Complete your vessel sink with this 1.75" Pop-Up Bathroom Sink Drain and mounting ring from Novatto. It is constructed of solid brass and plated with a lifelong finish for trouble-free use. Designed to work with glass, stone, ceramic, or any sink with a 1.75-inch drain opening, this pop-up drain will not work with most copper bath sinks or drain openings less than 1.75 inches. The drain assembly includes two rubber seals and a brass fastener for easy installation. The drain is 9 inches in total length. This high-quality mounting ring is compatible with any vessel sink with a rounded bottom. Measuring 3 inches in diameter by 3/8 inches high, the ring is to be installed between the vessel sink's bottom and the top of the counter. Constructed of solid brass for strength and durability, it is highly recommended for added stability and easier countertop cleaning under the vessel. Superior packaging and double boxing ensure damage-free delivery.
