Luxury bathroom and wet-room refurbishment in Clerkenwell. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Clerkenwell, working within the warehouse conversions and new-build apartments of this EC1 quarter of Islington. With more than 30 years of experience, we build wet rooms, en-suites and space-saving family bathrooms that are properly waterproofed and ventilated, which matters more than anything when your neighbour lives directly below you.

In a stacked Clerkenwell conversion, a bathroom leak is your downstairs neighbour's ceiling, so we tank and waterproof to a standard that leaves nothing to chance. Wet rooms and walk-in showers are fully tanked before a single tile goes on, the falls are set to drain cleanly, and we upgrade extraction and ventilation to clear moisture from rooms that often sit deep inside a converted floorplate with no external window.
Drainage in these EC1 buildings is rarely straightforward. Original warehouse layouts and new-build service voids dictate where waste can run, so we plan the position of the shower, basin and WC around the existing stacks rather than assuming we can move them anywhere. Notifiable electrical work for lighting, heating and extraction is certified under building regulations, and we work within the managing agent's rules on noise and access.
Bathroom space is tight in many Clerkenwell homes, so a clever layout matters as much as a smart finish. We carve en-suites out of awkward corners, fit wall-hung sanitaryware and compact walk-in showers, and use continuous tiling and recessed niches to make a small room feel calm rather than cramped. Underfloor heating frees up the walls and keeps a stone or porcelain floor warm underfoot.
The finish is chosen to suit the home, from industrial-toned tiling that echoes a warehouse conversion to crisper schemes for a new-build apartment near the Angel. Whatever the look, the fundamentals stay the same: sound tanking, a reliable drainage route, proper ventilation and certified electrics. In a leasehold EC1 flat we confirm any freeholder approvals for altering services before the strip-out begins.
Clerkenwell owners choose GS Renovation because a bathroom in a stacked EC1 conversion has to be watertight, well drained and quiet to build. One team handles the tanking, drainage, ventilation, tiling and certified electrics, works within the managing agent's rules and confirms freeholder approvals first, all backed by 30+ years of bathrooms across Islington.
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
Every Clerkenwell project is priced on its own merits, as the cost of bathroom renovation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your property. 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).

GS Renovation knows Clerkenwell'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 Clerkenwell 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 Clerkenwell's homes are warehouse-conversion and new-build properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as concrete or steel frames, building-management rules and modern services, so the result suits the building and meets building control.
Full tanking is the answer. Before any tiling, we apply a continuous waterproof membrane across the floor and shower walls, set the falls so water drains cleanly, and seal every junction and pipe penetration. Wet rooms get particular attention because there is no tray to contain water. This protects the flat below, satisfies building regulations and gives you a bathroom you can trust for years.
