The Mainstays 3-Gauge PEVA Shower Liner is lightweight, odorless and chloride free. It has a weighted magnetic bottom to help keep the liner close to your tub walls so water stays inside your shower and drafts outside. A reinforced header makes it easy to securely attach the liner to any shower curtain hooks or rings. The liner can be used alone or with a decorative fabric shower curtain. Wipe with a damp cloth for easy care. The liner measures 70 in. by 72 in. to fit in standard tub and shower areas.
