Coral Stone Beige is a 12" x 24" porcelain tile. The face carries the movement of quarried stone. A glaze is fired onto the body, which is what carries the colour and pattern. A PEI 3 rating suits any residential floor. It carries an R9 slip rating, normal for a dry interior floor. It is frost resistant, so it can run from an interior floor onto a covered porch or patio. A box holds 8 pieces and covers 15.5 square feet. Made in Spain.
