Wall panels offer functional and aesthetic benefits. From a practical standpoint, panels can improve your home's insulation and energy efficiency, especially if you opt for solid wood panels. They can also help protect your existing wall.

Aesthetically, wall panels have a knack for adding dynamic texture, warmth, and sophistication to a room. And thanks to their many different shapes, sizes, and styles, wall panels can elevate a wide variety of home designs.

Finally, it’s relatively easy to cover wall panels, so you have some flexibility if you end up not liking the look over time.

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.

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. 

Walls should be as smooth as possible before applying peel-and-stick wallpaper. Although you technically can apply wallpaper on textured walls, the peel-and-stick variety won’t last long without a clean, smooth surface for the adhesive to stick to. If you have textured walls, consult a pro about removing the textured finish before moving forward with wallpaper.
