Selecting the right number of portable toilets is crucial for the comfort and compliance of your guests or crew. Use the charts below to quickly estimate how many units your event or job site requires.
Construction Site Capacity
OSHA (Occupational Safety and Health Administration) requires specific minimum ratios for construction sites to ensure adequate sanitation is provided. These requirements are based on a standard 40-hour work week.
OSHA Recommended Units per Worker (40-Hour Week)
| Number of Workers | Minimum Number of Toilets Required |
|---|---|
| 1–10 | 1 |
| 11–20 | 2 |
| 21–30 | 3 |
| 31–40 | 4 |
| 41–50 | 5 |
| 51–60 | 6 |
**Note:** For every **10 additional workers**, add **1 additional toilet**. If the worksite has more than 20 workers, one unit must be an **ADA-compliant unit**.
Event & Special Occasion Capacity
Event requirements depend on the **duration** and the **expected number of guests**. The ratios increase for longer events or if alcohol is served (which typically doubles usage).
Recommended Units for Events (Standard Use)
| Number of Guests | 2-4 Hour Event (No Alcohol) | 4-8 Hour Event (No Alcohol) | Full Day Event (With Alcohol) |
|---|---|---|---|
| 50 | 1 | 2 | 3 |
| 100 | 2 | 3 | 5 |
| 250 | 4 | 5 | 9 |
| 500 | 6 | 8 | 15 |
| 1,000 | 10 | 14 | 28 |
**Tip:** Always consider adding at least **one ADA-compliant unit** for every 20 standard units for accessibility.
