 and the Keter Manor need no painting and will not rot. Galvanized steel sheds like the Gizoon 6×4 and the Aoxun cost less and hold more, but need a base. Walk-in resin buildings such as the Suncast Tremont 8×10 are the only real answer for a riding mower plus a workbench.
We compared twelve sheds, pulled the door and interior dimensions for each, and checked where the floor kit is included and where it is not. Nothing on this list is a guess about fit; every dimension below comes from the manufacturer spec or the listing. If you are still choosing a mower, our guides to the best lawn mowers and the best cordless lawn mowers cover the machines these sheds have to swallow.

1. Suncast 54 Cu Ft Vertical Resin Shed – Best Overall for a Push Mower and Hand Tools
Suncast 54 Cu Ft Medium Vertical Storage Shed, Stoney, Made in USA
54 cu ft vertical body
41 inch wide by 32.5 inch deep
46.25 inch door opening
Shelf notches for three shelves
Floor base included
Pros
- Tall narrow shape fits a push mower plus long-handled tools
- Built-in shelf notches hold up to three shelves
- Multi-wall resin and included floor base
- Padlock-ready handles with a resin latch
Cons
- Two people needed for assembly especially the roof
- Corners do not seal tightly so it is not fully weatherproof
- Doors only swing properly on a level base
This is the shed we keep coming back to. The Suncast 54 packs 54 cubic feet into a footprint of just 41 by 32.5 inches, which is narrower than a door and shallower than most patio tables. That shape is the whole point: it goes where a 6×4 will not fit and still swallows a push mower with its handles folded, plus rakes and a shovel stood up along the wall.
The 46.25-inch double door opening is far wider than the 28 to 32 inch openings on most push-mower sheds, which means you are not angling the mower in at an awkward angle. It rated 4.4 across about 1700 reviews, and 71 percent of those ratings are five stars, which is the strongest distribution in this group. Suncast also backs it with a ten-year limited warranty, longer than anything else on the list.
Built-in notches in the side panels accept up to three shelves, so it converts from mower parking to a proper tool shed without drilling. The wall material is multi-wall resin with an HDPE frame, and the floor base is part of the box, which removes one of the two most common add-on costs.
Where it falls short is sealing. The corners do not meet tightly, so in driving rain you can get a drip line where the panels join, and the doors bind unless the base is genuinely level. Assembly is a two-person job, most of it wrestling the roof panels into place.
Check the door width before you commit
Measure your mower at the widest point, which is usually the deck rather than the handlebar or the bag. A 21-inch push mower deck is roughly 22 inches across at the deck, but the handle and the discharge chute add to the silhouette, so measure the whole machine as you would push it through the door.
The Suncast 54 gives you a 46.25-inch opening and 54 cubic feet, which is comfortable for one mower and the long-handled tools that normally lean against a garage wall. If your plan involves two machines or a snow blower as well, this is the wrong footprint and you want the walk-in unit further down.
Know when to skip it
Skip this shed if you plan to store a riding mower or a zero-turn, because 41 inches of width is nowhere near enough. Also skip it if you live somewhere with sustained rain and no patience for a drip tray, or if you are building alone and cannot recruit a second pair of hands for the roof.
If you like the idea of a mower shed but want more general-purpose storage for bins and bikes, our best outdoor storage sheds guide covers larger metal and resin buildings in more detail.
2. Suncast Tremont 8×10 Resin Shed – Best Walk-In Space for a Riding Mower
Suncast 8×10 Ft. Outdoor Storage Shed – Large Resin Outdoor Shed with Floor Included, Lockable Double Doors & Skylights. 547 Cu Ft Tremont Garden Resin Sheds for Lawn Tools, Riding Mowers, & Bikes
547 cu ft of walk-in space
100.5 inch wide by 103 inch deep
Lockable double doors
Six skylights and vents
Floor base included
Pros
- 547 cu ft of walk-in space sized for riding mowers
- Six skylights and door windows for daylight
- Lockable double doors and included floor base
- Pre-cut labeled parts for minimal-tool setup
Cons
- Heaviest unit here at 384 pounds
- Top of the resin price range
- Water resistance is not the same as a sealed building
This is the only genuinely walk-in unit we tested, and that changes everything about how you use it. At 100.5 inches wide by 103 inches deep with a 122-inch peak, you drive the mower in, park it, and still have room to walk around it, hang a workbench on the back wall and reach a toolbox without moving the machine. That is the difference between a shed and a garage you can almost work in.
547 cubic feet is enough for a riding mower plus a snow blower, a wheelbarrow and stacked bins, all under one roof. The panels are steel-reinforced resin, which holds up to impact from a mower deck and will not rust, and the floor base is included. Six skylights plus windows in the doors mean you can work inside without a work light.
