If you want to use Lim & Handtryck's wallpapers in wet areas, we recommend post-treating them in some way. For instance, it's a good idea to varnish the wallpapers to protect them from splashes and moisture. However, be aware that the wallpaper's colors will darken slightly due to the varnish. We do not recommend wallpapering the most exposed areas of the bathroom, such as in the shower or behind the toilet.
