500-person corporate picnic: How many units if most are men?

Rent 10 to 12 standard portable toilets, one ADA-compliant unit, and 3 to 5 portable urinals for this event. The male-heavy crowd reduces the need for standard units but increases the value of urinals for throughput. The ADA cluster rule requires at least one accessible unit in the cluster. Event guidelines suggest one standard unit per 50 to 75 people for a four-hour event, but alcohol service and a five-hour duration mean you should use the higher end of that range. Urinals handle more users per hour than standard units, so adding them cuts wait times. Place all units together on level ground with clear truck access for delivery and servicing. Order a mid-event service if the rental company offers it; beer consumption will fill tanks faster. Your rental cost depends on the unit count, rental duration, and service frequency.
