The kenney medium weight peva shower curtain liner is made of environmentally friendly peva, making it pvc-free and odorless. The liner has 12 rust-resistant metal grommet hang holes to prevent tearing from shower hooks and rings. The weighted hem on the waterproof liner keeps the liner in place, so water stays in your bathtub and off of the floor. Standard sized, it measures 70 inches wide by 72 inches tall (180 cm x 183 cm) to fit most showers and bath tubs.
