The Mainstays Heavyweight PEVA Shower Curtain Liner is waterproof, odor- and chloride-free, and has a reinforced mesh header at its top, with rustproof metal grommets to prevent tearing. The heavy duty liner is designed to hang straight down so it's close to your tub wall to keep water inside your shower and drafts on the outside. Wipe with a damp cloth for an easy clean. The liner measures 70 in. by 72 in. to fit most standard size shower and tub areas.
