Luxury bathroom and wet-room refurbishment in Epsom. Trusted, professional, 30+ years' hands-on experience.
Bathrooms fail at the joints between trades, so we do not split them. The same team handles the strip out, any joist or structural work, the first fix plumbing and electrics, the tanking, the tiling and the second fix. That gives you one point of contact and one firm answerable for whether the shower tray still drains in five years.

Those homes are recent by Epsom standards. In the Horton and Manor Park area, Valuation Office Agency figures for 31 March 2025 record 780 of 4,280 dwellings with a known build period as built between 2000 and 2008. That reflects the redevelopment of the former hospital sites.
In a flat, the building sets the constraints before the design does. Soil stack positions, floor build ups and acoustic layers are already fixed, and lease consent, delivery windows and waste removal are set by the managing agent rather than by the builder. We survey those before we price, so the programme we give you is one the building will allow. Moving a WC may still be possible, but it is a drainage design question first and a tiling question second.
Thames Water owns part of it and you own the rest. Thames Water is the sewerage undertaker for Epsom and Ewell, responsible for the main sewer in the road and the lateral drains that lead to it. A drain serving one property only is the owner's responsibility. That line matters when a bathroom moves, because the new run has to reach an existing connection with the right fall.
Getting the fall right is what keeps a bathroom working. We set out the waste runs at first fix, test them before anything is boarded, and tank the wet areas before tiling rather than relying on grout to hold water back. New or altered drainage is Building Regulations work, and we coordinate the application and the inspections where the job needs them.
The order of a bathroom is what decides whether it lasts, so we keep it in one pair of hands. Strip out, joists and structure, first fix plumbing and electrics, tanking, tiling and second fix all run to one programme with the same team. That gives you one point of contact and no gap where a problem can become nobody's. Building control applications and inspections are coordinated where the work needs them.

FAQ
Usually because they are not quoting the same work. One builder includes making good and the Epsom and Ewell Borough Council application, another leaves both out, and the bathroom renovation figures for the same Epsom house then look nothing alike. GS Renovation itemises every line for the KT17 property so you can see what is in and what is missing. Compare the scope before the totals, and ring 07472 424 226 if another Epsom quotation for bathroom renovation puzzles you. 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.
In an Article 4 area, check the schedule before anything is routed. Eleven heritage Article 4 directions are in force in Epsom and Ewell, and each lists controlled works elevation by elevation. The Worple Road schedule covers front extensions, roof material changes, front rooflights and the demolition of a chimney stack. New pipework or a terminal on a front elevation in a conservation area is worth putting to the council first. Running it at the rear avoids the question.
Yes. Epsom and Ewell's notifiable stages include the main structural element whose failure would be significant, and floor timbers are one of the council's own examples. Notching or trimming joists for a waste run, or loading them with a stone floor, reaches that stage. Valuation Office Agency figures record 11,720 of the borough's 32,980 dwellings with a known build period as built between 1930 and 1939. What joists of that age will take is established by the engineer we appoint.
Elmbridge Building Control Services Ltd deals with them. That company has managed the building control service for Epsom and Ewell since 1 April 2023, and the council directs applications, site inspections and structural details to it on 01372 303145. The notifiable items include new electrical circuits, altered drainage, changes to ventilation and any new window opening. Replacing a suite in the same positions is not one of them. We separate the two at quotation stage.
Where an existing drainage connection can be reached at a workable gradient. That is settled by survey, not by the floor plan. Valuation Office Agency figures for 31 March 2025 record 550 of 4,010 dwellings in the Epsom Town area with a known build period as built before 1900. Drainage laid for a house of that age was not planned around an upstairs bathroom, so we survey the run, its vent and its access points before a layout is drawn.
