Luxury bathroom and wet-room refurbishment in Wandsworth. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refits bathrooms across Wandsworth, working with the compact layouts typical of the borough's mansion blocks and period flats in SW12, SW17 and SW18. With more than 30 years of experience, we tank, waterproof and fit wet rooms, en-suites and family bathrooms, paying close attention to drainage, ventilation and the sound insulation that flats above and below demand.

In a Wandsworth mansion flat there is always a home below, so waterproofing is where a bathroom project stands or falls. We fully tank the walls and floor before tiling, form the falls to the drain on wet rooms and walk-in showers, and take extra care with sound insulation and pipe boxing to keep noise from carrying between flats. Getting this right protects both your home and the leaseholder beneath you.
Drainage and ventilation need proper thought in these SW11 and SW18 blocks, where soil stacks and extract routes are often fixed. We plan the layout around the existing services, upgrade the extraction to clear moisture and prevent damp, and coordinate with the managing agent where communal stacks are involved. The result is a bathroom that is watertight, well ventilated and finished to a standard that suits the building.
Period flats around Balham and Tooting rarely offer a generous bathroom, so clever planning matters. We reconfigure tight rooms to fit a walk-in shower, a wall-hung basin and concealed cistern, freeing up floor space and light. Where an en-suite is wanted off a main bedroom, we find the drainage route first and design the layout around it rather than forcing fixtures where the pipework cannot reach.
Underfloor heating warms the floor without taking wall space, and considered tiling and lighting make a small room feel larger. All the notifiable electrical work is certified under building regulations, and we handle the tiling, plumbing and finishing in-house. Because bathrooms are internal work, no planning permission is needed, so the focus stays on a durable, watertight and comfortable result built to fit your flat.
A Wandsworth bathroom sits above someone else's ceiling, so waterproofing, drainage and sound insulation are not optional extras. GS Renovation tanks properly, plans around fixed soil stacks and coordinates with managing agents in leasehold blocks. With 30+ years across SW8 to SW18, you get a watertight, well-ventilated bathroom, certified electrics and a tidy install in your occupied home.
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!
