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.

Hiring a professional wallpaper hanger is usually a worthwhile idea because, while the application of wallpaper itself is easy, getting the finished product to look good is complicated and takes a lot of practice and patience. A professional wallpaper hanger will not only be able to hang your wallpaper seamlessly, but they will also get an even application of wallpaper paste to avoid bubbling and imperfections immediately and over time. Plus, they can provide their professional opinion on whether to remove or wallpaper over an existing layer of wallpaper.

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.

The average cost to install or hang wallpaper is around $575 per room or project, with typical prices ranging from $200 to $1,500. Costs can be higher for custom or luxury products. Since project size varies, it's often helpful to estimate labor costs per square foot, which generally fall between $1 and $7, with an average of $4 per square foot. The total cost depends on several factors, including the quality and type of wallpaper, the size and type of the room, and whether old wallpaper must be removed first. Opting for less expensive materials like peel-and-stick wallpaper or choosing to do the installation yourself can lower the overall cost. For the most accurate estimate, it is best to have a professional inspect the space and provide a quote.
