How many porta potties for an event?
Guest count and event length drive the number. Alcohol increases restroom use, and food service means you'll want handwashing stations.
| Guests | 2 hours | 4 hours | 6 hours | 8 hours |
|---|---|---|---|---|
| 50 | 1 | 1 | 2 | 2 |
| 100 | 1 | 2 | 3 | 4 |
| 250 | 2 | 4 | 6 | 8 |
| 500 | 4 | 8 | 12 | 16 |
| 1,000 | 8 | 16 | 24 | 32 |
| 2,000 | 16 | 32 | 48 | 64 |
Estimates based on each guest using a unit about once every two hours and roughly 125 uses per unit between services. Add about 20% if alcohol is served. Details in how many porta potties do I need.

Frequently asked questions
How many porta potties do I need for 100 guests?
For a 4-hour event with 100 guests, plan on about two units. Add more for longer events or if alcohol is served, and include at least one ADA unit if the event is open to the public.
How far in advance should I book porta potties for an event?
Book as early as you can, especially for summer weekends and wedding season when demand is highest. Call (605) 476-1420 to check availability.
Do I need handwashing stations at my event?
If food or drinks are served, handwashing stations are strongly recommended and may be required by your vendor or venue. A common guideline is one station for every ten units.
Will you service units during a multi-day event?
Yes. For multi-day events we pump, clean and restock units between days so they stay clean for your guests.
