While trying to decide on flooring for my bathrooms I learned that Marmoleum is often used in dormitory rooms, military barracks and prisons. Minor turn off. Then I read Marmoleum possesses a self-sanitizing quality. Major turn on. "Independent testing has shown that Marmoleum has a sterile zone around the material that inhibits the growth of organisms such as Staphylococcus Aureas and Clostridium Difficile." Resistant to bacteria and a certified sustainable flooring.
