Bathroom RenovationCost Calculator

A typical full bathroom renovation in the UK in 2026 costs £5,000–£8,500 for a medium-sized bathroom with standard fixtures. A small bathroom refurbishment starts around £3,500, while a large luxury renovation can reach £12,000–£20,000+. These prices include labour, materials, tiling, sanitaryware, and plumbing. London and the South East typically add 25–35% to these figures.

A full bathroom refurbishment typically includes: strip-out and disposal of old bathroom, new bath or shower enclosure, toilet, basin and vanity unit, full wall and floor tiling, new plumbing for all fixtures, bathroom electrics (extractor fan, lighting, shaver socket), and decoration. Underfloor heating, feature tiles, bespoke joinery and freestanding baths are extras that push costs toward the luxury end.

A typical full bathroom renovation takes 5–10 working days (1–2 weeks). A small en-suite can be done in 3–5 days. A large luxury bathroom with bespoke features may take 2–3 weeks. The largest time variables are tiling (drying and grouting takes 24–48 hours per stage) and plumbing/electrical inspections. Most bathroom fitters work alone or in pairs, so factor in prep and completion time.

Supplying fixtures yourself can save 15–25% on materials if you shop around — bathroom fitters typically add a 20–30% markup on sanitaryware. However, you bear the risk if items arrive damaged or are the wrong size. If fixtures are incorrect or faulty, the fitter will charge for return visits. For standard bathrooms, supplying your own sanitaryware is a common and cost-effective approach. For complex bespoke work, let the fitter supply everything.

No — internal bathroom renovations do not require planning permission in England, Scotland, Wales or Northern Ireland. However, Building Regulations approval may be required for new drainage connections, structural alterations, or certain electrical work in bathrooms (Part P regulations govern bathroom electrics). Your bathroom fitter should advise on any notifications required. Listed buildings require Listed Building Consent for any alterations.

Bathroom tiling costs £30–£75 per m² in the UK in 2026, including labour and standard tiles. Budget tiles cost £10–£20/m², mid-range £20–£50/m², and premium or large-format tiles £50–£150/m². Labour to lay tiles costs £20–£40/m² for standard wall tiles; intricate patterns, large-format tiles, or mosaic work costs more. Floor tiling with underfloor heating installation adds £50–£100/m² to the floor cost.
