Bathroom Renovation Highbury

GS Renovation renovates bathrooms across Highbury, fitting wet rooms, en-suites and family bathrooms into the Victorian and Edwardian terraces near Highbury Fields. We tank and waterproof properly, sort drainage and ventilation, and make the most of the tight spaces these period homes provide.

In Highbury, 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 Highbury: 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 Highbury 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.

Waterproofing period bathrooms in Highbury

Bathrooms in Highbury terraces are often carved out of the rear closet wing or a first-floor return, on suspended timber floors that must be waterproofed correctly. Before any tile goes down we tank the walls and floor, bond a decoupling membrane over the timber, and seal every junction so water cannot reach the structure below. This matters especially in a wet room, where the whole space effectively becomes the shower area.

Ventilation and drainage need equal care in N5's older houses. We install extraction that clears moisture from solid-walled rooms with little natural airflow, reroute soil and waste pipes where the layout changes, and set the falls correctly so a walk-in shower drains cleanly. Underfloor heating warms tiled floors and helps keep the room dry, and every new electrical circuit is certified under Part P by a registered electrician.

Housing in Highbury

The valuation list shows roughly 7,960 homes in Highbury, of which 55% are pre-1919, 4% interwar and 37% post-1945, split 79% flats to 21% houses. Since most homes here are flats, a bathroom in a flat in Highbury sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.

A new bathroom above someone else's ceiling in Highbury

In Highbury 79% of homes are flats, so a bathroom refit here is often a bathroom above another household's living room or bedroom. The lease may say where wet rooms can go. Moving a bathroom from above the bathroom below to above a bedroom is the change a freeholder has most reason to question, since a leak or a noisy waste then lands in the wrong room. Reading the lease before the layout is drawn saves a design that cannot be built. Where the bathroom stays in its footprint, the discussion with the freeholder is usually short.

The floor itself needs attention in the older stock: 55% of Highbury homes were built before 1919, whether they are now whole houses or flats. The joists under an old bathroom are often notched for earlier pipework, and a new floor is the chance to repair them, lay a stiff deck and fit the waterproofing as a continuous layer turned up the walls. We pressure test new pipework before the floor is closed, and where the ceiling below is lath and plaster we agree with the neighbour how it is protected during the strip out, since hammering above an old ceiling can loosen its key.

Space-saving bathrooms for Highbury homes

Space is the constant challenge in Highbury's terraces, where an en-suite may need to fit into an alcove and a family bathroom into a narrow return. We plan layouts that use every inch, with wall-hung sanitaryware, concealed cisterns, walk-in showers and slimline furniture that suit the proportions of a period room. Making the most of a compact footprint is often the difference between a cramped bathroom and a comfortable one.

Where a new en-suite is added to a Highbury bedroom, we form the partitions, run new pipework and ventilation, and tie the drainage back to the existing stack. In upper-floor bathrooms we check the joists and add support where heavy stone or a filled bath increases the load. Tiling, underfloor heating, lighting and the final fit-out are all completed by our own team, so the bathroom is delivered ready to use.

• Pressure and leak testing before any tiling starts
• Soil pipe and waste re-routing within the floor build-up
