What To Look For in a Waterproof Garden Storage Boxes

A lack of storage both in the home and garden is an issue many homeowners face. A waterproof storage box is a great way to make the most of your outdoor space. These can be used to store blankets, cushions, kids’ toys and garden accessories when they’re not in use. 

You’d be forgiven for thinking that waterproof storage boxes aren’t the most aesthetically pleasing of storage solutions, but I’ve put together my top picks with both the design and practicality in mind. We’re saying goodbye to bulky and garish plastic boxes and hello to wood-effect storage solutions, designed to blend in with your existing garden furniture and decor. 

The best waterproof storage box will have enough space for your needs, be easy to put together and, of course, be fully waterproof. I’ve gone with the Keter Marvel+ Box as my top recommendation thanks to its spacious 270L capacity and smart panelled design.

Keter Marvel+ Waterproof Garden Storage Box Review

The Keter Marvel+ Waterproof Garden Storage Box is a spacious waterproof box with a practical and stylish design. This box comes in a graphite grey finish and it has an attractive wood panel effect. While many storage boxes have a very basic design, this box is stylish and won’t clash with the rest of your garden decor.

With a roomy 270L capacity and a simple opening mechanism, this box is both practical and convenient. The lid simply lifts up using the integrated handle, while the built in handles at either side can be used to transport the box.

There’s also a set of wheels provided, so the box can easily be pulled across hard ground. It should be noted however, that the box will still need to be lifted at one side to move it.

Durable, weatherproof, maintenance free and UV resistant, this box is designed to last. It’s perfect for storing garden cushions, blankets or even small tools, while it’s strong enough for a lightweight adult to sit on if needed. Its versatility and durability makes it great value for money.

If you’re looking for a long lasting and weather resistant box, the Keter Marvel+ Garden Storage Box is my top recommendation.

Pros

  • Reasonably solid once assembled - lid is reinforced so doesn’t ‘sink’ if you sit on it
  • Wood panelled effect is more stylish than a plain plastic box
  • Very spacious with 270L of internal space
  • Fully waterproof even in torrential rain

Cons

  • Although instructions are clear, a lot of care needs to be taken during assembly to get all the pieces in the right place
  • There’s just one set of wheels provided so the box needs to be lifted at one end
  • Although it won’t fade in the sun, harsh sunlight may weaken it overtime

Charles Bentley Waterproof Storage Box Review

The Charles Bentley Waterproof Storage Box is another large capacity storage box well deserving of its place on this list.

This storage box boasts a butterfly lid which is very easy to open. As opposed to lifting the whole lid at once, the lid splits in half and lifts at either side. This is a welcome feature for those with limited strength or mobility, who may struggle to lift the full lid.

As I’ve already mentioned, this box has a large capacity of 322L. It’s suitable for storing cushions, BBQ equipment, tools and blankets, while it’s fully weather resistant. It can be assembled in just 5 minutes.

The only downside practicality-wise is that unlike others on the market with a flat lid, this can’t really be used as additional seating. It’s also not the sturdiest on the market, so best installed in a sheltered area.

However, this is reflected in the price and, for such a large box, this unit is great value for money.

Pros

  • Unique butterfly lid opening is suitable for those with limited strength or mobility
  • Easy to assemble - clicks together in around 5 minutes
  • Very spacious interior with a 322L capacity

Cons

  • Rain tends to pool in the area where the two lids meet
  • Design isn’t as stylish as others on the market - looks very plastic
  • Not the sturdiest on the market so best installed in a sheltered area and wouldn’t be particularly secure

Lifetime Waterproof Garden Storage Box Review

For capacity alone, the Lifetime Waterproof Garden Storage Box simply cannot be beaten. This box has an enormous 439L capacity which makes it suitable for a range of garden accessories, including tools and even small items of machinery.

As this storage box is very large, it’s important that the design isn’t too obtrusive. Lifetime have fully thought this through, producing a box with an attractive desert sand finish and aesthetic wood panelling. It won’t look out of place in your garden, and it can be used as extra seating if needed.

More practical design features include a hinged lid that won’t spring open or slam shut, as well as moulded handles so you can easily move it to the desired location.

