Luxury bathroom and wet-room refurbishment in Pimlico. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms and en-suites across Pimlico, fitting modern, watertight rooms into the Georgian and Regency townhouses of SW1. With over 30 years in Westminster's period and listed homes, we handle tanking, drainage, ventilation, tiling and underfloor heating, and we make the most of the tight spaces that period layouts leave behind.

Fitting a bathroom into a Pimlico townhouse means working with timber floors, older drainage and walls that have shifted over two hundred years, so proper waterproofing is essential. We tank wet rooms and walk-in showers fully before tiling, so water is contained rather than finding its way into period floors and the rooms below. Getting the tanking, falls and drainage right first time is what keeps these bathrooms sound for the long term.
Ventilation matters just as much in the enclosed internal bathrooms common in tall SW1 terraces, where there is often no external window. We install extraction that clears moisture properly and protects the fabric of the house. Underfloor heating, quality tiling and considered lighting finish the room, and where a home is listed or in a conservation area we keep pipework routes discreet to avoid disturbing protected joinery and floors.
Regency terraces were not built with modern bathrooms in mind, so adding an en-suite or fitting a family bathroom into an awkward box room takes careful planning. We design layouts that use every inch, from walk-in showers that suit narrow footprints to wall-hung basins and concealed cisterns that free up floor space. Careful setting-out of the drainage and soil pipe is what makes a compact SW1 en-suite work rather than feel cramped.
Across a multi-storey Pimlico townhouse we coordinate several new bathrooms at once, tying them into the existing plumbing and waste while upgrading tired services behind the walls. We handle the tiling, sanitaryware, heating and the notifiable electrics under building regulations, all in-house. The finished rooms feel generous for their size and are built to cope with daily use in a busy period home near the West End and the River Thames.
Bathrooms in Pimlico's period townhouses demand thorough tanking, sound drainage and clever layouts in tight, often windowless spaces. GS Renovation delivers all of it under one team, from waterproofing and ventilation to tiling, underfloor heating and notifiable electrics. With 30+ years in SW1's Georgian and listed homes, we build watertight, space-efficient bathrooms that protect the fabric of the house.

FAQ
No. Bathroom renovation is priced from scope, so a Pimlico home is not quoted higher than the same house over in Marylebone. Where costs do rise is in period stock and awkward access, both of which are checked at the SW1 property. GS Renovation shows those as separate lines so you can see the reason. The SW1 survey costs nothing and there is no obligation afterwards, in Pimlico or anywhere in Westminster. 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.
Modern stock is usually faster to finish. Where bathroom renovation is concerned the difference shows after the structural stage, because a Georgian and early Victorian Pimlico property needs far more reinstatement around the SW1 works. GS Renovation allows for that difference in the programme it issues. Both types are surveyed the same way in Westminster before any dates are committed. Ask GS Renovation on 07472 424 226 what a Georgian and early Victorian property at SW1 is likely to require in practice.
The work area is separated from the rest of the house before anything starts. On a bathroom renovation job at an SW1 address GS Renovation seals openings, protects floors and stairs, and clears debris daily rather than at the end of the Pimlico project. Materials are stored tidily and the street is kept clear. Neighbours in a Westminster terrace notice the difference immediately. Ring 07472 424 226 to discuss access. Neighbours in Westminster terraces notice the SW1 difference immediately.
Part F sets the requirement, and in practice that means mechanical extraction to outside, never into a loft void. Condensation is a persistent problem in Pimlico's older solid-wall properties, so we size extraction properly at the SW1 address rather than fitting the smallest unit that complies.
Usually earlier alterations that were never done properly. Bathroom renovation at an SW1 property of that age regularly uncovers removed structure, notched joists or wiring that predates any certificate, and each is costed and agreed before we continue. GS Renovation names the likely candidates at the Pimlico survey. Westminster City Council is notified where a change affects approved work. Ask on 07472 424 226 what bathroom renovation commonly uncovers at an SW1 address of that sort of age.
Yes. Pimlico's Regency townhouses rarely have space to spare, so we design en-suites around the footprint using walk-in showers, wall-hung basins and concealed cisterns, and set out the drainage carefully to make a small room work. We fully tank and ventilate the space, then handle tiling, heating and the notifiable electrics under building regulations. Internal bathroom work does not need planning permission.
The whole borough, and beyond it. Bathroom renovation takes GS Renovation across Pimlico, Marylebone and much of Central London in a normal month, and there is no surcharge for an SW1 address in one part of Westminster over another. Building control goes through Westminster City Council either way. Ring 07472 424 226 to confirm your street. The survey that follows is free and carries no obligation.
