The #1 Name in Temporary Restroom Trailers for Vallejo and Solano County
Vallejo is the largest city in Solano County, with about 123,000 people living where the Napa River meets San Pablo Bay. It is a city of ferries, an old Navy shipyard, a theme park, a maritime college and some of the most varied neighborhoods in America. We run the largest fleet of bathroom trailers in the West, over 250 units strong. We hold an A+ BBB rating and a wall of five-star Google reviews. We are licensed and insured, and we run a direct fleet that we own outright. We are not a reseller. Nobody farms out your job.
Strictly luxury. Never plastic. Each unit is a commercial-grade luxury restroom trailer with flushing china toilets, sinks with running water, mirrors, lights and its own air conditioning and heat. Tesla, Google, Target, eBay, Meta and Nvidia have booked our trailers, along with the Golden State Warriors and the Oakland A’s. With 30+ years of event and equipment rental behind us, we know what goes wrong on delivery day, and we plan for it before the truck leaves.
“The bathrooms at our wedding venue stopped working, and The Lavatory NorCal came through at the last minute with a trailer and a generator for power. I cannot say enough about how grateful we were. The night was saved.”
“Five stars. They gave our family reunion a great accessible restroom option, and our guests with limited mobility had a wonderful time because of it. They really keep their promise of comfort.”
Call (209) 202-3741 when the date is close or the problem is urgent. A real person on our NorCal dispatch team answers, checks which trailer is free right now and tells you when it can roll. For a wedding or festival a few months out, request a quote online and we will send a written price with the right size picked for your headcount. Already holding a quote from someone else? Send it over and we will review it for free.

What Every Private Stall Restroom Trailer Includes
Walk inside one of our units and it feels like a nice hotel restroom, not a construction toilet. Every room has a door that locks. The sink actually runs. Nothing smells, the floors are clean, and the lights stay on from the first guest of the afternoon to the last one leaving after midnight.
- A thermostat for cooling and heating in every unit
- China toilets that flush with a foot pedal
- Sinks with running water, soap and paper towels in every room
- Mirrors, counters and good lighting
- Built-in fresh water and waste tanks, so no plumbing is needed on site
- Outdoor lights above the doors and solid steel steps
The full lineup of portable bathroom trailer rentals for the North Bay shares these same finishes, from our compact two-room units up to the large multi-stall trailers we park at fairgrounds and festivals. Call us, or ask for a quote, and tell us the guest count.
Choosing a Luxury Restroom Trailer Size for a Vallejo Event
Headcount is only half the answer. A three-hour afternoon party and a nine-hour festival with a beer garden can draw the same crowd and need very different units. Use the guide below as a starting point, then call us and we will fine-tune it for your date, your site and the hours your guests will stay.
| Guests on site | Short event, under 4 hours | Long event or open bar | Room it takes |
|---|---|---|---|
| Under 100 | 2-stall unit | 2-stall or 3-stall unit | About 17 to 20 feet long with the hitch |
| 100 to 200 | 3-stall unit | 5-stall unit | About 20 feet long |
| 200 to 450 | 5-stall unit | 9-stall unit | About 20 to 26 feet long |
| 450 to 900 | 9-stall unit | 9-stall plus a second unit | About 26 feet each |
| Formal crowd of 400 to 600 | 8-stall private unit | 8-stall private unit with service | About 35 feet long |
| Any public event | Add an ADA plus 2 or ADA plus 6 unit | Same | About 25 to 31 feet with the ramp |
Garden parties in Glen Cove or Hiddenbrooke usually land on the 3-stall restroom trailer rental for Vallejo homes, which gives the women’s side two rooms and still fits most driveways. Church festivals, company picnics and school events often move up to the Solano County 5-stall portable restroom trailer. Formal receptions at wineries near American Canyon lean toward our 8-stall private stall bathroom trailer near Napa and Vallejo, where each guest gets a private room with a sink. For any public gathering, add the accessible ADA plus 6 restroom trailer in Solano County so every guest uses the same spot.