It rated 4.3 from roughly 1120 reviews, with 70 percent five stars, and the reviews reflect the trade-off honestly: people value the volume and the light, and they note the weight and the cost. It is 384 pounds of panels, so this needs several adults and a full weekend rather than an afternoon.
Do not expect a sealed building. Water resistance is good but it is resin, so a driving-rain shed with a mower that stays damp inside is a real scenario. Keep a dehumidifier or at least a desiccant block in there if you are in a wet climate.
Will your riding mower actually clear the door?
Before you commit, measure your mower across the deck at its widest point including the wheels, then add four inches of clearance. A typical 42 to 48-inch deck riding mower needs roughly 52 inches of opening, and a zero-turn with a 54 or 60-inch deck needs 64 inches or more. Measure the doorway, not the building width, because the building includes wall thickness and the door frame.
Also measure your mower with the steering wheel turned and the seat up if it folds, because that is how you will be maneuvering it in. If you have a mower plus attachments that come off, confirm the shed has enough wall length to set the deck on its edge against a side wall rather than blocking the door swing.
Know when to skip it
Skip this one if the build is a one-person job, because 384 pounds of panels does not go together alone. Skip it if you have a tight budget, since this sits at the top of the resin range, and skip it if you have a zero-turn with a 60-inch deck, where you really want a 10×12 or a 12×20 building rather than an 8×10.
It also needs a flat, level pad. On an uneven gravel bed the doors will not close properly and the floor will rock under a mower that weighs several hundred pounds.
3. Keter Manor 4×6 Resin Shed – Best Value for a Push Mower and Yard Gear
Keter Manor 4×6 Resin Outdoor Storage Shed Kit-Perfect to Store Patio Furniture, Garden Tools Bike Accessories, Beach Chairs and Lawn Mower, Grey & White
131.8 cu ft capacity
51.2 inch wide by 75.6 inch deep
51.2 inch door opening
Polypropylene resin with steel frame
5 year warranty
Pros
- Largest review base in the group at about 3900 ratings
- Polypropylene resin and steel that will not peel rot or rust
- Skylight plus window and venting for airflow
- Waterproof and UV protected exterior
Cons
- Corrugated plastic floor dents under heavy equipment
- Thin side panels can flex or bow
- Two-person build especially the roof
The Keter Manor 4×6 is the one we recommend most often, and the reason is the review volume. At roughly 3900 ratings it carries the largest verified feedback base of any shed here, which means the faults below are well documented rather than anecdotal. If a reviewer found an issue, hundreds of others have found the same one.
Dimensions are honest and consistent: 51.2 inches wide by 75.6 inches deep by 78 inches tall, with a matching 51.2-inch door opening and 74.8 inches of interior headroom. A push mower plus fertilizer, bags of seed and a couple of bikes fits comfortably, and the wide opening means you are not fighting the door every time.
The build is polypropylene resin with a steel frame, rated waterproof and UV protected, so it needs no painting and will not rot or rust. A skylight and a window plus vented airflow keep it from becoming a dark damp box. Keter supplies a five-year warranty against manufacturing defects, though that warranty does not cover acts of nature.
The floor is the weak point. It is corrugated plastic rather than a solid panel, and several owners report it denting or flexing under heavy equipment. If you plan to store anything heavy or store it directly on the floor, add a pressure-treated base or lay plywood over the top.
What fits and what does not
At 131.8 cubic feet this is generous for a push mower and a full complement of yard gear, and the wide double access makes it easy to load. It will not take a riding mower or a snow blower with attachments still mounted. Measure the mower before ordering, and if you have a bagger or a mulching kit, account for the extra bulk behind the deck.
Watch the interior width of 43.7 inches. That is fine for a mower parked nose-in but tight for anything you need to walk beside. Plan to put shelving along the back wall and the mower across the front.
Know when to skip it
Skip the Manor if you need a genuinely rigid floor you can jack a mower onto, or if you are building solo. Thin side panels are another reason to have help, because they flex while you try to align the fasteners.
Part labeling and instruction quality come up repeatedly in reviews, with bent or missing panels reported now and then. Gizoon and Suncast both get better mentions on parts support in our view, so if you are worried about service, weigh that.
4. Rubbermaid 5×6 Vertical Resin Shed – Best Walls for Pegboard and Shelving
Rubbermaid Large Vertical Resin Outdoor Storage Shed With Floor (6.2 x 4.6 Ft), Weather Resistant, Beige/Brown, Organization for Home/Backyard/Garden Tools/Lawn Mower/Bike Storage/Pool Supplies
28.72 sq ft of floor area
57 inch deep by 77.2 inch wide
Double-wall resin construction
Wall panels hold up to 75 lbs
195 pounds total weight
Pros
- Wall panels rated to hold 75 lbs for pegboard and hooks
- Double-wall resin that will not rust or rot
- Compact footprint that preserves patio space
- Tool-free assembly with an impact-resistant floor
Cons
- Heaviest of the small resin units at 195 pounds
- Padlock sold separately
- Costs more than most resin competitors
What sets the Rubbermaid apart is wall strength. The panels are rated to hold 75 pounds, which means a pegboard, shelves and utility hooks go up without any clever framing. If your plan is a mower in the corner and a properly organized tool wall on the other side, this is the shed built for it.
