Bathroom Renovation Epsom
Bathroom and wet-room refurbishment in Epsom, tanked, plumbed and tiled by one team.
- Rated 4.9 from 31 reviews on MyBuilder
- Guide from £6,000 (London-derived)
- Free design visit, itemised quote
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.
For Epsom, on London-derived ranges a full bathroom refit typically costs £6,000 to £20,000 or more; Surrey work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Epsom: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

Bathrooms in the newer housing at Horton and Manor Park
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.
Housing in Epsom
About 16,290 homes are listed for Epsom, and the mix is 65% houses to 35% flats, with 60% built after 1945, 23% in 1919 to 1939 and 15% earlier. Semi-detached houses make up 22% of homes here, and a semi in Epsom can vent its bathroom through the flank.
Who owns the pipe your bathroom drains into
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.

FAQ
Frequently Asked Questions about Bathroom Renovation Epsom
Why do bathroom renovation quotes in Epsom vary so much?
Quotes for bathroom renovation in Epsom vary because they rarely price the same work, even inside £6,000 to £20,000 or more (London-derived). One builder includes making good and Part F extraction to outside, and Part P certification for any new circuit, another leaves both out. GS Renovation itemises every line for the KT17 property, so you can see what is in and what is missing. Compare scope before totals.
Do you need permission for a new soil pipe or extractor on an Epsom elevation?
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.
Does anyone inspect joists notched for a new bathroom in Epsom?
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.
Which parts of a bathroom refit in Epsom are notifiable, and who deals with them?
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 can a new bathroom go in a pre 1900 Epsom Town house?
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.
