What is a wet room?

A wet room is a showering space that is fully tiled and can include a glass screen to prevent spray from reaching every corner. If space is tight, you can still create a wet room look with a slim, flush shower tray. A wet room will take your showering experience to a whole new level where the design is only limited by the bathroom walls. This room, which will include a basin and WC, will be tanked to make it completely waterproof with adequate water drainage, such as a shower floor former or sub-floor, which will be tiled over.

Benefits of a wet room

They not only look incredibly stylish and ultra modern, but a luxury wet room offers a flexible alternative to the standard bathroom. Choose a wall-hung sink and WC and they will be even easier to keep clean and can instantly add value to your home. Wet rooms make the perfect choice for a small bathroom, as removing the bath will create more space and suit children, older people and those with mobility issues as they are easily accessible.

How to make a wet room

It’s best to employ a specialist company who can design and create your wet room for you. If you choose a ground floor or basement area, your sub-floor is likely to be solid. However, you may need to strengthen joists with waterproof plywood if you choose an upper floor level. A bathroom expert will visit your home and explain your options to you.

Making the slope

A slope will need to be created which will channel the water into a drain. A sub-floor made from special plywood can be used, a pre-formed shower tray can be set into the floor and tiled over or you could choose a giant pre-formed tray, which fits across the floor and will slope towards the drain. Impermeable sheeting, a sealant or prefabricated water-resistant boarding should keep your wet room waterproof.

Access Tray for a wet room

Other wet room considerations


The floor covering you choose is an important element to consider to create a wet room, which will not only look the part but offer durability and stand the test of time. Non-porous tiles or sheet vinyl, for example, will work, but make sure you choose non-slip tiles underfoot. Don’t forget to fit a high-performance extractor fan (your wet room specialist will help you) and perhaps think about under-floor heating, which will keep tiles warm underfoot and will dry water on the floor far quicker. A glass screen will make a perfect splash barrier too.