The floor area is 28.72 square feet on a 57 by 77.2 inch base, and the floor itself is impact-resistant, so a mower rolled in over a gravel pad is not going to punch through. It holds a push mower with the handle up, plus long-handled tools stood against the wall, without the tight squeeze you get in a 6×4.
Roughly 2900 reviews average 4.2, with 64 percent five stars. Buyers point to the small footprint, the durable panels and the fact that assembly needs no special tools. It carries UV protection and water resistance, and the double-wall construction is dent and leak resistant rather than merely weatherproof.
Two practical notes. It weighs 195 pounds empty, which makes it the heaviest of the compact resin units despite the small size, and it sits at the upper end of the resin price range. The padlock is a separate purchase, so budget for that if you are storing fuel cans.
Check your wall space before buying
Measure the wall length of your mower deck and the height of the handle when folded. Because the interior is 57 inches deep rather than square, a mower parked along the long wall still leaves about 18 inches of depth for shelving. That works if your mower is narrow, and stops working if you have a wide-deck machine with a bag attached.
Because the panels hold real weight, plan your hook spacing at stud locations rather than guessing. The 75-pound rating is per mounting area, so spreading hooks across the panel width keeps a loaded tool rack from pulling the panel inward.
Know when to skip it
Skip it if you are on a tight budget, since it sits at the upper end of the resin price range. Also skip it if you plan to hang heavy shelves loaded with paint or fertilizer cans; the panel rating is generous but it is not a stud wall, and resin will creep under sustained heavy load.
And skip it for a riding mower. At 77 inches wide on the exterior dimension, the interior is nowhere near a tractor mower.
5. Keter Store-It-Out Prime Resin Shed – Best Budget Box for a Push Mower
Keter Store-It-Out Prime 4.3 x 3.7 ft. Outdoor Resin Storage Shed with Easy Lift Hinges, Perfect for Yard Tools, Pool Floats and Garden Accessories, Black
52 inch wide by 28 inch deep
Hydraulic piston assisted lid
Interior depth about 2.66 ft
Resin with steel reinforcement
Vented with locking points
Pros
- Hydraulic pistons make the lid easy to lift
- Snap-together assembly often done in about an hour
- Quiet in rain and hail compared with metal units
- Tidier look than a plain plastic storage bin
Cons
- Wider than it is deep so long-handled tools do not fit well
- Lid can arrive warped and not sit flush
- Thin resin with some builds failing in strong wind
This is not a building, it is a large outdoor storage chest with a hinged lid on gas struts, and for a push mower in a small yard it is genuinely the smartest thing you can buy. You lift the lid with one hand, roll the mower in, and walk away. There is no door to swing into, no threshold to scrape a deck on, and no ramp angle to worry about.
The footprint is 52 inches wide by 28 inches deep by 44.7 inches tall, with 49 inches of internal height above the floor. It ranks high in the Storage Sheds category for a reason: it hides mower clutter and bags better than any open bin, and the bin-opening kit even raises trash can lids as you lift the top.
It rates 4.0 across roughly 1900 reviews with 57 percent five stars. Assembly is snap-together and owners often finish in about an hour with basic tools. Because it is resin with steel reinforcement, it is quiet in rain and hail, which matters if it sits next to a bedroom window.
The wide-and-shallow shape is the fundamental limitation. Long-handled rakes and shovels will not stand up inside because there is no depth for them, so those live on a wall rack outside. Thin panels and a lid that can arrive warped are the other recurring mentions, and one reviewer reports wind damage to the unit.
Is the security real?
Be honest about this one. Flexible locking points deter a casual thief and keep animals out, but a determined person with a pry bar gets in fairly quickly. If you are storing fuel, keep the cans locked separately rather than relying on the shed for security.
For theft deterrence generally, a shed with rigid double doors and a hasp for a padlock is a step up, and several of the metal models in this roundup ship with a lock included.
Know when to skip it
Skip it if you want to walk into the shed and reach the back wall, because at 28 inches deep you cannot stand inside. Skip it if your mower has a tall handle that will not clear 49 inches, and skip it if you have anything to store that needs to stand upright on its own.
Also skip it in exposed wind sites. It is light, tall and catch-exposed, so anchor it properly and place it where wind can pass around it.
