Luxury bathroom and wet-room refurbishment in Welling. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Welling, working within the 1930s semi-detached and interwar houses of DA16 where the original bathrooms are often small and dated. From full wet rooms to space-saving en-suites, we deliver proper waterproofing and clean finishes. With 30+ years in Bexley, one team handles the plumbing, drainage, tiling and electrics.

A bathroom that lasts starts with what you cannot see. We tank and waterproof the walls and floor properly before any tile goes on, which matters in the interwar Welling houses where suspended timber floors need protecting from moisture. For a walk-in shower or a full wet room we form the falls correctly so water drains where it should, then tile over a sound, sealed substrate rather than trusting the grout alone to keep water out.
Drainage and ventilation are planned alongside the waterproofing. We make sure waste runs fall correctly to the existing soil stack on your DA16 semi, and we fit extraction that clears moisture so the room stays fresh and free of the damp and mould that plague poorly ventilated bathrooms. Underfloor heating is a popular addition, warming the floor and helping the room dry quickly after use through the colder months.
The original bathrooms in Welling's 1930s semis are rarely large, so clever planning earns its keep. We rethink the layout to gain usable space, choosing sanitaryware and a shower enclosure that suit the real dimensions, and using wall-hung units and recessed shelving to keep the floor clear and the room feeling bigger than its footprint. Small changes to where the basin and WC sit often unlock a far more comfortable bathroom.
En-suites are a frequent request as families reconfigure the interwar upstairs, often carved from a corner of a main bedroom or a boxroom. We handle the new drainage, the concealed plumbing and the notifiable electrics, and tile and finish the room to match the standard of the rest of the house. Whether it is the family bathroom or a compact en-suite, we make every centimetre of a DA16 home work.
Welling homeowners choose GS Renovation because we get the hidden work right, the tanking, the drainage falls and the ventilation, before the tiling that everyone sees. We plan clever layouts that suit the compact bathrooms of interwar DA16 semis. With 30+ years in Bexley, one team delivers a watertight, well-finished bathroom with the electrics certified correctly.
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!
