What is a flushing porta potty?
A flushing porta potty uses a foot pump to rinse the bowl with clean blue water after each use. The waste drops out of sight into the tank below. It also has a small sink with a foot pump, soap and paper towels. It is the same footprint as a standard unit, so it fits the same spots.

When is a flushing unit worth the upgrade?
A flushing unit is worth the upgrade for weddings, showers, family reunions and any party where guests stay 4 hours or longer. Guests do not see the tank, and the inside sink saves renting a separate hand-wash station for small groups. For dusty jobsites, a standard unit is the better value.

How many uses does a flushing unit handle?
A flushing unit handles roughly the same number of uses as a standard unit before pumping, but its fresh-water tank for flushing and the sink runs out sooner. For a 4- to 6-hour party, the tanks cover about 50 guests. Multi-day events need a refill visit each day.
Questions about flushing units
Does a flushing porta potty need a water hookup?
A flushing unit carries its own fresh-water tank. No hose or power is needed.
Can I use a flushing unit on a jobsite?
Flushing units can go on jobsites, but dust and heavy use empty the fresh-water tank fast. Most contractors use standard units plus a hand-wash station.
Is a flushing unit the same as a restroom trailer?
A flushing unit is a single portable toilet with a sink. A restroom trailer has porcelain toilets, vanities and lights, and needs power and level ground.