Weather-resistant wise, this box ticks all the boxes. It’s made from rigid dual-wall high-density polyethylene, and it’s very strong. The weather and water resistant seal protects the contents even in torrential rain.

A small word of warning, this box is very difficult to assemble. Lots of extra tools are needed, and it takes a long time even with an extra pair of hands. However, for its large capacity and great design, this box remains a great value for money option for those after an outdoor storage solution.

Pros

  • Strong and sturdy unit that can support two people sitting on it
  • Hydraulic lid hinges are reliable and great for those with limited mobility
  • Huge amount of internal space at almost 440L
  • Metal padlock fittings are more durable than the plastic fittings seen on other models

Cons

  • Some of the pre-drilled holes in the metal support bar don’t line up with the holes in the plastic - new holes may need to be drilled
  • Very difficult to assemble - instructions are unclear and a lot of extra tools are needed

Keter City Waterproof Garden Storage Box Review

The Keter City Waterproof Garden Storage Box is for those who don’t have a huge amount of space in their garden. This box has a relatively compact footprint, measuring just 57.8 x 44cm. At 55cm tall, it still benefits from a 113L capacity.

This box has a neat design, with a number of practical as well as aesthetic features. The wood effect panelling is very attractive, while the handles can be used to move the box to the right location. The lid lifts easily, and it can be locked if needed, although you’ll need to purchase a lock separately.

Those of you with little DIY experience can breathe a sigh of relief when I tell you that this box is very easy to assemble. While the small size helps with this, the reality is that it’s designed very well. Each piece simply clicks together and assembly takes just a few minutes.

Finally, this storage box is fully waterproof. It’s made from durable, weather resistant and maintenance-free plastic. The only downside is it’s very lightweight and, when not filled with heavy items, may not stand up well to strong winds.

This box marks fantastic value for money, with a noticeable difference in price between this and larger boxes on the market. If you’re looking for a neat and compact storage box, this Keter City Storage Box is a great option.

Pros

  • A good size for smaller outdoor spaces - small footprint at 57.8 x 44cm yet it still boasts a roomy 113L capacity
  • Very easy to assemble - parts click into place and assembly takes just a few minutes
  • Fully waterproof - contents will stay dry even under heavy rainfall
  • Although not intended to be used as a seat, it is strong enough for someone lightweight to sit on or it doubles up as a side table

Cons

  • Should be kept in a sheltered area as it’s very lightweight and may become damaged by wind
  • Lacks the metal reinforcements of other storage boxes so may not last as long

Keter Borneo Waterproof Garden Storage Box Review

Fans of rattan furniture will love the Keter Borneo Waterproof Garden Storage Box. This storage box has a decorative wicker-style finish that pairs well with most garden furniture. It’s made from durable, weather-resistant plastic that won’t fade in strong sunlight.

This box is highly practical thanks to its spacious 416L interior and piston assisted lid. It’s very easy to access the contents of the box; the lid won’t slam shut if you drop it. This box can be used to store a whole range of garden accessories or tools, and it even doubles up as a seating area for two adults.

Unlike some of its competitors, this box is extremely easy to assemble. It can be put together in just 10 minutes and it weighs just over 14kgs. It’s easy enough for two people to carry, but it’s not so light that it’s at risk of being blown around by strong winds.

Marking great value for money given the stylish design and spacious interior, the Keter Borneo Outdoor Storage Box is well worth considering if you’re in need of a lot of storage.

Pros

  • More stylish than others on the market - decorative wicker-style finish
  • Large 416L capacity suitable for storing garden cushions, blankets and heavier items
  • Piston assisted lid makes it easier and safer to open and close
  • Fully weather resistant - heavy enough to withstand strong winds and won’t fade in harsh sunlight
  • Very easy to assemble in around 10 minutes

Cons

  • Water pools in the edge of the lid and can drip down into the box when the lid is open if you’re not careful
  • After long term exposure to freezing temperatures, the plastic may become brittle and crack

How to Choose The Best Waterproof Garden Storage Box

A lack of storage is one of the biggest problems homeowners face, and this is the case both inside the home and in the garden.

This can be even more of an issue for those with small gardens, but really applies across the board.

