Types of Wet Room Installation

Best for: Small bathrooms and compact ensuites

A larger shared bathroom wet room usually includes broader tiling coverage and a more developed storage and screen layout.
Pros

- Can feel more open than a standard shower enclosure
- Flexible layout potential

The biggest price differences usually come down to room size, drainage changes, waterproofing complexity, and the specification of tiling and screens.
What Affects the Cost
- Room size and amount of tiling required

- Tanking and waterproofing requirements
- Choice of tiles, screens, and brassware

Frequently Asked Questions
How much does a wet room cost in the UK?
A smaller basic wet room can start around the mid-thousands, while larger or higher-spec projects can rise well beyond that.
Why are wet rooms expensive?
Much of the cost comes from waterproofing, drainage work, preparation, and tiling rather than just the visible fixtures.
Is a wet room more expensive than a normal shower room?
Usually yes, because the waterproofing and floor preparation are generally more involved.
How long does wet room installation take?
Many projects take around one to two weeks, depending on drying times, tiling, and whether pipework is moved.
Can any bathroom be turned into a wet room?
Many can, but the layout, drainage position, and subfloor condition all affect practicality and cost.
Is tanking always necessary in a wet room?
A proper waterproofing system is usually essential because the room needs protection well beyond a standard shower enclosure.
