Best Outdoor Storage Sheds Under $800
Patio cushions sitting in garbage bags through November is not a storage strategy. A real shed keeps your outdoor gear dry, organized, and ready to go when spring hits.
These six picks cover everything from a compact 4x6 resin unit that fits behind a fence gate to a 6x8 model that handles cushions, a mower, and a bag of potting soil without breaking a sweat. All are under $800 and available on Amazon.
Every option here has lockable doors, genuine weather resistance, and assembly that one person can realistically handle on a weekend afternoon. Here is what to buy depending on how much you have to store and how much space you are working with.
1.Best Compact Resin Shed for a Small Patio
The Keter Factor 4x6 is the shed most people should buy first. It fits in a 4-foot gap along a fence line, holds six to eight standard patio chair cushions on its own, and costs under $350. The double-wall resin construction handles freeze-thaw cycles without cracking, which is more than you can say for cheaper thin-walled plastic options.
Assembly runs about two to three hours for one person. The floor panel is included, which puts it ahead of most competitors at this price. The doors have a built-in padlock loop so you can add your own lock. This is the right call for a 10x12 patio where you just need to clear out the cushions and small gardening supplies before a storm.

A genuinely compact resin shed with an included floor panel, padlock loop, and double-wall construction that holds up through hard winters.
Shop on Amazon →2.Best Horizontal Shed for Low-Profile Storage
If you have an HOA, a low fence, or just do not want something that blocks your view, the Suncast BMS4900D Stow-Away Horizontal Shed is worth a close look. It sits about four feet tall instead of the usual six to seven, which makes it nearly invisible behind a row of shrubs. It holds roughly 99 gallons of gear, enough for two sets of cushions or a coiled hose plus small yard tools.
The lid lifts up like a chest, which takes some getting used to if you are accustomed to swinging doors. But it is genuinely convenient for grabbing things quickly, and there are no doors to blow open in wind. It locks with a standard padlock. On a side yard or narrow patio strip, this beats a taller shed by a wide margin.

A low-profile horizontal shed that disappears behind landscaping while holding cushions, hoses, and small tools without the visual bulk of a vertical unit.
Shop on Amazon →3.Best Steel Shed for Heavy-Duty Tool Storage
Resin has its place, but if you are storing heavy tools, a walk-behind mower, or anything with sharp edges, steel takes more abuse. The Arrow Shed Classic 8x6 is a galvanized steel unit with a baked-enamel finish that resists rust, and at $449 it gives you 48 square feet of floor space without the cost of a wood kit shed.
The extra floor space in an 8x6 layout is meaningful. You can park a small mower on one side and stack cushions on the other without them touching. Arrow sheds require a concrete pad or gravel base since no floor panel is included, but the anchor kit ships with it. Plan for a four to five hour build with one helper. This one earns its keep on larger suburban lots with real lawn equipment to protect.

A galvanized steel shed with baked-enamel finish and 48 square feet of real storage space for mowers, tools, and bulky patio gear.
Shop on Amazon →4.Best Heavy-Duty Resin Shed for Year-Round Use
Lifetime makes outdoor storage products the same way they make folding tables, overbuilt for long-term use. The Lifetime 8x5 Outdoor Storage Shed uses high-density polyethylene panels reinforced with steel instead of wood or thinner resin, which means it will not fade, splinter, or bow under a heavy snow load. The steel reinforcement inside the walls is the key detail that separates it from cheaper HDPE options.
The 8x5 footprint is a bit unusual, more of a wide rectangle than a square, which actually works better in tight side yards. It includes a floor panel, skylights in the roof panels for natural light inside, and a padlockable door hasp. At around $549, it sits in the middle of this list but delivers a level of construction quality you would expect from something that costs twice as much.

