Why Our Private Stall Bathroom Trailer Is the #1 Choice in NorCal
Eight doors. No line. That is the short version. The long version is that a crowd of several hundred people moves through this trailer far faster than through a men’s side and a women’s side, because anyone can take the next open door and nobody waits on the busy half while the other half sits empty. We are a direct fleet with 30+ years in event and equipment rental. We own every unit we rent, so there is no broker taking a cut, no farmed-out job and no surprise company showing up on delivery day. Tesla, Meta, Amazon, Chevron and the Golden State Warriors have all used trailers from our fleet. We are licensed and insured, carry an A+ BBB rating and have five-star reviews from customers all over the state.
Each unit goes through a 120-point inspection before it leaves the yard, and our fleet is kept young, with trailers three years old or newer. Call us with your date, the address and a head count, and you will have a quote the same day. Prefer to type it out? Send the quote form and our dispatch team will call you right back.
“Great service. We used the private stall trailer for a company event in Mountain View and the restrooms were clean all day. The team was on top of every detail and really gave us the luxury experience we wanted.”
“We depend on The Lavatory NorCal for all of our restroom needs, and they never let us down. For our big festival in Sacramento the 8-stall private trailer gave us plenty of rooms, and the quick arrival and setup made our job much easier.”

How Eight Locking Rooms Keep the Mobile Restroom Line Short
Most multi-stall units split guests by gender, with two or three toilets on each side of a shared room. That works until halftime, intermission or the end of a work shift, when one side backs up out the door and the other side stays half full. The Private Stall Deluxe drops the split. Every one of the eight rooms is unisex and walled off from the next, with its own entry stair and handrail outside. A person walks up, takes whichever door shows open, locks it and has the whole room to themselves.
That layout is why the unit is rated for 400 to 600 guests at an event. It also solves problems you might not expect. Families can use one room together. A guest who needs a little more time is not holding up a shared space. On a job site, a worker in a harness or a full set of gear has room to deal with it in private. Short version? Faster turns.

Each room gets the same finish you would find in a nice office building. Floors have a wood look. Walls are bright white fiberglass that wipes clean in seconds, and every counter holds a steel sink with hot and cold water under a framed mirror. Two separate climate units cover the length of the trailer, so the rooms at the far end stay as cool on a 105 degree July afternoon in Davis or Rancho Cordova as the rooms by the hitch. When the evening wind comes off the bay in Alameda or Richmond, the heat side of those same units takes over.
Where a Large Luxury Restroom Trailer Earns Its Keep in Northern California
This is our high-volume unit. Crowds welcome. It shows its value wherever a lot of people need a real bathroom at the same moment, whether that is a county fair crowd or a refinery shutdown. In the Bay Area that means big street fairs and outdoor concerts in Golden Gate Park and along the Oakland waterfront, tailgate lots around Levi’s Stadium in Santa Clara, and company picnics on the tech campuses of Menlo Park, Cupertino and Mountain View. Up the valley, it fits the fairground weeks at Cal Expo in Sacramento, the Alameda County Fairgrounds in Pleasanton and the Sonoma County Fairgrounds in Santa Rosa.
Industrial work is the other big half. Refinery turnarounds in Richmond, Martinez and Benicia bring hundreds of contract workers onto a site for weeks, often on two shifts, and data center builds around Santa Clara and San Jose keep large crews on the job six days a week. Port and rail work near West Oakland needs facilities that hold up to heavy use, and so do levee repair in the Delta and long highway projects along Interstate 80. The hard hats and vests on the wall hooks in the photo above are no accident: this unit spends a lot of its life on job sites.
Then there are the calls nobody plans for. Wildfire base camps, evacuation centers, atmospheric river flooding and planned power shutoffs can leave a building or a whole neighborhood without working restrooms for days. Our team rolls out 24/7, and the large tanks on this trailer mean fewer service trips while a site is getting back on its feet.
Not sure your head count calls for eight rooms? Call (209) 202-3741 and walk us through the event or the shift schedule. We will size it with you, and the quote costs nothing.
Typical Private Stall Trailer Setups We See Around the Region
These are common patterns from our NorCal deliveries. Every site differs a little, though the shape of the job tends to repeat, and we plan each one with the customer before the truck leaves the yard.
A refinery turnaround in Contra Costa County
A plant near Martinez brings in about 300 contractors for a five-week maintenance shutdown, working day and night shifts. The safety manager wants restrooms close to the gate so workers are not walking half a mile in gear. We set the Private Stall Deluxe on the contractor lot, run it off a generator, and pump and restock three times a week. Workers hang their hard hats on the hooks inside each room, and the shift change no longer turns into a fifteen minute wait.
A 400-guest estate wedding in Napa
A large reception on a Napa Valley estate has a dance floor, a full bar and guests who stay until midnight. The venue’s two indoor restrooms would never keep up. Not a chance. We park the trailer behind a hedge near the tent, light the stairs, and the planner puts a small sign out front. Since every room is unisex and private, grandparents and parents with small kids use it without a second thought.
An outdoor all-hands on a Peninsula tech campus
A tech company in Menlo Park or Palo Alto hosts 600 employees on its lawn for a summer party with food trucks and a band. The building restrooms are a long walk from the field. Too far. One trailer covers the afternoon, and the facilities team likes that nobody has to stand in a gendered line while the other side sits open.
Planning Power, Water and Space for a 35-Foot Deluxe Restroom Trailer
This is a big rig, so the site matters. Measure first. With the tongue on, the trailer measures 35 feet, and with all eight stairs folded down it is a little over 12 feet wide, so plan for a clear pad about 40 feet long with room along the door side for people to line up. The truck that tows it needs space to swing in and back out, which can be tight on a narrow vineyard road in Sonoma or a steep drive in the Berkeley hills. Send us a photo or a map pin and we will tell you in one call whether the spot works. We confirm the truck route too, including gates, overhead wires and soft shoulders.
Power comes from two dedicated 120 volt, 20 amp circuits within 100 feet. If the site has none, we bring a quiet generator and we place it far enough away that nobody hears it. The 400 gallon fresh tank and the 1,000 gallon waste tank give you a long stretch between service visits, and we set the pump schedule to your head count. For work sites, federal rules on sanitation for general industry are in OSHA standard 1910.141, which is a useful check when you are planning for a large crew. During fire season, the California Public Utilities Commission’s power shutoff page explains how planned outages work, and a generator backup is worth asking about if your date falls in late summer or fall.

