Bathroom Renovation Battersea

GS Renovation renovates bathrooms and en-suites across Battersea, working within the tight rooms of SW11's flats and fewer period terraces. We handle waterproofing, drainage, tiling, heating and ventilation together, turning dated or cramped bathrooms into properly tanked, hard-wearing wet rooms and walk-in showers.

In Battersea, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Battersea: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Battersea home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Waterproofing and wet rooms in Battersea

A bathroom in a period Battersea house sits on suspended timber floors above rooms you do not want to flood, so waterproofing is not optional. We tank the walls and floor before tiling, forming falls to the drain and sealing every junction, which is what makes a proper wet room or walk-in shower reliable over years of daily use. Cut corners here and the failure shows up as damp on the ceiling below.

Ventilation and drainage matter just as much on these older SW11 homes. Original soil pipes and vents were rarely designed for power showers, so we upgrade extraction and reroute waste where needed to keep the room dry and free of condensation. The result is a bathroom that looks the part and, more importantly, stays watertight in a house that may be a hundred and twenty years old.

Housing in Battersea

Roughly 33,740 dwellings sit on the valuation list for Battersea. 9% are houses and 91% flats, and by age 19% predate 1919, 4% are interwar and 76% post-war. A bathroom in a flat in Battersea sits over a neighbour's ceiling, so tanking comes first, which matters here because most homes are flats.

Bathrooms in Battersea's newer apartment blocks

47% of homes in Battersea were built in 2000 or later, so a bathroom renovation here is often in a flat built this century. In those blocks the bathroom usually sits on a concrete slab, the drainage runs to a riser shared with the flats above and below, and the extract fan connects to a duct the building provides. The layout is therefore fixed by the building more than by the room. A shower moved to the far wall needs a fall to the riser the slab may not allow, and a new fan outlet cannot be cut through the facade without the freeholder's consent and a planning application.

What works in a newer Battersea flat is a renovation that keeps the waste positions and the extract connection, and changes almost everything else. A wet room can go in where the tray was, a wall-hung toilet can replace a close-coupled one on the same outlet, and a larger basin can use the same waste. Before any design, we ask the managing agent for the drainage drawings and the waterproofing specification the block was built to, because a new tanking system has to join the building's own detail at the door threshold and the riser.

Space-saving bathrooms for Battersea homes

Space is the recurring challenge in Battersea, where a flat's bathroom is often an internal room by the soil stack and a terrace's sits in a rear closet wing or on a half-landing. We plan layouts that make every inch count, using walk-in showers instead of bulky enclosures, wall-hung sanitaryware, and slim underfloor heating so no space is lost to radiators. Careful design makes an awkward room feel generous.

En-suites are increasingly popular in SW11, borrowing a slice from a bedroom or a bulkhead over the stairs to add a second bathroom. We handle the drainage runs and the tiling ourselves, with the notifiable electrics certified by a registered electrician, and finish with heating and lighting that suit the home. In a flat, the licence to alter and the route to the soil stack decide whether it can be done.

• Pressure and leak testing before any tiling starts
• Wall and floor tiling in stone, porcelain or mosaic
• Bespoke vanity units and storage
