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.

FAQ
You get a variation, in writing, before anything else happens. The commonest cause on a bathroom renovation job is a homeowner upgrading a finish once the KT1 space is open, which is entirely reasonable and easy to price. GS Renovation also re-checks the programme so a Kingston upon Thames project does not quietly slip. The Kingston Council inspections are rebooked where needed. Ring 07472 424 226 to hear how that runs on a KT1 project in Kingston upon Thames. 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.
Structure first, then services, then finishes, with the Kingston Council inspections fixed between them. That sequence is what stops trades undoing each other on a bathroom renovation job at a KT1 address, and it is written into the programme GS Renovation issues with the quotation. Your Kingston upon Thames project is updated against it weekly. Nothing is concealed anywhere in Kingston upon Thames before it has been inspected. Ask GS Renovation on 07472 424 226 for the written KT1 programme before you commit.
Openly, because the alternative shows up at handover. A bathroom renovation project in a Kingston upon Thames home occasionally uncovers wiring, timber or drainage nobody could have seen at KT1, and GS Renovation treats that as a variation to agree rather than a chance to add cost. Kingston Council is notified where the change affects approved work. Nothing proceeds without your say-so. Ask for Kingston upon Thames references on that point. The engineer's fee appears on the KT1 quotation in Kingston upon Thames.
The electrical element is, under Part P, and it must be certified. Wet systems tie into the heating and engage Part L. We install and test underfloor heating before tiling at your KT1 property, and the certification goes through Kingston Council with the rest of the work.
Different in approach, not in standard. The work still has to satisfy Kingston Council and the engineer's design, but bathroom renovation in a Victorian and Edwardian terraced Kingston upon Thames property is sequenced to protect what is already there at KT1. GS Renovation agrees with you beforehand which features are being kept. That conversation is what prevents regret afterwards in Kingston upon Thames. Ring 07472 424 226 and we will explain which features can be kept during bathroom renovation at your KT1 home.
Usually yes. The main constraints are reaching the soil stack for drainage and finding room for a compact walk-in shower and wall-hung fittings. In many Kingston terraces we take space from a large bedroom or a closet wing. No planning permission is needed for an internal en-suite, though the electrics are notifiable under building regulations, which we certify.
Yes, both. Bathroom renovation in a KT1 flat brings the lease and the freeholder's consent into it, which is the main practical difference from a Kingston upon Thames house, and GS Renovation will explain what applies before any design work. Building control still goes through Kingston Council. Ring 07472 424 226, describe the block, and we will tell you what is involved. The survey across Kingston upon Thames is free either way. The freeholder's licence to alter comes first at KT1.
