Luxury bathroom and wet-room refurbishment in Bexley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Bexley, fitting family bathrooms, en-suites and wet rooms into the 1930s semis and interwar homes of Bexleyheath, Sidcup and Welling. Working throughout DA5, DA6, DA7 and SE2, we handle the waterproofing, drainage, tiling and heating in one job. With 30+ years in the borough, we build bathrooms that stay watertight for years.

Fitting a second bathroom into a 1930s Bexley semi usually means borrowing space, from a corner of a bedroom for an en-suite to the box room above the stairs. We work out where the soil pipe and drainage can run, add proper mechanical ventilation to clear the moisture, and tank the walls and floor before a single tile goes on. Getting the waterproofing right first is what keeps a period house dry.
Wet rooms suit these houses well, doing away with the tray and giving a level, walk-in shower that is easy to use and easy to clean. On the timber suspended floors common in interwar semis we reinforce and prepare the deck, lay a bonded waterproof membrane, and set the falls so water runs to the drain. Underfloor heating beneath the tiles takes the chill off the solid, north-facing bathrooms these houses often have.
The main family bathroom in a Bexley semi is often the original small room, tiled decades ago and long past its best. We strip it back, renew the concealed plumbing and waste, and re-plan the layout so a bath, a decent shower and storage all fit. Space-saving fittings, a wall-hung basin and a shower over the bath make the most of the modest footprint these interwar rooms were built with.
Behind the tiles, the detail matters. We use tanking and quality waterproofing around the wet zones, seal the junctions properly and ventilate the room so the damp that plagues older Bexley houses does not take hold. New bathroom electrics, from the shower to the extractor and the lighting, are notifiable under building regulations and certificated accordingly. The result is a warm, dry, easy-to-clean bathroom finished to last.
Bexley homeowners choose GS Renovation because a bathroom that leaks is an expensive mistake, and we build ours to stay dry. Our own team handles the drainage, tanking, tiling, heating and electrics, so the waterproofing is never someone else's problem. With 30+ years fitting bathrooms into interwar semis across the borough, we deliver a room that looks right and performs for the long term.

FAQ
There is no single figure, because bathroom renovation is priced from the survey rather than a rate card. At a DA1 address the cost follows the structure involved, the access, and how much making good the 1920s and 1930s suburban construction demands. GS Renovation shows the Bexley Council building control fee on its own line, and Bexley homeowners get that breakdown in writing. You have the written bathroom renovation figure within days of the DA1 visit, anywhere in Bexley. 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.
Always. Running bathroom renovation without a programme is how a Bexley project drifts, so the sequence for your DA1 home is agreed before anyone arrives. GS Renovation keeps one team on the Bexley site rather than splitting it across jobs, which is the practical reason the dates hold. Variations are re-programmed and agreed in writing with Bexley Council notified where needed. Ring 07472 424 226 and we will explain how a DA1 programme is held in practice.
One accountable team, full insurance, and no surprises on the invoice. GS Renovation carries out bathroom renovation at your DA1 address with its own people, agrees any variation in writing first, and hands over the Bexley Council completion certificate at the end. That document matters when a Bexley property is sold. Free quotes and no obligation apply across Bexley. Email info@gsrenovationltd.co.uk and we will arrange a visit. The Bexley certificate is yours at completion.
The electrical element is, under Part P, and it must be certified. Wet systems tie into the heating and engage Part L. We install and test underfloor heating before tiling at your DA1 property, and the certification goes through Bexley Council with the rest of the work.
Many times, and we can give you addresses. Interwar semis and short terraces with hipped roofs and rear kitchens dominate that part of Bexley, so bathroom renovation on them is routine work for GS Renovation rather than something we adapt to. The 31 public MyBuilder reviews behind our 4.9 rating cover the same kind of project. Ring 07472 424 226 and we will point you at recent work in Bexley. Email info@gsrenovationltd.co.uk and we will send DA1 addresses where bathroom renovation of this kind was carried out.
Yes. Upstairs wet rooms are very doable in Bexley's 1930s semis, but the timber suspended floor needs proper preparation. We reinforce the deck where needed, lay a fully bonded waterproof membrane, and set the floor falls so water drains correctly. Good ventilation and careful tanking around the shower area keep the room and the ceiling below completely dry. Underfloor heating is a popular addition.
Almost always, and it is a fair question to ask any contractor. Bathroom renovation across Bexley is core work for GS Renovation rather than an occasional job, so there is usually a DA1 project or a Bexley one under way. Ask to speak to those clients. Call 07472 424 226 and we will arrange it. Seeing finished work in Greenwich is worth the trip. Nothing about a DA1 address is withheld if you ask.
