Because bathrooms are wet and humid by nature, tile is often used to protect the walls and floor (and also add a wallop of style and character). The goal with many modern bathrooms is to allow natural light in without allowing much visibility of the room from outside. Ceramic tile patterns, like the one on the back wall, project natural light further into the space. The floors in this room are also tile, which is a smart material choice when using bathtubs like the one in this bathroom. Tile also comes in nonslip options, making this bathroom stylish and safe.
