What affects the price?
- Quality of sanitaryware — budget brands (B&Q own-label) cost £500–£800 for a complete suite; mid-range (Ideal Standard, Roca) cost £1,000–£2,500; premium (Duravit, Villeroy & Boch) cost £3,000–£8,000+
- Extent of tiling — floor and splash tiles only is cheapest; full floor-to-ceiling wall tiling adds significant materials and labour cost
- Shower type — over-bath shower rail with curtain is cheapest; wet room or frameless enclosure is most expensive
- Plumbing changes required — a like-for-like replacement with no pipework changes is cheapest; moving toilet or basin positions requires significant additional plumbing work
- Underfloor heating — electric or wet underfloor heating adds £300–£1,500 to installation cost but transforms the room
- Extractor fan — a standard extractor costs £50–£150; a heat recovery ventilation (HRV) system costs £300–£600
- Access for waste runs — if the property is a flat or upper-floor bathroom, routing new waste pipes may be complex and costly
- London and South East premium — typically 20–30% higher than national average
What's included in the price?
- Strip-out and disposal of existing bathroom suite
- Any required pipework modifications and new supply/waste connections
- Installation of bath or shower tray, toilet, basin, and any additional items
- Shower installation (over-bath or separate cubicle as agreed)
- Taps, valves, and waste fittings
- Waterproofing (tanking) to shower area as required
- Tiling (if included in quote) — floor, walls to agreed height
- Extractor fan
- Towel rail or heated towel rail (if included)
- Snagging and clean-up
How long does it take?
A standard bathroom refurbishment takes 5–8 working days for a complete strip-out and refit. This typically breaks down as: 1 day strip-out and prep; 1–2 days first-fix plumbing; 1–2 days boarding/waterproofing; 1–2 days tiling; 1 day second-fix plumbing and finishing. You will be without the bathroom throughout — plan for alternative arrangements or allow for evening re-commissioning of toilet facilities where possible. More complex projects (major layout changes, en-suite creation) take longer.
Do I need one?
A bathroom refurbishment is not a legal requirement, but most bathrooms have a practical lifespan of 15–25 years before plumbing components, tiles, and fixtures show significant wear. Key triggers for bathroom replacement: leaks or damp damage from an aging bath or shower seal; cracked or irreparable tiles; outdated or inefficient fixtures; poor shower pressure from old valves; or simply wanting to modernise the space. All plumbing work must comply with Water Supply (Water Fittings) Regulations 1999. Structural bathroom work in an upstairs room may need Building Regulations approval for the floor structure.
How do you avoid overpaying?
- Get at least 3 detailed written quotes — prices vary substantially between plumbers for the same specification
- Consider sourcing your own sanitaryware from trade bathroom centres (Victorian Plumbing, Bathstore, Plumbworld) and asking the plumber to supply labour-only — you can often save 20–30% on materials vs using the plumber's supply, but check the plumber will warranty their workmanship on customer-supplied goods
- Keep the toilet in its existing location — moving a toilet requires rerouting the soil pipe and adds significant cost
- Choose floor tiles over designer feature tiles — a mid-range porcelain tile installed by a good tiler looks as good as designer options at a fraction of the cost
- Time the refurbishment in late spring or summer when bathroom fitters and tilers are less in demand
- Ask about a straight switch-out vs full remodel — sometimes replacing fixtures in the existing positions with updated models is sufficient and much cheaper

Frequently asked questions
We’re happy to answer all your questions.
How much does it cost to refurbish a bathroom in the UK?
A full bathroom refurbishment costs £3,500–£8,000 for a mid-range result in the UK in 2026. Budget refurbishments start from £2,500; high-end bathrooms with premium sanitaryware and tiles cost £8,000–£15,000+. Always get a site visit and written quote — bathroom costs vary significantly based on layout, specification, and required plumbing work.
What is the cheapest way to refurbish a bathroom?
Keep the toilet in the same position (moving it is expensive), supply your own sanitaryware (saves 20–30% on materials), limit tiling to high-impact areas (around the shower and splashback), and keep the existing bath if it's structurally sound. A budget refit with entry-level fixtures and limited tiling can be done for £2,000–£3,000.
How long does a bathroom installation take?
A standard bathroom refurbishment takes 5–8 working days (1–1.5 weeks). This includes strip-out, first-fix plumbing, boarding and waterproofing, tiling, second-fix plumbing, and finishing. Complex projects — new en-suites, major layout changes, wet room conversions — take longer. You'll be without the bathroom throughout.
Should I get a fixed price or day rate for bathroom installation?
Fixed price is strongly recommended for bathroom installations. A fixed price protects you from scope creep and cost overruns, and most experienced bathroom plumbers will quote a fixed price after a site visit. Day-rate quotes leave you exposed to open-ended costs. Ensure the fixed price includes waste disposal and any agreed extras.
