The joints are the central feature on these white-body ceramic tiles from Italian manufacturer Ceramica Sant’Agostino. Emphasis on the joints and connection between them adds a decorative, architectural element to typically functional tile. Five different structure types are offered, ranging from no joints to joints on all four sides, and all structures are 12-by-12 inches. Colors include white, yellow, grey, and greige. The manufacturer offers matte and polished finishes.
