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.

Peel-and-stick wallpaper is designed to be removed without damaging walls, making it a good choice for renters or temporary design changes. However, damage to paint or drywall can occur under certain conditions. To prevent issues, the wall surface must be properly prepared before application—it should be clean, smooth, dry, and correctly primed or painted. Applying wallpaper to a freshly painted surface can cause the paint to peel off during removal. Additionally, removing the wallpaper too quickly or aggressively can also cause damage. For best results, always follow the manufacturer's instructions for both application and removal.

Painting over wood paneling is an option that can save you money and time. However, if you go this route, the style and texture of the wood you paint over will still be evident. Painting over paneling is an excellent way to modernize an otherwise outdated aesthetic. Instead of removing wood panels, consider painting them a bright color–like white or ivory. This is essentially wainscoting, but without any of the required installation. 

To remove adhesive-backed wallpaper, you’ll need to soften the adhesive before you try peeling the wallpaper off the walls. You may wonder whether peel-and-stick wallpaper damages walls. It can depend on the removal method. Make sure to be patient and consider using a steamer, hair dryer, or adhesive remover to carefully take down adhesive-backed wallpaper.
