Susie is a wedding planner. She is planning a wedding for 200 guests at a vineyard. How many porta johns does she need to rent?

This type of real-life word problem can be tricky when you don’t know the ratio of guests to porta johns. And that’s not the only consideration. You have to think about space, budget, event style, and more.

This article will explain the toilet-to-person ratio for your event, how that ratio can change, and how to get a great porta john rental.

How Many Porta Potties Do I Need?

Here is the general rule – you will need one porta john rental per 75 guests. So, if your event is 150 people, two porta potties should be sufficient but if you plan an event with 500 people you may need six or seven porta johns. If your site has fewer than 75 people, one porta potty is usually acceptable.

But before you rent a porta potty, read the advice below. There are a few other criteria to help guide your toilet rental decisions.

Are There Other Bathroom Options?

Does the venue have stand-alone bathrooms too? If so, that can impact your toilet-to-person ratio. If there is a typical men’s and women’s restroom, you can count each stall as one bathroom rental in your new calculation.

If there is only one, single-person restroom you can count that as one bathroom rental. 

Are You Serving Alcohol?

Part of event planning is deciding on food and drinks. And if your event includes alcohol, that could also affect the number of bathroom rentals you need.

Alcohol is a diuretic, meaning it increases the frequency of bathroom use. So, if you are serving alcohol, consider bringing your toilet-to-person ratio to about one porta john per 50 to 60 people. This will help prevent long lines of people waiting outside the bathrooms. 

How Long Is the Event?

The longer the event, the more porta johns you need. The 75 person-per-porta potty rule applies for events up to four hours. For events that last longer than four hours, you may need an additional one to two porta potties.

How Much Space Do You Have?

The number of porta johns and the type of porta johns will depend on how much space you have too. For example, luxury portable bathrooms take up more space than traditional porta johns. And festival sites usually have more room for bathrooms than a backyard wedding.

So, as you are deciding on the number of bathroom rentals you need, consider your space or better yet, take measurements!
