It is one of the first questions every homeowner asks before starting a project: how much does a new bathroom cost? The honest answer is that it depends on the size of the room, the quality of the fittings, and how much the layout needs to change. A straightforward refresh in an existing footprint costs far less than a full reconfiguration with moved plumbing and a new suite.
This guide breaks down real UK price ranges for 2026/27, shows what separates a budget job from a premium one, and explains where the money actually goes once work begins. We have also included a look at pricing here in Surrey and the South East, where labour rates and property types can shift the numbers a little from the national average.
New bathroom cost in 2026/27
Prices below are supply and installation combined, based on a like-for-like or moderately reconfigured layout in an average UK home. Older properties, tricky access, or a full room reshuffle will push costs towards the top of each range.
- Cloakroom or WC refresh: £1,500 to £3,000
- Small en-suite (shower, WC, basin): £4,000 to £7,000
- Standard family bathroom (bath, shower, WC, basin): £6,000 to £10,000
- Large or L-shaped bathroom: £9,000 to £15,000
- Wet room conversion: £4,500 to £12,000
- Luxury or bespoke bathroom: £15,000 to £25,000+
If a level access shower is on your list, our Wet Rooms Explained guide covers wet room costs in more detail, including what pushes a project towards the higher end of that range.
Budget vs mid-range vs premium
Two bathrooms of exactly the same size can cost wildly different amounts, and the difference almost always comes down to the tier of fittings and finish rather than the layout itself.
- Budget (£4,000 to £6,000): standard white suite, budget tiles, off-the-shelf shower enclosure, basic tap and shower fittings.
- Mid-range (£7,000 to £12,000): named-brand suite, porcelain tiles, glass shower screen, upgraded storage, chrome or brushed finishes.
- Premium (£13,000 and up): designer sanitaryware, large-format or bespoke tiling, freestanding bath, underfloor heating, custom joinery.
It is worth saying that spending more does not automatically mean a better result. A well-planned mid-range bathroom, fitted properly, will usually outlast and outperform a premium suite installed badly. The fitting and waterproofing matter just as much as the products themselves.
If accessibility is part of the brief, the numbers shift again. Our accessible and walk-in bath options page has typical walk-in bath pricing and what tends to affect it, whichever tier you are working to.
Where the money goes: labour, tiling, suite & plumbing
When homeowners see a total quote, the biggest surprise is usually how much of it is labour rather than products. As a rough guide, this is how a typical bathroom budget breaks down:
- Labour: around 35 to 40 percent of the total. This covers plumbing, electrics, tiling, plastering and fitting, and is the single biggest line item on most jobs.
- Sanitaryware and suite: around 20 to 25 percent, covering the bath or shower tray, toilet, basin and taps.
- Tiling materials: around 15 percent, though this can rise sharply with large-format porcelain, natural stone or bespoke patterns.
- Plumbing and electrical materials: around 10 to 15 percent, including pipework, wiring, extractor fans and any boiler or pump changes.
- Extras and finishing: the remaining 10 percent or so, covering things like underfloor heating, heated towel rails, mirrors and lighting.
Hidden costs tend to appear when a project uncovers something unexpected, such as old pipework that needs replacing or a subfloor that is not level. Building in a contingency of around 10 percent of your total budget is sensible for any bathroom, however well planned.
Bathroom costs in Surrey & the South East
National averages are a useful starting point, but they rarely tell the full story for homeowners in Surrey and the wider South East. Labour rates here tend to sit a little above the UK average, and many of the properties we work on, particularly in areas like Caterham, Reigate and Oxted, are older builds with original pipework, uneven floors or period features that need careful handling.
That said, the region also has a strong resale market for well-finished bathrooms, so a properly specified mid-range or premium bathroom tends to hold its value well. Homeowners in this area often find that spending a little more on proper waterproofing and quality fittings pays off both day to day and at resale.
The best way to get an accurate figure for your own home is a proper assessment rather than a national estimate. Our bathroom design and installation service covers everything from initial design through to final fit, with a fixed quote once we have seen the space in person.
