How Many Portable Toilets Do You Need for Your Event?, Madrid, Iowa

Whether you’re planning an intimate wedding reception or a large music festival, your guests and attendees will need access to clean, serviceable bathrooms. Portable toilets are ideal for crowds of 50 up to several hundred thousand, but you might wonder exactly how to calculate the number of rentals you’ll need. Refer to the following guide from professional septic services.

4 Factors That Determine How Many Portable Toilets to Rent

1. Event Length Versus Crowd Size

portable toiletsThe Portable Sanitation Association International recommends that you reserve approximately two portable toilets for every 500 people per each hour of your event. For instance, if you’re expecting about 1,000 guests for a two-hour function, rent six to eight port-a-potties.

2. Adult Beverages

If you plan to serve beer, wine, and cocktails at your event, attendees will likely need to use the restroom more frequently. Calculate the number of portable restrooms you need for the size and length of your event, then include an additional 15 to 20% more port-a-potties.

3. VIP Guests

For performers, guests of honor, and volunteers at your event, it’s a good idea to rent restroom trailers complete with flushing toilets, portable sinks, mirrors, ventilation, and air conditioning. Reserve one restroom trailer for every 10 to 15 VIP attendees.

4. Handicap Accessibility

Handicap accessible portable toilets are necessary for any event. For every 20 port-a-potties you reserve, include one handicap accessible facility. They include ramps, more square footage, no-slip flooring, and grab bars for optimized safety.