6. Gizoon 6×4 Galvanized Metal Shed – Best for a Narrow Side Yard
Gizoon 6×4 FT Outdoor Shed, Metal Garden Shed Lockable Doors, Dark Gray
24 sq ft of floor area
75.6 inch wide by 48.5 inch deep
44.5 inch door opening
Galvanized steel with UV coating
Lock and gloves in the box
Pros
- 24 sq ft of floor for a mower snow blower or bikes
- Galvanized steel with UV-protective coating
- Metal lock and accessories box included
- Sloped roof plus integrated vents for airflow
Cons
- No floor kit so a separate base is needed
- Thin sheet metal dents and flexes during assembly
- Protective film takes time to peel off
Galvanized steel gets a bad reputation because of garden centres from fifteen years ago, and the Gizoon 6×4 is a good argument for giving it another look. At 75.6 inches wide by 48.5 inches deep it fits a side yard that a 6×4 resin shed will not take, and the 44.5-inch door opening takes a push mower or a snow blower without a fight.
The steel carries a spray-applied UV protection and a fixed-tube hinged door, and the sloped roof sheds water instead of letting it sit on the panels. Buyers like that the lock is actually in the box, along with an accessories box and a pair of gloves, which saves a second trip to the hardware store.
It holds 4.2 from about 1060 reviews with 66 percent five stars. Gizoon customer service draws specific praise for replacing missing panels, which is the thing that most often goes wrong with imported steel sheds. Assembly is a two-person afternoon, and the packaging is well labelled with installation videos available.
The one non-negotiable is the floor. There is no floor kit in the box, so you are building a gravel or concrete base yourself before assembly. That is not a dealbreaker, but it is real work and it is where most floor complaints in this category come from.
Decide on the base before you order
A steel shed with no floor will sit directly on whatever you put down, and a mower that tracks moisture into the base will rot it from below. Compacted gravel with a sand top layer drains well and is the usual choice for a shed this size. A concrete pad is better if you plan to jack something heavy or if your soil is clay that holds water.
Whatever base you choose, level it. Out-of-level sheds get doors that rub and panels that gap, and that is the single most common reason buyers describe cheap steel sheds as poor quality.
Know when to skip it
Skip it if you want a shed you can walk into and work inside, because 48.5 inches of depth does not allow that. Skip it if the thin-gauge panels bother you, and be aware they will flex during assembly and take a dent if something hits them.
It also arrives covered in a protective film that takes time to peel off every crease. Budget an hour, or leave it on and accept the slightly cloudy finish.
7. Aoxun 7.3 x 5.3 Ft Galvanized Steel Shed – Best for Snow and Wind Loads
Aoxun 8’x6′ Shed with Floor Galvanized Steel Outdoor Storage Shed Brown
48 sq ft of floor area
88 inch wide by 63.4 inch deep
12mm interlocking plastic floor
82 lb per cu ft load capacity
Rated for 6 inch snow and 25 mph wind
Pros
- 12mm interlocking floor rated 82 lb per cu ft
- Stated rating for 6 inches of snow and 25 mph wind
- Nut and bolt hardware at each panel overlap
- Corner guards and foam-cushioned packaging
Cons
- Two to four adults and three to six hours to build
- Finished footprint can run about 8 inch under nominal
- Thin formed metal flexes and dents in transit
The Aoxun is the only shed here with a published weather rating, and that matters more than it sounds. The manufacturer states the panels handle 6 inches of snow and 25 mph wind. For anyone north of the Carolinas who has watched an unanchored lightweight shed slide across a lawn in a February storm, a number to check against your local conditions is worth a lot.
It is also the only unit in this group with an interlocking 12mm plastic floor rated at 82 pounds per cubic foot. That is a real load rating rather than a marketing phrase, and it means you can put a mower, a generator and stacked bins on the floor without guessing.
Dimensions are 88 inches wide by 63.4 inches deep by 77.2 inches tall, giving 48 square feet of floor area with double doors, top ventilation vents, a stainless steel latch and reinforced hinges. The angled roof adds interior clearance at the peak. It rates 4.1 from around 670 reviews with 58 percent five stars, and ranks well in the Storage Sheds category.
Assembly is the honest drawback: two to four adults and roughly three to six hours. Newer production revisions added a nut and bolt at each panel overlap, which stiffens the structure noticeably compared with earlier screw-only versions.
Check the footprint against your pad
Reviewers report that the finished building can end up about 8 inches under its nominal footprint, so build your base with margin on all four sides. This is the most common reason people run out of room during assembly rather than at the door.
Also note the floor is included but the base is not. On compacted ground the floor will sit unevenly and rock under load, which is what owners describe when they mention a wobbling floor.
Know when to skip it
Skip it if you are assembling alone or with one helper, since four adults is the realistic figure. Skip it if your site has mature trees that drop branches, because the crush-resistant panels handle snow but not a falling limb.
