What is the smallest space you can fit an en-suite? Generally, the minimum space that you’ll need for an en-suite that is fitted with a basin, toilet and shower is approximately 0.8m by 1.8m. With this size space, remember that the bathroom door will need to open outwards.

The minimum space you’ll require for an ensuite bathroom is usually 0.8m by 1.8m – which is enough floor space for a shower, basin, and toilet. A bigger space can give you more options for your ensuite, meaning you may be able to include a bath and a shower, or perhaps a double basin vanity unit.

A half bath ensuite is the smallest ensuite size. It will just barely fit a toilet and basin, or a shower and basin. They are usually attached to very small bedrooms, so every inch of space is critical.

What Is The Smallest Size An Ensuite Can be? No government rule or regulation determines a minimum size for any bathroom. That means you can create an ensuite in a very small space. For many homeowners, the perk of having a private shower and WC rather than sharing with the kids makes a small ensuite preferable over none.
