How Many Portable Toilets Do I Need?

Overview

Choosing the right number of portable toilets starts with the people using the site, how long they will be there, and what they will be doing. A construction crew, a wedding reception, and a short community event can have very different restroom needs even when the headcount is similar. Use the planning factors below as a starting point, then discuss the actual site and schedule when requesting a rental.

Key Information

Job sites

Consider the size of the crew, project duration, work schedule, and whether permanent restrooms are available nearby. Long projects also need a servicing plan.

Events

Consider attendance, event length, the type of event, and how guests will move around the property. Setup and cleanup periods can also affect the rental window.

Accessible units

If the site needs an accessible restroom, include an ADA unit in the overall plan rather than treating it as a last-minute addition.

Hand washing

Think about whether a dedicated hand washing station should be included, especially when the site has food service, high traffic, or restroom groups spread across a large area.

Practical Guidance

Use this checklist as a planning aid. The exact rental plan should be based on the property, schedule, expected use, and access available at the site.

• Start with the expected number of users and rental duration.
• Separate general restroom needs from accessibility needs.
• Consider peak attendance or busiest work periods.
• Look at the property layout and where users will actually be.
• Plan servicing based on use instead of assuming every site needs the same schedule.
