Bathroom Renovation Teddington

GS Renovation renovates bathrooms across Teddington, from compact family bathrooms in bay-fronted Victorian terraces to en-suites in riverside homes near the Thames. We handle the waterproofing, drainage, tiling, heating and fit-out as one job, delivering wet rooms, walk-in showers and space-saving layouts that suit period homes.

In Teddington, 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 Teddington: 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 Teddington 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.

Waterproofing and wet rooms in Teddington

A lasting bathroom starts with proper waterproofing, which matters in Teddington's older terraces where suspended timber floors and solid walls need the right preparation. We tank walls and floors before tiling, so showers and wet rooms are sealed against leaks rather than relying on grout alone. For a level-access wet room we form the falls correctly and set the drainage so water runs where it should, giving a clean, contemporary finish that holds up in daily use.

Drainage and ventilation are easy to overlook and expensive to get wrong, so we route waste properly and fit extraction that clears moisture and protects the plaster and joinery in a TW11 period home. We tile to a high standard, fit underfloor heating where it suits the floor build-up and finish with the sanitaryware and brassware you have chosen. New circuits, and changes to circuits near the bath or shower, are notifiable under Part P, so a registered electrician tests and certifies the wiring as part of the work.

Housing in Teddington

Of the 11,670 homes the valuation list records in Teddington, 40% were built before 1919, 13% between the wars and 47% since 1945; 49% are flats and 51% are houses. Terraced houses make up 27% of homes here, and a terrace bathroom in Teddington vents front, back or up, never into a party wall.

A new Teddington en suite on a Building Notice

Richmond advises a Building Notice only for very simple work, and installing a bathroom is one of its named examples. For a Teddington homeowner adding an en suite, the route is short: submit the notice, wait 48 hours, and work can begin. What the notice does not do is check the design in advance. The questions a Full Plans application would have raised, about the soil pipe route, the fall on the waste and the extract fan, get answered on site instead, which is why we settle them at the survey.

The detail that decides a period en suite is the soil pipe. In the 40% of Teddington homes built before 1919, where the existing stack serves a bathroom at the back of the house, a new en suite in a front bedroom sits a long way from it. A macerator is a fallback, not a plan. Where the run is too long to fall properly, the better answer is a new stack or a different room, and we say which before any tiles are chosen.

Space-saving en-suites in TW11 terraces

Teddington's terraces rarely offer generous bathrooms, so clever planning is what makes a small space work. We reconfigure tight layouts, borrow space from a landing or box room and design en-suites into main bedrooms without the house feeling cramped. A walk-in shower, a wall-hung basin and concealed cistern can rescue a narrow room, and getting the plumbing routes right through solid walls keeps the finish clean and the pipework hidden.

In a closet-wing bathroom or a converted loft, we work with the awkward angles, low walls and existing soil stack that come with a period TW11 property, planning the layout around them rather than fighting them. From the tanking and tiling to the underfloor heating and the final seal, one team delivers the whole bathroom. The result is a practical, watertight room that makes the most of the space a Teddington terrace has to offer.
