A wet room is the ultimate modern bathroom upgrade. It offers a sleek, open-plan design that is practical, accessible, and adds serious value to your property. By removing the shower tray and waterproofing the entire floor, you create a spa-like sanctuary right in your own home.
However, transforming a standard bathroom into a fully watertight wet room requires specialist skills and materials. In 2026, the cost of installing a wet room varies depending on the size of your space and the quality of finish you desire. This guide breaks down the essential costs to help you budget with confidence.
How much does a wet room cost?
The price of a wet room is typically higher than a standard bathroom renovation due to the necessary waterproofing (tanking) and drainage work.
On average, the total wet room cost in the UK ranges between £4,000 and £10,000.
- Budget wet room (small ensuite): £4,000 – £6,000
- Mid-range wet room: £6,000 – £9,000
- Luxury wet room (high-end stone & fixtures): £10,000 – £15,000+
These prices usually include the removal of your old suite, all materials, and the labour for installation.
What is the cost of wet room installation?
To understand where your money goes, it helps to look at the individual components. The cost of installing a wet room is split between specialist labour and materials.
Waterproofing and drainage
This is the most critical part of the build. Your fitter must create a gradient in the floor so water flows to a drain, then seal the entire room to prevent leaks.
- Tanking kit and membranes: £500 – £1,200
- Drainage systems: £300 – £800
Tiling and flooring
Floor-to-ceiling tiling is common in wet rooms. You need non-slip tiles for safety, and costs vary significantly based on the material.
- Ceramic tiles: £30 per m²
- Porcelain tiles: £50 per m²
- Natural stone: £70+ per m²
- Tiling labour: £50 – £100 per m²
Labour costs
Installing a wet room is a complex job that may involve plumbers, tilers, and electricians.
- General labour: £200 – £300 per day per tradesperson
- Total labour cost: £2,500 – £5,000
How much does a wet room cost for accessible needs?
Wet rooms are a popular choice for people with limited mobility because they offer level, step-free access. An accessible wet room often requires specific safety features.
- Accessible wet room starts from: £5,000
- Grab rails and seats: £100 – £300 extra
- Anti-slip safety flooring: £25 – £70 per m²
Are there extra costs to consider?
When calculating how much a wet room costs, remember to factor in potential upgrades that improve comfort and functionality.
- Underfloor heating: Essential for drying the floor quickly and keeping tiles warm. Expect to pay £300 – £400 for a typical room.
- Ventilation: A powerful extractor fan is vital to stop dampness. Budget £150 – £300 for installation.
- Shower screen: While not strictly necessary, a glass screen prevents water from spraying onto towels and toilets. These cost between £280 and £350.
