Wet rooms have grown from a niche luxury to one of the most popular bathroom choices in the UK. They look stunning, are easy to clean, and work brilliantly in small spaces. But the installation must be done right — waterproofing failures cause serious damage.
What Is a Wet Room?
A wet room is a fully waterproofed bathroom where the shower area is open. The floor is gently sloped towards a drain, and the entire room is tanked to prevent water penetration.
Waterproofing — The Critical Step
Tanking is the make-or-break step. The entire floor and walls must be sealed with a liquid membrane or sheet system. This is not a DIY job — one missed spot and water will find its way through.
Costs
A wet room conversion costs £4,000 to £8,000 including labour and materials. Premium finishes push costs to £10,000+.
