Luxury bathroom and wet-room refurbishment in Sidcup. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Sidcup, from family bathrooms in 1930s semis to new en-suites in larger interwar homes. With over 30 years of experience in DA15 and the Bexley borough, we handle the waterproofing, drainage, tiling, heating and electrics in-house, turning dated or awkward bathrooms into properly built, watertight spaces that last.

Whether you want a full wet room or a generous walk-in shower, the work starts below the surface. We tank and waterproof the walls and floor properly before a single tile goes on, because in an interwar Sidcup house a leak that tracks into the structure or the shared party wall causes far more damage than the bathroom itself. Correct drainage falls and ventilation are designed in from the outset to keep the room dry and healthy.
Once the room is fully tanked, we tile, fit the sanitaryware and add comforts such as underfloor heating for a warm floor underfoot. Ventilation is important in these houses, so we specify extraction that clears moisture properly, and any new bathroom electrics are installed and certified as notifiable work under building regulations, keeping the finished room both beautiful and compliant.
The original bathrooms and box rooms in 1930s Sidcup semis are often tight, so a big part of our work is making modest spaces work harder. We plan efficient layouts, use wall-hung sanitaryware to free up floor area, and carve out en-suites from the corner of a main bedroom or a former closet space, running the drainage and ventilation neatly to suit the interwar structure.
Every fixture is placed for real, everyday use, with the plumbing and falls set out so waste runs away cleanly rather than being forced to fit afterwards. From family bathrooms to compact en-suites, we deliver the tanking, tiling, heating and electrics as one job, so you get a hardwearing, watertight room that suits the proportions of a Sidcup home.
Sidcup homeowners choose GS Renovation because we build bathrooms to last, starting with proper tanking and waterproofing rather than tiling over problems. One team handles the drainage, ventilation, tiling, underfloor heating and certified electrics, and we plan space-saving layouts that suit tight interwar rooms. With 30+ years across DA15 and Bexley, you get a watertight, compliant finish.
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 Sidcup's homes are 1930s and interwar properties, and we renovate them regularly.

Usually, yes. We often create en-suites in Sidcup semis by using a corner of a bedroom or a former closet space, fitting wall-hung sanitaryware and planning an efficient layout to save room. The key is routing drainage and ventilation to suit the interwar structure and tanking the space fully before tiling. New bathroom electrics are notifiable under building regulations, which we certify. No planning permission is needed for internal work.
