Wet rooms in Teesside
A wet room conversion in Teesside costs £5,000 to £10,000 in 2026. The room is fully tanked, the floor re-formed to fall to a drain, and tiled throughout. Done properly it is the most robust bathroom there is; done cheaply it leaks.
Tanking is the job
The wet room industry has one dirty secret: the visible work (tiles, drain, glass) is easy, and the invisible work (waterproofing) is where failures happen. A proper wet room is tanked with a membrane system across the whole floor and up the walls, with sealed corners and penetrations. Quotes should name the tanking system: "waterproofed" with no method named is a red flag.
The floor matters as much: timber floors need a former (a pre-sloped deck) or a screed fall built in; concrete floors get a screed or a former set in. The fall to the drain is checked with water before tiling, not discovered after.
What it costs
£5,000 to £10,000 depending on room size, drainage route and finish. The drainage is often the variable: a gravity waste to the soil stack is straightforward; a pumped waste adds cost and a maintenance point. The wet room vs shower guide compares the options honestly.
Who it suits
Wet rooms suit three situations: accessibility (level access, no tray to step over), small rooms (no enclosure eating space) and style (the open, spa look). They suit almost every property type, including Teesside's timber-floored terraces, with the right former system.
