Bathrooms are a great place to test out your love for patterns as they tend to have less furniture - hence you have more of a “blank canvas” to work with.
You might be worried about the humidity in a bathroom, but if it is well ventilated, and you are using a good quality wallpaper, it will be absolutely fine. If you are still a little nervous, use some tiling in an area prone to splashing - OR you can try some matching or contrasting wooden panelling to create a very sleek look.
As a result, your tiny or huge bathroom could become your favourite room in the house yet…. Just choose a wallpaper which gives you a sense of happy calm - and away you go.
