Strikingly beautiful the FRESCA vessel sink is a fixture of beauty. From the exclusive hand painted vessel collection of Novatto, it adds a touch of style to any bath. Novatto?s tempered glass vessels will enhance and harmonize the look of any bath by unifying the color and textural design. Constructed of high tempered glass, this rectangular vessel sink has a unique hand-painted design of blue and black. At 21.75-inches wide there's plenty of room to wash those hands. Novatto uses advanced technology, including computerized glass processing, to produce glass basins with unmatched structural integrity and longevity. The sink has standard 1.75-inch drain opening. Suggested Novatto pop-up drains: PUD-ORB (oil rubbed bronze), PUD-BN (brushed nickel), PUD-MB (matte black) and PUD-CH (chrome). No mounting ring is needed with this sink since it has a flat bottom. In-house testing has found these glass vessels to be very durable and forgiving. For best cleaning results, apply Glacier Ice which will help seal the glass for easier cleaning. A soft cloth with mild soap and water or a non-abrasive glass cleaner is recommended for everyday cleaning.
