How Many Units

The number of portable toilets you need is driven by how many people, for how many hours, whether alcohol or food is served, and whether the units get serviced during the event. Industry planning charts start from roughly one unit per 50 to 75 people for a four-hour event and add units for alcohol, longer hours and women-heavy crowds.
