Showers and Tubs are incredibly slippery on their own.. adding a soap spill or a physical limitation (being a child or elderly) can be a dangerous combination.
Here are a few interesting facts that I found..
~According to a study by the "Center for Injury Research" & Policy of The Research Institute at Nationwide Children’s Hospital, over 43,000 children 18 years & younger in the US are treated in hospital emergency rooms each year for injuries occurring in a bathtub or shower. (1990-2007)
~According to the National Safety Council, a person dies everyday from use of a bathtub or shower in the US.
~According to some studies ONE-THIRD of the elderly injure themselves in the shower/tub.
