Cost of Fitting a Bathroom in the UK (2025)
Fitting a bathroom costs £1,500–£4,000 for labour. A full supply and fit costs £4,000–£12,000 depending on the standard of fixtures chosen.
What does bathroom fitting involve?
A bathroom fit includes stripping the old bathroom, first fix plumbing (moving or extending pipes to new positions), boarding and waterproofing wet areas, tiling walls and floor, fitting sanitaryware (bath/shower, basin, toilet, towel rail), second fix plumbing (connecting to the supply and waste), and electrics (extractor fan, lighting, shaver socket). Most bathroom fitters either carry out all trades themselves or work with trusted subcontractors.

How long does fitting a bathroom take?
A standard bathroom fit takes 5–10 working days from strip-out to completion. En suites typically take 4–7 days. Wet rooms take longer due to additional waterproofing work.
Can I save money by buying my own bathroom?
Possibly — but buying online without seeing the quality in person carries risk. Bathroom fitters with trade accounts can often match or beat retail prices on quality brands. Get a quote both ways before deciding.
Should my bathroom fitter be qualified?
For work involving gas, your tradesperson must be Gas Safe registered. Electrical work in bathrooms must comply with Part P. Plumbing does not require a licence, but using an experienced bathroom fitter with verifiable reviews is important.
What should I ask a bathroom fitter before hiring?
Ask for examples of recent similar work, check reviews, confirm their trade qualifications, ask whether all trades are included in the quote, and get a clear payment schedule tied to milestones.
