Luxury bathroom and wet-room refurbishment in Kensington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes bathrooms and en-suites across Kensington, in the Georgian and Regency townhouses of W8 and the period mansion flats near Knightsbridge and South Kensington. With over 30 years in the Royal Borough of Kensington and Chelsea, we handle the waterproofing, drainage, tiling, heating and fit-out on every project we take on.

A lasting bathroom in a period Kensington home starts with proper waterproofing. We tank the walls and floor before tiling, which matters in tall townhouses where a leak can travel through several floors of original plaster and joinery below. Walk-in showers and wet rooms need falls formed accurately and the substrate sealed, so we build up the layers correctly rather than relying on the tiling alone to keep water out.
Drainage and ventilation are the parts homeowners rarely see but always feel. In W8's older houses, existing soil pipes and vents can be awkward to route, so we plan the runs early to keep gradients right and avoid damp. Extraction is sized to clear moisture from an internal or lower-ground bathroom, protecting your new finishes and the period fabric around them for years after the work is finished.
Period Kensington homes were not built with en-suites, so creating one often means borrowing space from a bedroom, a landing or a chimney recess. We design layouts that fit a shower, basin and WC into a tight footprint without feeling cramped, using wall-hung fittings and concealed cisterns to save room. Underfloor heating frees the walls of radiators and warms stone or tiled floors on the cooler lower levels of a townhouse.
In leasehold mansion flats, bathroom work must respect the flat below, so waterproofing and sound insulation are essential and the lease may require the freeholder's consent for moving wet areas. We coordinate with the managing agent on water isolation and working hours. All electrical work in a bathroom is notifiable under building regulations and certified, so your finished en-suite near Holland Park is safe and fully documented.
Kensington owners choose GS Renovation because a bathroom is only as good as its waterproofing, drainage and ventilation, and we get those right first. One team manages the tanking, tiling, heating and fit-out, working cleanly in occupied townhouses and mansion flats and respecting listed fabric where it matters, backed by more than 30 years in the Royal Borough.
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!
