Luxury bathroom and wet-room refurbishment in Barnes. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Barnes, working within the tight, awkward spaces typical of SW13's bay-fronted Victorian and Edwardian terraces and period cottages. With more than 30 years in South West London, we handle the waterproofing, drainage, tiling, heating and finish in one go, turning dated or cramped bathrooms into rooms that work.

A wet room only lasts if the waterproofing is done properly, and in a Barnes terrace with timber suspended floors that matters even more. We tank the whole area with a bonded membrane behind the tiling, form the falls to the drain, and make sure the shower cannot find its way into the joists below. Walk-in showers suit the narrower bathrooms of an SW13 home, giving a clean, open feel without a bulky enclosure.
Getting waste and ventilation right is half the job in a period bathroom. We reroute drainage to fall correctly, upgrade extraction to clear moisture from a room with little natural airflow, and often add underfloor heating so tiled floors are warm underfoot and dry quickly. Tiling is set out to suit the proportions of the room, and everything is finished to a standard that copes with daily family use in a Barnes home.
Barnes terraces rarely offer generous bathrooms, so clever planning counts. We carve en-suites out of a corner of a bedroom or the space over the stairs, choose compact sanitaryware, and use wall-hung units and recessed niches to keep floor area free. Sliding doors, concealed cisterns and considered lighting all help a small SW13 bathroom feel bigger. The aim is a room that is practical for a busy household yet still feels calm.
A new bathroom inside the house does not need planning permission, and most Barnes projects run straight from design to install. We manage the lot, moving pipework and waste, adding the extraction, running the electrics and fitting underfloor heating, then tiling and finishing. New bathroom wiring is notifiable and certified under building regulations. Working in an occupied home, we protect the rest of the house and keep to a clear, agreed timetable.
Barnes homeowners choose GS Renovation for bathrooms because the parts you cannot see, the tanking, the falls and the ventilation, are done right, not just the tiles on top. We work confidently in the tight spaces of SW13 terraces, manage every trade in-house, and certify the electrics under building regulations. With 30+ years locally, your bathroom is built to stay watertight.
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. A large share of Barnes's homes are Victorian and Edwardian terraced properties, and we renovate them regularly.

Yes. In Barnes we often create en-suites by borrowing a corner of a bedroom or the awkward space over the stairs, using compact, wall-hung fittings to save room. It needs full tanking, proper drainage falls and good extraction, especially in a period house with timber floors. No planning permission is required for an internal en-suite, though the new wiring is certified under building regulations. We handle the whole job in-house.
