Things To Consider When Planning How Many Portable Restrooms To Rent
Consider these factors when planning your portable sanitation needs:
- OSHA requirements:
- For 1 to 20 workers: At least one portable toilet
- For 20 to 190 workers: At least one toilet seat and one urinal for every 40 workers
- For 200 or more workers: One toilet seat and one urinal per 50 workers
- Event duration: Multi-day events may require more porta potties or regular servicing.
- Crowd size: Larger gatherings (500, 1,000, 5,000+ people) need strategic restroom placement. Portable restrooms should be placed near entrances and exits and be free of obstructions.
- Handicap requirements: There should be at least one handicap-accessible, ADA-compliant restroom for every 20 portable restrooms (a ratio of 5%). The path to the restroom must also be accessible and clear of curbs, steps or other impediments for people with disabilities.
- Special events: Hand-washing stations and our more luxurious restroom trailers are ideal for event planners looking to enhance the event experience. We recommend adding 10% to 20% more porta potties at events where alcohol is available.
