Luxury bathroom and wet-room refurbishment in Brentford. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms throughout Brentford, from en-suites in riverside apartments to family bathrooms in TW8 terraces and warehouse conversions. With over 30 years of experience, we handle waterproofing, drainage, tiling, heating and ventilation to a proper standard, so your new Brentford bathroom performs as well as it looks and protects the flats and rooms around it.

In Brentford's converted and new-build apartments, a bathroom sits above someone else's home, so getting the waterproofing right is not optional. We tank the walls and floor properly before tiling, form falls to the drainage, and test the installation so there is no risk of water reaching the flat below. Correct tanking and a well-designed wet room or walk-in shower are the difference between a bathroom that lasts and one that causes disputes with neighbours.
Ventilation and drainage need equal care in a flat. We install extraction that clears moisture rather than trapping it, run new waste to existing stacks correctly, and finish with tiling, underfloor heating and considered lighting. Any notifiable electrical work is certified under building regulations. Throughout, we coordinate with the managing agent on access and working hours so a bathroom refurbishment in a TW8 block goes smoothly for everyone in the building.
Period terraces in Brentford often have awkward, dated bathrooms squeezed into tight footprints. We are practised at making the most of small spaces, planning layouts that fit a proper shower, basin and WC without feeling cramped, and adding an en-suite where the room allows. Wall-hung fittings, walk-in showers and clever storage all help a compact Brentford bathroom feel generous.
Behind the finish, the fundamentals still matter. We tank wet areas, upgrade drainage and ventilation, and can lay underfloor heating for warmth underfoot in a solid-floored terrace. Tiling is set out carefully so the finished room reads as considered rather than compromised, and electrics are certified under building regulations. The result is a bathroom that suits the age of the house while working comfortably for a modern household.
Brentford homeowners choose GS Renovation because a bathroom in a flat or terrace has to be watertight, well drained and properly ventilated, not just nicely tiled. We tank thoroughly, get the drainage and extraction right, certify electrics under building regulations, and coordinate with managing agents in TW8 blocks. Over 30 years of West London experience means your bathroom is built to last.
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!

Yes. Bathroom electrics in Brentford 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 Brentford's homes are warehouse-conversion and new-build properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as concrete or steel frames, building-management rules and modern services, so the result suits the building and meets building control.
A like-for-like bathroom refurbishment usually does not need planning permission or a freeholder's licence, but moving the bathroom or altering drainage often does, so check your lease. Because your flat sits above another home, thorough tanking and correct drainage are essential. We waterproof properly, coordinate access with the managing agent, and certify notifiable electrical work under building regulations.
