Luxury bathroom and wet-room refurbishment in Southwark. Trusted, professional, 30+ years' hands-on experience.
GS Renovation installs bathrooms and en-suites across Southwark, in the Victorian terraces of Camberwell, the Georgian townhouses of Dulwich and the converted flats of Bermondsey. With more than 30 years of experience in SE1, SE15, SE17 and SE22, we handle waterproofing, drainage, tiling, heating and the fit-out, making the most of tight spaces in period homes.

A bathroom in a Southwark period home lives or dies by its waterproofing. Before any tile goes on, we fully tank the walls and floor, so a wet room or walk-in shower stays watertight over solid Victorian floors or the timber joists common in SE5 and SE15. We set the falls correctly to the drainage, upgrade the ventilation to control condensation in older, poorly aired rooms, and lay underfloor heating where the build-up allows for warm, dry comfort.
Space is the constant challenge in Southwark's period houses. Many bathrooms sit in a narrow rear closet wing or a boxed-in landing, so we plan layouts that earn every centimetre, using wall-hung basins and toilets, walk-in showers and slim concealed cisterns. When adding an en-suite to a Dulwich or Camberwell bedroom, we route new drainage carefully to fall correctly, boxing pipework neatly and keeping disruption to the surrounding rooms to a minimum during the build.
Bathrooms in the leasehold flats and warehouse conversions of Bermondsey, Borough and SE16 bring their own considerations. Waterproofing matters even more here, because a leak affects the flat below and the wider block, so full tanking is essential. We work within the building's rules on wet-area alterations, coordinate with the managing agent, and respect the sound insulation between flats, choosing quiet extraction and careful pipe routing so a new bathroom does not become a nuisance to neighbours.
Whatever the property, the finish is what you see every day. We tile to a high standard, from large-format porcelain to traditional metro and mosaic, and fit brassware, heated towel rails and lighting to suit the room. None of this needs planning permission, though the electrical work is notifiable under building regulations, which we handle. From a compact SE17 en-suite to a full family bathroom near Peckham Rye, we deliver a watertight room that lasts.
Southwark homeowners choose GS Renovation for bathrooms because we get the hidden work right, the tanking, drainage and ventilation, not just the tiles. With 30+ years across SE1 to SE22, we design space-saving layouts for period homes, install en-suites and wet rooms cleanly, and handle the building regulations and leasehold coordination so your bathroom is watertight and worry-free.
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!
FAQ
We price each Southwark project individually, because the cost of bathroom renovation depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. 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.
A straightforward Southwark project can be done in a couple of weeks, while a larger bathroom renovation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.
GS Renovation knows Southwark's homes and how to renovate them properly. We handle the structure, the services and the finishes, deal with building control for you, and leave you with work that is certified, guaranteed and built to last.
Yes. Bathroom electrics in Southwark are notifiable under Part P and must be certified, and any drainage, ventilation or structural changes must meet building regulations. We include certified electrical work and manage building control on every bathroom project.
Yes. A large share of Southwark's homes are period, Georgian and listed properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as conservation and listed-building rules, solid walls and original period features, so the result suits the building and meets building control.
Yes. In a small Camberwell bathroom a wet room is often the best use of space, removing the bulk of a bath and enclosure. The key is full tanking of the floor and walls, correct falls to a well-placed drain, and good ventilation, all of which we install over the solid or timber floors typical of these Victorian homes. No planning permission is required.
