Riverland, a collection of porcelain stoneware from Century, takes its inspiration from agate, a stone with delicate streaks of color. Available in 30 by 60, 60 by 60 and 50 by 100 centimeter sizes with natural or honed finishes, Riverland allows designers to customize both floors and walls in residential and commercial settings. The tiles are available in white, black, brown and gray, and are certified by Bureau Veritas to contain at least 40 percent recyclate.
