Puking is bad, but I look at slippery surfaces, soapy water, lack of anything to hold onto, combined with only hard stuff to fall on as a greater risk than many of the things about which people fantasize (mold, CO from the kitchen stove, lightning...) Children and the elderly are especially prone to falls. Often, the first sign a person has that they are getting old is they begin to fall somewhat regularly. Modern tubs and showers have non-skid floors for good reason. When I see a tub like this, I feel obliged to warn of the risk to children, in-laws, grandparents and the handicapped more than I do possible leaks. Of course I report that too.
