Blanco"s premium quality (304 series, 18 gauge, 18/10 chrome-nickel content) stainless steel is non-porous, hygienic, rust free and durable. Supported by our no-hassle, limited lifetime warranty. Features Blanco"s satin polish finish, which features a long-lasting, easy-to-clean luster, which resists water stains and calcium deposits. Tight radius corners in Blanco sinks mean more bowl space and a flat sink bottom. Rear drain placement creates a more useable sink bottom and maximizes functional cabinet space underneath your sink. Blanco"s insulation pads ensure water temperature retention and maximum sound deadening, including the growl of your garbage disposal.
