The Mainstays Shower Liner keeps water from spilling out onto the bathroom floor. You can use it alone or as a backing for a cloth curtain. This PEVA shower liner wipes clean easily so you spend less time on care. The clear design allows you to see your exterior layer (sold separately). This liner fits on standard shower hooks for easy installation (hooks not included). A set of magnets keep the bottom attached to the tub to minimize billowing.
