How Much Does a Bathroom Renovation Cost in the UK? (2026 Prices)

A standard UK bathroom renovation costs between £4,500 and £9,000 in 2026 for a typical 4–8m² family bathroom, with most homeowners spending around £6,000–£7,500. A small ensuite or cloakroom refresh can cost as little as £2,000–£4,500, while a luxury bathroom or wet room with premium fittings and underfloor heating can run to £10,000–£20,000+. Labour typically makes up 45–55% of the total, with London and the South East adding roughly 20–30% on top of national averages.

The Short Version: Bathroom Renovation Costs at a Glance

These figures cover labour and materials for a typical UK home and assume no major structural or plumbing surprises once work begins.

What Drives the Cost of a Bathroom Renovation

1. 1. Room Size: Cost is often quoted per square metre, and in 2026 that typically works out to £1,500–£3,000 per m² for a full refit including labour. A small 3–4m² ensuite will naturally cost less in total than an 8–10m² family bathroom, even at the same specification level.
2. 2. Whether the Layout Changes: Keeping your toilet, bath, and basin in their existing positions is the single biggest cost-saving decision you can make. Moving the soil stack or rerouting pipework for a new layout typically adds £500–£2,000, and can extend the job by several days. If you can work around the existing plumbing positions, you'll usually save £500–£1,500 compared with a full layout change.
3. 3. Fixtures and Fittings: Labour costs are broadly similar regardless of which sanitaryware you choose — it's the suite, tiles, and brassware where prices vary enormously. A new bathroom suite (toilet, basin, bath or shower) typically costs £600–£2,500 per fixture depending on brand and quality, while tiles range from roughly £15–£150 per m² before fitting.
4. 4. Wet Rooms and Tanking: Wet rooms cost around 20–30% more than a comparable conventional bathroom because they require full floor-to-ceiling tanking (waterproofing), a specialist gradient screed for drainage, and non-slip tiles. Expect a tanking and gradient premium of roughly £1,500–£3,000 on top of standard renovation costs.
5. 5. Region: London and the South East typically add 20–30% to national average prices, largely reflecting higher trade day rates in those areas. Costs in the North of England and other regions tend to sit closer to, or below, the national average.
6. 6. Underfloor Heating and Extras: Underfloor heating adds roughly £1,500–£10,000 depending on the system and room size, and is one of the more popular upgrades in mid-range and luxury renovations.

Typical Cost Breakdown for a 6–8m² Family Bathroom

For a typical UK family bathroom, these line items combine to a total renovation cost of roughly £3,250–£12,400, depending on spec level and whether underfloor heating is included.

Worked Examples by Bathroom Type

• Small ensuite (3–4m², shower only): With a mid-range suite, standard tiling, and no layout change, expect to pay around £3,000–£7,000. Keeping the existing plumbing positions is especially valuable here, since these spaces have less room to absorb extra pipework costs.
• Standard family bathroom (6–8m²), same layout: A new suite in the same positions, full re-tiling, and new flooring typically costs £4,500–£8,000 and takes around 5–10 working days — the most cost-effective way to refresh a family bathroom.
• Full refurbishment with layout change: Moving the toilet, bath, or shower position pushes costs to roughly £5,500–£10,000, with the extra £500–£2,000 covering new pipework and potential drainage changes. This typically takes 7–12 working days.
• Wet room (any size): Expect £8,000–£15,000+, reflecting the tanking, gradient screed, and linear drainage that a wet room requires on top of standard renovation costs.
• Luxury or high-spec bathroom: Bespoke fitted furniture, a freestanding bath, large-format tiles, underfloor heating, and smart controls typically bring the total to £10,000–£20,000+, with some premium master ensuites exceeding this depending on scope.

How Long Does a Bathroom Renovation Take?

• Small suite refresh: 3–5 working days
• Standard family bathroom (same layout): 5–10 working days
• Full refurbishment with layout change: 7–12 working days
• Luxury or wet room renovation: 10–16 working days

Does a Bathroom Renovation Add Value to Your Home?

A well-executed bathroom renovation typically adds around 4–6% to a property's value. On the average UK home (roughly £290,000), that works out to an increase of approximately £11,600–£17,400.

That said, over-specifying relative to the rest of the property is a common mistake — a very high-end bathroom in a modest home rarely returns its full cost. Quality fittings, good tiling, and clean, timeless design tend to add the most value, while heavily trend-led choices (bold coloured suites, very specific patterned tiles) can date quickly and hold back resale appeal.

How to Keep Your Bathroom Renovation Costs Down

• Keep the existing layout: Reusing your current toilet, bath, and basin positions can reduce plumbing costs by up to 35%.
• Supply your own sanitaryware: Buying your suite, tiles, and accessories from trade suppliers yourself can widen your choice without inflating the bill.
• Avoid moving the soil stack: This is consistently one of the most expensive single changes in a bathroom renovation.
• Limit full-height tiling: Tiling floor to ceiling looks striking but adds significantly to both material and labour costs compared with tiling to a lower height.
• Get multiple quotes: Labour rates and markups vary between bathroom specialist firms, independent fitters, and multi-trade setups, so comparing at least two or three quotes is worthwhile before committing.
