Combine quality and design with a unique clear glass vessel from Novatto. As an industry leader, Novatto uses advanced technology to produce beautiful glass vessel sinks with unmatched structural integrity and longevity. Constructed of thick 1/2-inch high tempered clear glass, the Piazza is a modern square shape. Tempered glass cannot be compared to everyday synthetic porcelain and ceramics. Internal testing has found these vessels to be very durable and forgiving. Items such as toothbrushes or small jewelry should not scratch the surface. Made with the highest standards of quality and creative design, Novatto sinks add art and function to any decor at an affordable price. Piazza has a standard 1.75-inch drain opening. The set includes a chrome pop-up drain and matching mounting ring.