Thin formed metal still dents in transit, and the protective film is tedious to remove from every crease. Both are minor compared with the floor and the weather rating.
8. Gizoon 8×6 Galvanized Metal Shed – Best Wide Door Opening for a Riding Mower
Gizoon 8 x 6 FT Outdoor Storage Shed, Galvanized Metal Garden Shed, Brown
94 inch wide by 73 inch deep
73 inch door opening
72 inch door height
UV-protected galvanized metal
Interior height about 66 inch
Pros
- A 73 inch door opening among the widest here
- Footprint suits riding mowers and snow blowers
- Arrives in a compact carton for its size
- Customer service replaced a missing panel quickly
Cons
- Interior height about 66 inch so most adults duck
- Roof seams can leak unless the screws are sealed
- Thin gable ends bend easily and the film tears
Door width is the number that decides whether a riding mower goes in easily or painfully, and the Gizoon 8×6 has one of the widest openings we tested at 73 inches. If your riding mower has a 42-inch deck, you get roughly 15 inches of clearance on each side, which is the difference between steering straight in and performing a parking maneuver every time.
The building measures 94 inches long by 73 inches wide by 76.1 inches tall, and the galvanized metal carries UV protection. It arrives in a compact box, which is unusual for a unit this size and means it is easier to bring to a side yard than the resin walk-ins.
Buyer sentiment is genuinely split, and the split is informative. At 4.0 from around 330 reviews with 61 percent five stars, some owners call it a bargain that lasts years when anchored and sealed, while others report roof leaks and bent gable panels on arrival. The recurring fix in the positive reviews is sealing the roof screws with a flexible sealant.
Watch the interior height of about 66 inches. It is tall enough for the mower and most tools but short enough that an adult has to duck, so this is a store-and-close building rather than a place to work.
Get the opening, then the height
The 73-inch opening easily handles a riding mower with a deck up to about 54 inches. A zero-turn with a 60-inch deck plus the steering levers turned is a different problem, and for that you want a 10×12 with a proper wide double door rather than an 8×6 with a single wide door.
Measure the height of your mower at the highest point too, including the steering wheel. On a mower with a high-back seat you will be scraping the header on the way in, and that is how the gable ends get bent.
Know when to skip it
Skip it if you want to stand upright inside, if you live in a heavy-snow area and will not seal the roof screws, or if you are bothered by thin gable ends that arrive bent.
It also has no floor kit, so plan the base. Several owners report one unit that has held up for three years outdoors, but that is with anchoring and sealing done properly.
9. Greesum 8×6 Galvanized Steel Utility Shed – Best for Overlapping Wall Panels
Greesum 8x6FT Outdoor Storage Shed Utility Tool Shed, White
93.9 inch wide by 71.5 inch deep
Thicker galvanized steel panels
Overlapping walls for water resistance
Sloped roof
Lockable hinged door
Pros
- Thicker galvanized steel with overlapping wall panels
- Sloped roof that drains and adds usable space
- Lockable hinged door deters animals and theft
- Protective film guards against scratches in handling
Cons
- Instructions recommend gloves for sharp metal edges
- Two-person build recommended at this size
- Check local HOA policy before placing a large shed
The Greesum 8×6 stands out for one specific reason: overlapping wall panels in thicker galvanized steel. Overlap is what separates a shed that sheds water from one that leaks at every seam, and it is the detail most budget steel sheds leave out in favour of cheaper single-skin panels.
At 93.9 inches wide by 71.5 inches deep by 74.2 inches tall, it holds a riding mower, a snow blower and stacked bins. The sloped roof adds usable height at the ridge and stops rainwater pooling on the panels, and the lockable hinged door keeps animals and opportunistic thieves out.
We found no customer photos for this unit, so our read is based on the roughly 350 reviews behind its 4.0 rating with 55 percent five stars, and on what buyers consistently praise: the steel gauge, the panel overlap and the roof.
Manufacturer guidance is practical. They recommend a helper and gloves, and they tell buyers to check local HOA policy before placing a unit this size in a backyard, which is a courtesy worth repeating because it is a genuine source of frustration.
Decide on anchoring and base together
Overlapping panels add stiffness but do not stop wind uplift. Whatever the shed walls are made of, a shed with ground anchors driven into the base edge will survive weather that takes an unanchored neighbour apart. Combine that with a compacted gravel base and you address the two complaints we see most in this category.
Leave four to six inches of air gap between the shed base and the fence line where you can. It helps drainage and keeps the walls from sitting in wet grass.
Know when to skip it
Skip it if sharp-edged galvanized steel during assembly is a dealbreaker for your household. Wear gloves, and expect the two-person build.
Also check your lot rules before you order. A shed this footprint can trip a setback requirement even where no permit is needed, and moving a built unit is a much bigger job than choosing the right spot the first time.
