Luxury bathroom and wet-room refurbishment in Surbiton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Surbiton, making the most of the tight spaces in KT6's Victorian and Edwardian terraces. With more than 30 years of experience in South West London, we handle waterproofing, drainage, tiling, heating and every fixture, so a dated period bathroom becomes a properly built, watertight room.

Many Surbiton bathrooms sit in the old rear closet wing or a first-floor return, where the floors are timber and the walls are solid brick. Getting the waterproofing right on these surfaces matters, so we tank the wet areas fully before any tile goes on, rather than relying on grout to keep water out. For walk-in showers and wet rooms we form a properly graded fall to the drain and seal every junction, which is what stops leaks reaching the rooms below.
Ventilation and drainage need real thought in these older houses, where soil pipes and joist runs were never planned for modern bathrooms. We set out extraction to clear moisture and prevent damp, and route new waste so it falls correctly to the existing stack. On the timber floors typical of KT6 terraces we make sure the structure can carry a stone or large-format tile before we commit to the finish.
Adding an en-suite to a Surbiton terrace usually means carving space from a bedroom or borrowing from the landing, so every millimetre counts. We plan compact layouts around wall-hung basins and toilets, sliding or pivot shower doors and concealed cisterns, keeping the room usable without feeling cramped. Underfloor heating frees the wall space a radiator would take and warms tiled floors that otherwise feel cold underfoot in a period house.
In the main family bathroom we work with the awkward proportions these terraces throw up, sloping ceilings under the roof, chimney breasts and narrow returns, turning them into recessed storage or a neat shower enclosure. Tiling, sanitaryware, heating and lighting are all fitted by the same team to a proper finish. Across KT6 we make small period bathrooms feel considered and generous rather than merely squeezed in.
Surbiton homeowners choose GS Renovation because we build bathrooms that stay watertight, tanking properly, grading falls correctly and sorting drainage and ventilation in older houses where none of it is straightforward. One team handles the plumbing, tiling, heating and finish, and the electrics are certified under building regulations. More than 30 years of local work stands behind every room.
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!
