Did you know that the human bladder normally holds around 300 to 400 milliliters? This means that if you’re holding an event with food and beverages, plus it’s over several hours, you can bet on guests looking for the bathroom!

But what if your event’s outdoors? Then you’ll need to rely on a porta potty rental.

So when it comes to porta-john rental services, how many should you get for your event? Read on to find out more information!

A General Idea

Every event will have its own special needs, but there are some general rules to follow.

Basically, for every 75 people attending, you’ll need 1 porta potty. For every 4 hours for your event, you’ll need to add one more unit.

So for example, you’ll need 1 porta potty for a 1-hour event with 75 people attending. And you’ll need 3 porta potties for 150 people attending a 5-hour event.

However, there are some factors that can influence how many units you need. Take a look below to see what you need to consider.

How Long Your Event Is

We already briefly covered this above, but on a topical level. The reality is, you need to consider the time it takes for staff to set up and clean up both before and after your event. So when you’re factoring in the event time, don’t forget these crucial time periods!

Female to Male Ratio

If you observe any facilities, you’ll notice that women will take longer to get in and out of the bathroom. In fact, they take twice as long!

So if you have a large female to male ratio, you’ll want to consider renting out a few extra porta-johns to accommodate this. You’ll also want to provide separate units for each gender if you want to make them feel more comfortable and safer.

Food and Drinks

If you’re serving food and drinks, you’ll need to add up to 20% more porta potties, especially if you’re serving alcoholic drinks. Alcohol is a diuretic, which means an increase in urine output.

Keep in mind that what goes in must come out, so if you don’t have enough units, your guests won’t be pleased.

People With Disabilities

Are you going to have people with disabilities at your event? Then you’ll need to rent out handicap porta potties especially for them. If you don’t, then you won’t be compliant with disability laws.

In general, you need to rent out at least 1 handicap-accessible porta-john for every 20 standard ones. If you’re renting out fewer than 20 standard porta potties, then you still need to have at least 1 handicap-accessible one on the premises.
