A wet room is one of the most requested upgrades we install across Bromley, Orpington, Petts Wood, Chislehurst, Sevenoaks and Tonbridge, and the first question is almost always the same: what will it cost? Here are real, current UK market figures so you can budget realistically before booking a consultation.

Written by the team at The Bathroom Project — hands-on bathroom, plumbing and heating specialists serving Bromley, Orpington and across Kent.

What a wet room typically costs

According to Checkatrade's 2026 cost guide, installing a wet room in the UK costs between £4,000 and £12,000, averaging around £8,000 per room, with labour-only rates of roughly £200-£300 a day. A dedicated disabled or accessible wet room averages closer to £5,000 on its own for the accessibility features.

Cost by wet room size

Size is the biggest driver. MyJobQuote's breakdown puts a small wet room (around 2m x 2m) at roughly £4,675, a standard family-sized wet room (2m x 2.5-3m) at around £5,885, and a large or luxury wet room (over 3m x 2.5m) with a full suite, underfloor heating and higher-spec finishes at around £8,360.

What pushes the price up

Structural or drainage work, moving plumbing, underfloor heating, premium tiling and larger room sizes all add cost. Waterproofing (tanking) alone typically runs £30-£40 per square metre according to Beams' UK wet room cost guide, and is not a step we ever skip, because it's what stops a wet room leaking into the floor below.
