Designed to work with glass, stone, ceramic, or any sink with a drain opening. Complete your vessel sink with this pop-up drain with overflow. This pop-up drain will not fit most copper bath sinks or drain openings. The good thing about pop-up emitters is that if there's no steady flow of water, the lid stays shut. That means no debris can make its way into the pipe.
