Luxury bathroom and wet-room refurbishment in Croydon. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites across Croydon, from the 1930s semis of Purley and Coulsdon to the interwar and Victorian homes around Addiscombe and SE19. With over 30 years in CR0, CR2 and CR7, we handle the waterproofing, drainage, tiling, heating and every trade in-house.

A well-built Croydon bathroom starts with what you cannot see. Before any tile goes down we tank and waterproof the floor and the shower zone, so wet rooms and walk-in showers stay dry for the long term rather than failing at the edges. We form the falls to the drainage, set the ventilation to clear moisture and only then tile out, whether that is large-format porcelain or classic metro across the walls.
In the interwar semis common across Purley and Coulsdon we often reconfigure a dated 1930s bathroom into a walk-in shower with underfloor heating and a heated towel rail. Where drainage needs rerouting to suit the new layout, we handle the pipework properly so falls and traps meet building regulations, and the room works reliably every day, not just on the day it is finished.
Many Croydon homeowners want to carve an en-suite out of a bedroom or convert an old box room, and the interwar semis around CR7 and SE25 usually have the space to make it work. We plan the layout to fit a compact shower, basin and WC without cramping the bedroom, then run new hot and cold supplies, waste and ventilation to the new position, coordinating soil connections carefully.
In the older Victorian and period homes near Crystal Palace and SE19, awkward proportions and chimney breasts call for a made-to-measure approach, with fittings chosen to suit the room rather than forced into a standard grid. Underfloor heating, recessed niches and considered lighting all help a smaller Croydon bathroom feel generous. Every element, from first-fix plumbing to the final seal, is delivered by one team.
Croydon homeowners choose GS Renovation because a lasting bathroom depends on the waterproofing, drainage and ventilation being right, not just the tiles. We deliver every stage in-house to one standard, with notifiable electrics certified under building regulations. With 30+ years across CR0, CR2 and CR7, we build wet rooms and en-suites that stay reliable for years.
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. The key in a Purley interwar semi is proper tanking and waterproofing under the tiles, with the floor falls set correctly to the drain and good ventilation to clear moisture.
