How Many Portable Toilets Do I Need?

Resource Overview

Overview

Unit counts come down to three inputs: how many people, how long they are on site, and how heavily the restrooms will be used. Longer hours, food and drink service, and mixed public audiences all push the count higher.

Key Information

Job sites

A common planning figure is one unit per ten workers on a standard work week, adjusted for longer shifts.

Events

Base the count on guest numbers and event length, then add units when alcohol or food service extends the stay.

Accessible units

Include at least one accessible unit at any event open to the public.

Hand washing

Add stations where food is served or workers handle materials.

Practical Guidance

• Round up rather than down; an extra unit costs far less than long lines.
• Split units into two banks when a site has separated activity areas.
• Schedule mid-event servicing for long programs.
• Reconfirm your headcount a week before delivery.
