Bathroom Renovation Twickenham

GS Renovation renovates bathrooms and en-suites across Twickenham, fitting new suites, wet rooms and walk-in showers into the Victorian and Edwardian terraces of TW1. We take care of the waterproofing, drainage, tiling and finish so the room performs as well as it looks.

In Twickenham, 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 Twickenham: 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 Twickenham 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 Twickenham

A bathroom only lasts if the waterproofing is right, which matters especially in Twickenham's older terraces with their suspended timber floors. We tank the walls and floor properly before tiling, so wet rooms and walk-in showers stay watertight for the long term rather than leaking into the joists below. Getting the drainage falls and ventilation right at this stage is what prevents damp and rot later.

Falls to the drain, a well-sized waste and proper extraction all get designed in from the start, not bolted on at the end. Where a shower sits over a timber floor, we reinforce and prepare the substrate so the tiling does not crack or move. Underfloor heating is a popular addition in these period bathrooms, warming a room that can otherwise feel cold, and we lay it under the tiled floor as part of the build.

Paperwork and neighbours for a Twickenham bathroom

Richmond names installing a bathroom as one of its examples of very simple work suited to a Building Notice, so the paperwork for a Twickenham bathroom is short. Richmond building control asks for 2 days notice that you intend to commence works. What is inspected is what disappears behind the tiles: the waste falls and the connection to the stack, the extract duct to outside, and any strengthening under a heavy bath or a stone floor. Take dated photographs of each stage before it is boarded, so a query months later can be answered without lifting a floor.

41% of homes in Twickenham are flats, so a new bathroom here may sit directly above somebody else's ceiling. Where it does, the whole floor is tanked, not just the shower area, and every waste and supply joint is pressure or flow tested before it is closed in. A resilient layer under the floor finish cuts footfall and plumbing noise below. If the waste has to run through the ceiling void of the flat underneath, their consent comes first, and an access panel on their side saves opening their ceiling if a joint ever needs attention.

Space-saving bathrooms in Twickenham period homes

Bathrooms in TW1 terraces are often tucked into the rear closet wing or carved out of an awkward corner, so every centimetre counts. We plan layouts that make a small room work, using a walk-in shower instead of a bath, a wall-hung basin and concealed cistern, and clever storage. The aim is a bathroom that feels generous even when the footprint is genuinely tight.

Adding an en-suite to a Victorian bedroom brings its own challenges, mainly getting waste and water to a room that never had plumbing. We work out the pipe runs, boxing them in neatly and keeping the drainage falls correct, so the new en-suite functions properly without spoiling the room. Across Twickenham and nearby Teddington and Kew, this is a common way owners add value to a period house.
