Wet Room Installation Cost
The average cost of a wet room installation is around £4,000 to £7,000 and will usually take around 4 to 7 days.
Installing a wet room is not an easy job, and there are a lot of different parts to it. From tanking the bathroom to prevent water leaking, to tiling and rerouting pipework — it is not a typical DIY job, which is why most homeowners choose to hire professional wet room installers.

How much should I be paying for the labour, removing my current bathroom, disposing of it, making good, and installing the new bathroom suite?
"On average, a good tradesman can perhaps charge you a daily rate between £180 and £220 per day or price work, which can be anything between £1500 to £2500. However, this depends on the work required."
Wet Room Installation Supply Only Costs
A professional wet room installation can involve a number of different trades, including plumbers, tilers, bathroom fitters, and perhaps electricians, which is why most homeowners choose a complete installation package, rather than trying to coordinate everything themselves.
However, if you want to purchase all the materials yourself and hire the different trades to fit them separately, perhaps to reduce costs or because you want to manage the project yourself, the table below shows the typical cost of the materials you'll need for a wet room installation.
| Job Description | Cost |
|---|---|
| Tanking shower kit | £130–£180 |
| Shower tray former | £450–£550 |
| Wet room drain / waste kit | £50–£130 |
| Shower | £400–£500 |
| Shower screen | £280–£320 |
| Toilet | £150–£400 |
| Basin | £80–£300 |
| Basin taps | £50–£200 |
| Tiles | £700–£850 |
| Tile adhesive | £60–£80 |
| Grout | £35–£50 |
| Spacers | £18–£25 |
Additional Wet Room Costs
There are several additional costs that you may need to consider for a wet room installation. A number of extras can be added to improve a basic wet room.
These additional costs can include:
- Full-room tanking (additional waterproofing) – £300 – £800
- Underfloor heating - £300 – £400
- Bath installation - £500 – £700
- Recessed shower shelves / niches – £150 – £400
- Spotlights or downlights - £300 – £500
- Skip hire for waste removal - £60 – £130
- Heated towel rail installation - £430
Hidden Costs to Budget for in a Wet Room Installation
Some wet rooms come in on budget, but quotes can increase once the existing bathroom is stripped out. These are some of the most common additional costs:
- Bathroom floor repairs or levelling — especially with timber floors that need strengthening before waterproofing.
- Structural work to reinforce the floor before tanking is installed.
- Moving drainage or creating enough fall to prevent standing water.
- Upgraded ventilation, including a new extractor fan and ducting to reduce moisture build-up.
- Electrical work for lighting or electric underfloor heating mats.
- Repairs to hidden water damage discovered during removal of old tiles or flooring.
These hidden costs are easier to budget for if your installer checks the bathroom floor, drainage position, and ventilation before work starts.
Looking to convert our spare bathroom in our extension to a wet floor bathroom. Is this possible and what would an estimated price be?
"That demolition job and installation of a new wet bathroom will cost £5,800."
Disabled Wet Room Costs
A disabled-access wet room can cost more than a standard wet room due to often needing additional safety and access features. A small disabled-access wet room installation typically costs around £4,950 for a standard conversion of an existing bathroom.
Prices can increase if structural work, specialist fixtures, or plumbing relocation are required.
Disabled Wet Room Cost Factors
- Additional space for turning and easier access.
- Grab rails, shower seats, and other assisted living products.
- Slip-resistant flooring to reduce the risk of falls.
- Wider doors or layout changes that require extra building work.
Grants And VAT Relief
If you need a wet room because of a disability or long-term health condition, you may be eligible for a Disabled Facilities Grant (DFG) through your local council. Some bathroom adaptations may also qualify for VAT relief in certain circumstances.
Eligibility rules differ by local authority, so it’s best to contact your council directly to find out what support may be available.

What Impacts the Cost of a Wet Room Installation?
We've already looked at how the size and complexity of your project, as well as your location, can affect the cost of installing a wet room in your home. Below is a list of some of the other factors that can alter the total price you'll pay:
- Extent of the Job — The more complicated the job is, the longer you can expect it to take. Additional work, such as more pipework or intricate furnishings, can also result in the job taking longer. If the job takes longer or is more difficult, then you can expect to pay higher labour costs.
- Type and Quality of Furnishings — You may choose to have basic furnishings or more luxury furnishings, which will affect how much you’re going to pay for the entire job.
- Floor Type and Condition — The type and condition of the bathroom floor can affect the final wet room cost. Timber floors or uneven subfloors may need additional work before the wet room installation can begin. Floorboard repairs can cost around £200 to £800, depending on the extent of the damage.