10. Flamaker 6×8 Metal Shed – Best for Corrosion Resistance and Corner Protection
Flamaker 6×8 FT Storage Shed Waterproof Metal Garden Shed with Lockable Door Utility Tool Shed Outdoor Storage for Backyard, Patio and Lawn, Brown
48 sq ft of floor area
89.7 inch wide by 73 inch deep
64.1 inch door height
Coated galvanized steel
Roof corner protection caps
Pros
- Coated galvanized steel resists rust and corrosion
- Protection caps over roof corners and protruding screws
- Hinged door easier to open and close than a sliding design
- 48 sq ft of floor in a 6x8 footprint
Cons
- No floor included so a base is needed for weather protection
- Thin metal panels that dent in transit
- Single door gives a narrower clear opening than double doors
Corrosion is where steel sheds fail, and the Flamaker attacks it at the points that matter. The galvanized steel carries an additional coating layer for rust and corrosion resistance, and the manufacturer fits protection caps over all four roof corners and over every protruding screw. Screws are where water sits and where rust starts, so capping them is a real improvement.
The shed measures 89.7 inches wide by 73 inches deep by 76.1 inches tall with a 64.1-inch door height and 48 square feet of floor area. That is enough for a riding mower plus a slim shelving run, and the sloped roof increases usable height at the peak while keeping stored items dry.
It holds 4.1 from around 250 reviews, with 56 percent five stars and a fairly large four-star share at 24 percent. That distribution tells you the sentiment is broadly positive but not glowing, which fits a unit at this price point. The common owner themes are the coated steel, the capped corners and screws, and the door hardware.
General consensus in this category, echoed here, is that metal sheds perform best when paired with a proper base. Without a floor the bare ground stays damp and the frame works against wet soil year after year.
Where corrosion starts on a steel shed
Three places to inspect after the first wet season: the base rail where the wall meets the ground, the screw heads, and the roof seams. The Flamaker caps two of those three by design. The base rail is the one you manage, by keeping the shed on a raised gravel bed so the steel never sits in mud.
Touching up a scratch with exterior-rated zinc paint in the first year is five minutes of work that prevents the slow creep that ruins cheap sheds over a decade.
Know when to skip it
Skip it if your mower needs a wide, straight-in entry, because a single door gives you a narrower clear opening than a double-door shed of the same width. Measure your mower across the deck first.
Skip it if you are not prepared to build a base, and skip it if thin metal panels that dent in transit bother you. Otherwise the coated steel and the corner caps make this a solid choice for a damp climate.
11. Vongrasig 5 x 3 x 6 Ft Metal Shed – Best for Hand Tools on a Budget
Vongrasig 5 x 3 x 6 FT Outdoor Storage Shed Clearance, Metal Garden Shed with Large Window and Lockable Door, Anti-Corrosion Waterproof Tool Shed for Backyard Patio, Lawn (Dark Gray)
12.11 sq ft of floor area
59.1 inch wide by 29.5 inch deep
29.5 inch door opening
Acrylic window with side vents
Lockable door and 74.8 lb weight
Pros
- Low-cost entry into shed storage with a useful footprint
- Large acrylic window plus side vents for light and air
- Thick steel plates with deep ribs and a coated surface
- Wood edge boards and a pair of gloves in the carton
Cons
- Interior too tight for a generator or a large tote
- Thin metal flexes and holes do not always align
- Several hours of two-person work with unclear instructions
Be clear about what this one is: a low-cost outbuilding for hand tools, hoses, gas cans and small gear. At 12.11 square feet and a 29.5-inch door opening, it will not take a riding mower and most owners say it will not take a generator or a large tote either. Buyers consistently treat it as an inexpensive home for the clutter that otherwise lives on the garage floor.
It sits at the low end of what these sheds cost, and the build quality is better than that suggests. The steel plates are thick with deep ribs, the surface is coated, and the packaging includes wood boards at the edges plus a pair of gloves, which reduces transit damage more than most brands bother with.
The acrylic window and side vents are the feature owners mention most, because they turn a dark metal box into something you can actually find things in. The door is lockable and the roof is waterproof with corner protection caps, and at 74.8 pounds it is light enough to carry into position before assembly without a dolly.
It holds 4.0 from roughly 360 reviews with 55 percent five stars. Assembly is a two-person job of several hours, instructions are not well ordered, and the thin metal flexes enough that hole alignment takes patience.
Will your mower fit through a 29.5-inch door?
Only a small walk-behind, and even then measure it. A 16 to 19-inch push mower deck gives you 22 to 25 inches across the deck, so the machine clears the opening, but you will be steering it rather than driving it straight in. With the handlebars turned, the effective width grows.
If your goal is mower storage plus somewhere for the rake and the spare fuel can, this does that job at a very low cost. If your goal is a mower you can actually work on, look at a unit with more depth.
