If you are not sure how many portable restrooms you may need for your event, use this chart to help determine the number you may need
based on the number of people at your event and how long the event will last.
How to use this chart:
- Determine how many hours the event wilI last. If the event is multiple days, use the longest day.
- Determine how many people will attend. If the event lasts multiple days, determine the peak day.
- Use the chart to calculate the number of portable restrooms needed for adequate sanitation conditions.
Special considerations:
- If alcohol is being served, add 15-20% more restrooms.
- Add one extra-large restroom per 20 portable restrooms, or a minimum of one for events open to the public.
- Adequate hand washing should also be provided with restrooms in all food service areas.
