Luxury bathroom and wet-room refurbishment in Kingston upon Thames. Trusted, professional, 30+ years' hands-on experience.
GS Renovation fits bathrooms and en-suites throughout Kingston upon Thames, working within the tight footprints of its Victorian and Edwardian terraces and the closet wings that so often become the family bathroom. With more than 30 years across KT1, KT2, KT3, KT5 and KT6, we handle the waterproofing, services and finish together.

A wet room or walk-in shower only lasts if the waterproofing is done properly, and in a Kingston terrace that usually 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 period 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 the electrics are notifiable under building regulations. We reconfigure drainage where a layout changes, run new supplies neatly, and certify the circuits for shaver points, heated towel rails and underfloor heating. 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.
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 period home for years to come.
Kingston homeowners choose GS Renovation for bathrooms because we get the parts you cannot see right, the tanking, the falls, the drainage and the ventilation, before the tiling ever goes on. With 30+ years across KT1 to KT6, we make small period spaces work, certify the electrics under building regulations and leave a room that stays watertight.
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!
