Luxury bathroom and wet-room refurbishment in Finchley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Finchley, from the family bathrooms of 1930s semis to new en-suites in larger interwar homes in N3. With over 30 years of experience across Barnet, we take on the waterproofing, drainage, tiling and finishing as one project, delivering wet rooms and modern bathrooms built to last in solid older houses.

A well-built bathroom in a Finchley house starts with proper waterproofing. We tank the walls and floor before tiling so water never reaches the structure, which matters in older interwar houses where a leak can track into timber floors below. From there we build walk-in showers and full wet rooms with the falls set correctly to the drain, and we finish with quality tiling, underfloor heating and ventilation that clears moisture and protects the room long term.
The bedrooms in Finchley's larger 1930s and interwar homes often have room for an en-suite, and we carve these out without wasting space, running new drainage and extract back to the existing stacks. On tighter plots we plan compact layouts that still feel generous, and every bathroom includes the notifiable electrical work certified under building regulations, from the lighting and shower circuits to the underfloor heating.
Original bathrooms in Finchley semis can be narrow, with a window on one wall and the soil stack fixed in place, which limits where fittings can go. We design around those constraints, using wall-hung units, walk-in enclosures and considered storage to make a small room feel open. Where the layout allows, we reconfigure the space to fit a proper shower and a separate bath, a common request on these family homes.
Good drainage and ventilation are as important as the tiles. We upgrade the extract, set the pipework falls correctly and tank thoroughly so the finished bathroom stays sound in a house that may be 90 years old. Underfloor heating warms tiled floors that would otherwise feel cold, and we handle the plumbing, electrics and finishing together so the room is completed properly rather than in disconnected stages.
Finchley homeowners choose GS Renovation because we build bathrooms that stay watertight in older interwar houses, not just ones that look good on day one. We tank and waterproof thoroughly, set the drainage and ventilation right, certify the electrics under building regulations and finish the tiling and heating to a high standard, backed by 30+ years across Barnet.
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!
