If you only read one thing
Buy the 8x6 if a mower and a wheelbarrow both have to fit, the 4x6 if the mower goes in alone.
An 8x6 resin shed at $650 to $1,000 takes a walk-behind mower through a 54-inch door with room for the wheelbarrow and the tools beside it. A 4x6 at $320 to $550 takes a 21-inch mower through a 25-inch door and not much beside it. Both come with a floor, both need a level pad and anchors, and neither needs a permit in most places. A riding mower moves you to the 8x7 and 8x10 sheds with 60-inch doors.

Resin Sheds Compared by Size
Five sizes, and the size is most of the decision. These are category picks from the manufacturers' published specifications and the listings, not from building each shed ourselves.
Typical price ranges for the category, not live listings. Amazon prices change frequently, so click through for current pricing and availability.
Vertical Sheds
A walk-up cabinet, not a walk-in. Six and a half feet tall on a four-foot footprint, for the gear that does not fit in the garage.
Best for
Patios, side yards, townhouse lots, a first shed
Top pick
Suncast XL Vertical, 106 cubic feet behind a 64-inch door opening
What works well
- Double doors open the whole front, so nothing hides behind anything
- Floor included on the Suncast XL
What to consider
- You reach in. There is no stepping inside
- A mower fits only in the largest sizes
- Light enough that it wants anchoring in wind
Small Walk-In Sheds (4x6)
The first real shed: tools, the push mower, the cushions and the bikes, with a door you walk through.
Best for
Yards with a mower and a growing tool pile, no room for an 8-footer
Top pick
Keter Darwin 4x6 for the ratings, the Patiowell 6x4 in the table for the price
What works well
- 129 cubic feet on the Keter Darwin, with a window and a skylight
- Rated for 65 mph wind and 15 psf of snow
- About two hours with two people
What to consider
- A 25.5-inch door takes a push mower, not a rider
- No room to turn around with a mower inside
- The budget imports publish no load ratings
Mid-Size Sheds (8x6)
The size most yards need: a walk-behind mower, the wheelbarrow and the tools with a path between them.
Best for
A mower plus everything else, on a yard that cannot spare 8x10
Top pick
Keter Factor 8x6, the only 8x6 here with published wind and snow ratings
What works well
- A 54.5-inch double door clears a walk-behind mower
- 285 cubic feet with a skylight and a window
- Floor has eight marked anchor points
- Ten-year limited warranty
What to consider
- Two people and most of a day to assemble
- 15 psf snow rating wants the roof cleared in a heavy winter
- Needs an 8x6 level pad plus room to open the doors
Full-Size Sheds (8x7 to 8x10)
The garage overflow shed: a riding mower through 60-inch doors, shelving on the walls, room to stand.
Best for
Riding mowers, bikes plus mower, a yard with a real tool collection
Top pick
Suncast Tremont 8x10 for the door, the Lifetime 8x10 in the table for snow country, the Patiowell 8x10 in the table on a budget
What works well
- 60-inch door openings on the Suncast Tremont models
- Metal trusses and reinforced floors rated for a mower
- Roof loads of 23 psf on the Lifetime 8x10 and 20 psf on the Suncast Tremont 8x10
- Skylights, so you can find things without a lamp
What to consider
- Retailers list four to eight hours with two or three people, and the 8x10 is a 490-pound pile of panels
- The 8x10 needs an 85-square-foot pad plus clearance all around
- The budget imports are rated for 46 mph wind, not 65
Horizontal Sheds
A lidded box for trash cans, cushions and pool gear, 34 to 98 cubic feet. Fits under a window or against a fence.
Best for
Trash and recycling cans, patio cushions, pool toys, renters
Top pick
Keter Store-It-Out for cans, a lidded horizontal for cushions and pool gear
What works well
- Lid and doors open together, so a full-height can rolls out
- Low enough to sit under a window
- The cheapest way to get cans and cushions out of sight
What to consider
- No standing storage and no shelving
- Lids collect leaves and snow
- Anchor it or it walks in wind
How to Choose a Resin Shed
The size decides the price, the base decides whether the doors close, and the anchors decide whether it is still there after the first storm.
Size by the biggest thing going in
Measure the mower, not the yard. A 21-inch walk-behind mower is a little over two feet wide and rolls through the 4x6's 25.5-inch door, then takes most of the floor. Add a wheelbarrow or a second wheeled thing and you want the 8x6's 54-inch door and 93 inches of width. A riding mower needs the 58 to 60 inch doors and the floor length of the 8x7 and 8x10 sheds, plus a ramp, and it takes the middle of the floor, so the tools go on the walls. If nothing with wheels is going in, the 4x6 holds a family's hand tools and cushions with room left, and the vertical shed holds them on a patio.