Know when to skip it
Skip it for a riding mower, a snow blower, or anything with a wheelbarrow-sized footprint. Skip it if you need shelving, since none is included and the interior is too shallow to mount any.
It is also worth pairing with an anchor kit, because a lightweight metal shed in an exposed position is exactly the profile that tips over in a windstorm.
12. Patiowell 6×4 Resin Shed – Best for a Wipe-Clean Floor and Compact Footprint
Patiowell 6×4 FT Resin Outdoor Storage Shed with Floor, Light Gray
22.76 sq ft of floor area
67.1 inch wide by 48.8 inch deep
48.4 inch door opening
Lockable door with vent and window
Plastic floor base included
Pros
- UV-resistant resin that wipes clean easily
- 22.76 sq ft floor sized for a mower and pool gear
- Sloped roof with a built-in window and vent panel
- Sturdy plastic floor base in the box
Cons
- Hollow resin walls feel flimsy for mounted shelves
- Assembly can run six or seven hours
- Included combination lock is of low quality
The Patiowell 6×4 is a compact resin option with a door opening wider than most sheds in its class. At 48.4 inches across the door and 22.76 square feet of floor, it takes a push mower, garden tools, pool supplies and a bike without turning the mower sideways first, which is more than most 6×4 sheds can claim.
The resin exterior is UV resistant so it does not fade the way lighter plastic does, and the surfaces wipe clean, which matters after a season of wet grass clippings. The sloped roof, the vent panel and the built-in window keep airflow moving so you are not opening a damp box.
It holds 4.0 from around 170 reviews with 62 percent five stars and ranks well in the Storage Sheds category. Buyers like the clean look, the included floor and the interior volume being larger than expected for the footprint.
The critical reviews focus on the walls being hollow, which is why they feel thin when you knock on them and why we would not hang shelves on them. The floor can also wobble even on a level base. Assembly can run six or seven hours, the instructions and video disagree in places, and the included combination lock is weak enough that many owners replace it with a padlock hasp.
Plan for the split delivery
This unit arrives in two boxes that may reach you at different times. Build the base for the full footprint before the first box lands, because you cannot assemble one half meaningfully without the other. It is a small logistics point that saves an argument.
On the floor, if you want something rigid, lay a sheet of plywood over the included plastic base. That single addition fixes the flex that owners describe and gives you a surface you can jack a mower onto.
Know when to skip it
Skip it if you plan a wall of pegboard and shelves, because hollow resin panels will not take that load. Skip it if you want to be inside the shed standing up, since 48.8 inches of depth is a reach-in space.
Also skip it if long assembly time bothers you. Between the two-box delivery and a build that runs past six hours, this is one of the least convenient units here despite the easy-care exterior.
What Size Shed Do I Actually Need? Measure the Mower First
Measure the machine, not the marketing photo. The number that matters is your mower’s widest point, which is the deck and wheels, not the handlebars. Add four inches of clearance for steering, then add two to three feet of walk-around space on the side you will use most.
Push mower and hand tools: a 6×4 with at least a 32-inch door opening. The Suncast 54 and the Keter Manor both go wider than this.
Riding mower only: an 8×10 with a 50-inch opening at minimum. The Gizoon 8×6 at 73 inches gives you real steering room.
Zero-turn with a 48 to 60-inch deck: a 10×12 or larger, with a door opening of 64 inches or more. Anything smaller means a fight every time.
Mower plus workbench and tools: go up one size from the mower alone. Most sizing regret comes from buying the exact fit and then having nowhere for the rake.
The pattern we see again and again in buyer feedback is regret at buying the minimum that fits. If your measurements land you exactly on a limit, step up one size. The difference in cost between an 8×6 and an 8×10 is small compared with rehembling a mower deck because you had no clearance.
If you are still deciding what to store, our best electric lawn mowers and best robot lawn mowers roundups cover the machines with the smallest storage footprints, since an electric mower with a removable battery takes up a fraction of what a tractor mower needs.
Door Width, Ramp Angle and Walking Clearance
Door opening width is the spec almost nobody publishes, which is why so many buyers discover the problem on delivery day. Measure the clear width with the doors fully open, not the building width. A shed advertised as 6 feet wide may give you a 44.5-inch opening once the frame and hinges take their cut.
Ramp angle is the second detail that ruins mower decks. The general rule is to keep the ramp slope at or under about 10 degrees for a riding mower with a wide deck, and to build a ramp rather than trying to lift a mower over the floor lip. A threshold that is even an inch too tall becomes a scraping point on every entry.
Walking clearance is what turns a shed into a usable space. If you can only open one door and step sideways past the mower, every stored item becomes a moving-the-mower exercise. Double doors plus two feet of side clearance means you reach the back wall without moving anything.
