Wet room and walk-in shower installation in London

A wet room or a walk-in shower looks like a simple job from the outside — no tray, no enclosure, just a floor that drains. What actually makes it work is underneath: waterproof tanking taken up the walls, a floor built to a fall towards the drain, and a gully sized for the flow. Get that wrong and the leak shows up two floors down, long after the tiler has gone.

Before you call

Worth knowing first

Some of this may save you a callout entirely. We would rather tell you than not.

The waterproofing is the job, the tiling is finishing

Tanking membrane, taken properly up the walls and sealed around every pipe penetration, is what actually stops water getting into the floor and the flat below. Tiling on top of poor tanking still leaks — it just takes longer to show.

A wet room needs a joist depth check first, in a flat especially

Forming a fall to the drain usually means dropping the floor level, which needs depth in the joists or slab to do properly. In a top-floor flat with limited build-up, that is the first thing worth checking, not the last.

Flats need the freeholder involved

A wet room floor build-up and drainage change in a leasehold flat often needs the freeholder’s consent, and sometimes affects the flat below’s ceiling void. Worth raising early rather than after the floor is already open.

A walk-in shower is not automatically a wet room

A walk-in shower with a tray and glass panel gets most of the look without lowering the floor, and is a smaller job. A full wet room is the right answer for genuine level access; a walk-in tray is often the right answer for everyone else.

Questions

Common questions

Do I need planning permission or building control sign-off?

Not planning permission for a like-for-like bathroom. Building regulations do apply to the waterproofing and drainage, and we work to them as standard.

Can a wet room go in a flat, not just a house?

Yes, though floor depth and the freeholder’s consent are worth checking early — both can affect what is possible before you commit to a design.

How long does a full wet room take?

Typically one to two weeks depending on the extent of floor forming and finishing, longer than a standard bathroom refit because of the drying time tanking needs at each stage.

Will it smell or let damp through eventually?

Not if the tanking and falls are done properly and given time to cure before tiling. Rushed drying time is the most common cause of an eventual failure, not the wet room concept itself.
