Garden Shed Flooring: Australian Guide

A solid floor in your garden shed will make the space more durable and usable and will protect your valuable garden tools and equipment from the elements.

If you’ve decided to erect a new garden shed for all your outdoor tools and equipment, you also want to consider the many options available for your garden shed flooring.

Do you need flooring in your garden shed?

It’s definitely a good idea to put a floor in your garden shed. This will protect your valuable garden tools and equipment from the elements. A floor provides a solid base and is easy to keep clean.

You’ll find that many sheds don’t come with their own floor. This means you need to choose what type of floor you want to install for your shed.

What to consider when choosing flooring for a shed

When choosing the right flooring for your shed, there are a few things to consider.

Probably the most important factor for many people is the cost. For example, a concrete slab is the most expensive option in most cases, but it provides a good solid base that will stand the test of time and whatever the elements throw at it.  

You also want to consider whether the ground is flat, sloping, or uneven. While a concrete slab is a great option, you’ll need to do some excavation if the ground is sloping or uneven to make the base of the shed flat.

In this case, you might be better off opting for a heavy-duty floor kit that allows you to adjust the level of the base to take into account sloping or uneven ground.

This will be more cost-effective and eliminates the need for major excavations while still giving you a flat floor for your shed.

The best shed flooring systems

You basically have 4 major choices when it comes to flooring for your shed. Let’s look at the pros and cons of each one.

Concrete Slab

A concrete slab is a common option that many people select. However, it is also the most expensive and is a permanent solution that you can’t move around if you decide to relocate your shed in the future.

It does need to be installed by professionals and your property will need to have access for a cement mixer to pour the concrete. You also need to ensure that the ground is level first before you start pouring the concrete.

Pavers and Bricks

Installing pavers or bricks as the base for your shed is another popular option. It’s also an easier option if you don’t have access for a cement mixer.

Once again, you’ll want to have a fairly flat base before you lay the pavers.

It’s also difficult to prevent water from coming in during heavy rain unless you use a sealer between the pavers and the base of the shed.

However, this is a great solution if you already have a paved area in your backyard and you plan to install a shed next to this area.

Steel Floor Kit

A steel floor kit will provide a good base for your shed and keep it off the ground. An advantage of this is that it’s not permanent and can be moved around at some time in the future if you want to relocate your shed.

Another advantage of this type of flooring is that it’s durable and will last a lifetime. Plus, steel floor kits are easy to assemble.

Timber Floor

A lot of timber floor kits are made from renewable plantation-grown timber, so these are a good environmentally friendly option. Timber floors are also not permanent and can easily be moved if you need to relocate the shed.

It’s also possible to adjust the floor if you’re going to be sitting your shed on uneven ground to give you a nice flat base. A popular option for timber flooring is yellow tongue because it’s durable and long-wearing.

Cheap garden shed flooring ideas

If you’re on a tight budget, there are some ways that you can use to reduce the cost of the flooring for your shed.

Here are a few options:

  • Lay concrete pavers around the perimeter of your shed for your shed to sit on. Then infill the floor area with gravel. While this won’t give you a solid base, it’s a cheap option.
  • You could also use treated pine sleepers instead of pavers to sit your shed on.
  • If you’re quite handy, you could consider making your own floor from used pallets. You will usually find these for free at Bunnings stores. Bear in mind though, that these may rot eventually.

What is yellow tongue flooring?

Yellow tongue flooring is a manufactured particle board. It is heavy-duty and long-lasting. It also eliminates the gaps between floorboards that can contract and expand with the weather.

The pieces of particle board are connected together in a tongue-and-groove fashion.

Alternatives to yellow tongue flooring

Alternatives to yellow tongue flooring include green and orange tongue flooring and red tongue flooring.

Green tongue flooring is made by Laminex and is a little more moisture-resistant than yellow tongue. You can also get a termite-treated version of this flooring.

Orange tongue flooring is similar to the green tongue but is made by D&R Henderson.

Red tongue flooring is made by Structaflor, the same company that makes the yellow tongue. It is also a little thicker than the yellow tongue (19mm) at 22mm.


Do Bunnings sell garden shed flooring?

Yes, Bunnings sell both timber flooring kits as well as aluminium floor frames and floor panels.

Can you buy garden sheds with a base?

Yes, some smaller garden sheds do come with their own base.
