Flat back Urinals

First patented in 1866 by Andrew Rankin, the urinal was originally designed as a fixed, stand-up toilet for male urination. It had several advantages that made it an instant success. First, it improved public sanitary conditions by eliminating the splashing contaminants that accompany male urination. Second, it reduced the amount of time and number of toilets needed in public facilities. And third, urinals use less water and are more efficient than conventional toilets

Todays urinals, as with most inventions, have evolved improvements to keep pace with modern changes. In addition to traditional urinals, waterless urinals, as well as portable urinals designed for both sexes have become commonplace. Below are listed the differences.
