How many porta potties does a graduation party need?
A graduation party needs 1 porta potty per 50 guests for up to 4 hours. Most open-house parties run 4 to 6 hours with guests coming and going, so a 100-guest party usually needs 2 units, or 3 if the party runs past 4 hours. Add 1 handwashing station because food is served.
| Guests | 4-hour open house | 6-hour party |
|---|---|---|
| 50 | 1 | 2 |
| 100 | 2 | 3 |
| 150 | 3 | 5 |
| 200 | 4 | 6 |
Which unit is best for a graduation party?
A standard porta potty plus a handwashing station is the best value for most graduation parties. A flushing unit with a built-in sink is better when grandparents and dressed-up guests attend, and a wheelchair-accessible unit is the right choice when any guest uses a wheelchair or walker.
Compare units on the standard unit page and the flushing unit page.

When should you book for graduation season?
Book porta potties for a Metro Detroit graduation party 2 to 3 weeks ahead. The busiest weekends are early to mid-June, when many high schools hold commencement and open houses overlap. Units for Saturday parties are delivered Friday and picked up Monday at no extra charge.
Where should the porta potty go at a backyard party?
The porta potty should go on level ground near the driveway, 30 to 60 feet from the food tent, with the door facing away from the main seating. Keep the truck path clear the day before. A standard unit needs a gate at least 48 inches wide to reach a backyard.
