How Much Does a Bathroom Renovation Cost in the UK?
Typical UK budgets for a bathroom refresh, a full refit and a premium renovation, what pushes the price up, and how to compare quotes fairly.
"How much will a new bathroom cost?" is one of the first questions people ask, and the honest answer is that it depends on the size of the room, the finish you choose and whether anything moves. This guide gives realistic UK ranges from industry guides, explains what drives the price and shows how to compare quotes properly.
The quick answer
- Budget refresh, replacing the suite with basic tiles: roughly £2,500 to £4,500
- Mid-range full refit: roughly £5,000 to £9,000
- Premium refit with a wet room or freestanding bath: £10,000 to £20,000 or more
- London prices are usually higher than the national average
- Keep a contingency of 10 to 15 percent for problems found during strip-out
These ranges come from UK industry cost guides published in 2026 and are a starting point only. Your quote depends on your room and choices.
What is included at each level
| Level | Typical scope |
| Refresh | New suite in the same positions, basic tiling or panels, new taps, sealing |
| Mid-range refit | Full strip-out, new suite, floor and wall tiling, shower and screen, extractor fan, decoration |
| Premium | Layout changes, wet room or walk-in shower, freestanding bath, large-format tiles, underfloor heating, bespoke storage |
What pushes the price up
- Moving the toilet, shower or bath, which means new waste and supply runs
- Rotten floorboards, damp walls or old pipework found during strip-out
- Large-format or intricate tiling, which takes much longer to lay
- Wet rooms, which need careful tanking and floor falls
- Concealed cisterns, wall-hung toilets and concealed shower valves
- Electrical work, which must be done by a qualified electrician
- Difficult access, parking and waste removal
Ways to keep costs down
- Keep fittings in their existing positions
- Choose standard-size tiles and tile only the wet areas
- Use wall panels instead of tiles in showers
- Buy the suite yourself, but agree delivery checks with your fitter first
- Repair rather than replace items that are in good condition
- Plan everything before work starts, as changes mid-job cost more
How to compare bathroom quotes
- Check what is included: strip-out, disposal, plumbing, electrics, tiling, flooring, decoration
- Check who supplies the suite, tiles and fittings
- Ask how hidden problems will be priced if found
- Ask how long the bathroom will be out of use
- Compare like with like, not just the total

Frequently asked questions
How long does a bathroom refit take?
A standard refit often takes one to two weeks. Layout changes, specialist trades and waiting for tiles to cure can extend that.
Do I need building regulations approval for a new bathroom?
Like-for-like replacements usually do not, but new drainage, ventilation or electrical circuits may. Electrical work in a bathroom must meet Part P.
Is it cheaper to supply my own suite?
Sometimes, but agree who checks the delivery and what happens if parts are missing or damaged.
