How many porta potties for a party?

The 4-step rule planners use in Santa Clarita.

Step 1: 1 per 50 guests

100 guests for 4 hours = 2 porta potties. Always round up.

Step 2: Alcohol adds 1 per 4

Serving drinks? 2 toilets become 3. Lines move faster.

Step 3: Over 6 hours adds 1 per 4

Long receptions use units more. Plan for the peak hour.

Step 4: Food? Add a sink

1 hand-washing station for every 3 toilets.
