How Many Portable Toilets Do You Need?

Whether you are planning a wedding, a festival, or managing a busy construction site, one question comes up every time: how many portable toilets do you actually need? Too few units lead to long lines and unhappy guests or workers. Too many is an unnecessary expense. At Gill's Southern Sanitation Service, we help event planners and construction managers across Southwest Mississippi get this number right the first time.

Start With Headcount and Duration

The most important factors are how many people will be on site and for how long. A general rule of thumb for events is one portable toilet for every 50 guests during the first four hours, with an additional unit for every 50 guests for each extra hour of the event.

For construction sites, OSHA guidelines generally recommend one toilet for every 10 workers on an eight hour shift. If your crew works longer shifts or multiple shifts, you will need to adjust accordingly.

Consider the Type of Event or Site

• Weddings and formal events: Guests expect comfort and cleanliness, so consider upgraded or deluxe restroom trailers in addition to standard units.
• Festivals and large public gatherings: Higher foot traffic means more frequent servicing and a higher unit count to prevent long wait times.
• Construction sites: Durability and placement near the work area matter most. Handicap accessible units may also be required depending on your crew and local regulations.

Don't Forget Handwashing Stations

Handwashing stations are essential for food service events and construction sites alike. We recommend pairing one handwashing station for every two to three portable toilets to keep guests and workers comfortable and hygienic.

Plan for Servicing and Holding Tanks

For multi-day events or extended construction projects, servicing frequency matters. Our team can schedule regular pump-outs and cleanings so your units stay fresh throughout your project. For larger sites, a holding tank may be a smart addition to reduce the frequency of service visits.
