Bathroom Renovation Brixton

GS Renovation creates bathrooms, en-suites and wet rooms across Brixton, working within the tight footprints of SW2's flats and its Victorian and Edwardian terraces. We handle the waterproofing, drainage, tiling, heating and electrics as one job, turning awkward closet-wing bathrooms and unused corners into calm, hard-wearing spaces built to last.

In Brixton, 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 Brixton: 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 Brixton 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 tanking in Brixton

In Brixton's terraced houses, many bathrooms sit in the rear closet wing, a single storey back addition where the floor and walls need proper waterproofing before anything else. We tank the room with a fully bonded membrane, form the falls to the drain and only then tile, so water goes where it should and not into the structure. For a walk-in shower or full wet room, this tanking is the difference between a bathroom that lasts and one that leaks.

Older SW2 terraces bring drainage and ventilation challenges, and we plan for both. Moving a soil connection or adding a shower waste often means reworking pipework in a back addition, which we set out to fall correctly. Good extraction is essential in these solid-walled rooms to control condensation, so we fit proper ventilation and, where the electrics are involved, have the notifiable work certified by a registered electrician. Underfloor heating keeps a tiled period bathroom warm underfoot.

Housing in Brixton

Brixton's housing, as the Council Tax list records it, is about 21,700 homes: 20% houses, 80% flats, with 47% pre-1919, 8% interwar and 44% built since 1945. Most homes here are flats, and a bathroom in a flat in Brixton sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.

Joists and stacks under a bathroom in a Brixton conversion

In Brixton, 47% of homes were built before 1919 and 80% are flats, so a bathroom here can easily sit on old timber joists above someone else's ceiling. A century of plumbers has often been through those joists, notching them for pipes, and a notch near the middle of a span weakens a joist far more than one near the wall. Before tanking, we lift the boards along the bath and shower positions and look. Where joists have been cut too deeply, the structural engineer we appoint specifies strengthening, and it goes in before the new deck, not after a crack appears below.

The shared stack sets the layout. In a converted house one soil stack often serves more than one flat, and a new WC or shower has to reach it with a steady fall between joists rather than across them. The stack also belongs to the building, so connecting a new branch is normally a matter for the freeholder's consent. We agree the connection point and pipe route first, then plan the room around them, which is why a Brixton bathroom design starts under the floor rather than with the tiles.

Space-saving en-suites across Brixton

Brixton's terraces rarely offer spare square footage, so creating an en-suite usually means borrowing space from a bedroom, a landing or the box room over the stairs. We plan these tight layouts carefully, choosing a compact shower, a wall-hung basin and concealed cistern to free up floor space and light. Careful positioning of the drainage and a slim-profile design mean even a small SW2 bedroom can gain a genuinely usable en-suite.

A family bathroom in a Brixton terrace works hardest when the layout is thought through. We make the most of alcoves and the space beneath a sloping closet-wing roof, choose sanitaryware scaled to the room and use large-format tiles or clever storage to make it feel bigger. From the tanking and pipework to the tiling, heating and lighting, one GS Renovation team fits the whole bathroom, working cleanly in your occupied home.
