Luxury bathroom and wet-room refurbishment in Knightsbridge. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms and en-suites across Knightsbridge, working within the Georgian and Regency townhouses and mansion flats of SW7. With over 30 years in the Royal Borough of Kensington and Chelsea, we handle waterproofing, drainage, tiling, underfloor heating and the space planning that period homes and leasehold apartments both demand.

A bathroom in a Knightsbridge townhouse or mansion flat has to be watertight before anything else, so we tank and waterproof the walls and floor properly, particularly in wet rooms and walk-in showers where water is not contained by a tray. Correct drainage falls and mechanical ventilation are designed in from the start, which matters in solid-walled period rooms and internal bathrooms where damp has nowhere easy to escape.
Over the top of a sound waterproofing layer we tile to a high standard, run underfloor heating for warmth and comfort, and set out the sanitaryware for a clean, considered finish. In an SW7 mansion flat we also respect the sound insulation between flats and the building management rules, coordinating with the managing agent, so a new bathroom does not create a nuisance for the neighbour below.
Period townhouses in Knightsbridge were not built with today's bathrooms in mind, so fitting an en-suite often means working within a chimney recess, a landing corner or a slice taken from a bedroom. We plan space-saving layouts that make the most of tight footprints, choosing walk-in showers, wall-hung sanitaryware and concealed cisterns to keep the room feeling open despite the constraints of an older house.
In a mansion flat the picture is leasehold, so structural change is limited and moving soil pipes or drainage is rarely straightforward. We work within the freeholder's licence to alter and the building's management rules, planning the layout around the existing services where we can. Whether townhouse or apartment, bathroom electrics are notifiable under building regulations, so we certify the installation and hand over a fully compliant SW7 bathroom.
Knightsbridge homeowners choose GS Renovation for bathrooms because we get the fundamentals right, with proper tanking, drainage and ventilation before a single tile goes on. We plan clever layouts for tight period rooms, respect leasehold and building rules in mansion flats, and certify the electrics, all backed by 30+ years across the Royal Borough.

FAQ
By surveying first and writing it down afterwards. A Knightsbridge property is measured, the structure is confirmed, and the bathroom renovation scope is agreed before GS Renovation puts a figure to it. The quotation then splits into structure, services and finishes, with the Royal Borough of Kensington and Chelsea fee visible rather than bundled. Homeowners around SW7 can hold us to it, because it is in writing. Ring 07472 424 226 or email info@gsrenovationltd.co.uk to book the SW7 visit. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Usually something that could have been foreseen at survey. In listed period houses with sash windows, lime plaster and original joinery the classic hold-up on bathroom renovation is discovering the structure at an SW7 property is not what the drawings suggested, which is why GS Renovation investigates before committing to a Knightsbridge programme. Beyond that it is inspection slots and deliveries. Both are booked ahead across Kensington and Chelsea. GS Renovation investigates the structure at the SW7 property before any Knightsbridge date is committed to paper.
Aftercare is part of the job rather than an afterthought. Once bathroom renovation at your Knightsbridge home is complete, GS Renovation provides the Royal Borough of Kensington and Chelsea certificate, the engineer's documentation where the design required one, and the guarantee on installations. Snags at SW7 are dealt with by the same team. Most of our Kensington and Chelsea work comes from people we have already looked after. Email info@gsrenovationltd.co.uk to reach us. The certificate and the guarantee are handed over together at SW7.
The electrical element is, under Part P, and it must be certified. Wet systems tie into the heating and engage Part L. We install and test underfloor heating before tiling at your SW7 property, and the certification goes through Royal Borough of Kensington and Chelsea with the rest of the work.
They ask more of the preparation, which is where the difference sits. Listed period houses with sash windows, lime plaster and original joinery conceal their structure, so bathroom renovation begins with confirming what is actually carrying load at the SW7 property before anything is removed. GS Renovation appoints an engineer where the design requires one. After that the Knightsbridge job runs much like any other. Email info@gsrenovationltd.co.uk and we will explain what bathroom renovation needs confirmed before any design work begins at SW7.
Yes. Fitting en-suites into tight corners of period Knightsbridge homes is something we do regularly, using chimney recesses, landings or part of a bedroom. We choose walk-in showers, wall-hung sanitaryware and concealed cisterns to save space, tank the room properly for waterproofing, design in drainage and ventilation, and certify the electrics under building regulations so the finished en-suite is compliant and durable.
Both are covered, and often in the same week. GS Renovation is usually on more than one Kensington and Chelsea site at a time, which is why bathroom renovation in Kensington or Knightsbridge can normally be surveyed quickly. There is no travel surcharge between them. Email info@gsrenovationltd.co.uk with the SW7 postcode and we will book a visit. Quotes are free and carry no obligation. Aftercare reaches both addresses from the same team across Kensington and Chelsea.
