The Calacatta marble specification, book-matched, is absolutely stunning. Lefroy Brooks brassware, underfloor heating, freestanding bath — every detail delivered exactly as designed. It feels like the finest hotel suite we’ve stayed in.

We were sceptical anyone could deliver a walk-in rain shower of the standard we’d seen in hotels abroad. The digital mixer, Porcelanosa tiling, and perfect tanking have given us exactly that — and the site was spotless throughout.

Three bathrooms refurbished in a single project, all in 5 weeks. The underfloor heating is fantastic, the fitted vanities are beautifully made, and the design consultation genuinely helped us make better decisions than we would have alone.

Built for Chelsea Bathrooms

Chelsea bathrooms range from compact cloakrooms in Victorian terraces to statement hotel-style master suites in Georgian townhouses and mansion flats. Every project demands precision waterproofing and premium finish.

Waterproofing & Tanking

Chelsea’s period properties often have timber floors, solid plaster walls, and complex service routes. We apply liquid waterproof membranes to all wet-zone walls and floors, test before tiling, and provide a 10-year waterproofing guarantee to protect the structure below.

Natural Stone & Premium Specification

We work regularly with Calacatta, Carrara, Statuario and Arabescato marble, plus Porcelanosa, Marazzi, and Solus Ceramics porcelain. Sanitaryware and brassware from Lefroy Brooks, Samuel Heath, Fantini, Dornbracht, and Hansgrohe.

Underfloor Heating & Comfort

Almost every Chelsea bathroom we deliver includes underfloor heating — either electric or wet systems. Smart thermostats, towel-rail integration, and correctly specified insulation buildups deliver luxurious comfort with low running costs.

Bathroom Refurbishment Questions

Common questions about bathroom refurbishment in Chelsea.

How much does a bathroom refurbishment cost in Chelsea?
Chelsea bathroom refurbishment typically starts from £12,000 for a cloakroom and reaches £65,000+ for a full master bathroom with natural stone and premium brassware. Most Chelsea bathrooms fall between £22k and £45k. We provide a detailed fixed-price quotation after a free design consultation.
How long does a bathroom refurbishment take in Chelsea?
A typical Chelsea bathroom refurbishment takes 3 to 5 weeks on site. Master bathrooms with extensive natural stone or complex plumbing may take 6 weeks. Material lead times — particularly for book-matched marble — run in parallel. We provide a detailed programme before works commence.
What is tanking and do I need it?
Tanking is the application of a liquid waterproof membrane to walls and floors before tiling. It prevents water ingress into the fabric of the building. In Chelsea’s period properties, full tanking is essential. We apply, test, and guarantee tanking for 10 years.
Can you install a freestanding bath?
Yes. We regularly install freestanding baths from Victoria + Albert, Waters, Drummonds, and William Holland. We verify floor load-bearing capacity, reinforce structure where needed, and manage concealed supply and waste routing.
Do you work with natural stone?
Yes — we are Chelsea’s natural stone bathroom specialists. Calacatta, Carrara, Statuario, Arabescato, Emperador, and travertine. We template every slab, mitre-wrap corners where specified, and coordinate delivery with cutting and installation.
Can I refurbish one bathroom while living in the house?
Yes, usually, provided you have another usable bathroom. We install full dust protection, restrict works hours where requested, and coordinate water shut-offs with short notice.
Do you install underfloor heating?
Yes. We install both electric mat systems (suitable for retrofits) and wet pipe systems (where there is build-up height available). All with smart thermostats and full heat-loss calculations.
What warranties do you provide?
We provide a 10-year insurance-backed waterproofing guarantee, a 5-year workmanship guarantee, manufacturer warranties on all brassware and sanitaryware, and Part P & Part G certification where applicable.
