A resin shed earns its keep the first winter it keeps a mower dry and the first spring you can actually find the pruning shears. Wood sheds need paint and patience. Metal sheds dent and sweat. Resin, done right, just stands there and does the job.
The catch is size. Most buyers measure the shed and forget to measure what goes inside it: the mower’s handle height, the bike’s handlebar width, the door swing. The three sheds below cover the three real situations — a big backyard workhorse, a mid-size all-rounder, and a narrow vertical shed for a side yard. One common mistake sits at the end, and it is the one to avoid.
At a Glance
| Shed | Size | Best for | Watch out for |
|---|---|---|---|
| Keter Artisan 9×7 | 9 x 7 ft, Duotech walls, floor included | Mowers, bikes, and bulky gear | Needs a level base and two people to build |
| Keter Factor 6×3 | About 70 x 44.5 x 82 in, 110 cu. ft. | One mower plus tools | Narrow depth limits wide equipment |
| Suncast Vertical Shed | About 32 x 26.5 x 70.5 in, 20 cu. ft. | Tools and a narrow side yard | No mower fits inside |
Best Overall: Keter Artisan 9×7 Outdoor Shed
The Artisan 9×7 is the shed to buy when you want the storage problem solved once. Its Duotech walls carry a wood-like texture with the weather resistance of resin, and the listing rates it waterproof with UV protection. A floor is included, which matters more than it sounds: a shed without a floor invites damp, mud, and mice through the bottom edge.
At 9 by 7 feet with an 85.8-inch chamber depth, it holds a walk-behind mower, bikes, and the usual garden tools without a game of sliding puzzle every Saturday. Double doors mean wide items go in straight instead of at an angle. The limited lifetime warranty from Keter is the strongest of the three picks here.
The honest trade-off is the build. This is a two-person, level-base job, and a shed this size punishes a sloped or soft pad. If your yard has no flat spot, budget for a gravel or paver pad before the shed arrives, not after.

Runner-Up: Keter Factor 6×3 Resin Shed
The Factor 6×3 is the right shed for a yard that needs a mower home, not a workshop. Its external footprint is about 70 inches wide by 44.5 inches deep and 82 inches high, with 110 cubic feet inside and a skylight that keeps the interior from being a dark cave. Steel reinforcement and a five-year warranty back the polypropylene resin shell.
It fits a push mower, a string trimmer, and shelved hand tools comfortably. What it does not fit is a riding mower or anything wide: the 44.5-inch depth is the number to check against your mower’s length before ordering. If the mower fits, this is the better buy than the bigger Artisan — less pad, less assembly, less money tied up in empty air.

Best Small Space: Suncast 20 Cu. Ft. Vertical Shed
Not every yard has room for a shed, and not every shed needs to hold a mower. The Suncast vertical shed is about 32 inches wide and 26.5 inches deep, standing 70.5 inches tall, with double doors and roughly 20 cubic feet inside. Its double-wall resin construction will not rust or rot, and at 65 pounds it can be moved by one person.
This is the pick for a side yard, a patio corner, or a townhouse strip where a full shed would eat the whole garden. Long-handled tools, a hose, fertilizer bags, and a folding chair fit. A mower does not, and that is the point: buy this when the job is tool storage, and stop pretending it can be a garage.

The One to Skip: A Small Horizontal Box as a Mower Shed
Small horizontal storage boxes are excellent deck boxes — they are terrible mower sheds. The lid opens from the top, the interior height is short, and a mower handle either will not fit or has to be folded and wrestled every time. Owners who buy one for a mower end up storing the mower in the garage anyway and the box full of cushions.
That is not a knock on deck boxes. Our guide to the best deck storage boxes covers where they shine. It is a reminder to match the container to the contents: if it has wheels and an engine, it needs doors, not a lid.
Before You Order
Measure three things, in this order: the widest item going inside, the tallest item with its handle up, and the door opening, not just the shed’s footprint. Then check the pad. A resin shed on soft ground will rack, and a racked door is the most common reason a weatherproof shed starts leaking.
For the sizing math — footprint, height, and door width worked through item by item — see what size storage shed you need. And if you are still deciding between materials, resin vs metal vs wood sheds lays out which one lasts longest outdoors and where each one loses.
Bottom Line
Buy the Artisan 9×7 if you have the space and the gear to fill it. Buy the Factor 6×3 if one mower and some tools are the whole job. Buy the Suncast vertical shed if space is tight and tools are all it needs to hold. And whatever you buy, measure the mower before you measure the shed.
