Bathroom Q&A

What people
ask us.

How much does a bathroom installation cost?

Bathroom installations usually start from £4,500 for a straightforward refresh. New layouts, wet rooms and premium finishes cost more.

Can I get a fixed bathroom quote online?

Yes. Answer the online questions and you get a fixed, itemised price before a site visit. A confirmation visit may still be needed before work starts.

How long does a bathroom take?

A like-for-like bathroom is typically 8-10 working days. New layouts, wet rooms and larger builds are usually 12-18 working days.

Do you cover Crawley, Horley and Reigate?

Yes. Bathroom installations are available across Surrey, Sussex and nearby towns including Crawley, Horley, Reigate, Redhill, Lingfield and Oxted.

What is included in the bathroom price?

The quote covers the agreed labour, main materials and installation scope. TriFlow is not VAT registered, and the quote breaks materials and labour line by line.
