These tiles, veneered in Eucalyptus Burl, measure 5-1/2" x 5-1/2" x 3/8" thick and are designed for use in backsplashes and accent walls. They are veneered over a stable and water resistant plywood backer, can be cut with basic woodworking tools and can be installed and grouted like regular tiles. The edges must be finished with some sort of trim such as a Kerdi Schluter molding. Each box comes with installation instructions. I have four boxes currently available, three boxes containing 15 tiles covering a total of 3.3 sq. ft and one box containing 13 tiles covering a total of 2.9 sq. ft.
