Yes, with a few caveats. Moisture is the enemy of most traditional wallpapers, so you’ll want to choose a variety made of vinyl, which resists damage from water. You’ll also first need to apply a mold-resistant layer of wallpaper primer, and use mold-resistant paste for the application. For an extra durable layer of protection, consider sealing the wallpaper with a protective finish, like acrylic varnish, or even covering the paper with acrylic sheets. Remember that with a bold pattern, a little can go a long way, so consider using wallpaper as an accent on a backsplash.
