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.
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
We price each Kilburn project individually, because the cost of bathroom renovation depends on far more than floor area. After a free survey you receive a clear written breakdown with no hidden extras. Call 07472 424 226 or email info@gsrenovationltd.co.uk. 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.
A straightforward Kilburn project can be done in a couple of weeks, while a larger bathroom renovation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.

Yes. Bathroom electrics in Kilburn 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 Kilburn's homes are mansion-block and period-flat properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as leasehold consents, shared structure and sound insulation between flats, so the result suits the building and meets building control.
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, Kilburn is one of our core areas. We work on every street and the NW6 area and across the wider North West London, so wherever your home is, call 07472 424 226 and we will confirm we can help.
