ABSTRACT:
Bathing fixtures, such as bathtubs and shower receptors and devices such as diving boards and surfboards, are provided with a contoured surface, at least within an area on which a person normally sits or stands, to provide within such area a great number of alternate, raised and depressed surface portions bounded by sharp edges which break down slip-promoting liquid film. The depressions are substantially flat bottomed, very shallow and operate to support a portion of the bather's weight, the portion varying between a lesser weight percentage during the period a bather begins to transfer weight onto the contoured surface, this being the period during which the danger of slipping is greatest, and a greater weight percentage during the subsequent period during which the contoured surface supports the bather's full weight.
