What is the main difference between a restroom trailer and a porta potty?
A restroom trailer has real flushing toilets, sinks, lights and climate control, and needs power, water and level ground. A porta potty is a self-contained unit with no hookups that can go almost anywhere. A trailer costs about 7 times a standard porta potty for a weekend.
| Standard porta potty | Deluxe flushing unit | Restroom trailer | |
|---|---|---|---|
| Starting price | $175 | $275 | $1,250 (2-stall) |
| Hookups | None | None | 110-volt outlet + hose |
| Guests per unit (4 hrs) | About 50 | About 40–50 | About 50 per stall |
| Flush and sink | No | Yes | Yes, porcelain |
| Ground | Any firm spot | Any firm spot | Level, firm, truck access |
When is a restroom trailer worth the cost?
A restroom trailer is worth the cost for weddings, corporate events and parties of 100 or more where guests dress up, stay into the evening and expect an indoor-style bathroom. Trailers also suit multi-day events and shelters where people need lights and climate control.
When is a porta potty the better choice?
Porta potties are the better choice for job sites, casual parties, races, festivals, soft or sloped ground, and any spot with no power or water. They cost less, set up anywhere, and many units can be spread around a large site to shorten lines.
Middle ground: deluxe flushing units give guests a flush and a sink without hookups.
