How much does a new bathroom cost in the UK?

Checkatrade's New Bathroom Cost guide (updated March 2026) puts £4,000 as the entry point for a basic refresh, £5,500-£8,000 (average £7,000) for a standard mid-range refit, and £14,000+ for a larger or high-end project. Size, spec, and whether you change the layout are the main drivers.

What adds the most to a bathroom renovation?

Moving the layout (relocating the toilet or soil stack) and the extent of tiling are the biggest swings, often more than the suite itself. A wet-room conversion adds £1,000-£5,000 for tanking and forming the fall to the drain, and underfloor heating adds a few hundred pounds.

How much of the cost is labour versus materials?

Labour typically runs 35-55% of the total across current UK bathroom cost guides (Checkatrade, MyBuilder, 2026), a higher share than most rooms because tiling and plumbing are labour-intensive. Stripping out the old suite alone is often £600-£1,000 before any new work begins.

How long does a bathroom renovation take?

A budget refit is typically 6 to 12 days, a standard mid-range job 7 to 15 days, and a premium or layout-changing job 9 to 16 days. Wet-room conversions take longer because the tanking needs to cure before tiling.

Does location change the price?

Yes. No single published UK study prices a bathroom-specific regional premium, but tradespeople's day rates run noticeably higher in London and the South East than in the North, Wales or the Midlands. This calculator applies a +28% working adjustment for London/South East as Tradehand's own estimate, not a cited statistic; the materials cost the same everywhere, the difference is purely labour rates.

How to use the Bathroom Renovation Cost Calculator

1Choose the bathroom size; a small en-suite costs less than a large family bathroom for the same spec.
2Pick the spec level: budget (white suite, basic tiles), mid-range (better suite, porcelain tiles), or premium (freestanding bath, walk-in shower, custom).
3Toggle the big cost-drivers: a wet-room conversion, moving the toilet or plumbing, and underfloor heating each add meaningfully.
4Set your region, then read the from / typical / up-to range. Use it to sense-check quotes and always get two or three fixed quotes before committing.

How the Bathroom Renovation Cost Calculator works

A bathroom refit isn't a formula; it's the suite and materials plus labour, with layout changes and tiling the biggest swing factors. Start from the spec band and adjust for size and the extras.

Estimate = (spec band × size factor + extras) × regional factor

Mid-range spec: roughly £5,500-£8,500 for a standard bathroom.
Add a wet-room conversion (£3,000) and moving the toilet (£2,000): £10,500-£13,500.
In London/SE (×1.28): about £13,400-£17,300.
Labour typically makes up 35-55% of the total across current UK bathroom cost guides (Checkatrade, MyBuilder, 2026), higher than most rooms because of the tiling.

These bands are Tradehand's own working estimate, built around Checkatrade's New Bathroom Cost guide (updated March 2026): £4,000 for a basic refresh, £5,500-£8,000 average £7,000 for mid-range, £14,000+ for a larger or high-end project. Not a quote. The suite quality, tiling area, and any layout change move the price the most, so get fixed quotes from tradespeople who've seen the room.
