It takes me approx 1 minute and 45 seconds to go from my desk to the bathroom (use it, wash) and back.

I do this at a minimum of 4 times a day (sometimes more. I drink a lot of water/coffee/coke).

There are approx 260 working days in a year.

I am paid somewhere in the neighborhood of $21 an hour, although whether that is before or after tax I don’t remember, nor does it really matter I guess.

So:

7 minutes a day in the bathroom + 260 work days a year = 1,820 minutes a year in the bathroom.

1,820 minutes = 30.3 hours

30.3 hours a year in the bathroom on company time = $636.30 a year to go to the bathroom.

Obviously this number is grossly underestimated since I can sometimes spend around 30 minutes in the bathroom when I have a “long” visit, plus several short visits. Some days I take 1 short visit every 30 minutes (when I drink around 50oz of water, plus 4 cups of coffee, which I have actually done, although I’m sure this only happens about once a month. I chose 4 short visits a day because this is the absolute minimum).
