TL;DR: What does a wet room cost in 2026?

Most UK homeowners spend between £4,000 and £12,000 on a wet room in 2026, with the average landing around £8,000 fully fitted, according to Checkatrade's 2026 cost guide. A compact, accessibility-focused wet room can start near £5,000, while a large, high-spec room with premium tiling and underfloor heating runs to £12,000 to £15,000 or more.

In Kent and the wider South East, expect to sit at the upper end of those national figures. Trade rates here run higher than the UK average, and because a wet room needs the entire floor tanked and re-graded, a bigger share of your budget goes on labour and waterproofing than with a standard bathroom refit.

What is a wet room?

A wet room is a fully waterproofed (or "tanked") bathroom where the shower area is open to the rest of the room, with no tray and often no screen. The whole floor is sealed and gently sloped towards a level drain, so water runs away safely instead of being contained in a cubicle. Because there is no step to climb over, a wet room is one of the most accessible bathroom layouts you can build, and it makes a small room feel far larger.

That open, tanked design is exactly why a wet room costs more to install than a like-for-like bathroom. The waterproofing and floor grading are skilled jobs that have to be done right the first time.

How much does a wet room cost in the UK in 2026?

Here are the typical all-in prices for a fully fitted wet room in 2026, including waterproofing, drainage, tiling and installation, based on current data from Checkatrade and MyJobQuote:

Typical 2026 cost (supplied and fitted)
What you get

A wet room is not simply a shower swap. The moment the floor has to be dug out or re-built to create the fall towards the drain, or an upstairs timber floor needs strengthening, labour rises and you move up a tier. Ground-floor rooms with solid concrete floors are usually the most straightforward and the most affordable to convert.

What is actually included in the cost of a wet room?

This is where a lot of online estimates fall down. The shower fittings are only part of the story. A realistic budget needs to cover stripping out the old bathroom, tanking the floor and walls, forming the drainage fall, tiling and finishing. Here is a typical breakdown of where the money goes, drawing on 2026 figures from Checkatrade:

 
 
Element
What to budget (2026)
Strip out old bathroom
£250 to £600
Waterproofing / tanking system
£500 to £1,500
Drainage and floor grading
£500 to £1,200
Wall and floor tiling
£1,000 to £3,000
Shower, screen and brassware
£600 to £2,500
Plumbing (first and second fix)
£1,000 to £2,500
Electrics and waterproof lighting
£400 to £900
Underfloor heating (optional)
around £100 per square metre
Labour (day rate)
£200 to £320 per day

Add those up and you can see how a "simple" wet room climbs past £6,000 before anyone has chosen a tile. That is completely normal, and it is why a fixed, itemised quote matters so much. When everything is designed, supplied and installed by one team, you avoid the classic trap of a cheap headline price that balloons once the tiler, plumber, electrician and waterproofing specialist all invoice separately.

How much does an accessible or disabled wet room cost?

Accessibility is one of the most common reasons homeowners in Kent choose a wet room, and it is an area where the numbers work differently. The average cost of an accessibility-focused, disabled wet room is around £5,000 according to Checkatrade, and there is important financial help available.

If the wet room is being installed for someone with a long-term illness or disability, the installation and specialist products can qualify for VAT relief, charged at 0 percent rather than the standard rate, as set out by HMRC. On top of that, homeowners in England and Wales may be able to apply to their local council for a Disabled Facilities Grant of up to £30,000 towards essential adaptations, subject to a means test, as explained by Citizens Advice. It is always worth speaking to Maidstone Borough Council or Kent County Council before you commit, so you know what support you qualify for.

How long does a wet room take to install?

A typical wet room takes around 4 to 7 days to install from strip-out to grouting, depending on the size of the room, the amount of tiling and whether the floor needs structural work. The waterproofing also needs curing time before tiling, which is one reason wet rooms take longer than a straight shower swap. If it is your only bathroom, plan for an alternative place to wash while the work is underway.

Is a wet room worth it?

For the right home, yes. A well-built wet room adds a clean, contemporary feel, makes a small or awkward bathroom far more usable, and future-proofs a home for step-free living, which is increasingly attractive to buyers. It can also add value at resale when finished to a good standard. The key is professional waterproofing. A wet room that leaks is expensive to put right, so this is not a project to hand to the cheapest quote or a weekend DIY attempt. Get the tanking right and a wet room will serve you well for decades.

Frequently asked questions

How much does a wet room cost in 2026? A wet room in the UK typically costs £4,000 to £12,000 fully fitted in 2026, averaging around £8,000. In Kent, mid-range projects usually land between £7,000 and £10,000, with compact accessibility wet rooms from around £5,000.

Is a wet room cheaper than a walk-in shower? No. A walk-in shower is usually £1,500 to £2,000 cheaper than a full wet room, because only the shower zone is waterproofed rather than the entire floor. A wet room costs more but offers fully level, step-free access.

Do wet rooms leak? A properly tanked wet room installed by professionals should not leak. Leaks almost always come from poor or rushed waterproofing, which is why the tanking system and drainage fall must be installed correctly and given time to cure before tiling.

Can I get VAT relief or a grant for a wet room? If the wet room is for someone with a long-term illness or disability, the work can qualify for VAT relief at 0 percent, and you may be able to apply for a Disabled Facilities Grant of up to £30,000 through your local council in England and Wales, subject to a means test.

How long does it take to install a wet room? Most wet rooms take 4 to 7 days to install, allowing time for waterproofing to cure before tiling. Larger rooms or those needing structural floor work can take longer.

Do wet rooms add value to your home? A well-built wet room finished to a good standard can add value and appeal, especially as step-free, accessible bathrooms become more sought after. The quality of the waterproofing and finish is what protects that value.
