Art glass or stained glass in the master bath can be used to ensure privacy or obscure an unattractive exterior view while still allowing light to flow into your bath area. Stained glass can be colorful or have no color at all. Colorless glass comes in many textures which can be used to obscure visability or be used to obscure a partial view. For example, use art glass for the bottom half of a window and allow you to enjoy the view from the upper portion of the window. Why use glass block when you can enjoy a beautiful installation of art glass instead!
