Graduation Party Porta Potty Guide for St. Charles County Families

Graduation weekends in late May are the busiest party weekends of the year in St. Charles County. Open houses run long and guests come in waves, so a little planning keeps the line short and the house clean.

Graduation Party Porta Potty Guide for St. Charles County Families

How many porta potties does a graduation party need?

A graduation open house with 100 guests over 4 hours needs 2 standard porta potties. With 150 guests over 5 hours, plan 4. Open houses spread guests over time, so the guest-hours method works well. Add a hand-wash station when food is served, which is almost always.

Use the porta potty calculator for your exact guest list.

When should I book a porta potty for graduation?

Book a graduation porta potty 3 to 4 weeks ahead. The Fort Zumwalt, Francis Howell and St. Charles district ceremonies cluster in mid to late May, and many families party the same weekends. Saturday drops sell out first, so a Friday drop for a Saturday party is the safest plan.

Where should the porta potty go at an open house?

Put the porta potty at the side of the house or the end of the driveway, about 20 to 50 feet from the food tent. Guests should reach it without walking through the house. Add a lantern or porch light if the party runs past dusk.
