How much does a wet room cost in the UK?
A wet room costs £5,000 to £15,000 in the UK, typically around £9,000 for the room. Prices reviewed June 2026.
A wet room costs a little more than a standard bathroom because the whole floor is waterproofed (tanked). Size, fittings and whether the floor needs rebuilding for drainage drive the price.

Common questions
Usually a little, because the entire floor is tanked and the drainage is more involved. A compact en-suite wet room can still be done for around £5,000 to £7,500.
Not if they are tanked properly. A correctly waterproofed wet room with the right falls and ventilation is no more prone to damp than a standard bathroom.
