Since the default assumption is that 100% of male occupants will use a restroom with a urinal, how do you calculate the usage when there is a family toilet (without a urinal) next to the large gang restroom? My guess is that a certain % of the male (and female) population is assumed to use the family toilet in lieu of the gang restroom. However, what would that percentage be? Any ideas of where I could derive an idea of that percentage?
Although the family toilet is ADA accessible, there is also an ADA toilet stall in each of the gang restrooms, so I can't use the ADA calculation to determine the % of people requiring the usage of the family toilet. Any guidance/ideas would be appreciated! Thanks.
