What moves the price

  • Tanking — the whole floor and lower walls are waterproofed, which is the most important part of a wet room
  • Floor gradient and drainage — creating a fall to a linear or point drain may mean lowering the floor
  • Floor construction — timber floors need extra strengthening and a former tray compared with concrete
  • Tiles and fittings — anti-slip porcelain, glass screens and thermostatic showers vary widely in price
  • Underfloor heating — warms the wet room floor and helps it dry, but adds an electrician's work
  • Size of the room — a small en-suite wet room costs less than a large family bathroom

How to pay less

  • Keep the shower drain near the existing waste so the floor gradient is simple to form
  • Choose standard anti-slip porcelain rather than natural stone for the wet room floor
  • Ask about a Disabled Facilities Grant from the council if the wet room is needed for access

Before you book

  • New circuits and underfloor heating in a wet room should be done by a Part P registered electrician
  • Ask how the wet room installer tests the tanking before tiling, and what guarantee covers leaks
  • On timber floors, check the joists can take the weight and the drop for the drain
  • Good ventilation matters in a wet room, so check the extractor fan suits the size of the room

Wet Room Installer cost: questions people ask

£5,000–£15,000 per room, about £8,000 typical. A small en-suite wet room costs least; a large room with stone tiles and underfloor heating costs the most.

One to two weeks for most rooms, as the tanking must be tested and dry before tiling.

Possibly. The Disabled Facilities Grant from your local council can pay for adaptations such as a level-access wet room for disabled people, subject to a means test.

Not if it is tanked properly. Most leaks come from poor tanking or a badly formed drain, so check the installer's experience and guarantee.

Moving walls, electrics beyond the room, a better extractor and redecorating other rooms are often extra.
