Our integrated anti-microbial sanitized technology helps to reduces odors and ensures safe protection against bacteria and mildew in your sink. The integrated ledge enhances the functionality of the sink by creating an elevated workspace, allowing you to work directly over the sink. Clean lines, tight corners add a contemporary edge to this line of sinks, while the drain cover provides a flat bottom surface so glassware can stand up in the bowl of the sink.
