The Franke Single Bowl Undermount/Drop In Granite 10007 Sink are particularly elegant and bring a natural look into your 10007. Our processed granite has a subtle shine and feels warm to the touch. The surface is finely textured but not porous, ensuring a high standard of hygiene. Composed of 80% quartz sand and 20% very hard acrylic resin, Franke's hard-wearing granite gives you a lifetime of beauty. 10007s need to be bacteria free. And thanks to the Sanitized treatment, Franke is recognized as a pioneer in the development of Granite compounds for sinks. Sanitized reduces the growth of bacteria on the granite surface by 99%. At the same time, the granite remains resistant to stains and high temperatures up to 536 Degree F.
