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.

FAQ
There is no going rate worth quoting, because scope varies more than the market does. A simple bathroom renovation job near DA15 and a complicated one elsewhere in Sidcup are different pieces of work. GS Renovation surveys and prices each on its merits, with the Bexley Council element shown separately. Ring 07472 424 226 for an honest steer on your 1930s and interwar property, or email info@gsrenovationltd.co.uk with the DA15 address and we will book a free survey. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Yes, more often than not. GS Renovation runs bathroom renovation at a DA15 property with dust sheeting, sealed openings and a clear-up at the end of each day, which is what makes living alongside it workable in a Sidcup home. Where the 1930s and interwar layout makes that impractical we say so before you commit. The decision stays yours throughout the Bexley project. Ask on 07472 424 226 what a 1930s and interwar DA15 property typically means in practice.
Enough to know where the problems hide in a DA15 property before quoting. Bathroom renovation in 1930s and interwar housing throws up variation that a modern estate does not, and 30 years of hands-on experience is what turns that into an accurate Sidcup figure rather than a cautious one. GS Renovation has been incorporated since 2023. The experience behind it is considerably older. Ask on 07472 424 226 about Bexley projects. References near DA15 are given as addresses, not testimonials.
Yes. Bathroom electrics in Sidcup are notifiable under Part P and must be certified, and drainage, ventilation and any structural change must meet building regulations. GS Renovation includes certified electrical work and manages Bexley Council building control on every DA15 bathroom.
Not if the work is planned around them, which is what we do. Cornice, fireplaces, sash windows and original floors at a DA15 property are identified before bathroom renovation begins, and GS Renovation agrees with you which are being retained. Protection goes up before any structural work starts. Reinstatement afterwards is matched rather than approximated in the Sidcup house. GS Renovation will explain how bathroom renovation protects original detail at a DA15 address in Sidcup.
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.
Every part, houses and flats alike. GS Renovation works across Sidcup and the DA15 area and much of South East London, so bathroom renovation at your DA15 address is straightforward to service. The constraint is capacity rather than geography. Call 07472 424 226 early if the Bexley project has a deadline attached. We will tell a Sidcup homeowner honestly when the next slot is. Small jobs are as welcome as large ones here, and the written quotation follows within days.
