How many porta potties does a graduation party need?
A graduation party needs 1 standard porta potty per 50 guests for a 4-hour party. Most open-house parties run longer, so multiply guests by hours and divide by 200: a 120-guest, 6-hour open house needs 4 units. Add 1 unit for every 4 if alcohol is served.
| Guests | 4-hour party | 6-hour open house |
|---|---|---|
| 50 | 1 | 2 |
| 100 | 2 | 3 |
| 150 | 3 | 5 |
| 200 | 4 | 6 |

When should you book graduation party porta potties?
Book graduation party porta potties 2 to 3 weeks before the party for late May and June weekends in the Harrisburg area. Standard units are often available on shorter notice, but sink units, wheelchair-accessible units and flushing units go first on popular Saturdays.
Do you need a sink or a hand-wash station?
A graduation party with food should have water for hand washing. For 1 or 2 toilets, a porta potty with a sink inside is the cheaper choice. For 3 or more toilets, add a free-standing hand-wash station near the food line.
Graduation party porta potty checklist
Use this 8-point checklist one week before the party. Each item prevents a common day-of problem, from a truck that cannot reach your backyard to a unit placed beside the buffet table.
- Count guests and hours. Use the 200 guest-hour rule.
- Pick unit types. Standard, plus a sink or accessible unit if needed.
- Choose the spot. Flat, 50 feet from food, door away from the party.
- Check the gate. A standard unit needs a 48-inch opening.
- Tell neighbors. Placement near a shared fence is easier with a heads-up.
- Confirm delivery day. Usually the day before; Saturday parties get Friday.
- Add lighting. A path light for evening guests.
- Leave it for pickup. Next business day; no cleaning needed.
