The best outdoor storage box solutions come in a variety of styles and provide a compact alternative to a shed for storing your garden tools, toys and tools.
Whereas the best plastic sheds are suited for larger items such as garden furniture, storage boxes are great for smaller accessories, and they'll most likely double up as a seat, a bench, or even a table unit.
Just because they're smaller though doesn't mean they're flimsy; the best boxes are durable, weather-resistant and impressively constructed to keep your items dry and well ventilated. They'll also have some sort of locking mechanism for extra security.
We've reviewed the best outdoor storage boxes available now, spanning a range of designs and budgets, to help you find the best pick for your garden.

Not only is it weather and water-resistant but it has UV-protected panels to prevent against fading, cracking or peeling. The 568L capacity is generous too (the Lifetime models are available in a range of sizes) - it's brilliant for expanding your patio or garden storage.
Plus, the rigid, double-wall, high-density polyethylene (HDPE) construction makes it strong and durable enough that it can double up as a bench. It's lockable too, comes with handles, and features a spring-hinge lid that won't slam shut, which your fingers will thank you for.

For a stunning contemporary addition to your garden design, this box from ILESTO is a great pick if you're willing to pay more. It looks just as stylish fitted subtlety within your furniture as it does positioned as a standalone feature.
If cost is a factor, then be assured that you get value for money. This box is made with high-quality steel and features a four-layered construction, offering impressive protection for your contents. It also stands up to snow and rain, and is rust-resistant so it should remain in top condition for several years.
One slight drawback is that it's a bit tricky to put together, and in a two-person assembly team you'll likely need at least one DIY enthusiast on hand.

The Rubbermaid Roughneck Mini Deck Box is a great choice when space is at a premium, or for storing smaller items such as tools or garden accessories.
Because of its size, it's understandably one of the easiest of this list to put together, which is made easier courtesy of interlocking panels. It also features double-walled, weather-resistant resin to protect your valuables, although it could benefit from being a little sturdier.
It can also double up as a seat or small outdoor end table.

Keter's second entry on this list is its General Purpose Outdoor Storage City Box, an all-rounder that's easy to assemble and falls under the right side of £50.
This general purpose box bares similarities to the Rubberneck Mini Deck so it's a good fit for balconies and small garden areas without being intrusive. It's available in multiple colour options too, including brown, graphite and dark grey.
It's well-constructed too, with durable, fade-resistant plastic ensuring your items are kept safe and dry.
One drawback however is that while it's lockable, the lock is not included.

How to Choose the Best Outdoor Storage Box
Before you take the plunge and buy your storage box, consider these factors to ensure you get the optimum pick for your home.
Size
Outdoor storage boxes can come in a variety of sizes, therefore it's best to measure the area of the garden you want the box to be positioned in before buying - this is particularly important for tighter spaces.
Capacity
The capacity for storage boxes is measured in litres, which can be difficult to visualise from just an image. If you only need to store smaller items such as furniture cushions and tools then a capacity of between 60-130L should be ample, but for larger items such as fold-up chairs you'll likely need upwards of 500L.
Cost
More smaller outdoor storage boxes can cost as little as £30, but larger metal or wooden units can cost a few hundred pounds.
Weatherproof
Unless you're planning to keep your box under a covering, or it's protected via a roof cover, then make sure you opt for a box that's weather or water-resistant.
