Portable Toilet Rental: How Many Do I Need?

As someone in need of portable toilet rental in the Arizona Valley, one of your top questions is likely “How many porta-potties do I need?” We know this because it’s a question that’s not only asked by people in our service area throughout the Valley. It’s something people across the country want to know.

We don’t blame you. You want to be sure that you’re fully prepared, whether you have an upcoming festival and need portable restrooms in Mesa or will be managing a job site and require portable toilets in Scottsdale. However, you don’t want to overestimate and pay for more porta-potties than you actually need.

That’s why we developed the chart below. We wanted to provide a useful reference that can be quickly used to make portable toilet rental decisions. By being an informed renter, you’ll make sure you don’t underestimate and create a situation where there are long lines and overused, smelly portable restrooms or the converse where you overestimate and unnecessarily burn your hard-earned money.

Using the chart is easy. Choose the rows for the length of the event and the estimated number of attendees. Where those rows intersect, that’s how many portable restrooms are recommended. If it’s a multi-day event, calculate based on the longest day of the event as well as the day with the highest estimated attendees.

If food and/or alcohol are being served at the event, increase the restroom count by 15-20%. You should also add 1 handicap-accessible portable restroom and 1 portable sink for every 4 standard units rented.

Need to rent porta-potties for a construction site? A general rule of thumb is to rent 1 portable restroom for every 10 workers during a 40-hour workweek. If operating two shifts, double your porta-potty count. (Example: 1 shift with 40 workers = 4 porta-potties; 2 shifts with 40 workers = 8 porta-potties)

If operating three shifts, triple your porta-potty count. (Example: 1 shift with 60 workers = 6 porta-potties; 3 shifts with 60 workers = 18 porta-potties). The exemption to this rule is if you operate three shifts with 80 or more workers. In that case, 32 porta-potties are recommended.
