Luxury bathroom and wet-room refurbishment in Merton. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refurbishes bathrooms throughout Merton, from compact family bathrooms in Wimbledon terraces to en-suites in larger homes near Morden and Mitcham. With more than 30 years of experience in SW19, SW20, CR4 and SM4, we handle the waterproofing, drainage, tiling and heating so period-home bathrooms are dry, warm and built to last.

Proper tanking is the part of a bathroom you never see and cannot skip. In Merton's solid-wall terraces we fully waterproof the walls and floor before a single tile goes on, which matters most in wet rooms and walk-in showers where water is not contained by a tray. Done correctly, tanking protects the joists and the ceiling of the room below.
Drainage and ventilation take extra thought in a Victorian or Edwardian house, where the bathroom often sits in the rear closet wing with limited fall to the soil pipe. We set the pipework to run cleanly, fit extraction that clears moisture properly, and finish with tiling and underfloor heating so the room stays warm on a cold Wimbledon morning.
Bathrooms in Merton terraces are frequently tight, carved out of a closet wing or a small return bedroom over the years. We plan layouts that make every centimetre count, using walk-in showers, wall-hung units and considered positioning of the basin and WC so the room feels larger than its footprint suggests without cramming fittings together.
For growing families in SW19 and SW20, adding an en-suite to the main bedroom is a popular way to ease the morning rush. We assess where the drainage and water supply can reach, then build a compact, fully tanked en-suite that suits the proportions of the period house rather than fighting against them.
Merton homeowners choose GS Renovation because a lasting bathroom depends on the waterproofing and drainage beneath the tiles, not just the finish. We tank properly, sort ventilation in awkward period layouts, and complete the tiling, heating and plumbing in one coordinated job, with 30+ years across SW19, SW20, CR4 and SM4.
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. A large share of Merton's homes are Victorian and Edwardian terraced properties, and we renovate them regularly. We plan each bathroom renovation around their particular characteristics, such as solid brick walls, rear closet wings, side returns and original period features, so the result suits the building and meets building control.
Yes. Even in the tight bathrooms of Merton's period terraces, a walk-in shower or wet room often uses the space better than a bath. The key is full tanking and correct drainage falls, especially over the room below. We waterproof thoroughly, sort the ventilation, and plan a layout that makes a compact room feel open.
