Wallpaper in bathrooms can last anywhere from one to 10 years, depending on what type was used, how well it was installed, and the measures in place to reduce moisture and humidity levels. Opting for a more durable variety and taking all the necessary protective measures will get you closer to that longer lifespan.

No, you don’t always have to remove old wallpaper before applying a new layer. However, you should pull off the existing wallpaper if it’s cracked, peeling, or in poor condition. We’d also recommend against putting wallpaper over textured or dark-colored wallpaper because the old layer may be visible through the new one. In addition, if you try to hang new wallpaper over vinyl-coated wallpaper, the adhesive might not stick properly. 

To remove pre-pasted wallpaper, you’ll need to wet the wallpaper or steam it to loosen the paste on the back of the wallpaper. Spray the paper with water, then let it soak for 10 to 20 minutes. From there, you should be able to peel off the wallpaper. Then, you may need to follow up with a cleaning solution and a scraper to remove any remaining wallpaper paste on the walls.

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.
