Flow Peacock Green is a 3" x 12" porcelain tile. The pattern carries a room on its own, which is why it is usually run on one wall rather than all four. Porcelain is pressed and fired denser than ceramic, which is what lets it take water, frost and daily traffic. Porcelain of this density suits floors and walls through the home. The plank shape can run in a straight lay or a herringbone to draw the eye down a room. Order the area you are covering plus about ten percent for cuts and waste.
