According to a study, the average time it takes to use the bathroom (#1) is 21 seconds.
Nurse practitioner Janis Miller, PhD, told Well and Good , quote:
“If you find that you almost always pee for significantly less or more than 20 seconds, consider examining your bladder habits: Are you drinking too much water or not enough? Are you giving yourself enough bathroom breaks during the day? Or are you using the bathroom more than you need to because it’s the only private place in your house? Your answers can help you to tweak your bladder habits.”
