Best Backyard Outdoor Storage Sheds

Backyard outdoor storage sheds are one of the best investments grillers can make.

An outdoor storage shed reduces clutter, protects your grill from destructive weather, and provides a safe space for you to keep patio furniture and cushions.

These units are affordable, made to last, and essentially pay for themselves in a season or two.

On average, grillers who do not winterize or store their grills have to replace them every three years. However, those who seasonally store their grills enjoy five to fifteen years of use from one grill.

The Keter Premier Outdoor Storage Shed with Shelves is one of my favorite vertical sheds for a few reasons.

Real wood looks great, but it requires maintenance. And that’s the beauty of this unit. It looks like a woodshed, but it’s made from heavy-duty plastic resin.

Because of that, it is weather-resistant and won’t crack, peel, or leak.

Maximize storage capacity by adding two shelves to the build-in brackets. And when you’re done, swing the doors shut on their sturdy metal hinges, and lock up.

Why should I get a shed?

A backyard shed can benefit anyone – not just homeowners. Apartment and condo dwellers have even more to gain by purchasing a shed kit simply because they have limited space.

Garages, basements, and attics offer convenient storage, but they often become a disorganized catch-all. And when we need outdoor equipment, we have to tromp through the house to find it.

A shed hides clutter and maximizes space.

Plus, it keeps patios, balconies, and backyards tidy and well organized and allows you to conveniently access your outdoor gear where it belongs: outside.

What to consider when purchasing a shed

There are a few considerations to make when shopping for tool sheds. The most obvious is price and size, but don’t stop there.

The best sheds will enhance the look of your home. Others will have the opposite effect. So before you purchase a DIY shed, consider the features below.

Material

Shed materials range from pressure-treated lumber and aluminum to plastic, canvas, and ripstop polyethylene. These materials are all weather-resistant to some degree, but some are better than others.

Resin

Resin is often used interchangeably with “plastic,” when in truth, it is quite different. Resin is a composite blend that starts as a powder, liquifies during heating, and is then poured into a mold.

This process contributes to the resin’s strength and elasticity. The short answer: Resin sheds are stronger and more elastic than plastic ones, so they will last longer.

Plastic storage sheds

Most “plastic” sheds on the market are actually made from polypropylene. Next to resin, polypropylene may be the closest thing to a “perfect” building material when it comes to sheds.

Why? Because it is tough, won’t crack or dent, is weather-resistant, and some blends of polypropylene can even be painted.

Vinyl storage sheds

Polyvinyl chloride resin, or “vinyl,” is the material used to manufacture most modern home siding. And for good reason.

Vinyl is aesthetically appealing. It just looks good. Plus, it’s weatherproof, cost-efficient, and doesn’t require maintenance.

Steel

Steel is tough, won’t warp, crack, bend, rot, burn, or require maintenance. That’s the upside. The downside is that a steel metal shed is far more expensive than those made from synthetic materials.

They’re also heavier, so once you’ve put your steel shed together, don’t plan on moving it!

Wooden storage sheds

Plastic manufacturers have done a nice job of emulating the look of natural wood, but in my opinion, nothing looks better than real, natural wood.

You can paint wood – and for some, that’s a blessing and a curse. Wood is not impervious to the elements, so it requires maintenance and a new coat of paint every few years.

Climate / Environment

Climate is one of the most important factors to consider when shopping for your own shed.

Snow dwellers should look for a shed with a high snow load rating and a sloped roof peak. If you live in a mild climate, most shed materials will serve your needs.

Those who live in areas with high precipitation will benefit from a shed with a raised floor to keep water where it belongs – away from your expensive lawn tools, BBQ rig, and patio cushions.

Size

I saved the most obvious consideration for last. Before you buy a storage unit, measure the space and compare it with the exterior dimensions of the shed. But don’t stop there.

Also check the width of the door opening to ensure that it is wide enough to accommodate your tools, trash cans, lawnmower, or anything bulky you wish to store.

What is the best outdoor storage shed to buy?

What’s the best outdoor storage shed on the market? That depends on your budget, preferences, climate, space, and the amount of clutter you have.

That said, if I had to choose only one storage unit, it’d be the Keter Manor 4×6 Resin Outdoor Storage Shed.

This unit provides 131 cubic feet of extra space and is made from polypropylene resin and trimmed out with steel. It’s also UV resistant, so it won’t crack or damage in the sun.

The Keter shed is also packed with extras like an interior vent that circulates fresh air and a skylight that offers an abundant natural lighting solution.
