Perfectly sized for a small bar or prep area in the kitchen, the Blanco Rondo Silgrant II Bar Sink is compact but big on durability. The sink is manufactured out of SILGRANIT, a revolutionary composite material made out of 80 percent solid granite for durability and a natural stone look. SILGRANIT beats natural stone in terms of ability to resist damage due to heat, scratching, alkalis, and acids. The non-staining material is also very simple to keep clean.
