Luxury bathroom and wet-room refurbishment in Eltham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Eltham, working within the layouts of 1930s semi-detached and interwar houses where space is often tight upstairs. With over 30 years of experience in SE9 and the Royal Borough of Greenwich, we deliver fully waterproofed, well-drained bathrooms and en-suites finished to a lasting standard.

A bathroom that lasts starts with proper waterproofing. Before any tile goes on, we tank the walls and floor in wet areas so moisture cannot track into the structure of an older SE9 house. For walk-in showers and full wet rooms we install the correct falls, drainage and a sealed substrate, which matters in interwar homes where original floors are not always level and hidden leaks can rot timbers over time.
Ventilation is just as important as tanking. Eltham bathrooms in these houses can suffer from condensation and damp if extraction is poor, so we fit properly rated extractor fans and, where needed, improve the airflow. Add underfloor heating, quality tiling and good lighting, and the room stays warm, dry and free of the mould that plagues neglected bathrooms in period property.
Interwar Eltham houses often have a generous main bedroom that can give up a corner for an en-suite, or a boxroom that suits a compact shower room. We plan the layout carefully around existing soil pipes and joists, since moving drainage in these homes takes thought rather than guesswork. Careful positioning of the WC, basin and shower makes even a small space feel usable rather than cramped.
In the family bathroom, small changes to the layout can free up real room, such as swapping a bulky bath for a walk-in shower or repositioning the basin to open the floor. Bathroom electrics are notifiable under building regulations, so we certify new circuits and zoned lighting correctly. The result is a bathroom that fits the proportions of a 1930s SE9 house and works for a busy household.
Eltham homeowners choose GS Renovation because a bathroom is only as good as its waterproofing and drainage, which is easy to get wrong in an older SE9 house. We tank properly, sort ventilation, plan around existing soil pipes and certify notifiable electrics. With 30+ years across the Royal Borough of Greenwich, we deliver en-suites and family bathrooms built to stay dry and warm.
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!
