Strategic Placement Guide

Where you place portable restrooms significantly impacts guest experience. Follow these placement principles:

Do's

• Spread units throughout the venue – Don't cluster all restrooms in one area
• Place near high-traffic areas – Entrances, bars, and food stations
• Position on flat, stable ground – Avoid slopes and soft terrain
• Keep accessible units in prime locations – Near main event area with clear pathways
• Allow for service truck access – Leave room for pumping equipment

Don'ts

• Don't place near food preparation – Minimum 50 feet from catering areas
• Don't block pathways or exits – Keep emergency routes clear
• Don't position at event focal points – Keep away from stages, altars, or photo backdrops
• Don't place in low-lying areas – Avoid potential flooding spots

Types of Units for Events

Standard Porta Potties

Best for casual outdoor events, festivals, and large gatherings. Cost-effective and practical for high-volume use.

Deluxe Flushable Units

Feature hand-washing stations, mirrors, and fresh-water flushing. Ideal for corporate events and upscale gatherings.

ADA-Compliant Units

Larger units with wheelchair accessibility, grab bars, and lower fixtures. Required for public events and recommended for all occasions.

Restroom Trailers

Climate-controlled trailers with multiple stalls, running water, and premium finishes. Perfect for weddings and VIP events.

Event-Day Management Checklist

Common Mistakes to Avoid

1. Underestimating unit needs – Always round up, especially for events with alcohol
2. Booking too late – Popular weekends fill up quickly; book 4–6 weeks ahead
3. Forgetting ADA units – Accessibility isn't optional; always include at least one
4. Poor placement – Units too far from the action lead to guest complaints
5. Skipping mid-event service – Long events need servicing to maintain quality
6. No lighting plan – Dark restroom areas feel unsafe and lead to accidents
7. Ignoring weather – San Antonio storms can flood poorly placed units

Budget Planning Tips

Make the most of your portable restroom budget:

• Book early for the best rates and availability
• Bundle services – Delivery, pickup, and mid-event service often cost less together
• Right-size your order – More units than needed waste money; fewer create problems
• Consider timing – Off-peak seasons may offer better pricing
• Mix unit types – Use standard units for volume and a few deluxe for VIP areas
