Bathroom Renovation Cost Calculator UK

The average UK bathroom renovation in 2026 costs between £5,500 and £8,500 for a mid-range, like-for-like refit of a standard family bathroom. Smaller cloakrooms typically come in under £3,000, while luxury bathrooms with premium tiling, underfloor heating and bespoke vanities can push beyond £15,000.

Labour usually accounts for 40–55% of the total, with materials making up the remainder. A typical mid-range project takes 7–12 working days from strip-out to final silicone, assuming no major plumbing or structural changes.

London prices generally sit 20–30% above the national average. Outside the South East, you can expect more competitive labour day rates, particularly in the North of England, Scotland and Wales.

A standard UK refit usually covers full strip-out and disposal, first and second-fix plumbing, electrics for lighting and shaver sockets, plastering, full wall and floor tiling, and the supply and fit of a new suite (toilet, basin, bath and/or shower).

Optional extras that significantly affect price include underfloor heating (£500–£1,200), heated towel rails (£150–£400), bespoke vanity units (£600–£2,500), large-format porcelain tiles, and any structural changes such as moving a soil stack or repositioning the toilet.

Always confirm whether VAT, waste removal, and making good of adjacent rooms are included in your quote — these line items are commonly overlooked and can add £400–£900 to the final bill.

A full wet room conversion involves tanking the entire room (waterproof membrane), installing a graded floor with a linear drain, and tiling throughout. Expect £6,000–£12,000 for a properly executed wet room in the UK, with the tanking and drainage adding around £1,500 over a standard refit.

Wet rooms add value to family homes with multiple bathrooms but can hurt resale on properties with only one bathroom — most UK buyers still prefer at least one bath. A walk-in shower with a low-profile tray is often a more cost-effective compromise.

Keeping the existing layout is the single biggest saving — moving plumbing fixtures can add £600–£1,500 to a project. Choose mid-range, in-stock suites from UK merchants (Victoria Plum, Wickes, Soak.com) rather than special-order ranges with long lead times.

Get three written, itemised quotes and check that each tradesperson is Gas Safe registered (if a boiler or gas appliance is involved) and a member of a competent person scheme such as NICEIC for electrics. Avoid paying more than 25–30% upfront.
