What Is the Correct Ratio of Portable Toilets to People for an Event?

June 17, 2021

Hosting an event requires a lot of planning—and some might argue that planning for portable toilets in El Centro, CA is the most important task of all. After all, no one wants to run to use the restroom, only to find that there’s a line wrapped around the block. If your guests have to wait absurd amounts of time to use the bathroom, that’s likely to be the only thing they remember about the event. On the other hand, you don’t want to rent too many porta potties, either. Here’s how to figure out how many portable toilets you’ll need for an event.

Ask yourself these questions

When planning your next event, knowing the answers to these questions will help you and your rental company determine the right number of toilets:

  • What kind of event is it, and how long will people be there? The need for a restroom can vary wildly depending on the type of event you’re hosting. Events where people are expected to spend all day on the premises will necessitate more restrooms than a local church carnival, for example. Similarly, events that cater primarily to women may need to provide extra facilities. To get an initial ballpark figure, estimate one toilet per 50 attendees. However, expect other event factors to increase that number—especially if the event is planned to last longer than a few hours.
  • How long does the event run? Over how many days will the event take place? If you’re hosting a multi-day event, it’s smart to rent a few “extra” restrooms. Accidents can happen that could render a portable restroom unusable, at least until the rental company can come to service the unit.
  • Will food, beverages and alcohol be served? Whenever food and beverages (especially alcohol) are involved, the recommended portable restroom number goes up. People need to use the restroom and wash their hands after they eat, and if you’re serving alcohol, that need is particularly magnified. You’ll need about 10 to 20 percent more porta potties at an event with concessions.
  • Are there permanent restrooms available? Not every event space offers permanent restrooms—if they do, you’ll need fewer portable ones. Make sure you know how many public restrooms or stalls are available, then subtract that number from your ballpark estimate.

The best way to figure out how many portable toilets you’re likely to need is to talk to a rental company. This might be your first event where portable restrooms are required, but it won’t be theirs. Porta potty rental companies are experts at estimating how many toilets you’ll need based on the factors above. When you call, have your projected attendance figures handy, as well as any other pertinent event information.
