Luxury bathroom and wet-room refurbishment in Chiswick. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refits bathrooms across Chiswick, fitting modern wet rooms, en-suites and family bathrooms into the compact spaces of W4's Victorian and Edwardian terraces. With over 30 years locally, we handle the waterproofing, drainage, tiling, heating and ventilation in-house, so a bathroom in a period home is watertight and built to last.

A leaking bathroom in a Chiswick terrace can travel into solid walls and down onto the room below, so we treat waterproofing as the foundation of every job. We fully tank wet rooms and walk-in showers before a tile is laid, form the falls to the drain correctly, and upgrade drainage and extraction so moisture leaves the room rather than sitting in old plaster. In period homes that difference protects the fabric of the house.
Because W4 bathrooms are often carved out of a closet wing or a small return, layout is everything. We plan space-saving arrangements that fit a proper shower, basin and WC into a tight footprint, add underfloor heating to free up wall space, and choose tiling that suits the age of the house. The result is a bathroom that feels generous despite the modest dimensions typical of these terraces.
Many Chiswick projects add an en-suite off a main bedroom or reconfigure the existing bathroom over the closet wing to work harder for a growing family. We handle the new soil and waste connections, the concealed plumbing and the mechanical ventilation needed to keep an internal or period room dry. Where an en-suite sits above a habitable room, we detail the waterproofing and pipework so there is no risk of hidden leaks later.
Bathroom electrics, from the extractor and lighting to any electric underfloor heating and shower, are notifiable under building regulations, and we make sure that work is done and certified correctly. We finish with quality tiling, sanitaryware and heated towel rails, working tidily in an occupied home. In W4 terraces where every square metre counts, thoughtful layout and proper services turn an awkward space into a bathroom that works day to day.
Chiswick homeowners choose GS Renovation because we get the hidden work right, full tanking, drainage, ventilation and certified electrics, before the tiles ever go on. We know how to fit wet rooms, en-suites and family bathrooms into the tight closet-wing spaces of W4 terraces, and thirty years locally means a watertight result that protects the house.

FAQ
Not a real one, no. We can explain on 07472 424 226 how bathroom renovation is usually approached in a Chiswick home and what tends to move the cost, but the W4 property has to be seen before GS Renovation commits anything to paper. Builders who quote blind across Hounslow are the ones who revise later. Email info@gsrenovationltd.co.uk with the address and we will arrange a time. The W4 survey carries no obligation of any kind. 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.
Rarely, in our experience. The Hounslow Council element of bathroom renovation on a Chiswick home is predictable once you know which route applies, and GS Renovation advises whether a building notice or full plans approval suits your W4 property. Full plans takes longer but removes uncertainty before work starts. Either way the inspections are booked ahead across Hounslow. Ring 07472 424 226 and we will explain which of the two applies to a W4 property in Chiswick.
Enough to know where the problems hide in a W4 property before quoting. Bathroom renovation in Victorian and Edwardian terraced housing throws up variation that a modern estate does not, and 30 years of hands-on experience is what turns that into an accurate Chiswick figure rather than a cautious one. GS Renovation has been incorporated since 2023. The experience behind it is considerably older. Ask on 07472 424 226 about Hounslow projects. References near W4 are given as addresses, not testimonials.
The electrical element is, under Part P, and it must be certified. Wet systems tie into the heating and engage Part L. We install and test underfloor heating before tiling at your W4 property, and the certification goes through Hounslow Council with the rest of the work.
That stock is our core work. Bathroom renovation in the streets around W4 is familiar enough that GS Renovation knows which parts of a Chiswick house tend to hide problems, and prices for them instead of discovering them later. Hounslow Council building control is coordinated by us throughout. Ask for references anywhere in Hounslow. Ask on 07472 424 226 what bathroom renovation typically uncovers in a Chiswick house near a W4 address, and what it costs.
Yes. The compact bathrooms in W4 terraces, often over the closet wing, suit a walk-in wet room that uses the whole floor efficiently. We fully tank the space, form the falls to the drain, upgrade drainage and ventilation, and add underfloor heating to save wall space. The electrics are notifiable under building regulations, so we ensure that side is certified as part of the job.
Yes, boundaries are not something we price against. Bathroom renovation runs across Hounslow and into West London, so an address on the edge of Chiswick or over towards Brentford is no harder to service. GS Renovation will say plainly if travel makes it impractical. Ring 07472 424 226 with the W4 postcode and we will confirm. The survey that follows is free and carries no obligation. Aftercare is no more difficult a few streets further out.
