In the most recent statistics The Center for Disease control and prevention (CDC) estimates over 205,000 fatalities occurred from falling in the US from 1999-2009. Obviously the combination of water and the slick hard surface of the bathtub floors make the bathroom the most at risk place for injuries/deaths from slipping. Please make sure to stay safe and treat your bathtubs to make them less slippery. Please ensure you determine the type of bathtub you have for the correct product. If it has a metal sheel its likely porcelain. If it's flexible is acrylic or fiberglass.
