Luxury bathroom and wet-room refurbishment in Twickenham. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms and en-suites across Twickenham, fitting new suites, wet rooms and walk-in showers into the Victorian and Edwardian terraces of TW1. With over 30 years in the Richmond upon Thames borough, we take care of the waterproofing, drainage, tiling and finish so the room performs as well as it looks.

A bathroom only lasts if the waterproofing is right, which matters especially in Twickenham's older terraces with their suspended timber floors. We tank the walls and floor properly before tiling, so wet rooms and walk-in showers stay watertight for the long term rather than leaking into the joists below. Getting the drainage falls and ventilation right at this stage is what prevents damp and rot later.
Falls to the drain, a well-sized waste and proper extraction all get designed in from the start, not bolted on at the end. Where a shower sits over a timber floor, we reinforce and prepare the substrate so the tiling does not crack or move. Underfloor heating is a popular addition in these period bathrooms, warming a room that can otherwise feel cold, and we lay it under the tiled floor as part of the build.
Bathrooms in TW1 terraces are often tucked into the rear closet wing or carved out of an awkward corner, so every centimetre counts. We plan layouts that make a small room work, using a walk-in shower instead of a bath, a wall-hung basin and concealed cistern, and clever storage. The aim is a bathroom that feels generous even when the footprint is genuinely tight.
Adding an en-suite to a Victorian bedroom brings its own challenges, mainly getting waste and water to a room that never had plumbing. We work out the pipe runs, boxing them in neatly and keeping the drainage falls correct, so the new en-suite functions properly without spoiling the room. Across Twickenham and nearby Teddington and Kew, this is one of the most popular ways owners add value to a period house.
Twickenham owners choose GS Renovation for bathrooms because we get the parts you cannot see right, the tanking, the falls, the drainage and the ventilation, as well as the tiling and finish you can. One team fits the whole room, working cleanly in an occupied TW1 home. With 30+ years in the borough, we build period bathrooms that stay watertight and look the part.

FAQ
Not a real one, no. We can explain on 07472 424 226 how bathroom renovation is usually approached in a Twickenham home and what tends to move the cost, but the TW1 property has to be seen before GS Renovation commits anything to paper. Builders who quote blind across Richmond upon Thames are the ones who revise later. Email info@gsrenovationltd.co.uk with the address and we will arrange a time. The TW1 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.
Yes. The team on your bathroom renovation project stays on it until the TW1 work is finished, which is the whole reason the Twickenham programme is predictable. GS Renovation does not open several Richmond upon Thames sites and rotate between them, and that is the commonest complaint homeowners have about builders. One named project manager sees the job through to sign-off. Ask for Richmond upon Thames references and check how a TW1 project actually ran in Twickenham.
Because you get one accountable team rather than a chain of subcontractors. GS Renovation is the contractor carrying out bathroom renovation at your TW1 property, with a named project manager from survey to handover and full insurance throughout. We are rated 4.9 from 31 reviews on MyBuilder, and the Richmond Council paperwork is handled for you. That applies across Twickenham and the wider Richmond upon Thames. Ring 07472 424 226 and ask for TW1 references. Insurance details follow on info@gsrenovationltd.co.uk request.
Usually yes, and it is one of the commonest upgrades we make in Twickenham. The constraints are the soil stack route and the floor structure, both checked at survey, and the electrics need Part P certification through Richmond Council.
Comfortably. What bathroom renovation demands in an older Twickenham home is investigation first, because aged materials and irregular dimensions change both method and programme at a TW1 property. GS Renovation prices that from experience rather than guarding against it. Ring 07472 424 226 and we will talk through what your Richmond upon Thames house is likely to need. The TW1 survey is free, and the written Twickenham quotation for bathroom renovation follows only a few days later.
Yes. Timber floors are common in Twickenham terraces and a wet room works well on them provided the preparation is right. We reinforce the substrate, form the falls to the drain and fully tank the area before tiling, so water cannot reach the joists. Good extraction is fitted too. Bathroom electrics are notifiable under building regulations, which we handle as part of the job.
Anywhere in the area, and there is no minimum job size. Bathroom renovation enquiries reach GS Renovation from across Twickenham and South West London, and each gets a free survey at the TW1 property and a written quotation afterwards. Building control is coordinated with Richmond Council where the work requires it. Email info@gsrenovationltd.co.uk to get started. Nothing is owed whether you proceed or not. Small jobs at a TW1 address are just as welcome here.
