These are wooden tiles designed for a backsplash or accent wall. Measuring 6" x 6" x 1/2" thick, they made of a water-resistant substrate veneered in pommele figured bosse cedar. They can worked with standard woodworking tools, adhered to walls with silicone or construction adhesive, and grouted with normal tile grout. The edges must be finished with some sort of trim such as a Kerdi Schluter molding. Each box comes with installation instructions. I have two boxes currently available, each box containing 11 tiles that cover 2.75 sq. ft.