The waterproof garden storage box is a great way to make the most of every square metre of your garden. These boxes come available in a range of sizes and can be used to store cushions, blankets, and even tools and machinery if you’ve not got a shed or garage!

Here are a few things to consider when it comes to buying the best waterproof garden storage box for your needs.

Choosing the Best Material

The initial choice you’ll have to make when deciding on which garden storage box is best for you is the material. There are two main materials to choose from; plastic resin or wood.

All the boxes I’ve recommended are made from plastic, which boasts a number of advantages over wood.

  • It often comes in a style that is made to resemble wood – style for a fraction of the price!
  • It is much more affordable than wood and suits most budgets
  • It’s usually very lightweight so easy to move from place to place
  • It’s maintenance-free, unlike wood which will need to be treated every so often
  • It’s weatherproof, waterproof and difficult to damage
  • Some more expensive boxes may have UV protection so won’t fade if exposed to strong sunlight

Wood is a more traditional choice but tends to lack some of the more practical aspects of plastic.

  • It offers a timeless and classic design
  • Needs to be treated yearly to ensure the wood doesn’t rot
  • Storage compartment may not be fully watertight (hence why plastic is usually used for waterproof boxes)
  • Will start to show weather damage over the years
  • Can be very heavy

Design

Plastic storage boxes generally have a simple design, but they come available in a range of finishes and colours. The more expensive boxes can double up as benches or coffee tables, while cheaper boxes will be smaller and likely not last as long.

Things to look out for design-wise include easy access (so either a removable lid or a gas lifted lid) and ease of movement. Most storage boxes have wheels and handles so they can be relocated with minimal fuss. Elevated feet will help keep the contents dry, but this isn’t completely necessary if the box is fully waterproof.

Those with an assisted lid are easier for those with limited mobility or strength to use, and there’s no concerns that a child (or adult!) will accidentally trap their fingers as the box shuts.

Storage Size and Functionality

Of course, the size of the box will also be extremely important.

You’ll need to look at the specifications for the box you want to buy, and check the size of the storage compartment carefully. This is normally measured in litres, and it can be hard to work out how much storage there is just by looking at a picture of the box online.

Larger boxes will have up to 500L of space, while smaller ones may have under 200L.

Consider what items you would like to pack away in there, for example: children’s toys, BBQ utensils, gardening tools or cushions.

Some storage boxes also double up as extra seating. While dual-purpose storage boxes are available, you should be able to find some plastic boxes that can seat one or even two adults.

Weatherproofing

It’s important that the storage compartment is fully watertight. The very best waterproof storage boxes will not only be made from waterproof materials, they’ll also have a watertight seal.

If your box is going to be stored outside, it’s important that it’s resistant to all weather conditions, not just rain. Be careful with very lightweight plastic boxes because, if left empty, they may blow away in the wind! If your box is especially small, I recommend either weighing it down with heavy items inside, or keeping it in a more sheltered area.

The sun can also cause a lot of damage. A UV-resistant box is best if it’s going to be kept in a sunny location. Worst case, the sun can make your plastic box very brittle and prone to cracking. A less-dramatic but still disappointing effect is that the colour may start to fade over time.

Waterproof Garden Storage Box FAQs

Can I keep cushions in my storage box?

Provided your box is completely watertight, you should be able to store cushions and blankets inside it. Even if you think your box is fully watertight, I recommend not leaving textile items inside it for long periods of time as they may still get damp.

It’s also best to allow any textile items to fully dry before putting them inside the box.

How big a storage box should I buy?

This depends on the amount of space you have available, as well as the items you are needing to store in it.

If you have a smaller garden or wish to tuck your storage box away in a corner, there are very compact options available. Remember that storage boxes do tend to look bigger online than they do in real life! 100-200L will fill up very quickly.

How do you keep moisture out of storage bins?

Even if your storage box is watertight, you may still find it becomes damp over time.

To keep moisture out, you should ensure that all items are both dry and clean before putting them away. Anything with even a hint of moisture may become mouldy, while wooden and metal items can rot or rust.

If you still notice your storage bin getting damp, I recommend using a homemade dehumidifier to absorb any excess. One of the most effective ways is to sprinkle baking soda around the box. This should help get rid of any damp.
