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.
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!
