Planning an outdoor event in Minnesota? Whether you’re organizing a wedding, festival, graduation party, company event, or community gathering, one important question is: how many portable toilets do I need?
Whether you call them portable toilets, porta potties, or Biffs, having the right number can help prevent long lines and keep guests comfortable. The number you’ll need depends on your guest count, event length, beverages being served, and other factors.
How Many Portable Toilets Do You Need Per Guest?
A helpful starting point for shorter events is approximately one portable toilet for every 50 guests.
| Number of Guests | Suggested Portable Toilets |
| 100 | 2 |
| 250 | 5 |
| 500 | 10 |
| 1,000 | 20 |
These are general planning estimates, not exact requirements. The length and type of your Minnesota event can change how many portable toilets you’ll need.
Serving Beverages? Plan for More Portable Toilets
If your Minnesota event will be serving plenty of beverages, you may want to plan for increased restroom use. This is especially important when alcohol is being served, as guests may need to use the restroom more frequently.
Serving Alcohol? Consider Adding More Portable Toilets
100 guests → 3 portable toilets
250 guests → 6 portable toilets
500 guests → 11 to 12 portable toilets
1,000 guests → 22 to 24 portable toilets
Weddings, concerts, festivals, company parties, and other events where guests are drinking throughout the day or evening may benefit from additional restroom capacity to help keep lines moving.
These are general planning guidelines. Event length, beverage consumption, venue layout, and other factors can affect how many portable toilets your Minnesota event needs.
Consider the Length of Your Minnesota Event
The longer your event lasts, the more restroom use you can expect. An all day Minnesota festival will typically need more restroom capacity than a short outdoor gathering with the same number of guests.
Longer or multiday events may also require additional units or scheduled servicing.
Don’t Forget ADA Restrooms and Handwashing Stations
Your event setup may also benefit from ADA accessible portable restrooms and portable handwashing stations.
Accessible units help accommodate guests who need additional space and accessibility features, while handwashing stations are especially useful for Minnesota events with food vendors, catering, or large crowds.
Important: Water from portable handwashing stations is intended for handwashing only and should never be used for drinking.
