If you would like to hang a wallpaper in a bathroom or water closet, you must select our self adhesive vinyl material. As long as the room will not have consistent high humidity (i.e. not a room that has regular showers every day) and is not constantly splashed with water, then the wallpaper should be fine. Our self adhesive vinyl material can be lightly splashed and wiped down with a damp cloth to clean. However, do not let your wallpaper get continually wet or sit in water otherwise the adhesive will soften and weaken and the wallpaper will begin to peel. Please note that we cannot predict or accurately know exactly how much water is being splashed onto your wallpaper in a bathroom or water closet environment, and as such we do not offer any guarantee or free repair service for this material installed within these types of rooms.
