Wetroom installation in south London
Fully tanked, level-access wetrooms — designed and built to not leak, with the paperwork to prove it.
A wetroom in south London costs £7,000–£12,000 excluding VAT and takes two to three weeks. The price gap versus a normal bathroom is the structural work: the floor is opened up to form falls to a drain, and the entire room is tanked — and on the suspended timber floors most south London houses have, that structural stage is what decides whether a wetroom leaks.
This is for you if
- You want a walk-in, screen-free shower with no tray and no step
- The household needs level access now or will in the coming years
- A small or awkward room where a tray and enclosure waste the space
- You have seen wetroom horror stories and want it done properly once
- A loft or basement room where a conventional enclosure will not fit
- You want the whole-room tiled look
What's included
- Floor structure opened and rebuilt with formed falls to a linear drain
- Full-room tanking membrane — floor and walls, not just the shower corner
- Flood test before tiling: we prove it holds water before covering it up
- Large-format tiling with movement joints where the substrate needs them
- Concealed shower valve, fixed head and glass where the design wants it
- Underfloor heating option while the floor is already open

Wetrooms — what people ask
How much does a wet room cost?
£7,000 to £12,000 excluding VAT in south London, versus £5,000–£9,000 for a conventional bathroom in the same room. The difference is the floor: forming falls into a suspended timber floor, tanking the whole room and flood-testing before tiling is skilled structural work. Be cautious of wetroom quotes under £6,000 — the usual saving is tanking only the shower corner, which is exactly how wetrooms fail.
Read the full answerDo wet rooms leak?
Properly built ones, no — badly built ones, notoriously. The failure is almost never the membrane product; it is the installation: tanking only part of the room, no flood test, missing movement joints, or falls formed wrong so water pools against a wall. We tank the full room, form falls to the drain before tiling, and flood-test the floor for 24 hours before a single tile goes down. That test is the difference, and we photograph it for your records.
Read the full answerAre wet rooms a good idea in a small bathroom?
Often the best idea. Removing the tray, enclosure and step frees more usable space than anything else you can do in a room under 2m × 2m, and the single tiled surface makes it read bigger. The trade-offs are real though: storage gets wet unless designed in, and you generally want underfloor heating so the floor dries. In a very small room we usually fit a single fixed glass panel to keep towels and paper dry.
Read the full answerDo wet rooms add value to a house?
As a second bathroom or en-suite, yes — a well-built wetroom reads as a premium, future-proof feature and photographs beautifully in listings. As the only bathroom in a family house, it can narrow your buyer pool, because many buyers with young children still want a bath. Our standard advice: convert the en-suite or second bathroom to a wetroom, keep a bath in the family bathroom.
Read the full answerCan you put a wetroom upstairs on a timber floor?
Yes — most of the wetrooms we build in south London are on suspended timber floors upstairs in Victorian and 1930s houses. The floor is opened, joists checked and stiffened where needed, a formed-fall board system installed, then the tanking membrane over it. Timber moves, which is why the membrane system and movement joints matter more upstairs than on a concrete ground floor — and why this is not a job for a general tiler.
