Luxury bathroom and wet-room refurbishment in Kilburn. Trusted, professional, 30+ years' hands-on experience.
Bathrooms in Kilburn's mansion blocks and period flats are often tucked into tight spaces with original pipework running between the storeys. GS Renovation has spent 30+ years fitting bathrooms across NW6, tanking and waterproofing them properly, improving drainage and ventilation, and squeezing smart layouts out of the smallest rooms.

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.
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 the electrical work in a bathroom is notifiable under building regulations, we install and certify the lighting, extract and heating to the right zones and standards. 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.
Kilburn homeowners trust GS Renovation with bathrooms because we get the hidden work right, the tanking, the falls, the drainage and the ventilation, that keeps a flat leak-free and the neighbours happy. We certify the notifiable electrics, work cleanly through communal access, and bring 30+ years across NW6 to layouts that make the most of a tight period room.

FAQ
Variation almost always comes from what has been left out. GS Renovation prices bathroom renovation after a survey at the NW6 property, covering structure, trades, approvals and reinstatement, so the total looks higher than a quote covering half of it. A Kilburn homeowner comparing like with like usually finds the gap narrows. That is worth doing before anyone starts work in Brent. Ring 07472 424 226 and GS Renovation will go through the NW6 quotation with you line by line. 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). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
It varies through the year and you will get the real answer. GS Renovation will not open an NW6 property for bathroom renovation until the team can stay on it to the end, which is why a Kilburn start date is committed rather than provisional. Approvals from Brent Council run alongside. Call 07472 424 226 and we will check the next available Brent slot. Email info@gsrenovationltd.co.uk with the NW6 postcode and we will confirm the position.
An itemised quotation, a written programme and one named project manager. For bathroom renovation at an NW6 property that also means full insurance, Brent Council building control coordinated on your behalf, and a five year guarantee on installations. GS Renovation protects the Kilburn site and clears up daily. You deal with the same people from first survey to final certificate. Ring 07472 424 226 to hear how a Brent job runs. The Brent certificate follows completion.
Not for internal work. Converting a bedroom to a bathroom in a Kilburn house is an internal alteration, so planning is not engaged, though building regulations are. External changes such as a new soil vent pipe on an NW6 property may need permission in a conservation area.
Always. Applying a standard detail to Edwardian mansion flats with high ceilings and long internal corridors is how original features get damaged, so GS Renovation plans bathroom renovation around what the NW6 property actually is. The engineer's design covers the structure; the finishing is matched to what is already in the Kilburn house. You agree both before work begins in Brent. Ring 07472 424 226 and we will explain how bathroom renovation is matched to the finishes already present in an NW6 home today.
It comes down to proper tanking. Before tiling, we apply a full waterproof membrane to the floor and shower walls, form the correct falls to the drain and fit a reliable waste, so water cannot reach the structure or the flat beneath. We also fit good mechanical ventilation to control condensation. This protects you, your downstairs neighbour and your relationship with the managing agent.
Yes, across Brent and much of North West London. Bathroom renovation takes us to Wembley and the surrounding areas regularly, and a property just outside Kilburn is no harder to service than one at NW6. GS Renovation will say plainly if distance makes a job impractical. Email info@gsrenovationltd.co.uk with the address and we will tell you either way. Nothing is owed for asking or for the survey. Aftercare is no harder a few streets further out.
