How many porta potties do I need for my event?

The general rule is 1 porta potty per 50 guests for events up to 4 hours. Here's a more detailed breakdown:

• Up to 4 hours: 1 unit per 50-100 guests
• 4-6 hours: 1 unit per 40-75 guests
• 6-8+ hours: 1 unit per 35-50 guests

Increase your count if:

• Alcohol is being served (add 20-30% more units)
• The crowd is mostly women (add 20% more units)
• Food is being served (increases restroom usage)

For construction sites, OSHA requires 1 toilet per 20 workers.
