Shed Base Reviews | How to Buy and the 6 Best Shed Bases Compared

A garden shed gives you a place to store your tools and equipment, but having a solid base beneath can significantly increase the lifespan of your shed. Standing between the shed and the ground, the base provides stability and protects your shed from water, dampness and rot, especially for wooden sheds. A shed erected on bare ground is also likely to become unstable over time due to soil movement and that makes having a base almost an indispensable thing, with some bases even designed to adjust in height depending on whether the ground is level or uneven.

So what is the best shed base available on the market? Truth is, it comes down to your individual needs such as the size of shed, the type of shed and whether it’s plastic or wooden, as well as product features like waterproofness, ease of assembly and how versatile it is. We’ve reviewed some of the top-rated shed bases in the UK with the goal of helping you buy a model that suits your needs.

After comparing our six finalists, we concluded that the ECO Deck Garden Shed base is the winner of our “Best Pick”. Made from recycled plastic, this model can support tonnes of weight for years. The product is UV stable and comes with a 25-year warranty and is probably the easiest to set up with minimal effort. Find out more from the in-depth reviews section and feel free to engage with us afterward.


A great choice for most large sheds, this base is simple and quick to install thanks to connectors that seamlessly lock in position. The model is also available in different sizes so you can choose anything south or north of this 8 x 6 base. It’s manufactured from recycled British materials with heavy-duty membrane and sturdy plastic grids, making it an environmentally-conscious option. This premium quality shed base comes with a 25-year warranty so rest assured you’ll be investing your hard-earned money in the right place.


QuickJack Shed Base System
Unlike most shed bases with plastic grids, this comes with metal jacks that you plant into the ground and fix a frame of your choice onto them. The jacks are adjustable and suitable for surfaces with up to 8 inches of slope. Installing them doesn’t require any tedious preparation or special equipment either. This product can also be fixed on a solid floor. Better still, the whole thing is covered by a 10-year warranty for peace of mind, though many find it an expensive option especially because it doesn’t come with a frame.

Buyer’s Guide

How large should your shed base be?

Ideally, it should be almost the same size as the floor of your shed. However, there are those who like to build their bases slightly larger than the shed’s floor. This helps to keep weeds and grass away from the shed walls. It also allows for cleaner access and space to empty out tools and equipment onto a hard-standing area. On the downside, it may foster dampness by allowing raindrops to bounce off the projecting section of the base and up onto the side panels.

What type of shed base should you install?

Sheds were traditionally built on concrete bases or placed on top of a paved area. The only problem with these methods is that they are time-consuming, labour-intensive and cost so much more money. The alternative to this heavy work is to install a plastic or wooden shed base.

Plastic shed bases

Plastic shed bases are usually made from recycled plastic, which is also great for the environment. They are ultra-lightweight, allowing you to install them without even an extra hand. A plastic shed base is usually made of interlocking tiles that look like puzzle pieces and these pieces are designed to fit together smoothly for easy and quick assembly. You will need to fill the spaces in between with a filler material such as pea gravel or sand.

Even with gravel infill, a plastic shed base allows airflow to ensure that the bottom of your shed won’t rot or corrode. The plastic base itself is not susceptible to rot and won’t crack under the stress of the load standing on it. The plastic is also usually UV stabilised to prevent stiffening or becoming brittle from exposure to the sun as regular plastics do.

Plastic shed bases also sit directly on the ground and they don’t have protruding sections where rain may hit and splash onto the walls of the shed. This ensures that your wooden shed won’t get wet.

That said, a plastic base is a great fuss-free, cost-effective and long-term option for creating a solid foundation for your shed or any other garden structure. Whether your shed is plastic, wood or metal, you can count on a plastic base for years.

Wooden shed bases

Most people use wooden bases for their sheds. They are very easy to construct because all you need to do is to cut the timber to size and screw them together. Whilst you can lay your wooden shed base on bare ground, it is not such a good idea. Contact with the wet ground can cause the timber to rot faster than you can imagine. Of course, you can lay pavers before the wooden base and protect it from moisture damage but this will cost a lot more money and time.

If you want to go for a wooden shed base, make sure it’s made of pressure-treated timber. This trick helps the wood to resist decay and last for many years. You will find that most pressure-treated wooden models are warranted for 10-20 years, but that’s because of the treatment.

Another modern technology method that works with wooden shed bases is the use of QuickJacks. These are galvanised metal jack systems designed to attach onto the bottom of a wooden frame and then drilled into the ground to a given depth. They are a doodle to fit and extremely long-lasting. Most importantly, they are independently adjustable allowing you to set a level base, even on sloping grounds.

Even after your shed has been assembled, QuickJacks can be adjusted up or down, making them perfect for unstable areas that may be prone to sinking or for adding new building properties. Because they are mainly used in conjunction with a wooden frame, QuickJacks are ideal for wooden structures such as sheds, log cabins and summerhouses. They can also be compatible with metal or plastic buildings if you build a decked surface on top of the frame.

Basically, the choice is between a plastic base shed and a wooden shed base. Having addressed their pros and cons, let’s look at the options available for you.
