How to Make a Wetroom Work in your Home

Wetrooms require skilled design and installation beyond that of a standard bathroom and if not done correctly can often result in leaks and other problems. The key to a successful wetroom installation is understanding the specific requirements at an early stage.

A wetroom is an open plan space and simply does away with the shower enclosure. In a wetroom the water drains away through the floor, which has a gentle gradient in the direction of the shower drain. Wetrooms provide the ideal way to create a sleek, contemporary look.

When is a wetroom not a good idea?

Before deciding if a wetroom is right for you there are some factors that will need to be considered. A wetroom can be a great way to make the most out of a medium sized bathroom but in a small space it means that everything will just get soaked when having a shower. In a small bathroom a wetroom screen can be fitted to protect items from getting covered in splashes of water.

Creating a wetroom is not a good idea if you want an easy bathroom makeover. Waterproofing or tanking the entire room is essential for the success of any wetroom installation and can be a costly job. Constructing, waterproofing and finishing the wetroom is a job that is always best left to a professional fitter.

How can a wetroom go wrong?

Leaking water is the main problem with a wetroom, this is because it hasn’t been tanked properly or the deck that a wetroom is constructed on isn’t built properly. Sometimes a wetroom isn’t successful is due to the layout of the bathroom, which can cause everything in the room to get soaking wet when showering.

Good drainage is essential

Ensuring that the water runs straight to the drain is the first step to getting a wetroom right. The floor in a wetroom needs to slope gradually into an even gradient.

The construction of the wetroom deck varies on whether you have a wooden or concrete floor. The gradient is normally built into a concrete floor in a new build. With wooden floors the space for the drain is cut out of the joists, then the waste can be fitted and a weather and boil proof plywood subfloor is fitted to the top of the joists to create a robust platform that can be tiled. A ready-made under tray is another option and can also be tiled over.

The entire room will then need to be tanked. If you have wooden floors they will need to be primed and a special tape applied to any joins or areas that can be penetrated. Floors and walls are covered with a waterproof membrane and the wetroom is then ready to tile.

How to keep a wetroom dry

Underfloor heating is highly recommended to ensure that your wetroom floor is kept dry. Stepping onto a warm floor feels very luxurious and a warm floor also means that puddles of water will quickly dry up. Good ventilation is also vital for keeping the room dry too.
