The Kenney microCLEAN Antimicrobial Protection Medium Weight PEVA Shower Curtain Liner inhibits the growth of stain and odor-causing mold and mildew and provides enhanced product protection. The Kenney microCLEAN PEVA Shower Curtain Liner has been specially treated with antimicrobial additives to reduce bacteria, fungi and algae growth on the product. The Shower 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 (178 cm x 183 cm) to fit most showers and bath tubs.
