A full bathroom renovation in the UK typically costs between £3,500 and £12,000, depending on the size of the room, the quality of fixtures, and whether you need structural work. Labour alone accounts for roughly 40-50% of the total bill.

Average Costs by Bathroom Type

A basic bathroom refit — replacing the suite, re-tiling, and updating plumbing — starts around £3,500 for a small room. A mid-range renovation with quality fixtures, underfloor heating, and a walk-in shower runs £6,000 to £8,000. For a premium finish with designer fixtures, wet room conversion, and bespoke storage, expect £10,000 to £15,000+.

What Affects the Price?

Several factors push costs up: moving plumbing (especially soil pipes), structural changes like removing walls, waterproofing for wet rooms, and underfloor heating. London and the South East are typically 20-30% more expensive than the rest of the UK.

How to Save Money

Keep existing plumbing layouts where possible — moving a toilet or shower tray adds £500-1,500. Buy your own fixtures (many fitters are happy with this) and compare at least three quotes. Some fitters offer package deals that bundle labour and materials.
