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. A porta-potty 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.
A restroom trailer is a towable unit with self-contained restrooms inside. It uses an onboard fresh water supply (or a hookup) for the sinks and flushing toilets, holds waste in an onboard tank that gets pumped on a service schedule, and runs on standard electrical power for lighting, climate control, and water systems. We deliver it, level it, connect it, and make sure it's ready before your crew or guests arrive.
A station is a usable spot where one person can be using the restroom at a time. On a two-sided trailer with separate men's and women's entrances, a urinal counts as its own station because multiple people use that side at once. On individual single-occupancy restrooms, each private room counts as one station regardless of the fixtures inside. So a 4-station trailer serves four people at once.
We offer restroom trailers in 3, 4, 5, 6, 8, and 10-station sizes, plus an 8-station Flex shower trailer. The smaller units are great for tight sites and smaller crews; the larger ones handle high-traffic commercial sites and big crews. See our trailers page for the full lineup.
It depends less on a fixed headcount and more on how hard the unit gets used and how often it's serviced. A single-shift crew needs less capacity than a site running two or three shifts around the clock. Tell us your crew size, your hours, and your service expectations, and we'll match you to the right unit — call 916-538-9044.
With two shifts, your trailer gets roughly double the use of a single-shift site, so servicing frequency matters as much as station count. For a crew that size we'd typically point you toward a larger multi-station unit with a service schedule to match, but the right answer depends on your exact hours and site. Call us and we'll size it precisely for your situation.
For remodels we keep it simple: we match like-for-like, replacing the number of stalls and urinals you're taking offline. Tell us what's coming out of service and we'll match it so you don't overpay for capacity you don't need or come up short.
There's no single magic number — capacity depends on usage intensity and how often the trailer is serviced. A trailer that's plenty for a light-use day gets used very differently on a round-the-clock site. That's why we size based on your real situation rather than a one-size estimate. The more service visits, the more people a given trailer comfortably supports.
Pricing depends on the trailer size, how long you need it, and how often it's serviced. A short commercial rental and a multi-month construction placement price very differently. The fastest way to get a straight, no-obligation quote for your project is to call the owner directly at 916-538-9044.
The main factors are trailer size (number of stations), rental length, servicing frequency (pumping, restocking, cleaning), delivery distance within Northern California, and whether the site needs extras like a generator or hot water setup. Tell us your project details and we'll give you a clear quote.
Yes. Most of our construction and commercial placements are monthly, with predictable billing and scheduled servicing. Projects run long and change, so extending is one phone call — no drawn-out runaround.
Our 3, 4, and 6-station trailers run on a single dedicated 20-amp, 110-120V circuit. The larger 8 and 10-station trailers have two air conditioning units and need two dedicated 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.
Yes. The onboard fresh water tank covers sites with no water spigot, and a correctly sized generator covers sites with no power. We just need a reasonably flat, accessible spot to place and level the trailer. Tell us about your site and we'll confirm what it needs.
You tell us the location, dates, and details. We deliver, place, and level the trailer, connect it, and make sure it's ready before your crew or guests arrive. When the project wraps, we pick it up. Need to extend? One call.
We serve all of Northern California, including the greater Sacramento region, the Sacramento Valley, the Sierra foothills, and the Tahoe and Truckee areas. See our locations page for specific cities — and if you don't see yours, call us; we likely cover it.
It depends on how hard the unit is used. Servicing — pumping the waste tank, sanitizing, and restocking — can range from once a week to several times a week for a busy crew. We'll recommend a schedule based on your crew size and usage when we quote the job.
It's flexible. Many long-term clients have their own janitorial staff handle daily cleaning and restocking, the same way they would with any on-site facility. But we can also take care of cleaning and stocking ourselves, or arrange it, depending on the site and what works for you. Either way, we handle scheduled pumping and service. We'll sort out the right arrangement when we set up your rental.
Yes. Our trailers have heaters and have been placed successfully in below-freezing conditions, which makes them a fit for foothill and mountain sites like Grass Valley, Auburn, Placerville, and the Tahoe-Truckee area. Cold-weather placement takes some planning — the trailer needs to stay powered and connected so the heat keeps the water lines from freezing — so call us and we'll set it up right.
Under OSHA's construction sanitation standard (29 CFR 1926.51), a site with 20 or fewer workers needs at least one toilet; above 20 workers the requirement scales to one toilet and one urinal per 40 workers, and at 200 or more workers, one toilet and one urinal per 50. Facilities must be kept sanitary and readily accessible. A single restroom trailer can provide several of these fixtures in one unit. Compliance is ultimately the employer's responsibility, so confirm your site's specific requirements — and we're glad to help you think through the right unit.
Yes. For restaurant and commercial remodels where OSHA requires hot water for employee hand-washing, we can set up hot water on the trailer. Just let us know it's required for your project.
Yes. We provide month-to-month rentals for distribution centers, retail and big-box locations, campuses, churches and community facilities, agricultural and seasonal operations, and any commercial site that needs dependable restrooms for the long haul.
Yes. We provide mobile shower trailers — including our 8-station Flex unit — for disaster and emergency response, fire camps, long-term industrial and agricultural sites, large construction crews, and major events. Each has private, climate-controlled shower stations with hot water.
Our Satellite Suites 8-Station Flex shower trailer 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. Unlike fixed-layout trailers, it adapts to your demographics on the spot.

Two things. First, every trailer arrives clean, fully stocked, and function-checked before it leaves the yard — we built the business around fixing the dirty, broken, understocked units we received renting from big outfits ourselves. Second, we're owner-operated: when you call, you reach the person who owns the equipment and stands behind every placement.

The trailer needs a reasonably flat, accessible spot — ideally level ground or pavement, clear of low branches and overhead power lines, with room for our service truck to reach it. For servicing, we need to get within about 25 feet of the trailer, and any water and power hookups should be within roughly 100 feet. Not sure if your site works? Tell us about it and we'll figure it out with you.
No — we handle it. We deliver, place, and level the trailer, connect it, and bring what's needed to get it running, including hoses and extension cords for the hookups. The trailer comes with an initial supply of toilet paper, hand soap, and paper towels. You don't need to prep the site beyond having an accessible, level spot.
Always. Every trailer is thoroughly cleaned, sanitized, fully stocked, and function-checked before it leaves our yard — that's the core of how we run. You should never receive a unit that's dirty, low on supplies, or with something broken. If anything isn't right when it lands, you call the owner directly and we fix it fast.
If your question isn't here, just ask. When you call NorCal, you reach the person who owns the equipment and manages every placement personally — straight answers, no runaround.
