How Many Portable Toilets Do You Need? Westboro Sanitary Experts Explain

11/21/2017

Whether you're planning a big event or you're starting a new onsite project, portable toilets are an excellent way to meet the sanitation needs of guests, clients, and employees. Deciding to rent port-a-potties is easy, but determining the amount needed to accommodate the crowd can be challenging. The sanitation service professionals at Silver Creek Services in Taylor, Price and surrounding counties in Wisconsin, have the science of calculating portable toilet accommodations down to a T, and they're here to share their expertise.

How to Determine the Number of Portable Toilets You Need

The two most important factors when determining the number of rentals are the amount of users and length of the time. Events and job sites should be factored differently because their needs aren't the same.

When it comes to events like weddings, family reunions, and outdoor concerts, it's important to start with the highest estimated number of expected attendees. In such situations, a quick rule of thumb is to use one toilet rental for every 50 people per four hours.

For instance, if you're planning an eight-hour event with 100 guests, you need four portable toilets. If alcohol is served, take your original estimate of attendees and increase it by a quarter, then refactor the number of port-a-potties that you will need.

The port-a-potty rental rule is slightly different for job sites because there's less fluctuation in the usage. Rent at least one portable toilet for every 10 employees per eight-hour shift. If you run multiple shifts during the day, acquire at least one restroom per shift. For instance, if you have seven employees per shift, and you operate around the clock — three shifts — you will need three port-a-potties.

My husband and I are planning a big family reunion this summer, and we're going to have it in a park about thirty minutes from our home. We were thinking we should probably rent some portable toilets so that people don't have to travel back and forth to use the restroom. Thanks for pointing out that if you're planning an eight hour event with 100 guests, you need four portable toilets. We'll probably have about that many people, so we'll have to contact a professional and have them come out and get those toilets set up for our big event.

That's interesting that you should increase the amount of portable toilets if you serve alcohol at an event. My daughter is getting married next spring and she wants her reception outside. We'll have to look into getting portable toilets and remember to increase the number since there will be alcohol at the event.

Thanks for the tip that 4 portable toilets would be enough for an 8-hour outdoor event. My boyfriend and I are planning to have an outdoor wedding someday and the reception would most likely be outdoors as well. Perhaps around 4 portable toilets would indeed be enough for that kind of even since our guest list didn't even reach the hundreds anyway.
