Planning portable restrooms for an outdoor event requires attention to guest count, event duration, and accessibility requirements. Use this checklist to ensure your event has adequate restroom facilities.
Pre-Event Planning Checklist
- Determine expected guest count
- Calculate event duration in hours
- Identify if alcohol will be served (increases restroom usage)
- Check if food vendors will be present
- Review venue layout for placement options
- Confirm delivery and pickup access routes
Calculating Number of Units
The general rule for outdoor events is one porta potty per 50 guests for a 4-hour event. Adjust based on these factors:
Quick Formula:
(Number of Guests ÷ 50) × (Event Hours ÷ 4) = Minimum Units
Example: 200 guests for 6 hours = (200÷50) × (6÷4) = 4 × 1.5 = 6 units
(Number of Guests ÷ 50) × (Event Hours ÷ 4) = Minimum Units
Example: 200 guests for 6 hours = (200÷50) × (6÷4) = 4 × 1.5 = 6 units
Factors That Increase Requirements
- Alcohol served: Add 20-25% more units
- Food-heavy event: Add 10-15% more units
- Majority female attendance: Add 15-20% more units
- Events over 6 hours: Consider mid-event servicing
Placement Checklist
- Location is visible but not too close to food areas
- Ground is level and stable
- Units face away from main event area
- Clear signage directing guests to restrooms
- Adequate lighting for evening events
- Service truck access path is clear
- Minimum 10 feet from food service areas
Accessibility Requirements
Events open to the public should include ADA-compliant units:
- At least one ADA unit for events with 50+ guests
- ADA units placed on firm, level ground
- Clear path of travel to ADA units (36" minimum width)
- No steps or barriers to access
- Units positioned for wheelchair approach
Event Day Checklist
- Confirm units were delivered and positioned correctly
- Check that all units are stocked with supplies
- Verify doors open and close properly
- Test hand sanitizer dispensers
- Place directional signage if needed
- Note rental company emergency contact number
Post-Event
- Confirm pickup time with rental company
- Ensure access path remains clear for pickup
- Note any issues for future events
