What's the difference between a flushing porta potty and a deluxe unit?

A flushing portable toilet and a deluxe portable toilet are distinct unit types with different primary features. A flushing-unit has a toilet that flushes with fresh water into a holding-tank, but it does not typically include an internal sink. A deluxe-unit is a non-flushing unit that includes a handwashing sink with running water, a mirror, and sometimes more interior space. For a guest's experience at an upscale event, the internal sink often makes a bigger difference than a flushing toilet. The ability to wash hands with running water inside the private unit is a significant comfort and hygiene upgrade.

Regarding service, a flushing unit typically needs more frequent service-visits under heavy use. The flushing action uses water, which increases the liquid volume in the holding tank and can fill it faster than a standard non-flushing unit. For a five-hour event with 150 guests, the industry guideline suggests starting with more than the baseline number of units due to the dinner, open bar, and duration. The rental cost is driven by the unit type's features, the rental duration, and the required service frequency.
