Bathroom Plumbing in the UK: Frequently Asked Questions
How long does a full bathroom refit take?
Plumbing work for a standard bathroom refit takes 2-4 days. The full project including tiling, electrics, and decoration typically takes 1-2 weeks. An en-suite or small shower room may be quicker at 1-2 days for plumbing.
Can I move my toilet to a different wall?
Yes, but it adds cost (£300-£800 extra) as the soil pipe and drainage need rerouting. Moving a toilet more than 1-2 metres from the existing soil stack may require a macerator pump or additional drainage work.
