Luxury bathroom and wet-room refurbishment in Clapham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Clapham, working within the tight footprints of SW4's Victorian and Edwardian terraces. With over 30 years in South London, we handle waterproofing, drainage, tiling and heating in-house, turning cramped or dated rooms near the Common into properly finished, hard-wearing spaces.

Bathrooms in older Clapham terraces are frequently squeezed into the rear closet wing or a boxed-in landing, where a hidden leak can quietly damage the period fabric below. We tank and waterproof properly before tiling, so wet rooms and walk-in showers stay watertight for the long term rather than failing a few years in and soaking the joists.
Getting the services right matters as much as the finish. We upgrade drainage to fall correctly, add proper ventilation to deal with condensation in these solid-wall rooms, and set out underfloor heating where the floor build-up allows. The tiling, sanitaryware and lighting then go in over a sound, well-drained base that will not give trouble later.
Space is the constant challenge in an SW4 bathroom. The closet-wing rooms and narrow landings of Clapham terraces rarely offer much floor area, so we plan the layout carefully, using wall-hung units, walk-in showers and considered storage to make a small room feel usable rather than cramped, without wasting an inch of the footprint you have.
En-suites are a popular addition when we reconfigure the upper floors of a Clapham house, carving one out of a bedroom or a redundant box room. Bathroom work does not need planning permission, though the electrics are notifiable under building regulations, so we certify the wiring and extract properly and leave you with paperwork that stands up when you sell.
Clapham homeowners choose GS Renovation because we get the parts you cannot see right, tanking, drainage and ventilation, before the tiling ever goes on. One team handles the plumbing, electrics, heating and finish, we make the most of tight SW4 layouts, and our 30+ years mean the bathroom lasts rather than leaks.
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!

Yes. The compact closet-wing bathrooms in SW4 terraces often suit a wet room well, as removing the tray frees up floor space. The key is full tanking and correct drainage falls so the whole floor stays watertight over solid-wall construction. We waterproof properly, add good ventilation, and certify the electrics under building regulations, so the room performs for years.
