@Frances2 – Your question brings up a point: There are two things that are currently referred to as “wet walls” when it comes to construction and remodeling. One is described in the article above, and the other is what you’re asking about – a decorative, protective covering for a wall that will often become wet.
Since wet walls are all about efficiency and easy access to plumbing, the trend is moving towards wet wall panels, instead of traditional bathroom tiles. The panels can be installed quite easily, and removed at a later time without all the mess created by the destruction of a tiled wall.
Wet wall panels are perfect for you, since you want elegance in your new bathroom. There are several companies that manufacture elegant panels. They can look like natural stone, polished metal, or bear intricate designs.
An expert in interior design should be able to help you choose the right wet wall panels for your project. They come in different sizes and some manufacturers offer interlocking panels for covering larger areas. An interior designer would know which company sells the panels that suit your needs.
