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.

One of the biggest downsides to peel-and-stick wallpaper is that it doesn't last as long as traditional wallpaper. Its lifespan depends on several factors, including the quality of the paper, proper wall preparation and application, and the room's conditions. As a general rule, peel-and-stick wallpaper can last for at least five years, but this can vary significantly. Budget products may only last about 3 years, while higher-quality products can stay up for 7 years or more in ideal conditions. Factors that can shorten its lifespan include high humidity (such as in a bathroom), dirty walls, and low-quality paper. If used on flooring, expect it to last only 1 to 3 years unless sealed. However, the shorter lifespan can be seen as a positive, making it a great choice for people who enjoy switching up their interiors more frequently.

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.

The cost varies from $1 to $3 per square foot, depending on the type of wallpaper, the wall condition, and the labor involved.
