Yes, many types of peel-and-stick wallpaper can be used in bathrooms, especially those made of vinyl or polyester. However, its success depends heavily on the level of moisture and ventilation. In bathrooms with good ventilation, such as those with fans, it can be a durable option. Peel-and-stick wallpaper may not adhere as well as traditional wallpaper in very humid conditions. For bathrooms that see a lot of moisture, like a kids' bathroom or a full bath with a steamy shower and poor ventilation, even high-quality peel-and-stick wallpaper is likely to peel over time.

While many types of peel-and-stick wallpaper can be used in bathrooms, they may not adhere as well in humid environments as traditional wallpaper. For best results, choose a vinyl or polyester-based wallpaper, as these materials are more durable and water-resistant. Good ventilation is also crucial to reduce humidity from steamy showers. In bathrooms with high moisture and inadequate ventilation, even high-quality peel-and-stick wallpaper is likely to peel over time.

As long as the surface you’re putting the tile on is properly prepped, peel-and-stick backsplashes should stay on and last anywhere from 3 to 5 years. The best way to ensure the tile stays on is to sand down and clean the wall before applying your design.

You may end up with extra wallpaper once your project is finished. Hang on to that wallpaper, as you may need to use it to patch up areas that get damaged later on. If you have a lot of excess wallpaper, try getting creative with it. You can use it to line the inside of a cabinet or drawers, for example.