Resin vs Galvanized Steel vs Wood: Which Material Wins
Resin sheds such as the Suncast 54, Keter Manor, Rubbermaid 5×6 and Patiowell 6×4 need no painting, will not rot or rust, and are quiet in rain. They are lighter to handle, include a floor more often, and fade or get brittle after a few seasons of hard UV exposure.
Galvanized steel units such as the Gizoon, Aoxun, Greesum, Flamaker and Vongrasig give you more square footage per dollar and usually a wider opening, but they need a base, they dent in transit, and they rust at seams and base rails when you do not seal them.
Pressure-treated wood and vinyl kits are the choice when you want a workshop look and the ability to run wiring, but they demand regular painting or staining and take far longer to build. For mower storage alone, we rarely think the maintenance justifies itself.
Foundation, Anchoring and Permits
Compacted gravel with a sand top layer is the usual answer for a shed up to 8×8: it drains, it is affordable, and it can be levelled with a rental plate compactor. Concrete is better for the large walk-ins and for anything you plan to jack. Pressure-treated skids work for small resin sheds. Whichever you use, level it and leave a small gap between the shed base and surrounding grass.
Anchor the shed to its base with ground anchors regardless of material. Unanchored sheds are the ones that end up on a neighbour’s lawn after a storm, and anchoring takes an afternoon with a drill and a hammer.
Permits usually kick in around 100 square feet of floor area or 8 feet of wall height, though the exact threshold is set by your municipality. Setback rules are commonly 5 to 10 feet from a property line, and HOAs frequently impose their own limits. Check both before ordering, because moving a built shed is a much bigger job than picking the right spot.
Preparing a Gas Mower for Months in Storage
Storing a mower with fresh gasoline in an enclosed resin shed is the one genuine safety question here. Fuel vapour is heavier than air and pools at floor level, so run the shed’s vents when the mower is inside, keep fuel in an approved container with a tight lid, and never run the engine inside a closed shed.
Before it goes in, drain the fuel tank or run it out and add stabiliser, disconnect and top up the battery, clean grass out from under the deck, sharpen and oil the blade, inflate the tires, and drop a cover over the machine. Sharpening the blade in autumn means the mower is ready to cut properly on the first spring morning rather than tearing the grass for a week.
Store fuel cans separately from the mower where you can, and if you store a battery-powered mower the same way, keep it off concrete and charge it once a month. Our cordless mower guide covers which batteries tolerate long storage best.
Frequently Asked Questions
What size shed do I need for a lawn mower?
A push mower needs a 6×4 shed with a door opening of at least 32 inches. A riding mower needs an 8×10 with a 50-inch opening at minimum, and a zero-turn with a wide deck needs a 10×12 or larger with a 64-inch opening or more. Measure your mower at its widest point and add four inches of steering clearance.
Is an 8×10 shed big enough for a riding mower?
Yes for most riding mowers with a deck up to about 48 inches, provided the door opening is 50 inches or wider. You also want two to three feet of walk-around space so you can reach stored items without moving the mower. For a zero-turn with a 54 or 60-inch deck, step up to a 10×12.
Is it a good idea to store my lawn mower in a shed?
It is a good idea for any small-engine mower. A dry shed keeps rust off the deck and frame and protects the engine from weather. Run the shed vents whenever the mower is stored indoors, keep fuel in approved containers, drain or stabilise fuel before long storage, and never run the engine in a closed shed because vapour is heavier than air.
What is the best foundation for a lawn mower shed?
Compacted gravel with a sand top layer is the best value for sheds up to 8×8 because it drains well and is easy to level. Concrete is better for large walk-in buildings and anything you plan to jack. Pressure-treated skids work for small resin sheds. Whichever you choose, level it fully and anchor the shed to it with ground anchors.
Do I need a permit for a storage shed?
In many municipalities a permit is required once a shed exceeds roughly 100 square feet of floor area or 8 feet of wall height, though the threshold varies by location. Setbacks of 5 to 10 feet from a property line are common, and HOAs often add their own rules. Check your local building department and HOA before ordering.
The Bottom Line: Which Shed to Buy
For most people with a push mower and a garage already full, the Suncast 54 Cu Ft vertical resin shed is the pick. It has the highest rating in the group, a ten-year warranty, a 46-inch opening and shelf notches, in a footprint that fits beside a house rather than in the middle of a lawn.
If you own a riding mower, the choice is between the Suncast Tremont 8×10 for walk-in space and light, or a metal 8×6 such as the Gizoon at 73 inches of door opening if you want to steer straight in and would rather build the base yourself. For a zero-turn with a 54 or 60-inch deck, neither is big enough and you should be looking at 10×12 buildings.
Whichever one you pick, measure the mower, check the door opening in inches, level the base and anchor it down. Those four steps solve almost every complaint we read about the best storage sheds for lawn mowers in 2026.
