Planning a new bathroom and want a straight answer on price? The Cost of Renovation of Bathroom. Usually falls between £4,500 and £15,000 in 2026, depending on size and finish. That range feels huge until you understand what drives it.
This guide breaks the numbers down by room size, fittings, and labour. You will also get real ways to save money without cutting corners on safety.
How Much Does a Bathroom Renovation Cost in 2026
How Much Does a Bathroom Renovation Cost in 2026? Most homeowners spend between £4,500 and £9,000 for a standard family bathroom. A small cloakroom refresh can come in under £3,000. A luxury full bathroom with a wet room or bespoke cabinetry can reach £15,000 or more.
These figures cover labour, materials, plumbing, and tiling. They do not usually cover structural work like moving walls. If your project includes that, budget extra on top.
Average Bathroom Renovation Cost By Size
Size is the single biggest factor in your final bill. Here is a realistic breakdown for 2026:
- Small bathroom or cloakroom (under 4m²): £2,500 to £5,000
- Standard family bathroom (4 to 6m²): £5,000 to £9,000
- Larger bathroom (6 to 9m²): £8,000 to £13,000
- Wet room conversion or luxury suite: £12,000 to £20,000+
A small room does not always mean a small bill. Tight spaces take longer to tile and plumb, which can push installation cost up per square metre even when the room itself is compact.
Bathroom Remodel Cost Breakdown
Knowing the total figure helps with budgeting, but the real value comes from seeing where each pound goes. Here is a typical Bathroom Remodel Cost Breakdown for a mid-range family bathroom.
Labour Costs
Labour usually makes up 40 to 55 percent of your total spend. This is higher than most home improvement projects because a bathroom pulls in several trades at once.
- Plumber: £200 to £350 per day
- Tiler: £150 to £350 per day
- Electrician: £200 to £350 per day
- Bathroom fitter (coordinating the job): £250 to £400 per day
Most standard jobs take 7 to 14 working days on site, including strip-out, first-fix plumbing, tiling, and snagging.
Material and Fixture Costs
This is where personal taste has the biggest impact on renovation cost.
- Bathroom suite (toilet, basin, bath or shower): £600 to £3,500
- Tiles: £25 to £100 per square metre, before fitting
- Shower heads and shower systems: £80 to £600
- Vanity unit and storage: £150 to £900
- Extractor fan: £150 to £400 fitted, essential for damp control.
Hidden Costs People Forget
Quotes can look tidy on paper and still miss real expenses. Watch for these:
- Removing the old suite: £600 to £1,000
- Skip hire: around £300 per week
- Repairing damp or rotten subfloor in older homes
- Building control sign-off if you move pipework or wiring
Being upfront about these with your contractor avoids nasty surprises halfway through the job.
Bathroom Renovation Budget / Cost Factors
Several things push your bathroom renovation prices up or down. Knowing these in advance helps you set a realistic Bathroom Renovation Budget / Cost Factors plan before you get quotes.
Layout Changes
Keeping your toilet, bath, and basin in their current spots is the cheapest option. Moving the toilet means rerouting the 110mm waste pipe, which can add £1,500 to £3,000 on its own.
Underfloor Heating
Underfloor heating is one of the most requested upgrades for 2026 projects. Electric mat systems cost £80 to £120 per square metre fitted. It is a comfortable add-on, but it does increase costs if you are working to a tight budget.
Tile Choice
Large-format tiles and natural stone look striking but take longer to cut and lay. Herringbone patterns can add 25 to 50 percent to tiling labour alone.
Wet Rooms
A wet room needs floor-to-ceiling waterproofing, called tanking, plus a sloped floor and a proper drain. This level of work adds £2,000 to £4,000 over a standard shower room.
Building Age
Older properties often hide problems behind the walls. Damaged pipework, rotten joists, or weak flooring can all add unplanned cost once the old suite comes out.
How to Save Money on Your Bathroom Renovation
You can save money without making the bathroom feel cheap. Try these approaches:
- Keep your existing layout instead of moving pipework
- Choose mid-range fittings instead of premium brands for items like taps and shower heads
- Reuse a vanity unit if it is still in good condition
- Get three written quotes before choosing a contractor
- Buy tiles and sanitaryware in sale periods rather than rushing the order
- Limit full-height tiling to wet zones only, using paint elsewhere
A clear plan before work starts is the single best way to control your average cost. Once a contractor is on site, changes get far more expensive.
DIY Versus Hiring a Professional
DIY can lower upfront spend, but bathrooms leave little room for error. Poor waterproofing or incorrect plumbing often costs more to fix later than it would have cost to do properly the first time.
Hiring qualified trades protects you in three ways:
- Correct certification for plumbing and electrical work under UK building regs
- Warranty cover if something fails after the job is done
- Faster turnaround, since experienced fitters know how to sequence the work
For most homeowners, a mix of DIY prep (clearing the room, choosing fittings in advance) paired with professional fitting gives the best balance of cost and quality.
Does a Bathroom Renovation Add Value to Your Home
A tired or outdated bathroom can put buyers off, especially in a competitive market. A well-planned full renovation often returns a good share of its cost at resale, particularly if the existing bathroom was the only one in the house or clearly needed work.
Buyers are also paying more attention to ventilation and damp control. A working extractor fan and good waterproofing matter just as much as how the room looks in photos.
What to Expect to Pay at Each Budget Level
If you only remember three numbers from this guide, make them these:
- Budget tier: £2,500 to £5,000 for a like-for-like suite swap, basic tiling, and standard fittings
- Mid-range tier: £5,000 to £9,000 for a full retile, quality fixture and fitting choices, and a new layout-friendly suite
- Premium tier: £10,000 to £20,000+ for a wet room, underfloor heating, bespoke storage, and high-end tiling
You should always expect to pay more in London and the South East, and budget an extra 10 to 15 percent as a contingency for older properties.
