The general rule is one unit per 10 workers for a 40-hour work week. For sites with 20+ workers, or crews working overtime, add units accordingly. Cal-OSHA §1526 requires a minimum of one toilet per 20 employees. We’ll recommend the right count during your quote — just tell us your crew size and project duration.

For events, plan one unit per 50-75 guests for a 4-hour event. Add more for longer events, if alcohol is served, or if food is being served. VIP restroom trailers serve 75-150 guests depending on the model. Call us with your guest count and event details — we’ll quote the exact setup.

Yes. Standard weekly service works for most sites, but we offer twice-weekly and daily service for high-traffic crews. Multi-weekly service improves worker comfort, job site conditions, and crew morale. It’s a small investment that sets your site apart. We’ll help you determine the right frequency during the quote process.
