Hanoi Blue Night is a 2.5" x 8" ceramic tile from Centura's Hanoi range. Wall installation is the rating here, so backsplashes and shower surrounds are in scope and floors are not. One box contains 38 pieces, enough for 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.
