Luxury bathroom and wet-room refurbishment in Old Street. Trusted, professional, 30+ years' hands-on experience.
Bathrooms in Old Street sit above other homes, so waterproofing is everything. GS Renovation renovates en-suites and family bathrooms across EC1, from warehouse conversions near Clerkenwell to new-build apartments around the Angel. With 30+ years in North London, we tank, tile and plumb to standards that protect the flat below and satisfy the managing agents these Islington blocks answer to.

In a stacked EC1 apartment a leaking bathroom is not your problem alone, it is the ceiling of the flat downstairs. That is why we tank every wet area fully before a single tile goes on, bonding a waterproof membrane across floor and walls and forming falls that carry water to the drain. Wet rooms and walk-in showers demand this discipline most, and we detail the thresholds and junctions so nothing ever finds its way through.
Drainage and ventilation take planning in these buildings, where soil stacks and extract routes are fixed by the original design. We work with the existing risers rather than against them, add mechanical ventilation to clear moisture, and coordinate any changes with the managing agent. Underfloor heating, recessed lighting and quality tiling complete a bathroom that is warm, dry and quiet, with the sound insulation these Islington flats need between floors.
Apartments around Old Street rarely have space to spare, so an added en-suite or a reworked bathroom has to earn every centimetre. We plan compact layouts with wall-hung sanitaryware, slimline cisterns and walk-in showers that feel generous without stealing floor area. Where a converted warehouse offers a taller ceiling, we can exploit it with concealed services and dramatic tiling; where a new-build is tight, we design ruthlessly around the fixed plumbing.
An en-suite carved from a bedroom means running new waste and supply through an occupied, managed flat, so we agree isolations and access with the managing agent before starting. Notifiable electrical work near water is certified, extraction is sized to prevent damp, and the whole room is tanked to protect the property below. The result is a hard-wearing, well-ventilated bathroom finished to suit the character of the EC1 home it serves.
In a stacked Old Street block, bathroom failures travel downward, so getting the waterproofing right is the whole job. GS Renovation tanks properly, respects the fixed drainage and ventilation of EC1 buildings, and coordinates access with the managing agent. Thirty years across Islington means bathrooms that stay dry, pass building control on their electrics and never trouble the flat below.
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!
