Bathroom Renovation Kilburn

Bathrooms in Kilburn's mansion blocks and period flats are often tucked into tight spaces with original pipework running between the storeys. GS Renovation draws on our founder's 30+ years on the tools to fit bathrooms across NW6, tanking and waterproofing them properly, improving drainage and ventilation, and squeezing smart layouts out of the smallest rooms.

In Kilburn, 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 Kilburn: 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 Kilburn 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 en-suites in Kilburn

In a Kilburn flat, waterproofing is everything, because a leak travels straight down into the home below and quickly becomes a dispute with your neighbour and the managing agent. We fully tank wet rooms and walk-in showers before a single tile goes on, sealing the floor and walls so water has nowhere to go. Proper falls to the drain, a well-sized waste and mechanical ventilation stop damp taking hold in a room with little natural airflow.

Period flats in NW6 rarely have a spare room to sacrifice, so we often carve an en-suite out of a bedroom corner or a redundant cupboard. Careful planning of the soil pipe and drainage runs is essential, since moving waste connections in a flat is far harder than in a house. We add underfloor heating under the tiles for warmth without radiators eating wall space, and design every fitting around the room you actually have.

Housing in Kilburn

Roughly 17,940 dwellings sit on the valuation list for Kilburn. 8% are houses and 92% flats, and by age 48% predate 1919, 2% are interwar and 49% post-war. Where most homes are flats, a bathroom in a flat in Kilburn sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.

A shower on a concrete floor in a post-war Kilburn flat

49% of homes in Kilburn were built after 1945, and in a post-war block the bathroom floor is often a concrete slab with the flat below directly underneath. A level access shower needs its waste below the finished floor, and the slab gives no void to run it in. Coring down through the slab puts the pipe in the neighbour's ceiling and cuts the freeholder's structure. So in a post-war Kilburn flat a walk-in shower usually means a raised floor across the room, a shallow tray with a step, or a drain position close to the stack.

Where a new bathroom is being created rather than refitted, the Brent paperwork is short. In Brent a building notice applies to residential use only and covers smaller projects such as creating a bathroom, and work can start once the notice is accepted, usually within 48 hours. That speed does not replace the lease. In a Kilburn block the licence to alter for a new bathroom, particularly one over someone else's bedroom, can take far longer than the building notice, so apply for the licence first.

Space-saving bathrooms in Kilburn flats

The classic mansion-flat bathroom is small, and the goal is to make it feel larger without moving walls we are not allowed to touch. Wall-hung basins and toilets free the floor, a walk-in shower replaces a bulky bath where it suits, and large-format tiles with slim grout lines calm a busy space. Good lighting, a mirrored cabinet and a heated towel rail finish a compact NW6 bathroom without crowding it.

Because new circuits and circuit changes near the bath or shower are notifiable under building regulations, the lighting, extract and heating circuits are installed to the right zones and certified by a registered electrician under Part P. In a leasehold flat we check the lease and, where the works are significant, keep the managing agent informed, mindful of the sound insulation and the neighbours below. New bathrooms and en-suites do not need planning permission, so the focus stays on waterproofing, drainage and a durable, well-finished room.

A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Brent Council, and doing it without consent is a criminal offence.
