Luxury bathroom and wet-room refurbishment in Harlesden. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refits bathrooms and en-suites throughout Harlesden, making the most of the often tight spaces in NW10's Victorian and Edwardian terraces. With over 30 years in Brent, we handle the waterproofing, drainage, tiling, heating and every trade in between, delivering wet rooms, walk-in showers and family bathrooms that last.

In these older NW10 terraces, bathrooms often sit over the rear closet wing or in a converted return, on timber floors that move and older masonry that needs care. Getting the waterproofing right matters more than any finish. We fully tank wet areas and shower zones before tiling, so water is kept out of the structure and there are no leaks into the rooms below, whatever the layout of the house.
We upgrade the drainage and ventilation at the same time, because period bathrooms are prone to poor airflow and damp. New soil and waste runs are set to the right falls, and extraction is fitted to clear moisture properly. Underfloor heating can go under the tiles to warm the room and help it dry, a real benefit in the solid-floored areas of these Harlesden terraces.
Space is the constant challenge in Harlesden bathrooms, whether it is a narrow main bathroom over the closet wing or a new en-suite carved out of a bedroom corner. We plan the layout carefully, choosing compact sanitaryware, walk-in showers and wall-hung units that free up floor area and light, so even a small room in an NW10 terrace feels open rather than cramped.
A walk-in shower or full wet room suits these homes well, removing the tray lip and making a small space feel larger, provided the tanking and drainage are done properly. We tile floors and walls, set out the lighting and finish to a high standard. Bathroom electrics are notifiable under building regulations and get certified, and no planning permission is needed for an internal refit.
Harlesden homeowners choose GS Renovation because bathrooms in period terraces live or die on the waterproofing and drainage beneath the tiles. We tank properly, sort the falls and ventilation, and finish to a high standard in the tight spaces of these NW10 homes. Thirty years in Brent means the hidden work is done right, not just the surface.

FAQ
Ask three builders in Brent and you will get three different numbers for bathroom renovation, usually because they have scoped three different jobs. We price the NW10 property after a survey and set out labour, materials, approvals and making good line by line. A Harlesden homeowner can then see where any difference actually sits. GS Renovation puts all of it in writing. Ring 07472 424 226 and GS Renovation will arrange a free survey at your NW10 property. 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.
Book the survey now and decide later, because that costs nothing. It gives GS Renovation the information to programme bathroom renovation at your NW10 home and gives you a real date rather than an estimate. Demand across Harlesden and Brent varies with the season. We will always tell a North West London client honestly when the next slot genuinely is. The survey at NW10 costs nothing and commits a Harlesden homeowner in Brent to nothing.
Accountability, mainly. The person who surveys your NW10 property is answerable for what happens on the Harlesden site, and bathroom renovation is delivered by our own team rather than sold on. GS Renovation is fully insured, coordinates Brent Council building control, and gives you a five year guarantee on installations. The 31 MyBuilder reviews behind our 4.9 rating are public. Ask on 07472 424 226 for Brent addresses to look at. The five year guarantee covers installations at NW10.
Usually yes, and it is one of the commonest upgrades we make in Harlesden. The constraints are the soil stack route and the floor structure, both checked at survey, and the electrics need Part P certification through Brent Council.
Original features are an asset, and we treat them that way. Before bathroom renovation starts at a Harlesden address, GS Renovation agrees what is being kept, protects it physically, and plans the NW10 sequence accordingly. Making good afterwards matches the existing profiles. That care is part of the quotation, not an extra billed later in Brent. Ask on 07472 424 226 how bathroom renovation is planned around the original detail at an NW10 property instead.
Yes. A walk-in wet room suits the tight bathrooms in these NW10 terraces, removing the tray lip so a small room feels larger. The key is proper tanking and correctly graded drainage, especially over the timber floors above the closet wing. We waterproof fully, set the falls, add ventilation and underfloor heating, and tile to finish. No planning permission is needed for an internal refit.
Yes, Wembley is well within the patch. Bathroom renovation runs across Harlesden, the surrounding Brent and the areas between them, so neither address is a stretch. GS Renovation charges nothing for the survey at an NW10 property or anywhere else nearby. Ring 07472 424 226 and we will confirm availability for both. Building control is coordinated with Brent Council on each of them. Small jobs at either address are quoted on exactly the same basis.
