Luxury bathroom and wet-room refurbishment in Kensington and Chelsea. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes bathrooms and en-suites across Kensington and Chelsea, fitting out the townhouses and mews homes of SW3, SW7, W8 and W11. With 30+ years in the Royal Borough, we handle full waterproofing, drainage, tiling and heating, designing wet rooms and space-saving layouts that work within the awkward proportions of Georgian and Regency period properties.

Bathrooms in the townhouses of Chelsea and Notting Hill are often carved out of former bedrooms or landing space, on upper floors with timber joists that must stay dry. We tank and waterproof the whole area before tiling, forming falls to the drain for walk-in showers and wet rooms so water goes where it should. Correct drainage and mechanical ventilation are designed in to protect the period structure below.
Underfloor heating, tiling and the finishing work follow once the waterproofing is proven. In the tall, narrow homes across SW3 and W8, running new soil and waste pipes takes planning, so we route them discreetly through cupboards and voids. Notifiable electrical work for the bathroom is certified under building regulations, and the whole installation is designed to cope with the demands of daily use in a busy household.
The period homes of Knightsbridge, South Kensington and Holland Park rarely offer generous bathroom space, so clever layout matters. We add en-suites to principal bedrooms and reconfigure tight family bathrooms, using wall-hung sanitaryware, walk-in showers and concealed cisterns to free up floor area. Every layout is planned around the existing joists, chimney breasts and window positions of the original room.
Waterproofing standards stay the same whatever the size: full tanking, proper drainage falls and adequate extraction to prevent damp in these solid-walled properties. Underfloor heating warms cold period floors, and considered tiling and lighting lift a small space. Bathroom renovation is internal work requiring building regulations rather than planning permission, though in listed homes we check whether altering the room affects anything requiring consent.
Kensington and Chelsea owners choose GS Renovation because a bathroom in a period townhouse depends on getting the waterproofing, drainage and ventilation right on timber upper floors. We tank properly, route services discreetly and finish to a high standard, adding en-suites and wet rooms that suit tight period layouts. Thirty years across SW7, W8 and W11 stands behind the work.

FAQ
Free, always. Pricing bathroom renovation without seeing a Kensington and Chelsea house is guesswork, so the visit to SW3 is part of quoting rather than a service to bill for. GS Renovation allows enough time on site to look properly, including at the listed and conservation-area details that move the figure. Nothing is owed if you go elsewhere in Kensington and Chelsea. Ring 07472 424 226 or email info@gsrenovationltd.co.uk and we will find a Kensington and Chelsea appointment time that suits you. 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.
It varies through the year and you will get the real answer. GS Renovation will not open an SW3 property for bathroom renovation until the team can stay on it to the end, which is why a Kensington and Chelsea start date is committed rather than provisional. Approvals from Royal Borough of Kensington and Chelsea run alongside. Call 07472 424 226 and we will check the next available Kensington and Chelsea slot. Email info@gsrenovationltd.co.uk with the SW3 postcode and we will confirm the position.
Our founder has spent over 30 years on the tools, and that experience is what a Kensington and Chelsea homeowner is buying. Bathroom renovation at an SW3 address is run by one named manager, fully insured, with the Royal Borough of Kensington and Chelsea approvals coordinated rather than left with you. Installations carry a five year guarantee. Quotes are free and there is no obligation. Email info@gsrenovationltd.co.uk and we will arrange a Kensington and Chelsea survey. The Kensington and Chelsea certificate is available before any Kensington and Chelsea work starts.
Part F sets the requirement, and in practice that means mechanical extraction to outside, never into a loft void. Condensation is a persistent problem in Kensington and Chelsea's older solid-wall properties, so we size extraction properly at the SW3 address rather than fitting the smallest unit that complies.
They make the job more interesting rather than more difficult. What bathroom renovation needs in Kensington and Chelsea is proper investigation before anything structural is touched at SW3, and an engineer's design where the load path is changing. GS Renovation coordinates that as standard. Over 30 years of hands-on experience is mostly knowing where to look in Kensington and Chelsea. Ring 07472 424 226 and we will explain how bathroom renovation is planned in an SW3 house in Kensington and Chelsea.
Yes. Upper-floor wet rooms in Holland Park townhouses sit on timber joists, so full tanking and correctly formed drainage falls are essential to keep the structure below dry. We waterproof the whole area, design in proper ventilation and route new pipework discreetly. This is internal work under building regulations, not planning, though in listed homes we check first whether any consent applies.
There is no part of Kensington and Chelsea we would exclude. Bathroom renovation is carried out throughout the area and the SW3 area and across neighbouring Kensington and Chelsea, on terraces, semis and flats alike. GS Renovation knows how grand terraces and garden-square houses laid out over four and five storeys are built, which is what makes an SW3 quotation accurate. Email info@gsrenovationltd.co.uk and we will book a free survey. Building control goes through Royal Borough of Kensington and Chelsea in the usual way. Small jobs and whole-house programmes are both quoted on the same basis.
