Bathroom Renovation Angel

GS Renovation renovates bathrooms across Angel and N1, from Georgian townhouses in Barnsbury to converted flats around the Angel and Clerkenwell. We deliver full waterproofing, wet rooms, en-suites and space-saving layouts, working carefully within the constraints of period and leasehold homes.

In Angel, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Angel: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Angel home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Wet rooms and tanking in Angel homes

A lasting bathroom in an Angel period home starts with proper waterproofing. We tank the walls and floors before tiling, so water stays where it should even in the solid-walled construction typical of N1 townhouses. Wet rooms and walk-in showers need particular attention to falls, drainage and the substrate beneath the tiles, and we build these up correctly rather than relying on surface sealant to do the work.

Ventilation and drainage matter as much as the finish, especially in older Angel properties where original waste runs and airflow were never designed for modern showers. We upgrade extraction to prevent damp, reroute or renew drainage where needed, and can add underfloor heating beneath tiled floors. The result is a bathroom that looks right in a period home and performs reliably for years.

Housing in Angel

Angel counts roughly 19,540 homes for Council Tax; 52% are older than 1919, 3% interwar and 44% post-war, with 84% flats and 16% houses. Since most homes here are flats, a bathroom in a flat in Angel sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.

Bathrooms above other people's ceilings in Angel conversions

84% of homes in Angel are flats, so a bathroom here is often over somebody else's ceiling. A slow leak from a failed seal under a shower tray does its damage in the flat below, and the first you hear of it is a stain on their cornice. That changes how the room is built. We test the new waste and supply runs under pressure before boarding, tank the floor as well as the walls in a shower area, and leave an access panel to the trap. The lease may also restrict where a bathroom can go, so read it before moving one.

The front windows are the other Angel question. Islington Council says a house covered by an Article 4 direction needs householder planning permission to install or replace windows on the front of the house, and the Angel conservation area (CA18) is among the borough's conservation areas. If your house is covered by such a direction, swapping a front sash for an obscured double glazed unit needs an application. For privacy, a translucent film or blind on the existing glass, or secondary glazing on the inner face, leaves the front unchanged and the sash in working order.

En-suites and space-saving layouts in N1

Period bedrooms in Angel often have room for a well-planned en-suite, and converted flats frequently need a compact main bathroom to make the most of a tight footprint. We design layouts that use every corner, choosing wall-hung sanitaryware, walk-in showers and clever storage so a small N1 space still feels considered rather than cramped, while keeping the plumbing runs sensible and accessible.

In leasehold flats near Clerkenwell and Old Street, a bathroom in a new position may need the freeholder's agreement and attention to sound insulation and waterproofing above a neighbour below. We coordinate this and work within building rules. Bathroom electrics fall under building regulations and are certified by a registered electrician or notified to building control, so your finished Angel bathroom is safe, watertight and properly documented.