The floor is in the box, the base is not
All nine sheds ship with a resin floor panel. What none of them ships with is the level surface it has to sit on. A compacted gravel pad inside a timber frame is the common choice and drains well. Pavers over gravel or a concrete slab also work. Build it a few inches larger than the shed on every side, and check level in both directions before the first wall goes up. An out-of-level base is why the doors will not close.
Anchor it, whatever the rating says
The 65 mph wind figure on the Keter sheds is for an anchored shed on a proper base. Keter marks eight anchor points in the Factor's floor. Suncast sends you to the hardware store for 3/8-inch masonry anchors, and the Tremont 8x10 manual calls for 16 of them. Keter's manual says proper screws at the marked floor points, not included. Lifetime sells an Extreme Weather Kit that adds anchoring channels and takes its 8x10 to a 94 mph rating. An empty resin shed weighs roughly 120 to 500 pounds and is mostly wall, so anchor it the day it goes up.
Permits and setbacks
The largest shed here, the Suncast Tremont 8x10, covers about 85 square feet. The 2021 model residential code exempts one-story detached sheds up to 200 square feet from a building permit, and the 2006 edition and some states, California among them, use 120. Setback rules from the property line and easements apply regardless, and an HOA can have its own. One call to the building department before the pad goes in settles it.
Door width and the ramp
The table lists the clear opening, not the panel. The floor sits a few inches above the pad, so plan on a ramp.
What not to put in it
A resin shed is dry, not conditioned. In summer sun the inside runs well above the air outside, and in winter it matches the cold. Paint, propane, electronics, paper, photos and anything upholstered stay in the house or go to climate control. The long-term storage guide covers that call. Sealed bins keep the cushions and the holiday gear fine. The seasonal storage guide has the rotation.
Tips Before You Order
The anchors are a separate purchase for every shed here, and the 8-foot sheds are a two-person build.
- Add two feet to every side of the footprint. The doors swing out, the roof overhangs, and you need to walk around it.
- Check the delivery weight. An 8x10 arrives as several boxes totaling near 500 pounds, sometimes on a pallet. Have a plan for the driveway.
- Count the people. Keter lists two adults for the Factor, and retailers list two or three for the Suncast Tremonts. The roof panels are the reason.
- Buy the anchors with the shed. None of these ship with them, and the Lifetime weather kit is a separate listing.
- Plan the shelving before the walls close. Suncast, Lifetime and the Keter Factor include shelves with their 8-foot sheds. Check the listing for the others. Wall space is why you buy the 8-footer over the 4x6.
Resin Storage Shed FAQ
Prices and links for every shed in the comparison table are above, and the horizontal sheds are on their card.
Do resin sheds need a foundation?+
Yes, a level one. Every shed here ships with a floor panel, and the panel needs a flat base under it or the doors will not line up. Bare lawn does not count, and neither does a slope you meant to fix later. The Keter Factor's floor has eight marked anchor points for tying it to the base.
Do I need a permit for a storage shed?+
Usually not at these sizes, but ask before the pad goes in. The largest shed here covers about 85 square feet, under both the 200 square foot exemption in the model code since 2009 and the 120 that some states keep. What the exemption never waives is the setback from your property line or an HOA rule.
Can a riding mower fit in a resin shed?+
In the 8x7 and 8x10 models. Door openings run 58.3 inches on the Lifetime 8x10 and 60 on the Suncast Tremont sheds, with floors rated for a mower. The Keter Factor 8x6 has a 54.5-inch door but only 64 inches of interior depth, so a lawn tractor goes through the door and does not fit behind it, and only the shortest rear-engine riders squeeze in. A 4x6 takes a 21-inch walk-behind mower and nothing wider.
How much snow and wind can a resin shed take?+
Roof loads run 15 pounds per square foot (psf) on the Keter Factor and Darwin, 20 psf on the Suncast Tremont 8x10 and 23 psf on the Lifetime 8x10. Keter publishes 65 mph for the Darwin and Factor, Patiowell 46 mph, and retailers list the Tremont 8x10 at 55 to 65. Lifetime's Extreme Weather Kit takes its 8x10 to 94 mph. In snow country, clear the roof after a heavy fall and anchor every shed.
What should I not store in a resin shed?+
Anything that heat or damp would ruin. A closed resin shed in July sun is hotter inside than out, and none of these are insulated. Give it the mower, the tools and the bikes, and the cushions in sealed bins. Keep whatever melts, warps, rusts or fades in the house, and keep propane out of any closed box.
Resin, metal or wood?+
Resin for the least upkeep. It does not rust, rot or need paint. Keter, Suncast and Lifetime each carry a 10-year limited warranty, and two people build one in an afternoon. Metal is cheaper per square foot but dents and sweats. Wood looks better and can be built to any size, but at these sizes it costs more and wants paint every few years.
