A full bathroom installation typically costs between £3,000 and £8,000 for most UK homes, though your final bill will depend on the size of your bathroom, the quality of fittings you choose, and the extent of work required. A basic refresh with budget fittings might come in around £3,000, whilst a luxury bathroom with high-end materials and underfloor heating could easily exceed £10,000.
Breaking Down the Costs: Labour vs Materials
Labour generally accounts for 40-60% of your total bathroom cost. A typical installation takes 5-10 days, with bathroom fitters charging between £150-£250 per day depending on your location and their experience level. London and the South East tend to be at the higher end of this range.
You'll need to budget for several different tradespeople unless you hire a bathroom fitter who manages the entire project. Most installations require a plumber, electrician, tiler, and possibly a plasterer or carpenter. This coordination is why many homeowners opt for a specialist bathroom fitter who can organise all trades and take responsibility for the complete job.
Materials vary wildly in price. A basic white bathroom suite (toilet, basin, and bath) starts around £300-£500, whilst designer brands can cost £2,000-£5,000 or more. Mid-range suites offering good quality and style typically fall between £800-£1,500.
What Affects the Price of Your Bathroom Installation?
The size and layout of your bathroom makes a significant difference. A small ensuite (2-3 square metres) costs considerably less than a family bathroom (4-6 square metres). If you're keeping the existing layout with plumbing in the same positions, you'll save money. Moving toilets, sinks, or showers to different walls requires rerouting pipes and can add £500-£1,500 to your costs.
The condition of your existing bathroom matters too. If walls and floors are in good shape, you'll simply need to fit new items. However, if you're dealing with rot, poor plasterwork, or outdated wiring, remedial work adds both time and expense. It's worth being realistic about this from the start rather than discovering problems mid-project.
Your choice of fixtures and finishes significantly impacts costs. Stick with a simple suite, standard tiles at £15-£25 per square metre, and chrome fittings for a budget-friendly option. Choose large-format tiles, brassware, underfloor heating, or a walk-in shower enclosure, and costs rise accordingly.
Typical Costs for Different Bathroom Types
A basic refresh of a small bathroom with budget fittings, keeping the existing layout, typically costs £3,000-£4,500. This includes a white suite, standard tiles, basic shower over bath, and straightforward installation.
A standard family bathroom replacement with mid-range fittings runs £5,000-£7,000. You'll get better quality fixtures, a separate shower enclosure, more attractive tiles, and improved lighting.
A high-spec bathroom with luxury fittings, underfloor heating, and premium tiles costs £8,000-£12,000 or more. This might include a freestanding bath, large walk-in shower, designer tiles, heated towel rails, and specialist lighting.
Small ensuites typically cost less—budget around £2,500-£5,000 depending on specifications. Cloakrooms are simpler still, often completed for £1,500-£3,000 with just a toilet and basin to install.
Additional Costs to Consider
Don't forget these often-overlooked expenses when budgeting for your new bathroom:
- Waste removal and skip hire: £200-£400
- Building regulations compliance and inspections: £200-£500
- Upgrading electrics to current regulations: £300-£800
- Treating damp or improving ventilation: £200-£600
- Redecoration after installation: £300-£600
- Accessories like mirrors, cabinets, and towel rails: £200-£800
How to Get the Best Value for Your Money
Getting quotes from at least three different bathroom fitters helps you understand the going rate and spot any outliers. Be specific about exactly what you want included—some quotes cover everything, whilst others exclude items like tiling, decoration, or waste removal.
Consider whether you want to supply your own materials or let the fitter source them. Buying your own suite and tiles can save money, but professionals often get trade discounts that narrow the gap. More importantly, if they supply materials, they're responsible if anything's wrong or damaged.
Timing matters too. Bathroom fitters are often quieter in January and February, and some offer better rates during these periods. However, never choose a tradesperson on price alone—check reviews, ask to see previous work, and ensure they have proper insurance and relevant qualifications.
A well-planned bathroom should last 10-15 years, so it's worth investing in decent quality, particularly for items that are difficult to replace later like pipework, waterproofing, and the shower enclosure. You can always upgrade towel rails and accessories more easily than you can fix a leaking shower tray hidden under tiles.
