Our Comprehensive Buying Guide

 

If you want to buy the best waterproof outdoor storage box, you should know that you have to consider some essential things to be able to make a good choice. Many products seem good at first glance, but you might be faced with different problems during use and you might have the unpleasant surprise to find water inside or it could even break.

If you are wondering how to build an outdoor storage box, you should know that it is not that complicated. Building a waterproof one, on the other hand, is. This is why the safest way to go is to buy one already made which will take a lot of unwanted weight off your shoulders.

Design 

In terms of design, you should know that there are a few types of products as you have probably seen in our waterproof outdoor storage box reviews and it all depends on the space you have available, the capacity you want it to have and if you want to use it as a seating bench or not.

The ones you can sit on have to be specially made for that because they have to be sturdy enough to hold a lot of pounds without breaking and should be able to hold at least 350 lbs, depending on the model.

Also, the design of your outdoor space is also important because you can choose between different types of boxes such as a wicker outdoor storage box or if you want to make it sunnier or you want monochrome furniture, you can always opt for a white outdoor storage box.

 

Durability

Durability is a very important thing to consider when you have to buy a storage box because you wouldn’t want to invest your money in a product that will break in a few months or will lose its waterproof feature quickly. For best durability, you should choose a heavy duty outdoor storage box. They are a little bit pricier, but they are worth it.

However, a plastic outdoor storage box will also do a great job but you have to be careful about what type of plastic is used. Polyresin is usually a great choice because it provides great waterproof capacity and will not be deteriorated if you leave it in the sun all day.

A wooden outdoor storage box looks great, but it is hard to find one that is also waterproof. There are a lot of storage boxes, however, that mimic wood but are actually made of polyresin or plastic.

Other essential features

As you have probably noticed in every waterproof outdoor storage box review we have made, we have talked about some other important things that make a difference when it comes to quality and functionality. A very important one is security. The best products are the ones that are lockable.

This is important firstly because you might live in an area with raccoons, feral cats, and rats and it is not pleasant to find them sleeping inside your storage box or, even worse, damaging your things.

Portability is also important because you might have to carry it around and the box should be lightweight but also strong enough not to break at the first move. The best storage boxes are also very easy to assemble and have an instruction manual on how you should do that.

 

 

Frequently Asked Questions: 

 

Q: Why should you get a waterproof storage box?

If you have an outdoor space where you like to spend your time during the warm seasons, you probably know that there is a lot of stuff that you would rather put aside than leave out all the time and have your place looking messy. When you are not using them, your cushions need a place to be stored to prevent them from getting wet because of the rain.

However, if you decide to store them in a storage box that is not waterproof, they will most likely get wet. They can even get moldy if you do not immediately take them out. Cushions are easy to clean, but that can be a drag and if water gets to your gardening tools, they could get damaged over time.

The idea is that when you decide to buy a storage box it is because you want to protect your stuff and an outdoor storage box that is not waterproof will not do that.

Q: Can I leave my storage box outside in the winter?

Cheap waterproof outdoor storage boxes do not behave very well in extreme weather conditions and you should avoid the exposure. However, if you have a storage box made of polyresin, you will be able to leave it outside despite the weather conditions. This is, however, if you decide to buy an affordable waterproof outdoor storage box.

In general, the dangers with storage boxes that are left outside during the winter is that they freeze and you will not be able to easily open them. If you have a good one, this will not happen because they are designed so that the water will not stay on the parts that have to be open, such as at the edge of the lid.

If the temperatures drop really low, however, it is best to store your box inside the garage during the winter because some of them are made of materials that can break due to freezing.

 

Q: What size storage box should I get?

Some people have problems deciding if they should buy a small outdoor storage box or a  large outdoor storage box. This is not a real problem as it all depends on 3 things: how much stuff you have to store, how big your outdoor space is, and how much you want to spend.

If you have a lot of things to store, you should definitely go for a large one and you can find a lot of large affordable waterproof outdoor storage boxes on the market that have great quality. If you have a small space, however, you should opt for a medium-sized one.

If your budget does not allow you to buy a large one, you can always go for a smaller box or for a cheap waterproof outdoor storage box of large dimensions. However, this will not be a permanent solution because it will not be durable enough to last for a long period of time.
