What is the difference between a porta potty and a restroom trailer?
A porta potty is a self-contained, single-person unit with a holding tank and no hookups. A restroom trailer is a towed building with 2 or 4 flushing stalls, sinks with running water, lights and climate control. The restroom trailer needs power, water and room for a truck.
A standard porta potty can go almost anywhere a person can walk it on a dolly. A restroom trailer is closer to a small indoor bathroom, and it needs a site that can take a pickup-towed trailer.
Between the two sits the deluxe flushing porta potty. The deluxe unit has a flush and a built-in sink but still needs no power or hose.

When is a porta potty the wrong choice?
A standard porta potty is the wrong choice when guests expect an indoor-style bathroom: formal weddings, client events and long evening parties with older guests. At those events, people avoid a basic unit, and lines form at the one nice option. A trailer or deluxe flushing unit fits better.
- Formal dress. Long gowns and suits do not fit well in a 43.5-inch-wide unit.
- Long, cold or dark evenings. A trailer has lights and heat; a standard unit has a translucent roof.
- Guests who need a sink. If you skip the trailer, add a hand wash station or choose the deluxe unit.
- Client-facing corporate events. Running water and mirrors matter to guests in work clothes.
When is a restroom trailer the wrong choice?
A restroom trailer is the wrong choice when there is no 120V 20-amp outlet within 100 feet, no level 20-by-8-foot spot, or no route for a towed trailer. A restroom trailer also does not suit job sites, wheelchair users who cannot use steps, or a small budget.
- No power. A trailer without power has no lights, fan, heat or pumps. A generator plan has to be confirmed ahead of time.
- Backyards behind a gate. A trailer cannot squeeze through a side gate the way a standard unit can.
- Soft or sloped lawns. The trailer must sit level, and a wet lawn may not hold a tow vehicle.
- Job sites. Mud boots and tools are hard on vanity sinks. A job site toilet on weekly service fits that use.
- Wheelchair users. Trailer stalls are reached by steps, so add a wheelchair-accessible unit at ground level.
Can I mix a restroom trailer and porta potties?
Mixing is often the best setup. A restroom trailer near the tent serves guests, while 1 or 2 standard porta potties near parking serve vendors, staff and late-night overflow. Add 1 wheelchair-accessible unit and a hand wash station so every guest has a usable option.
Here is one example for a 150-guest wedding that runs 6 hours with a bar. Our sizing method calls for 7 standard units. A 2-stall trailer can cover the guest side, with standard units, an accessible unit and hand wash stations making up the rest. Run your numbers with the porta potty sizing calculator.
For public events, 2010 ADA Standards section 213.2 requires at least 5% of portable units in each cluster to be accessible. A trailer with steps does not count toward that.
Wedding-specific planning, including where to hide the units in photos, is on the wedding porta potty rental page.
How do I decide in two minutes?
Answer four questions: Is a 120V 20-amp outlet within 100 feet? Can a truck tow a trailer to a level 20-by-8-foot spot? Will guests dress up or stay past dark? Is the budget over about $1,000? Four yes answers point to a restroom trailer. Any no points to porta potties.
- Check power: an outdoor outlet on its own 20-amp circuit within 100 feet.
- Check access: a driveway or road to the spot, no low branches, no soft lawn.
- Check your guests: formal, older, or staying late in cool weather.
- Check the budget: compare a trailer to the deluxe flushing unit, which starts at $245 for an event.

Common questions
Does a restroom trailer need electricity?
A restroom trailer needs a 120V 20-amp outlet within 100 feet for lights, fans, heat and pumps. The trailer also needs a garden hose or an onboard fresh tank fill. A standard porta potty needs neither.
Are restroom trailers wheelchair accessible?
Most 2-stall and 4-stall restroom trailers are reached by steps, so guests who use wheelchairs need another option. Pair the trailer with a ground-level wheelchair-accessible unit on a firm, level path.
Can a restroom trailer go in my backyard?
A restroom trailer can go in a backyard only if a truck can tow the trailer there and the spot is level, about 20 by 8 feet. Side gates and soft lawns usually rule that out. A deluxe flushing unit fits through wider gates.
Is a flushing porta potty the same as a restroom trailer?
A flushing porta potty is a single unit with a recirculating or fresh-water flush and a small sink, but no power or hookups. A restroom trailer has multiple stalls, vanity sinks, mirrors, lights and climate control.
How far ahead should I book a restroom trailer?
Book a restroom trailer 1 to 2 weeks ahead for May through October weekends and weddings. Weekend trailers are delivered Friday and picked up Monday at no extra charge.
