200-person Oktoberfest, beer all day: how many porta potties?

For a 200-person Oktoberfest with an 8-hour duration and alcohol, rent at least 12 to 15 portable toilets. This count starts from the planning guideline of one unit per 50 to 75 people for a four-hour event, then adds units for the longer duration, the presence of alcohol, and a mixed-gender crowd. You must include at least one ADA-compliant portable toilet in the cluster to satisfy the ADA 5 percent cluster rule.

A restroom trailer offers a better guest experience with flushing toilets and sinks but requires a power source, level ground, and a water supply. A trailer can serve as the primary facility, possibly reducing the number of standard units needed, or it can supplement them. For this event length, plan for a mid-event service visit to pump tanks and restock supplies regardless of unit type; alcohol consumption increases usage and will fill holding tanks faster. The rental cost is driven by the type of units, the rental duration, the service frequency, and the delivery distance.
