Luxury bathroom and wet-room refurbishment in St John's Wood. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes bathrooms across St John's Wood, from en-suites in NW8 mansion flats to family bathrooms in the area's bay-fronted Victorian and Edwardian terraces. With more than 30 years in Westminster, we handle the waterproofing, drainage, tiling, heating and fit-out so a period bathroom is dry, warm and properly finished for years.

The bathrooms in a St John's Wood terrace are often tucked into the rear closet wing or carved out of a former bedroom, where solid walls, timber floors and older drainage make leaks a real risk. We tank and waterproof the wet areas properly before any tile goes down, so moisture cannot track into the structure below. Getting the falls, the drainage and the mechanical ventilation right is what keeps a period bathroom sound.
Walk-in showers and full wet rooms are popular here, but they demand a fully tanked floor and walls and a reliable fall to the drain, especially over a suspended timber floor. We form the substrate, tank it, then tile in stone, porcelain or mosaic and add underfloor heating to counter the chill of a period property. Ventilation is sized to clear moisture so the finish lasts rather than blackening at the edges within a year.
Space is tight in St John's Wood period homes, so we plan bathrooms and en-suites to make the most of an awkward footprint, borrowing from a landing, a closet wing or a chimney recess to fit a shower, basin and WC without it feeling cramped. Careful setting-out of the drainage runs and the layout means the fittings sit where they work, not just where the old pipes happened to run.
In the mansion flats around NW8, a leaking bathroom affects the flat below, so waterproofing, sound insulation and the freeholder's rules on wet works all matter, and the managing agent will usually need to agree the works first. We tank thoroughly, upgrade the drainage and ventilation, and finish with tiling, underfloor heating and the fittings you choose. One team runs the plumbing, electrics and tiling so the bathroom is watertight and complete.
St John's Wood homeowners choose GS Renovation because a bathroom in a period home lives or dies on the waterproofing beneath the tiles, and we get that right first. With 30+ years in NW8 terraces and mansion flats, we tank properly, sort drainage and ventilation, handle leasehold wet-works rules, and finish with tiling, underfloor heating and fittings that last.
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 St John's Wood's homes are Victorian and Edwardian terraced properties, and we renovate them regularly.

The key is proper tanking. In a St John's Wood terrace the bathroom often sits over a suspended timber floor, so we form a solid substrate, fully waterproof the floor and walls, and build in a reliable fall to the drain before tiling. We also fit adequate mechanical ventilation. Together these keep moisture out of the structure and stop the leaks older period bathrooms are prone to.