Steel-reinforced HDPE panels, a built-in floor, and roof skylights make this one of the most durable mid-range sheds available under $600.
Shop on Amazon →5.Best Mid-Size Shed for a Full Backyard Setup
When you have patio furniture cushions, a bag of birdseed, a pressure washer, and a set of folding chairs all competing for space, a 4x6 shed stops being enough. The Keter Darwin 6x8 gives you 48 square feet of floor space plus a built-in shelf unit and overhead storage. It handles a full outdoor dining set worth of cushions without stacking them dangerously high.
The Darwin's double-door design is wider than most sheds in this class, which matters when you are trying to wheel a mower or carry a large bin in and out. It has a built-in ventilation system to prevent mold on stored fabrics, a padlock loop on both doors, and a floor panel included. At $679, it is one of the best values for a family that genuinely uses its backyard gear all summer and needs somewhere to put it all in October.

A 48-square-foot resin shed with built-in shelving, wide double doors, and ventilation to protect cushions and gear through the full storage season.
Shop on Amazon →6.Best Lean-To Vinyl Shed for Side Yards
Not every backyard has room for a freestanding shed. If you have a side yard strip alongside your house or fence, the Duramax Sidemate 4x8 Plus Vinyl Shed solves the problem with a lean-to design that sits flush against a wall. It is four feet deep and eight feet wide, which adds up to more usable space than the footprint suggests, and the whole thing blends into a white or gray house exterior without looking out of place.
Vinyl construction means no repainting, no rust, and no warping from repeated wet-dry cycles. The Duramax panels are notably thicker than the big-box store vinyl options, which comes through in how solid the door feels when you close it. This is a strong pick if you garden seriously and need somewhere to store clay pots, soil bags, and long-handled tools that would not fit neatly in a standard upright shed.

A lean-to vinyl shed that mounts against a wall or fence, ideal for side yards where a freestanding unit simply would not fit.
Shop on Amazon →Quick Tips for Buying and Setting Up a Backyard Shed
Measure your space with tape, not your eyes. A 6x8 shed needs clearance on at least two sides for door swing and for you to work during assembly. Mark the footprint with stakes before you order.
Anchor it even if the directions call it optional. A filled shed can still shift or tip in a hard windstorm. Most kits include an anchor system. Use it, especially if you are on an open lot.
Add a gravel pad if no floor panel is included. Steel sheds especially need a flat, level surface to avoid the frame racking over time. A 4-inch gravel base handles drainage and holds level through freeze-thaw better than bare concrete in most climates.
Put wall hooks in before you fill the shed. Long-handled tools leaning against the wall take up enormous floor space. A set of wall-mount tool hooks costs $15 and effectively triples your usable storage on day one.
Check local permit rules before you build. Many municipalities require a permit for permanent structures above 100 to 120 square feet. Sheds in this price range rarely hit that threshold, but a five-minute call to your city office is worth it.

Frequently Asked Questions
What is the best outdoor storage shed for under $800?
The Keter Darwin 6x8 at $679 offers the best combination of size, durability, and built-in organization for most backyards. If you need something more compact, the Keter Factor 4x6 at $349 is the better starting point.
Do resin sheds hold up in cold winters and heavy snow?
Quality resin sheds from brands like Keter and Lifetime are designed for year-round outdoor exposure. Double-wall resin does not crack in freeze-thaw cycles the way thin plastic does. For heavy snow loads, check the manufacturer's roof rating and knock off accumulated snow if it gets significant.
How long does it take to assemble an outdoor storage shed?
Most resin sheds in this size range take two to four hours for two people working at a normal pace. Steel sheds like the Arrow Classic can run four to five hours. A second set of hands is not strictly required but makes managing the wall panels much easier.
Can I fit a lawn mower in a 4x6 shed?
A standard push mower fits in a 4x6 shed, but it will take up most of the floor space. If you need to store a mower plus cushions or other gear, move up to at least a 6x8 model like the Keter Darwin.
Do outdoor storage sheds need a foundation?
Resin sheds with included floor panels can sit on level ground, though a gravel base helps with drainage. Steel sheds almost always need a level concrete or gravel pad to stay square and keep the metal framing from racking over time.
