Hanoi Wild Olive belongs to Centura's Hanoi range and measures 2.5" x 8". Wall installation is the rating here, so backsplashes and shower surrounds are in scope and floors are not. Boxes hold 38 pieces and cover 5.16 sq ft, or 0.1358 sq ft a piece. A ceramic body is lighter than porcelain and easier to cut on site, which is why it is the usual choice for walls and backsplashes.
