Lush 1x4 subway tile "Vapor" is our most popular blue shade, a very pale, light blue. This glass subway tile is ideal for any wall application including kitchen backsplash tile, bathroom tile, fireplace tile and pool tile. The skinny subway tile is laid in a modern stacked or straight joint and comes mesh mounted by the square foot sheet. It can be laid either vertically or horizontally. This tile is easy to install in wet areas as well as dry, and it is well-suited for interior tile and exterior tile applications.
