Bathroom Renovation Pimlico

GS Renovation renovates bathrooms and en-suites across Pimlico, fitting modern, watertight rooms into the stucco townhouses and conversion flats of SW1. We handle tanking, drainage, ventilation, tiling and underfloor heating, and we make the most of the tight spaces that period layouts leave behind.

In Pimlico, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Pimlico: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Pimlico home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Waterproof bathrooms in Pimlico period homes

Fitting a bathroom into a Pimlico townhouse means working with timber floors, older drainage and walls that have moved over the best part of two centuries, 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.

Housing in Pimlico

Pimlico has about 10,180 homes on the Council Tax list: 55% pre-1919, 10% interwar and 34% post-war, with flats making up 94% and houses 6%. Since most homes here are flats, a bathroom in a flat in Pimlico sits over a neighbour's ceiling, so it is tanked before tiling and a moved WC needs the freeholder's licence.

Adding a bathroom in a Pimlico conversion under Westminster's rules

A second bathroom or an en-suite in a Pimlico flat means taking space from a bedroom or hallway, which changes the layout. Westminster's building notice route is only open where the layout is unaffected and the work is not affected by the Fire Safety Order, so a new bathroom in a converted Pimlico house goes in as full plans. Westminster charges it under the minor works heading for a bathroom or kitchen fit out in one property, identical on both routes, so the drawings rather than the fee decide the route. Those drawings must show the waste fall to the house's shared stack and the extract route to outside.

Programme the order of purchase around the decision. Westminster aims to decide full plans within 5 weeks and warns that some take longer, and in Pimlico, where 94% of homes are flats, the freeholder may want the approved drawings before issuing a licence. Long lead sanitaryware can be ordered while the application is live, but tiles and stone wait until the tray position and its falls are confirmed. In a stucco house the stack position is fixed and the joists run one way, so the approved layout is the one that works with both.

Space-saving en-suites for Pimlico townhouses

Pimlico's stucco 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 and heating, with the notifiable electrics certified by a registered electrician. The finished rooms feel generous for their size and are built to cope with daily use in a busy SW1 period home.
