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.
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.

Straight answers about how our restroom trailers work. Don't see yours? Call the owner directly.
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.
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.
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.
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.
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.
When you call NorCal, you reach the person who owns the equipment and manages every placement personally — someone who knows your kind of project and can get you the right unit. Straight answers, direct accountability, no runaround.

Beyond restrooms, we provide mobile shower trailers for crews that need to stay clean on site.
Built for high-volume needs — disaster response, fire camps, long-term industrial and agricultural sites, and large crews. Unlike fixed-layout trailers, the "Flex" design uses a central hallway with internal locking doors, so the space can be reconfigured on the fly to match your crew — all-male, all-female, or any split you need, adjusted instantly. Eight private shower stations.
Climate-controlled, with hot water and private locking stalls.
Need a different configuration? We can source the right shower unit for the job — just ask.
