The Shroom family is proud to welcome yet another member to its growing selection of drain accessories-the BathShroom. BathShroom is a unique overflow drain cover that works with virtually any overflow drain type to add extra inches of water to your bath. For fuller and warmer baths, simply place BathShroom around your overflow drain to easily increase water depth, every time. You overflow drain has a low drain point which prevents your bath from filling as high as it's truly capable of.
