Material: Unlike cheaper stone versions, this tile is made in Portugal with two types of marble, gold-flecked Italian Calacatta and soft-black Spanish nero.
Design: Hewing closely to historic basketweave, with small black squares, this version has crisp edges and tight grout lines. Polishing gives this marble a light-reflecting shine.
Care: Clean with mild soap and water. Marble (even if sealed) can be damaged by acidic cleansers, which eat into the calcite crystal. Abrasives, including shoe grit, sanded grout, and some cleansing powders, can scratch the finish.
TOH Pro Tip: Mark Ferrante, This Old House Tile contractor says, "Basketweave tile, especially in marble, is tricky to install, so before you decide which one to buy, ask an experienced tile setter how much it will cost to put down."
