In every shower diverter stem lies an even smaller plumbing part: the diverter washer. Diverter washers provide a positive seal at this critical junction in your bathtub/shower system, and are essential for preventing leaks. So, if your shower/tub is leaking, you might need to replace your diverter washer. Browse among our wide selection of diverter washers below, and stop that leak once and for all!
