Bathroom Renovation Bexley

GS Renovation renovates bathrooms across Bexley, fitting family bathrooms, en-suites and wet rooms into the 1930s semis and interwar homes of Bexleyheath, Sidcup and Welling. Working throughout DA5, DA6, DA7 and SE2, we handle the waterproofing, drainage, tiling and heating in one job. We build bathrooms that stay watertight for years.

In Bexley, 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 Bexley: 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 Bexley 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.

Wet rooms and en-suites in Bexley semis

Fitting a second bathroom into a 1930s Bexley semi usually means borrowing space, from a corner of a bedroom for an en-suite to the box room above the stairs. We work out where the soil pipe and drainage can run, add proper mechanical ventilation to clear the moisture, and tank the walls and floor before a single tile goes on. Getting the waterproofing right first is what keeps a period house dry.

Wet rooms suit these houses well, doing away with the tray and giving a level, walk-in shower that is easy to use and easy to clean. On the timber suspended floors common in interwar semis we reinforce and prepare the deck, lay a bonded waterproof membrane, and set the falls so water runs to the drain. Underfloor heating beneath the tiles takes the chill off a bathroom that runs cold.

Housing in Bexley

The stock in Bexley runs to roughly 101,760 dwellings, 27% of them flats and 73% houses, built 11% before 1919, 41% between 1919 and 1939 and 48% after 1945. Semi-detached houses make up 36% of homes here, and a semi in Bexley can vent its bathroom through the flank.

Bexley bathrooms, shared houses and the small HMO direction

When a Bexley house is prepared for letting by the room, en-suites are usually part of the plan. Bexley's borough-wide Article 4 Direction on small houses in multiple occupation came into force on 24 September 2017. That puts the change from a family house to a small shared house under planning control across the borough, so the planning question comes before the bathrooms are designed. Build the en-suites first and a planning refusal can leave you with a house laid out for a use it is not allowed. Get planning permission in place before the first soil pipe is moved.

The layout of a Bexley house decides where a new bathroom can go. 41% of homes here were built between 1919 and 1939, and a house of that age may have its bathroom and a separate WC at the back, over the kitchen, with the soil pipe on the rear wall. An en-suite at the front of the house then needs a new waste route across the joists, and the joists set how far it can fall. The structural engineer we appoint checks any notching or trimming before the joists are cut.

Watertight family bathrooms across Bexley

The main family bathroom in a Bexley semi is often the original small room, tiled decades ago and long past its best. We strip it back, renew the concealed plumbing and waste, and re-plan the layout so a bath, a decent shower and storage all fit. Space-saving fittings, a wall-hung basin and a shower over the bath make the most of the modest footprint these interwar rooms were built with.

Behind the tiles, the detail matters. We use tanking and quality waterproofing around the wet zones, seal the junctions properly and ventilate the room so the damp that plagues older Bexley houses does not take hold. New circuits, such as a shower supply, and circuit changes near the bath or shower are notifiable under Part P and certified by a registered electrician or notified to building control. The result is a warm, dry, easy-to-clean bathroom finished to last.
