In Hammersmith and Fulham, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hammersmith and Fulham: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Hammersmith and Fulham home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Wet rooms and waterproofing in Hammersmith and Fulham

A wet room or walk-in shower only works if it is properly tanked, and in the borough's older terraces that matters even more where timber floors and lath-and-plaster walls sit beneath the tiles. We tank the walls and floor with a full waterproofing membrane, form the falls correctly to the drain, and only then tile, so water is managed rather than left to find its way into the structure below.

Drainage and ventilation get the same care. Connecting a new shower or relocated WC into the existing soil stack in a W12 or SW6 terrace needs the right falls and an extract fan to control the moisture these enclosed rooms generate. We plan the pipework, the ventilation and the tanking together, so the finished room stays dry, fresh and free of the damp problems that plague poorly done bathrooms.

Housing in Hammersmith and Fulham

Roughly 95,080 dwellings sit on the valuation list for Hammersmith and Fulham. 23% are houses and 77% flats, and by age 56% predate 1919, 9% are interwar and 34% post-war. Since most homes here are flats, a bathroom in a flat in Hammersmith and Fulham sits over a neighbour's ceiling, so tanking comes first.

Bathroom drainage inspections and newer floors in Hammersmith and Fulham

Where a Hammersmith and Fulham bathroom moves and the new drainage is notified to building control, the drainage inspection needs 5 days' notice, not the 1 day most visits need. That changes the order of the job. The new soil and waste runs are fitted and tested with the floor still open, and the floor stays open until the inspection has happened. Booking that visit the week before the plumber finishes keeps the tiler's start date safe. Leaving it until the boards are ready to go down usually costs most of a week with a bathroom out of use.

The other surprise is in newer flats. 16% of homes in the borough were built in 2000 or later, and bathrooms in blocks of that age can sit on an acoustic floor build-up of resilient layers, battens or a floating screed that stops footsteps reaching the flat below. Breaking out tiles without knowing it is there can damage the layer that keeps the building compliant for sound. We ask the managing agent for the floor specification before strip-out, and rebuild that layer as it was if any of it has to be disturbed.

Space-saving bathrooms in Hammersmith and Fulham terraces

Bathrooms in these period houses are often carved from a former closet wing or a slice of a bedroom, so space is tight. We design layouts that make the most of every inch, using wall-hung units, compact walk-in enclosures and clever storage in the awkward corners created by the terrace's original plan, common on the streets around Bishops Park and Parsons Green.

Adding an en-suite to a main bedroom or squeezing a shower room under the stairs is popular across Fulham and Shepherd's Bush, and we route the plumbing and drainage discreetly to suit. Underfloor heating frees up wall space and warms cold tiled floors, tiling is chosen to suit the age of the house, and the electrics are certified by a registered electrician under Part P.

Cutting joists safely for new waste runs

Moving a WC or a bath in a Victorian terrace usually means getting a large waste pipe through the floor structure, and that is where bathrooms quietly damage houses. There are limits on where a joist may be notched or drilled: notches near the middle of a span, or a hole drilled low in the section, take strength out of exactly the place the joist needs it. A 110mm soil pipe will not lawfully pass through most joists at all.

So we plan the drainage before the sanitaryware is chosen. Where the run cannot follow the joists, the answer is a raised plinth, a boxed duct at the wall, or a layout that keeps the WC close enough to the stack that no macerator is needed. If a joist has already been butchered by a previous installation, we double it up or replace it. In a W6 terrace with lath and plaster ceilings below, that is worth doing properly.