Reviews of Our Private Restroom Trailers
“We have used The Lavatory NorCal for 13 months on a project in San Jose with large numbers of people every day. They have been dependable the whole time, kept up the quality of their work and stayed in close touch with our teams on site. The trailers are a classy step up from a regular portable bathroom.”
“We had a large Scouting event in the Santa Cruz Mountains and needed extra restrooms. I think theirs got used more than the ones at the camp because of how nice they were. Delivery was easy too.”
“These luxury restrooms were a lifesaver on our film set near Petaluma. They were warm shelter when the wind got bad, and after a long day on set a clean private room beats a dirty porta potty every time. We hope to see these again on future shoots.”
“It has made a real difference for our crew in Richmond. Having reliable restroom access means everyone stays focused on the job without walking off site, and the day goes a lot smoother.”
“We expected roughly 200 people at our event in Concord. The company was very professional, the rooms were extremely clean, and they answered every question fast. Highly recommend.”
Other Portable Bathroom Trailer Sizes and the NorCal Cities We Cover
The Private Stall Deluxe is the biggest private-room unit in our Northern California portable bathroom trailer rentals lineup. If you would rather have separate men’s and women’s sides for a crowd of a similar size, the 9-stall luxury restroom trailer for big NorCal events is the closest match. For a smaller guest list, the mid-size 5-stall bathroom unit often does the job. When your permit or your guests call for a wheelchair room, pair this trailer with the ADA plus 6 accessible bathroom trailer with a ramp.
Our trucks are out every day across the region. We handle restroom trailer rentals in San Francisco and up the Peninsula, Oakland temporary bathroom trailers for the East Bay, and large bathroom trailer rentals in Santa Clara for stadium and campus events. Inland, we cover luxury restroom trailers for Sacramento events along with Roseville, Elk Grove, Chico and the towns in between. When pipes break or the power goes out, see our emergency bathroom trailer service in Northern California, and check the every NorCal restroom trailer service area for every city we reach.

Common Questions About the 8-Stall Private Bathroom Trailer
Are all eight rooms unisex?
Yes. Every room is a private, single-user bathroom with a locking door, so anyone can use any room. If your event wants signs for men and women, we can label some doors for you.
How much open ground does the trailer need?
Plan on a firm, fairly level pad about 40 feet long and 15 feet wide, plus a clear path for the truck to back in. Paved lots, packed gravel and firm grass all work in dry weather.
How long can it go between service visits?
It depends on use. With a 1,000 gallon waste tank, a one-day event of a few hundred guests usually needs no service at all, while a busy job site often gets pumped two or three times a week.
Can the trailer work off a generator?
Yes. It needs two 20 amp circuits, and we can supply a generator sized for both AC units, the lights and the pumps when there is no power on site.
Is there a wheelchair accessible room inside?
No, the stalls are reached by stairs. For accessible access, we add an ADA plus 2 or ADA plus 6 trailer next to it, which is a common setup at public events and city-permitted sites.
How quickly can you deliver it in an emergency?
Dispatch is open 24/7 with same-day delivery, and for urgent calls we can often be there within 1 to 2 hours. For festival and wedding season, booking early is still the safe move.
