Porta Potty Types Compared: Which Unit Should You Rent?
Five unit types cover almost every rental. A standard porta potty fits most job sites and parties. A flushing unit with a sink suits dressy events. A wheelchair-accessible unit is required at public events. A hand wash station goes with food. A restroom trailer suits receptions with water and power.
What are the differences between porta potty types?
Porta potty types differ in 5 ways: flushing, handwashing, accessibility, hookups and space. Standard and accessible units use a chemical tank with no flush. Flushing units add a foot-pump flush and sink. Restroom trailers add real plumbing, lights and climate control but need water and power.
| Unit | Best for | Flushing | Handwashing | Space & hookups |
|---|---|---|---|---|
| Standard porta potty | Job sites, backyard parties, remodels, long rentals | No (chemical tank) | Hand sanitizer inside | 44 in wide; fits a 48-in gate |
| Flushing unit with sink | Weddings, showers, nicer parties | Foot-pump flush | Sink with running water inside | Same footprint as standard; no hookups |
| Wheelchair-accessible unit | Public events, churches, older guests, job sites | No (chemical tank) | Sanitizer; add a hand wash station | About 7 ft square; needs an 8×8 ft level spot |
| Hand wash station | Any event with food; crews (OSHA handwashing) | — | Two-sided sink, soap, towels | About 3 ft square; no hookups |
| Restroom trailer | Weddings, VIP areas, long outages at businesses | Real flush toilets | Sinks, mirrors, lights, climate control | Hose + 20-amp outlet or generator; level ground |
Which porta potty type fits my job?
The right porta potty type depends on who uses it and for how long. Crews and remodels need standard units with weekly service. Parties need standard units plus hand washing when food is served. Weddings need flushing units or a trailer. Public events need at least 1 accessible unit.
| Situation | Recommended setup | Avoid |
|---|---|---|
| Roofing crew of 6, 3 weeks | 1 standard unit, weekly service | Flushing unit (fresh tank runs out) |
| Graduation party, 120 guests, food + beer | 4 standard + 1 hand wash station | Only 1 unit |
| Barn wedding, 150 guests, power + hose | 2-stall trailer + 2 flushing units | Trailer on soft field after rain |
| Church festival open to the public, 300 people | 6 standard + 1 accessible + 2 hand wash | Zero accessible units |
| Bathroom remodel, family of 4 | 1 standard (or flushing) unit on the driveway | Placing on the tree lawn without asking the city |
What are the hookup and space needs for each type?
Standard, flushing and accessible units need no hookups and sit on a level spot from 4 by 4 feet to 8 by 8 feet. Hand wash stations need about 3 by 3 feet. Restroom trailers need about 8 by 16 feet, a garden hose and a 20-amp outlet or generator.
- All units need the truck within about 25 feet for service and pickup.
- Standard units fit a 48-inch gate; accessible units and trailers do not go through gates.
- Every unit needs level ground; a tilted unit leaks and the door will not close right.
Questions renters ask
Is a flushing porta potty worth the extra cost?
A flushing unit is worth it for dressy events where guests expect a sink and no view into the tank. For job sites and casual parties, a standard unit plus a hand wash station costs less and works well.
Do you have high-rise or crane-lift units?
We do not stock crane-lift units. For upper floors, place standard units at ground level near the hoist or stair tower.
What is a towable porta potty?
A towable unit is a standard porta potty on a small trailer, so a crew can move it with a pickup as the work zone moves. Ask for one for road, pipeline or utility crews.
