Flushing Porta Potty Rental in the Phoenix Area
A flushing porta potty looks like a standard unit from outside but adds a foot-pump flush that rinses the bowl with fresh water from a separate tank. Many add a small sink. It still needs no hookups, and guests notice the difference right away.

The flush hides the holding tank, which is most of what people dislike about portable toilets. That makes it a common upgrade for backyard parties, church events and weddings where a trailer is not in the budget.
Because the fresh water tank runs out, high traffic can outpace it. For long, busy events, ask whether the operator will check and refill mid-event.
Quick facts
Best uses for a flushing porta potty
What to ask the operator
- How many flushes does the fresh tank hold?
- Does this unit include an inside sink?
- Can you refill water during the event?
Valley tip: Freezing nights in high desert areas can affect fresh water tanks. In the Valley that is rare, but ask for winter events north of the metro.
