Prices include 20% VAT. New builds and some energy-saving works can qualify for 0% or reduced VAT; ask your installer.
On top of whatever you agree with a builder, set aside a contingency of 15 to 20% for the unforeseen: this work opens up the existing fabric, where damp, rotten timber or outdated wiring only show once things are apart. How much contingency you need explains the guidance.
What drives the price
- Moving fixtures: keeping the toilet and basin where they are saves 30 to 40 percent.
- Tiling: floor-to-ceiling roughly doubles the tiling bill versus half height.
- The suite itself: standard white ware is cheap; freestanding tubs and walk-ins are not.
- Hidden work: old pipework and walls only reveal themselves after strip-out.
All figures come from the same validated 2026 price data as the calculator above, built on the sources listed higher up on this page, each opened and checked on 26 August 2026 (see how we price), so this page and your estimate can never disagree.

Frequently asked questions
What does moving the toilet or basin add?
Rerouting waste pipes means opening and restoring the floor, which is why keeping the layout saves 30 to 40 percent. Our free bathroom planner shows the plumbing consequences of every move before you commit.
What should I do first?
Three steps, in this order. First, turn the guide range above into your own number: the calculator on this page adjusts for size, finish level and region in under a minute, free and without email. Second, if the layout matters, bathrooms and kitchens especially, draw the room to scale in the free planner; moving plumbing is usually the biggest hidden cost, and you want to know that before anyone quotes. Third, get at least three itemised quotes and compare them line by line against your range before you commit; the quote check on this site gives you an honest verdict per quote.
Do these prices include VAT?
Yes, all ranges include 20% VAT. New builds and some energy-saving works can qualify for 0% or reduced VAT; ask your installer whether your project applies.
Why is London so much more expensive?
Labour is the driver: London trades charge roughly 25% above the national average, and parking, access and waste logistics add friction. Nationally this project runs £5,500 to £8,500; the calculator switches region in one click.
How accurate is this range?
It is a guide range from national 2026 cost guides, adjusted for finish level and region. Real quotes vary per trade, property and specification; treat it as a starting point, budget 10 to 15 percent contingency, and always get at least three itemised quotes.
