The people who did the research do think it is a big deal, and it might be exactly the reason why you don’t use a urinal (although that could also have to do with your body parts, I don’t know you).
[…] the researchers wrote in the study. “The use of urinals often results in significant splatter (splashback) as urine splashes upon impact with the urinal generating droplets which travel back onto the floor and user.”
This splashback is a breeding ground for bacteria, resulting in bad smells in public restrooms and the potential for the spread of diseases.
“The surfaces of urinals have significantly higher concentrations of bacteria than traditional toilets, with surrounding floors having the highest level,” the researchers added.
This high level of spillage of urine requires frequent cleaning, which uses a large volume of water, is unpleasant work for custodial staff and is very expensive.
