Bathroom Cost Calculator

Tick what applies to your project for an indicative price band. This is a ballpark based on the same cost factors covered in our full cost guide — not a quote. A £125 survey measures your actual room and produces a written, fixed figure.

What does your project involve?

Moving the WC, shower or basin to a new position Full wet room floor (not a tray enclosure) Natural stone rather than porcelain tiling Underfloor heating Shower toilet or digital shower Moving or removing a stud wall Bespoke-cut glass (angled wall, non-standard opening) More than 3 sanitaryware items in one room

Indicative range

From £3,500

A straightforward fit-only installation: existing layout kept, no waste positions moved, mid-market sanitaryware and porcelain tiling to a standard wet area.

How this estimate works

Each factor ticked above reflects a real driver of installation cost — moved waste positions, full wet room tanking, natural stone fitting time, and similar — set out in detail in our bathroom installation cost guide. The bands shown match those used on our pricing page. This tool has no connection to any quote — it's a starting point for budgeting, not a substitute for the £125 survey.
