Complete your vessel sink with this pop-up drain with overflow from Wisine. It is constructed of solid brass and plated with a lifelong brushed nickel finish for trouble-free use. Compatible with a glass, stone, ceramic or any sink with a 1.75-inch drain opening, this pop-up drain will not fit most copper bath sinks or drain openings less than 1.75 inches. Also this drain will not work with a sink which does not have a sink overflow. The drain assembly includes two rubber seals and a brass fastener for easy installation.
