Luxury bathroom and wet-room refurbishment in Romford. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Romford, working in the 1930s semi-detached and interwar homes that fill RM1. With over 30 years in Havering, we take the small, dated bathrooms typical of these houses and rebuild them as fully waterproofed, well-drained spaces, from compact en-suites to walk-in showers and full wet rooms.

A bathroom only lasts if the waterproofing is done properly, so in Romford homes we tank the wet areas before a single tile goes up. Whether it is a walk-in shower or a full wet room, the substrate is sealed so water cannot track into the interwar timber floors and solid walls behind. Getting this right protects the structure of these older houses, where hidden leaks can quietly cause real damage over time.
Drainage and ventilation matter just as much. We set falls correctly for wet room gullies, upgrade waste runs where the original layout was cramped, and fit proper extraction to manage the humidity that plagues small interwar bathrooms. Underfloor heating is a popular addition, warming the tiled floor and helping the room dry out. Any bathroom electrics are notifiable under building regulations, so that work is certified.
The original bathrooms in Romford's interwar semis are often tight, sometimes carved out of a small rear room upstairs. We plan space-saving layouts that make them feel larger, using wall-hung sanitaryware, walk-in showers in place of bulky enclosures, and clever storage that keeps clutter off the floor. Careful tiling and lighting choices then open the room up further without changing its footprint.
Many homeowners in these houses also add an en-suite to the main bedroom, borrowing space from a landing cupboard or an oversized room. We handle the new drainage, the ventilation and the tanking for these additions, and coordinate them with the family bathroom so the plumbing works as one system. On the generous plots of RM1 there is often scope to improve the whole first floor at once.
Romford homeowners choose GS Renovation because we build bathrooms that are properly waterproofed, well drained and ventilated, not just nicely tiled. We understand the tight, dated bathrooms of RM1's interwar semis and design space-saving layouts, wet rooms and en-suites that suit them. With certified electrics and 30+ years in Havering, the finish looks good and stays sound.
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!

Yes. A large share of Romford's homes are 1930s and interwar properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as cavity walls, regular original layouts and the generous plots that suit extending, so the result suits the building and meets building control.
Yes. The compact bathrooms in Romford's interwar semis suit a wet room well, since removing a bulky enclosure frees up space. We fully tank the area, set the drainage falls correctly, upgrade the ventilation and add underfloor heating if wanted. The tanking is essential to protect the older timber floors and walls, and any electrics are certified under building regulations.