- Drainage and Fall to the Drain — A wet room requires a correct fall so that water runs into the drain properly. If the drainage position is awkward or there isn't enough fall, installing a wet room can become more complex.
- How Much Plumbing Needs Moving — Plumbing costs can increase if pipework needs to be moved. Keeping the shower, toilet, and waste pipes in the same position is usually cheaper when installing a wet room, while relocating waste and water connections can add time and labour.
- Preparation Work — Removing old tiles and fittings, repairing walls, and levelling the floor can increase costs if this work isn't already done before installation.
How much would it cost to convert an 8’6” x 4’10” ensuite into a wet room, keeping the existing suite as much as possible?
"The biggest job is removing the existing shower cubicle and tray, then once out, lowering the waste pipes into the floor and installing a preformed wet room shower tray. After this, you can bring the remaining floor height up to meet said preformed shower tray and tank the room to ensure no leaks at all. Tile where required and reinstall the existing suite.
Relatively easy job for any wet room specialist and a budget of £1,500 to £2,000 including materials should be plenty."

Here’s a brief overview of the process you can expect when you hire an experienced professional to install your wet room:
Before the Job Starts
- Initial Survey & Design — The contractor will assess the space where you want your wet room installed, checking the walls and floors will allow for the correct drainage and ventilation. They will also work with you to design your wet room and choose the fixtures and finishes.
- Checking the Floor & Structure — The floor needs to be solid and level to be suitable for proper waterproofing, so your contractor will check this and make sure any weak spots are reinforced before work begins.
- Planning the Drainage & Plumbing — Planning the layout of the plumbing and drainage pipes is essential to make sure the wet room has the correct fall angles to make sure the water drains efficiently.
During the Job
- Preparing the Room — If converting a current bathroom, any previous bathroom fixtures and plumbing are removed, and the room is stripped back to a bare structure, ready for installation.
- Installing the Waterproofing (Tanking) — The space needs to be completely watertight, so specialist membranes and waterproofing products are applied to the floor and walls.
- Installing the Drain & Flooring — Using a wet room former or a carefully formed screed base, the floor around the drain is shaped to create the necessary slope into the drain, and the rest of the wet room floor is laid.
- Installing the Plumbing & Fixtures — The chosen fixtures, i.e. the shower, toilet, and basin, are all plumbed in, and other features such as underfloor heating mats or underfloor heating systems are connected.
After the Job
- Sealing & Finishing Touches — All the grouting and silicone are applied to complete the waterproofing and final checks for any leaks are carried out.
- Ventilation & Safety Checks — Checks are carried out to ensure the new wet room has adequate ventilation and the floor surfaces are slip-resistant.
- Certification & Guarantee — Finally, you should receive any appropriate guarantees and certification for the plumbing and electrical work, where applicable.
I have a reasonably large downstairs toilet that I'd like to turn into a wetroom. The room is approximately 2m x 2.5m. How much would I be looking at cost wise for the conversion?
"You would be looking in the region of about £5,000 depending on what materials and design you would like."
What Is the Cost of Wet Room Flooring?
There are several wet room flooring options to choose from. The right material will affect durability, slip resistance, and compatibility with underfloor heating.
Below is a list of the different types of wet room flooring and some information on each of the different types:
Tiled Flooring Cost
Tiled flooring is the most common option for a wet room. There is a wide range of designs available, making it easy to match your preferred style.
Tiled Wet Room Flooring: £30–£50 per m²
- Maintenance — Easy to clean with standard bathroom products.
- Durability — Hard-wearing and suitable for high-traffic bathrooms.
- Slip Resistance — Non-slip tiles can reduce the risk of falls.
- Compatibility — Works well with electric underfloor heating mats.
- Design Range — Available in large tiles, natural stone, and mosaic styles.
Vinyl Flooring Cost
Vinyl flooring is another popular wet room option. When installed correctly, it can act as a waterproof surface across the entire floor.
Vinyl Wet Room Flooring: £20–£40 per m²
- Maintenance — Simple to clean and maintain.
- Durability — Water-resistant and flexible.
- Slip Resistance — Often less slippery than some standard tiles.
- Installation — Can create a seamless finish with fewer joints.
- Cost — Generally more affordable than natural stone options.
Microcement Flooring Cost
Microcement creates a smooth, modern finish with no grout lines. It is often chosen for contemporary wet room designs.
Microcement Wet Room Flooring: £80–£120 per m²
- Maintenance — Easy to wipe clean due to its seamless surface.
- Durability — Hard-wearing when professionally applied.
