Luxury bathroom and wet-room refurbishment in Lewisham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms, en-suites and wet rooms across Lewisham, working within the Victorian and Edwardian terraces of Deptford, Catford and Forest Hill. With 30+ years in SE8, SE13 and SE26, we handle the waterproofing, drainage, tiling and heating in-house, making the most of the often tight spaces these period homes offer.

Water is the enemy in an old terrace, where timber floors and lath-and-plaster walls do not forgive leaks. Before any tiles go on, we tank the space properly with a waterproof membrane across the floor and up the walls in the shower zone. In a walk-in shower or full wet room we form the falls to the drain, bond the membrane and pressure test, so water goes where it should and the structure below stays dry.
Ventilation and drainage need equal care in these houses. We fit proper extraction to clear moisture and protect the plaster and joinery, and we run new soil and waste pipes to suit the existing stack rather than fighting it. Underfloor heating warms tiled floors and helps the room dry quickly, a real benefit in a period bathroom that was often a cold afterthought bolted onto the back of the closet wing.
Space is the constant challenge in Lewisham terraces, where the family bathroom often sits in the narrow closet wing. Careful planning wins back room, a wall-hung basin and toilet to free the floor, a walk-in shower instead of a bulky enclosure, and a slim heated towel rail. We can steal a little from a landing or an oversized bedroom to create the en-suite many SE23 and SE26 families want without losing a proper bathroom.
Loft conversions on these terraces usually call for an en-suite too, where low eaves and the position of the soil stack shape what is possible. None of this internal work needs planning permission, but the electrics in a bathroom are notifiable under building regulations, which we register and certify. From tiling and lighting to the last coat of paint, one team fits the whole bathroom, so the finish and the waterproofing are the responsibility of a single contractor.
Lewisham homeowners choose GS Renovation because we get the hidden work right, the tanking, drainage and ventilation that keep a period bathroom sound, as well as the finish you see. With 30+ years across SE4, SE8 and SE14 terraces, one team fits the whole room, so there is no gap between the waterproofing and the tiling.
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!
