Waterproofing first. Everything else is finishing.
Bathroom Renovations in London
Every failed bathroom fails in the same place — behind the tiles, where nobody looked.
A bathroom is the most technically demanding small room in a house. It combines water under pressure, water by gravity, electricity, ventilation and heat in about four square metres, and the consequences of getting any of it slightly wrong appear on the ceiling of the room below, usually eighteen months later.
We build bathrooms from the substrate out. Tanking membranes lapped and sealed properly, falls formed before tiling rather than hoped for afterwards, concealed cisterns and valves left accessible, and extraction that actually moves the air it is rated for. The tiles and the brassware are the part you choose; the rest is the part that decides whether you ever think about the room again.
Options
Types of bathroom project
From a straightforward replacement to forming a new room where there was not one.
-
01Family bathroom replacement
2–3 weeksStrip back to substrate, re-run first fix, tank, tile, fit and finish in the same footprint. Typically two to three weeks.
-
02Level-access wet room
TechnicalFloor structure lowered or a former installed, linear drain, full tanking and a fully tiled enclosure. Requires attention to joist depth and drainage fall.
-
03En-suite formation
New roomA new bathroom created in a bedroom, landing or loft. Soil connection, pumped waste where gravity will not reach, acoustic insulation and a door that does not open onto the WC.
-
04Downstairs WC
CompactUnder-stair or hallway cloakroom, usually needing a macerator or a new gravity run and always needing mechanical ventilation.
-
05Loft bathroom
With conversionBuilt as part of a conversion, with pressure resolved by an unvented cylinder or a pump and the soil stack extended correctly through the roof.
What you get
How we approach it
Full tanking, not a bead of silicone
Tanking membrane to all wet zones, lapped into the tray or former and sealed at every corner and pipe penetration before a single tile goes up.
Falls formed, then tiled
Wet room floors are set to fall in the screed. Trying to create a fall with tile adhesive is how you end up with standing water in a corner.
Access designed in
Concealed cisterns, shower valves and isolation points reachable through a panel or a removable tile — so a future repair is an hour, not a demolition.
Real extraction
Ducted to outside with the correct rating and run length, on a timer overrun, with make-up air. Not a fan spinning into a loft void.
Before you start
The things that go wrong
The items below are where projects most often stall. We raise them at survey stage, not halfway through.
Water pressure
A gravity-fed system will not run a large rainfall head. Either the cylinder changes to unvented or a pump goes in — decide before the shower is chosen, not after it disappoints.
Joist notching
Waste and pipe runs cut carelessly through joists weaken a floor. Notches and holes have permitted zones and sizes, and we work within them.
Electrical zones
Part P zones govern what fitting can go where in relation to the bath and shower. Everything is RCD protected and certified.
Substrate movement
Tiling large-format porcelain onto a springy timber floor cracks grout within a year. The deck gets stiffened first.

Bathroom Renovations — your questions answered
The questions we are asked most often about this service. If yours is not here, call us — we would rather answer it now than after you have committed.
Two to three weeks for a replacement in the same position, three to four for a wet room or a reconfigured layout. Tanking and screed need curing time that cannot sensibly be rushed.
Usually. It depends on the distance and fall available to the soil stack. Where gravity will not reach, a concealed macerator or a shallow-gradient solution is designed in and left accessible.
It can be excellent, but it needs floor depth for the fall and a properly formed drain. On a suspended timber floor with shallow joists, a low-profile tray set flush is often the better engineering answer.
We can, at trade rates, or fit what you have chosen. Either way we check availability and lead times before the programme is set, because a missing item stops a bathroom dead.
