Garden Shed Floor Kits FAQs

What is a garden shed floor kit?

A garden shed floor kit is a frame designed to create a raised floor base within a compatible shed. It provides a dedicated surface for your storage area and can be used where you don't intend to install the shed on a concrete slab.

How do I know which floor kit fits my shed?

Floor kits are designed for selected Spanbilt shed sizes, so check the compatibility information for the floor kit against your exact shed model and dimensions before ordering. If you're unsure which option you need, contact our team before purchasing.

Do I need a concrete slab if I use a floor kit?

A compatible floor kit can provide an alternative floor base where a concrete slab is not being used. The shed still needs to be installed on a suitable, level site and correctly anchored in accordance with the installation requirements for your shed and floor kit.

What goes on top of the floor frame?

The floor kit provides the supporting frame for the shed floor. Check the product specifications and installation instructions for your selected kit to confirm the flooring material required to complete the floor.

Are floor kits sold separately from the garden shed?

Yes. Floor kits are separate products that can be added when you need a compatible floor base for your Spanbilt garden shed. Make sure you select the correct kit for your shed model before ordering.

Can I add a floor kit to an existing shed?

Compatibility will depend on your existing Spanbilt shed model and how it has been installed. If you're considering adding a floor kit after the shed has already been assembled, contact our team with your shed model and dimensions so we can help confirm the available options.
