Monza Spring is a 24" x 24" porcelain tile with rectified edges, which allows a tighter grout joint. The face carries the even, slightly clouded tone of poured concrete. A matte surface holds light rather than reflecting it. A PEI 3 rating suits any residential floor. It is frost resistant, so it can run from an interior floor onto a covered porch or patio. A box holds 4 pieces and covers 15.5 square feet. Made in Malaysia.
