And now Lucite acrylic is available with built-in Microban® antimicrobial product protection. Microban protection inhibits the growth of bacteria that can cause stains and odors on the tub surface. The continuous antimicrobial protection makes tub surfaces easier to clean and keeps them cleaner between cleanings. And because it’s built-in during manufacturing, it won’t wash off or wear for an added level of cleanliness that will last the life of the tub.
