Luxury bathroom and wet-room refurbishment in Twickenham. Trusted, professional, 30+ years' hands-on experience.
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. With over 30 years in the Richmond upon Thames borough, we take care of the waterproofing, drainage, tiling and finish so the room performs as well as it looks.

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.
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 one of the most popular ways owners add value to a period house.
Twickenham owners choose GS Renovation for bathrooms because we get the parts you cannot see right, the tanking, the falls, the drainage and the ventilation, as well as the tiling and finish you can. One team fits the whole room, working cleanly in an occupied TW1 home. With 30+ years in the borough, we build period bathrooms that stay watertight and look the part.
George was brilliant. Lovely bloke, very reasonably priced and a perfectionist to boot. He completed our small kitchen renovation with care and great attention to detail. I've already recommended him to others.
Splendid job on our new kitchen refurb, including new flooring, moving the services, installing RSJ and preparing space for new back doors… George was always friendly, communicative and has an excellent attention to detail, ensuring everything is finished to a high standard.
Giorgio is an excellent and intelligent workman, and with very reasonable prices!… He paid a lot of attention to detail that is not common at all, and the final result was immaculate. Highly recommended!
