How Many Porta Potties Per Person Do You Need


Planning Your Event: How Many Porta Potties Per Person Do You Need?


When planning an event, one of the crucial logistical aspects to consider is the availability of restroom facilities. You might be asking, “How many porta potties do I need per person?” This question is more important than it seems, as having too few can lead to discomfort and long lines, while too many can be an unnecessary expense.

Let’s break down the numbers to ensure your event’s success.

 1: Understanding the Basics

Porta potties, or portable toilets, are essential for outdoor events, construction sites, and wherever permanent restrooms aren’t available. The right number depends on several factors, including the size of the crowd, event duration, and whether food and drinks are served.

 2: Standard Recommendations

  • General Guidelines: A common rule of thumb is to have at least one porta-potty for every 50 people for a four-hour event.
  • Larger Gatherings: For events with more than 50 people or lasting longer than four hours, you’ll need more porta potties.
  • Food and Drink: Events with food and beverages typically require more porta potties as they increase restroom usage.

 3: Calculating Your Needs

  • Event Duration: As a basic guide, add one porta potty for every additional 50 people per four hours.
  • Type of Event: Consider the nature of the event. For example, concerts or festivals might need more porta potties compared to a corporate outdoor event.

 4: Special Considerations

  • Children’s Events: Events with children might require more porta potties, as kids often need to use the restroom more frequently.
  • ADA Compliance: Ensure you have accessible porta potties for attendees with disabilities; generally, at least 5% of the total number of toilets should be wheelchair accessible.

 5: Tips for Placement and Maintenance

  • Strategic Placement: Spread out portable potties to avoid congestion.
  • Maintenance: For multi-day events, regular cleaning and maintenance are crucial. Consider daily servicing for events lasting longer than a day.

 Standard Recommendations for Porta Potties Based on Event Size and Duration

Event Size (Number of People) Event Duration Minimum Number of Porta Potties Required
Up to 50 Up to 4 hours 1 porta potty
51 – 100 Up to 4 hours 2 porta potties
101 – 150 Up to 4 hours 3 porta potties
151 – 200 Up to 4 hours 4 porta potties
Every Additional 50 People Every 4 hours Add 1 additional porta potty

Additional Considerations:

  • For events with food and beverages, increase the number of porta potties by approximately 20-30%.
  • For events lasting longer than 4 hours, consider adding more porta-potties to accommodate increased usage.



Calculating the number of porta potties per person is key to the comfort and satisfaction of your attendees. Use these guidelines as a starting point, but always consider the specific needs of your event. Remember, it’s better to err on the side of having too many than too few!
