Waterproofing and wet rooms in Merton

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.

Space-saving layouts for Merton period homes

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.

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.

FAQ

Frequently Asked Questions about Bathroom Renovation Merton

How much does bathroom renovation cost in Merton?

The cost of bathroom renovation in Merton depends on the size of the property, the specification and the scope of work. GS Renovation provides free, detailed and itemised quotations for every Merton project. Call 07472 424 226 or email info@gsrenovationltd.co.uk for a no-obligation estimate. 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.

How long does bathroom renovation take in Merton?

A straightforward Merton project can be done in a couple of weeks, while a larger bathroom renovation with structural work runs longer. We set out a realistic, stage-by-stage programme before we begin so there are no surprises.

Why choose GS Renovation for bathroom renovation in Merton?

GS Renovation's team brings over 30 years of hands-on experience to bathroom renovation and wider building work across Merton and the surrounding area. We offer free quotes, a dedicated project manager, full insurance, building control compliance where required, and comprehensive aftercare.

Do I need building regulations for a bathroom in Merton?

Yes. Bathroom electrics in Merton 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.

Do you work on Victorian and Edwardian terraced homes in Merton?

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.

Can you fit a walk-in shower or wet room in my small Merton bathroom?

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.

Do you cover all of Merton?

Absolutely. Our team works right across Merton and the SW19 area and neighbouring parts of South West London. Get in touch on 07472 424 226 to check coverage for your address.
