Restroom Trailers From 3 to 10 Stations

Six restroom trailer sizes plus mobile showers — matched to your site, your crew, and how hard the unit will get used. Every one arrives clean, stocked, and working.

Not sure what size you need?

Capacity isn't really a single number. A trailer that's plenty for a day-shift crew gets used very differently when a site runs two or three shifts around the clock — so the real question isn't just "how many people," it's how hard the unit gets used and how often it's serviced. For remodels and renovations, we keep it simple: we match like-for-like, replacing the number of stalls and urinals you're taking offline. Tell us your situation and we'll size it right the first time.

When water isn't conveniently available on site, all our trailers have onboard fresh water tanks that can be filled — so a missing hookup doesn't stop your project.

Doing a restaurant or commercial remodel? We can set up hot water to meet OSHA hand-washing requirements for your employees — just let us know it's needed.

Trailer FAQ

Common Questions About Our Trailers

Straight answers about how our restroom trailers work. Don't see yours? Call the owner directly.

What's the difference between a restroom trailer and a porta-potty?

A restroom trailer is a fully enclosed, climate-controlled facility with flushing toilets, running-water sinks, interior lighting, and finished interiors — much closer to an indoor restroom than a standard porta-potty, which is a single plastic unit with no running water or climate control. For crews, staff, or guests you want to keep comfortable over time, a trailer is the better fit.

How much power does a restroom trailer need?

Our 3, 4, and 6-station trailers run on a single dedicated 110V 20-amp circuit. The larger 8 and 10-station trailers have two air conditioning units and need two 20-amp circuits. If a site has no power available, the trailers can also run from a correctly sized generator.

Do restroom trailers need a water hookup?

They run best with a standard garden-hose water spigot, but it isn't a dealbreaker. When no water hookup is available on site, every trailer carries an onboard fresh water tank we fill for you, so a missing hookup doesn't stop your project.

How far in advance should I book a restroom trailer?

Sooner is better, especially during busy months, but we move quickly when we can. The fastest way to check availability for your dates is to call the owner directly at 916-538-9044.

Can a restroom trailer be used in cold or freezing weather?

Yes. Our trailers have heaters and have been placed successfully in below-freezing conditions. Cold-weather placement does take some planning — the trailer needs to stay powered and connected so the heat keeps the water lines from freezing — so for a foothill or mountain site, call us and we'll plan it out with you.
