2026 fall festival: does a 4-stall trailer need a separate generator?

Yes, a 4-stall restroom trailer requires a separate generator to operate its lights, flushing toilets, and heater for 12 hours when no park power hookup is available.

The rental company will specify the generator size, but a typical 4-stall trailer needs a generator that provides at least 5,000 to 7,000 watts of continuous power. A generator of this size handles the simultaneous load of the water pump for flushing, LED lighting, and the electric heating element without tripping a circuit. The rental company usually offers a generator as a separate rental item, not as an included feature. The generator rental cost is driven by its size, fuel consumption, and delivery. You must place the generator downwind and at a safe distance from the restroom trailer to reduce noise and exhaust intrusion.

For your festival with 2,000 people, food, and beer, the 4-stall trailer alone may not meet the demand. Event planning guidelines suggest starting with one unit per 50 to 75 people for a four-hour event and adding more for alcohol, longer duration, and food service. Consider adding standard or deluxe portable toilets to form a cluster and include at least one ADA-compliant portable toilet to comply with the ADA 5 percent cluster rule.
