The best plastic sheds offer a range of benefits you don't generally get with other materials — they're typically maintenance free, incredibly durable and easy to assemble. 

The great thing about plastic sheds is that they can be kept looking new with a quick wipe with a wet cloth. They also offer brilliant durability - especially those made from strong polypropylene resin - and in most cases, the panels simply click together which means assembly is pain-free, although larger sheds might prove slightly trickier. 

They come in a range of dimensions, and if you're looking to store garden furniture then it's a good idea to buy the biggest plastic shed you can afford (and that will fit in your garden). But if you're just looking for a secure place to store your cordless drill and other tools, then the best outdoor storage boxes which provide a more compact option would be best.

These are the best plastic sheds you can buy which combine style, space and durability.

How to Choose the Best Plastic Shed

Here are some of the key criteria to consider when choosing the best plastic shed for your home:

Weather-Resistance

Most high-quality plastic sheds are built to withstand the elements, using high-density polyethene (HDPE) or polymerizing vinyl chloride (PVC) vinyl for structural support. The quality of materials is important, so be sure to review your preferred model before buying.

Maintenance

Plastic sheds do not corrode or rust and so have the advantage of being maintenance-free. Every so often you may need to wash off grime or mildew that has collected on the shed.

Design

Most plastic sheds are available in a variety of colours and sizes to complement any garden, and the variations in product features and designs means you won’t be short of inspiration when picking your model. 

Lockable?

Many plastic sheds will have some sort of locking mechanism for extra security.  

How to Prepare a Base for Your Plastic Shed

The most important element of planning where your shed will stand is to make sure it is placed on a flat, concrete or paved base. 

Positioning is pivotal, especially if you're laying on grass - if your shed is placed on an uneven lawn it could warp out of shape over time. If you're laying on grass, then lay a concrete, gravel or wooden foundation first and this will ensure the surface is entirely level.

If you purchase a shed without a base, then you'll need to fix it onto a concrete base, or raised wooden floor. 

Both paved and concrete bases require a sub-base to support the concrete, and while laying a shed base can be done on a DIY basis, it can be quite a technical operation. If you're not hugely experienced then it might be best to ask a professional.
