Luxury bathroom and wet-room refurbishment in Isleworth. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates bathrooms, en-suites and wet rooms across Isleworth, working within the tight footprints typical of TW7's Victorian and Edwardian terraces. With more than 30 years in Hounslow borough, we handle the waterproofing, drainage, tiling, heating and ventilation properly, so your new bathroom in a bay-fronted period home looks beautiful and stays dry for years.

A wet room or walk-in shower suits the awkward spaces found in Isleworth terraces, whether that is a former box room, a landing corner or the end of a closet wing. The key is getting the waterproofing right, so we tank the floor and walls fully before a single tile goes on, form the falls to the drain accurately, and bond the membrane into the tanking. Done properly, this prevents the leaks that plague poorly built showers.
Older terraces in TW7 often have original drainage that was never designed for a modern shower, so we upgrade waste runs and soil connections to cope with the flow. Good extract ventilation is essential in these solid-walled homes, where damp lingers, so we fit humidity-controlled fans that clear moisture before it reaches the plaster. Underfloor heating warms the tiled floor and helps the room dry quickly between uses, which matters in a period house.
Adding an en-suite to an Isleworth bedroom, or squeezing a family bathroom off a narrow landing, is all about clever planning. We use compact and wall-hung sanitaryware, sliding or pocket doors, and concealed cisterns to free up floor space in rooms that were never designed with bathrooms in mind. Careful setting out around the joists, the soil stack and any chimney breast lets us fit a proper shower, basin and WC into a surprisingly small footprint.
Bathroom electrics fall under building regulations, so lighting, shaver points, heated towel rails and extractor fans are all installed to the correct zones and certified. We finish with fully tiled or panelled walls, sealed junctions and quality brassware, choosing tiling that suits the character of your Victorian or Edwardian home. From a single en-suite to a full family bathroom, everything is handled by one team, so the plumbing, waterproofing, tiling and electrics all tie together neatly.
Isleworth homeowners choose GS Renovation for bathrooms because we get the hidden work right: full tanking, proper falls, upgraded drainage and effective ventilation, not just attractive tiling. That is what keeps a bathroom in a solid-walled TW7 terrace dry and damp-free. With 30+ years across Hounslow borough and one team for every trade, your bathroom is built to last and certified throughout.
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
Every Isleworth project is priced on its own merits, as the cost of bathroom renovation varies with the size, specification and condition of the home. We give a clear, itemised quote up front with no obligation. Call 07472 424 226 for an estimate tailored to your 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.

No. Fitting or reconfiguring a bathroom or en-suite inside your Isleworth home does not need planning permission. However, the electrical work is notifiable under building regulations, so it must be installed and certified correctly, and new drainage or waste connections must also comply. We handle those approvals for you. Planning permission only becomes relevant if the bathroom forms part of an extension to the property.
