"Microban® antimicrobial protection is built-in to products during manufacturing to provide continuous antimicrobial product protection. And because Microban protection is built-in, it won’t wash off or wear away providing continuous antimicrobial protection for the life of the product.

The bathroom can be a fertile breeding ground for microbes like bacteria, mold and mildew. In fact, if left unchecked bacteria levels can double in number every 20 minutes.

It’s a constant battle especially in high humidity and moisture areas like the bathroom. Microban protection fights the growth of microbes that can cause stains and odors on bathroom surfaces, so they’re easier to clean and stay cleaner and fresher between cleanings." - Microban
