Cromie is the first collection from Refin to use the company’s Ecosan24 treatment, which uses titanium dioxide and metallic elements to treat pollution, self-clean, and sanitize the tiles, much like competitor Casalgrade Padana’s Bios Self Cleaning Ceramics. The Cromie collection comprises four tile families—Polvere, Fango, Terra, and Tendenze—in a total of nine chromatic shades. All Refin collections meet Ecolabel certification standards, according to the manufacturer.
