Events & Festivals

For outdoor events, the standard ratio is 1 unit per 50–100 guests for a 4-hour event. Events with alcohol require 20–30% more units.

Construction Sites

OSHA requires 1 toilet per 20 workers. For crews over 20, add 1 unit for every additional 20 workers on site.

Weddings

We recommend 1 unit per 25–35 guests for weddings, plus at least one deluxe or restroom trailer for the bridal party.

Planning Tips

Book Early

Popular dates in San Antonio fill up fast. Reserve your units 4–6 weeks ahead for guaranteed availability.

Consider the Weather

San Antonio summers are hot! More hydration means more restroom use. Add extra units for summer events.

Include ADA Units

Always include at least one ADA-compliant unit. It's required for public events and appreciated by all guests.

Plan for Peaks

Events have peak usage times (after meals, during intermissions). More units reduce wait times during rushes.
