Quick summary

To add a wet room to your home, expect to spend between £6,000 and £12,000 for a typical bathroom, with costs influenced by size, design, and materials. The project requires professional installation, including waterproofing and tiling, and usually takes several days. It’s suitable for most homes, but check local restrictions if in a listed building.

Forget the wet rooms you might have known as a kid, nowadays they’re taking over modern bathroom design, providing a space-saving and stylish feature for homes of all sizes to enjoy.

If you’re considering one for yourself, here’s everything you need to know…

What is a wet room?

Though the name suggests otherwise, a wet room doesn’t necessarily mean you need an entire room dedicated to them (though this is an option). In fact, all adding a wet room means is you have a shower area that doesn’t use a tray and is instead in an open, fully tiled space.

Their open design allows them to be installed in bathrooms big and small. However, for those wanting to keep them next to toilets, sinks and towel racks, it’s worthwhile adding a good screen to stop the spray from soaking your fixtures.
