I purchased this tile for my bathroom floor to be laid in a herringbone pattern. I couldn’t believe how hard it was to find smaller floor tile of this size. I had originally wanted slate tile but was worried about the maintenance / wear so I decided to go with this porcelain tile instead. I ordered samples of the Niello and Cobalto colors (see picture). The Cobalto is lighter and has more blue hues while the Niello is a charcoal color with brown undertones. Both are beautiful but I decided to go with the Niello as it more closely matched the rest of our finishes.
