Are wet rooms suitable for any house?
Most homes can have a wet room, but timber-framed upper floors need additional structural work to create the drainage fall. Ground-floor and concrete-slab rooms are easiest to convert.

Frequently Asked Questions
Do wet rooms cause damp problems?
Not when properly installed. Professional tanking (waterproof membrane) on all walls and floors prevents moisture escape. Always use a certified wet room installer.
Do wet rooms add value?
A well-installed wet room can add value, especially in en-suites. They are particularly valued by buyers looking for accessible or modern bathrooms.
