Where the money goes

Labour is usually the largest single cost. A full refit can involve a plumber, a tiler, an electrician and a plasterer, either coordinated by one bathroom fitter or arranged separately by you.

  • Stripping out the old bathroom and removing waste
  • First fix plumbing and any pipework changes
  • Electrical work: lighting, extractor fan, electric shower or underfloor heating
  • Plastering, boarding and waterproofing
  • Tiling walls and floor
  • Second fix: fitting the suite, taps, shower and accessories
  • The suite, tiles, brassware and materials themselves

What makes bathrooms more expensive

Moving the toilet, adding a walk-in shower or wet room, fitting wall-hung sanitaryware or concealed valves, replacing old pipework and dealing with rotten floors all add cost. So do premium tiles, which take longer to lay, and designer brassware. Upgrading the hot water system to supply a better shower can also be part of the project.

Getting comparable quotes

Ask each installer to break their quote down: labour by trade, materials they're supplying, waste removal and what happens if they find problems. Agree who supplies the suite and tiles. A clear specification – even a simple sketch and a list – makes quotes far easier to compare. Most full refits take one to three weeks, depending on the scope.

Common questions

How long does a bathroom refit take?

Often one to two weeks for a straightforward refit, longer if the layout changes or there are delays with materials.

Is it cheaper to buy the suite myself?

It can be, but check compatibility with your plumbing and agree with the installer what they'll guarantee.

Do I need building regulations approval for a new bathroom?

A like-for-like refit usually doesn't, but new drainage, some electrical work and adding a bathroom where there wasn't one may need to meet Building Regulations. Your installer should advise.
