Usage Chart

Let us make planning your event easy. All you have to know is how many people will be attending your event and how many hours the event is scheduled for.

How to use these charts

  • Determine how many hours the event will last. If it is multiple days, use the longest day
  • Determine how many people will attend. If there are multiple days, determine the peak day
  • Use the chart to calculate the number of portable restrooms needed for adequate sanitation conditions
  • Note: if alcohol is being served, add 15-20% more restrooms
