If you’re planning to renovate your bathroom, one of the first questions you’ll ask is, “How much does a new bathroom cost?”
The cost of a bathroom renovation in London depends on the size of the room, the quality of the fixtures and fittings, and the amount of plumbing, tiling and electrical work required.
At Rocko Construction, we’ve completed bathroom renovations across London, from modern en-suites to luxury family bathrooms. This guide explains what you can expect to pay in 2026 and what factors influence the final price.
Bathroom Type Average Cost
Small Cloakroom £ 3,000.00 - £ 5,000.00
Standard bathroom £ 6,000.00 - £10,000.00
Premium bathroom £ 10,000.00 - £ 15,000.00
Luxury bathroom £ 15,000.00 - £ 30,000.00 +
Every project is different, but these figures provide a realistic guide for homeowners planning a renovation in London.
Several factors determine the final cost of your new bathroom.
Larger bathrooms require more materials, labour and installation time.
Moving the toilet, shower or bath usually increases costs because new pipework must be installed.
Large-format porcelain tiles and natural stone are generally more expensive than standard ceramic tiles.
Vanity units, storage cabinets and bespoke furniture can significantly influence the overall budget.
Premium taps, rainfall showers, freestanding baths and designer toilets all increase the final cost.
New lighting, extractor fans, electric mirrors and underfloor heating all require certified electrical installation.

Bathroom Suite £1,500.00 - £5,000.00
Wall & Floor Tiling £ 1,200.00 - £4,000.00
Plumbing £ 800.00 - £2,500.00
