The pros of wallpaper include its durability and longer lifespan than paint, as well as its versatility. The durability can translate to lower long-term costs for upkeep and replacement, and the versatility means you have more options for customizing rooms in your home. Some downsides include that it’s difficult to remove, it’s not ideal for rooms or areas exposed to high moisture content or sun exposure, and it’s tricky to install. A professional wallpaper hanger can help mitigate these issues, though, by installing it properly and in areas suitable for wallpaper.

Both paint and wallpaper can work in a bathroom, provided you choose high-quality products in either category. Washable vinyl wallpapers can stand up to bathroom humidity without peeling, as can semi-gloss or gloss paint finishes. However, if you’re someone who likes to redecorate often, paint may make it easier to change colors or designs more quickly. If you want full humidity protection and cleanability, tile or stone works better.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

Yes, but professional services ensure secure installation, accurate leveling, and protection against wall damage, especially for heavy or valuable items.