- Finish — Creates a seamless finish with a modern design.
- Compatibility — Works well with underfloor heating systems.
- Design Options — Available in a range of colours, although fewer patterns than tiles.
What makes a good tile for a wet room?
"The most suitable types of tiles for a wet room floor are Porcelain, Natural Stone or Mosaic tiles. Because of there construction we do not recommend the use of ceramic tiles on a wet room floor, they are however perfect for the wet room walls."
Benefits of Installing a Wet Room
There are several benefits to a wet room. Here is a list of some of the main advantages of installing a wet room in your home:
- Adds a Touch of Luxury — The modern style of a wet room can add extra luxury to your home. There are many additional features that you can add to your wet room to make it feel even more luxurious such as underfloor heating or luxury décor.
- Completely Waterproof — When a wet room is installed correctly, it is entirely waterproof. This provides reassurance that water won’t leak through the walls or floor.
- Easy to Clean and Maintain — Wet rooms are deemed easier to clean than a traditional bathroom. This is particularly true when the room has a wall hung toilet and sink. This provides easy access for cleaning the floor.
- Increase the Value of Your Home — When you add a wet room to your home, it can increase the value of your home. For the best results, it is best to install a wet room as a second bathroom or to install a bath in it.
- Flexibility in Layout and Design — A wet room allows you to unleash your creativity as you can add many different design and décor elements based on your personal style.
- Provides Convenience and Safety — The level access of a shower in a wet room is a safe and practical option. Shower trays are usually finished with non-slip tiles which provide both safety and style.
Removing a Wet Room Cost
How much does it cost to change a wet room back to a bathroom?
You may want to remove a wet room to install a regular bathroom. If this is the case, it is quite a big job that is likely to cost around £6,600 on average, depending on the size of the room and the type of suite and décor.
To remove the wet room, you will need to remove the flooring and replace it with new flooring. You will also need to remove the shower and replace this with either a new shower or a bath, or a bath/shower mix.
Removing and replacing a wet room is a challenging job that is likely to take around 7-10 days. You will need to hire a professional company to handle this for you. When getting a quote for this, the contractor will usually include all of the different elements of the job, including the replacement process and waste removal.
Checklist: Hiring a Bathroom Fitter to Install a Wet Room

FAQs
What's the difference between a wet room and a bathroom?
A wet room is an entirely waterproofed, or tanked, bathroom with a shower area that is at the same level as the rest of the floor. A wet room requires specialist waterproofing and drainage to make sure there are no leaks or water damage.
Can any bathroom be converted into a wet room?
Most bathrooms can be converted into a wet room, although how challenging the project will be will depend on things like the amount of space, the floor construction, existing plumbing layout, and how much waterproofing is required. A wet room specialist will be able to assess whether your bathroom is suitable.
How small can a wet room be?
Wet rooms can be great for small bathrooms because they maximise use of the available floor space and even make the room seem bigger. A small wet room can be around 1.5m x 1m with enough space for a washbasin and toilet as well.
Do you need planning permission for a wet room?
You usually do not need to have planning permission for a wet room unless it is part of a new extension on your home, or your home is a listed building.
Do you need building regulations for a wet room?
Building regulations may apply if you are converting an existing room into a wet room or working on a new build, and the work involves structural changes or changes to drainage, ventilation, or electrical installations. Building regulations rules will vary from job to job, so it is best to seek advice. A professional wet room fitter will be able to create a plan for your new wet room. They will be able to advise and adhere to all of the relevant building regulations rules as needed for your particular project.
Do wet rooms add value to your home?
A professionally installed wet room is not only a stylish addition to your home, if it's done well, you could potentially add value to your home. It can also make your property more appealing to buyers when you decide to sell.
Can I install a wet room myself?
It is not recommended that you attempt a wet room installation yourself.
Installing a wet room is not an easy job, and hiring a qualified professional means they will have the tools, equipment, and expertise to complete the project to a high standard.
Do I need to tank a wet room?
No matter how good your tiling and grouting are, the changes in temperature and humidity can cause fine cracks which can allow water to leak through the walls or floor. This is why a wet room should be tanked. All tiling in wet areas of the wet room should be fully sealed with a waterproof membrane below them.
Is a wet room more expensive than a walk-in shower?
A wet room is generally more expensive than a walk-in shower. For a wet room, you can expect to pay between £4,000 and £7,000. In comparison, replacing a bath with a walk-in shower typically costs between £1,000 and £5,000, depending on the design and chosen finishes. For a more detailed breakdown, read our replace bath with a walk-in shower cost guide.
