From the exclusive hand-painted vessel collection of Novatto, Tappezzeria is a blend of elegance and contemporary drama. Constructed of high tempered glass, this round sink has a unique hand-painted design of brown, tan and black. Tempered glass cannot be compared to everyday synthetic porcelain and ceramics. Novatto uses advanced technology, including computerized glass processing, to produce glass basins with unmatched structural integrity and longevity. In-house testing has found these glass vessels to be very durable and forgiving. Standard 1.75-inch drain opening. Suggested Novatto pop-up drains: PUD-ORB (oil rubbed bronze), PUD-BN (brushed nickel), and PUD-CH (chrome). Suggested matching Novatto mounting rings: MR-001ORB (oil rubbed bronze), MR-001BN (brushed nickel), and MR-001CH (chrome). For best cleaning results, a soft cloth with mild soap and water or a non-abrasive glass cleaner is recommended.
