Time Marble Taupe is a 12" x 24" porcelain tile with rectified edges, which allows a tighter grout joint. The face carries the veining of natural marble. A matte surface holds light rather than reflecting it. A PEI 3 rating suits any residential floor. It carries an R11 slip rating, which holds up in wet areas and entrances. 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 China.
