Typical cost in 2025
Most homeowners pay around £5,500 for a full bathroom strip-out and re-fit, mid-range suite
What affects the price?
Bathroom size
A standard bathroom (around 4–6m²) costs less than a large family bathroom or en-suite. Larger rooms mean more tiling, more materials, and more labour time.
Suite quality
Budget suites start around £200–£500. Mid-range suites run £500–£1,500. Designer suites can exceed £3,000 before installation. Your suite choice has the biggest impact on overall cost.
Tiling
Tiling is labour-intensive. Expect £30–£50/m² for labour plus materials. Floor-to-ceiling tiling in a full bathroom typically adds £1,500–£3,000 over a part-tiled option.
Underfloor heating
Electric underfloor heating mats can be added for £300–£700 installed. Wet system underfloor heating costs more but is more efficient for larger bathrooms.
Plumbing changes
Keeping existing pipework positions is cheapest. Moving the toilet, bath, or shower to a new location requires significant re-routing and adds £500–£1,500 to the job.
Typical cost breakdown
Estimates are based on UK average rates in 2025. Prices in London and the South East are typically 20–30% higher.
Frequently asked questions
How long does a bathroom installation take?
A full strip-out and re-fit typically takes 5–8 days for a single tradesperson or team. Complex jobs with extensive tiling or plumbing rerouting can take up to 2 weeks.
Do I need planning permission for a new bathroom?
Generally no — like-for-like replacements and refits don't require planning permission. If you're converting a bedroom into a bathroom or making structural changes, check with your local council.
Should I use one contractor or separate tradespeople?
A single bathroom installer who handles plumbing, tiling, and electrics is more convenient and often cheaper. Coordinating separate trades takes more time and increases the risk of delays.
What's the difference between a wet room and a walk-in shower?
A wet room is a fully waterproofed space where water drains from the whole floor. A walk-in shower has a defined tray or area. Wet rooms cost more due to tanking but are easier to clean and more accessible.
Does a new bathroom add value to my home?
Yes — a quality bathroom renovation can add 3–5% to your home's value. A dated or damaged bathroom is one of the top reasons buyers reduce their offers.
