How Many Porta Potties Per Person Do I Need?

When orchestrating a significant event or managing an extensive construction project, the last thing you want is queues forming outside overused porta potties. The key is to secure an ample number of portable toilets to prevent lines and ensure they don’t reach capacity too quickly.

How Many Porta Potties for a Wedding?

For weddings, industry experts recommend one portable restroom per 100 guests for a maximum time limit of four hours. If your celebration extends beyond four hours, it’s advisable to secure a second restroom per 100 attendees. 

For an enhanced experience with minimal wait times, consider the option of one toilet per 50 guests, especially if alcohol will be served. Recognizing the different restroom habits between men and women, adjust your planning accordingly. For a premium solution, consider booking a VIP restroom trailer equipped with air-conditioned units and sinks.

How Many Porta Potties for a Construction Site?

Occupational Safety and Health Administration (OSHA) guidelines mandate at least one toilet for sites employing 20 or fewer workers. For sites with a workforce ranging from 20 to 200 employees, OSHA requires one toilet and one urinal for every 40 workers. If your workforce exceeds 200 individuals, the requirement increases to one toilet and one urinal for every 50 workers. 

While meeting these minimum standards is crucial, exceeding them is a wise investment. According to the American National Standards Institute, having at least one unit for every ten workers is recommended.

The Rule of Thumb

In essence, a minimum of two porta potties per 100 people for every four hours of an event is a prudent starting point. Factor in considerations such as alcohol consumption, extended event durations, and the convenience of attendees. Striving for an optimal restroom experience is a non-negotiable aspect of event planning or construction site management.

Avoid the inconvenience of inadequate restroom facilities by adhering to these guidelines. Need assistance with the calculations?
