Six-inch square porcelain pool tile — fewer grout joints and faster to set over large areas.
6x6 is the practical choice for long straight waterlines, raised walls and spillways. One 6x6 covers the same ground as thirty-six 1x1 chips, so there is far less grout to install and far less to clean later. Porcelain also costs less per square foot than glass mosaic and is more forgiving of a rough substrate. Sold by the 11 sq ft box, 5/16" (8 mm) thick, frost proof and rated for chlorinated and saltwater pools. $4.99 samples.
