Bathroom Renovation Kingston

GS Renovation fits bathrooms and en-suites throughout Kingston upon Thames, working within the tight footprints of its flats, semis and Victorian and Edwardian terraces, where a closet wing often becomes the family bathroom. We handle the waterproofing, services and finish together.

In Kingston upon Thames, 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 Kingston upon Thames: 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 Kingston upon Thames 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.

Waterproof wet rooms in Kingston homes

A wet room or walk-in shower only lasts if the waterproofing is done properly, and in a Kingston house that often means suspended timber floors that move. We tank the floor and walls fully, form the falls to the drain and bond the tiling to a sealed background, so water goes where it should and nowhere else. Ventilation is designed in from the start, because older homes hold damp, and good extraction protects both the finish and the fabric around it.

Bathrooms do not need planning permission, but moving soil and waste pipes takes care in a period house, and new circuits or changes around the bath or shower are notifiable under building regulations. We reconfigure drainage where a layout changes, run new supplies neatly, and have the circuits for shaver points, heated towel rails and underfloor heating certified by a registered electrician. Warm tiled floors make a real difference in the cooler back rooms and closet wings of a Kingston terrace, and we lay the heating mats under a properly built floor.

A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Kingston Council, and doing it without consent is a criminal offence.

Forming a new bathroom in a Kingston upon Thames home

For building control, replacing a bathroom where one already stands is not the same as creating one. Kingston treats the formation of a new bathroom or WC as its own item, charged the same for full plans or building notice and at a higher rate for regularisation. In a Kingston upon Thames house that catches the en-suite cut from a bedroom, a second bathroom in the box room and a shower room in a converted garage. Each needs a waste route at a proper fall to the soil stack, extraction to outside and, where it adds weight, a check of the joists by the structural engineer we appoint.

42% of homes in Kingston upon Thames are flats, and a new bathroom in a flat may be proposed over the living room or bedroom of the flat below. Check the lease first, since some leases forbid wet rooms over a neighbour's habitable room or need the freeholder's consent. Where it goes ahead, the whole floor is waterproofed, not just the shower area, and the new waste joins the stack at a point the freeholder agrees. Registering the room before work gives you the certificate a buyer's solicitor will want, which regularisation later provides only at the higher charge and with the floor opened up.

Space-saving en-suites across Kingston terraces

Fitting an en-suite into a Kingston bedroom, or a family bathroom into a narrow closet wing, is a puzzle of millimetres. We plan the layout around the door swing, the window and the soil stack, choosing a compact walk-in shower, wall-hung sanitaryware and slimline units to keep the floor visually clear. Where the ceiling slopes under the rear roof, we set the shower and basin where the head height allows, so even an awkward Victorian space works hard and feels bigger.

One team fits the whole bathroom, so there is no waiting between plumber, tiler and electrician. We strip out, adjust the structure and services, tank, tile, install and finish to a single programme, keeping the one working bathroom in the house usable for as long as we can. The result is a watertight, well-ventilated room with warm floors and clean tiling, built to cope with daily family use in a Kingston home for years to come.
