Public restrooms are no one's favorite place, but in today's age they're not nearly as public as they used to be. The beginning of the history of public bathrooms is often remembered by no privacy and hole-in-the-ground toilets. Some of the latrines were actually on major pathways as well.
So, how have public bathrooms changed over the years? Gradually - and thankfully - stall walls were eventually put up and individual hand-washing stations were included. Aside from the partitions, though, it's surprising how similar public restrooms really are today to Roman times.