Waterfront and Downtown Vallejo Restroom Trailer Setups
Downtown Vallejo faces the Napa River, and most of its public life happens within a few blocks of the ferry terminal. The Saturday farmers market sets up downtown at 9 a.m. The Second Friday Artwalk has filled the historic district every month since 2014. Waterfront Weekend and Vallejo Fest bring crowds to the Barbara Kondylis Waterfront Green, an open lawn on the river with very few permanent restrooms. Runs, car shows, cultural festivals and church events fill other weekends, and the city’s mix of communities means the calendar stays busy all year instead of peaking once.
Downtown setups take some planning. The old street grid is narrow and parking is tight, so a compact two-room or three-room unit often fits better than a long trailer. Events on city property go through the City of Vallejo’s special event permit process, and the permit or site map usually shows where vehicles may enter the green. We deliver early in the morning before market stalls go up, place the trailer so its steps face the walkway, and keep the hitch side toward the street. Power can come from a nearby outlet with permission, or from a quiet generator we bring and park away from the stage.
For an all-day festival on the green, we often pair a 9-stall unit near the food vendors with an accessible ramped unit close to the main path. For a two-hour art walk reception at a gallery or a church hall, one 2-stall unit on a side street is usually enough. Tell us the cross streets and the expected crowd, and we will tell you what fits before you file the permit.
Races start here too. A local run club meets at the ferry terminal every Saturday morning and Wednesday evening, and charity 5Ks use the waterfront path and Mare Island’s long, flat streets. Start lines need a lot of restrooms for a short burst of time. We park one or two large units near the start, light them before dawn and keep the heat on. Lines move fast. Runners notice.
Mare Island: Portable Restroom Trailers for the Old Navy Shipyard
Mare Island was the first Navy base on the West Coast. It opened in 1854, built and repaired ships and submarines for more than 140 years, and closed in 1996. Today the island is a slow, steady redevelopment project with a university campus, small factories, shops, a brewery, government offices and acres of open shipyard ground. Old landmarks still stand, including Dry Dock No. 1 from 1891 and St. Peter’s Chapel from 1901. The island also hosts big outdoor fairs on its promenade and waterfront, including Maker Faire Bay Area.
Much of that open ground has no working restrooms nearby. Old buildings are fenced off, new ones are still going up, and the distances are long. A self-contained mobile restroom trailer with its own water and its own waste tank solves that on day one. For renovation crews, we park a unit inside the fenced work area and service it weekly. For film and TV shoots, which use the island’s old streets and brick buildings as sets, we place trailers at base camp and move them when the company moves. For a fair on the promenade, we stage several large units along the main walkway.
Getting there takes local knowledge. Highway 37 west of Mare Island sits close to sea level through the marsh, and it has flooded and closed before, including a levee break in 2019 that shut the westbound side for five days. When that road is out, we come onto the island from the Vallejo side over the Mare Island Causeway or the Highway 37 bridge from the east. Our drivers check road conditions before every winter delivery, so your trailer arrives on time either way.
Deluxe Bathroom Trailers at the Fairgrounds, Theme Park and Local Campuses
The Solano County Fairgrounds sit in the middle of Vallejo, and their barns and open lots host far more than the county fair. Touring circuses, holiday markets, car shows, swap meets and cultural festivals book the grounds through the year, some for a single weekend and some for weeks at a time. Long runs like that need restrooms that stay clean for the whole engagement, not just opening day. We set the trailers near the gates and the food court and put them on a service schedule that matches the show days.
Just across the road, Six Flags Discovery Kingdom runs more than 60 rides plus animal shows, and it adds fall weekend events through October. Large parks like that still rent extra restrooms for staff areas, private company days, backstage zones and construction projects. Vallejo’s school district runs two large high schools, Vallejo High and Jesse M. Bethel, along with many elementary and middle schools, and graduations and sports nights pack their fields. Cal Maritime, on a 92-acre campus by the Carquinez Bridge, fields 14 varsity teams that include sailing, crew, rugby and water polo. Solano Community College opened a Vallejo campus in 2018, and Touro University California holds classes on Mare Island.
Campus and venue jobs reward a vendor that shows up on time and stays out of the way. That is our whole approach. We plan delivery around class schedules and gate hours, use the service road the facility manager picks, and service units early in the morning. When a school’s restroom wing closes for a remodel, a trailer at the back of the building keeps the school day running without anyone walking across campus.
Bathroom Trailers for Hospital, Plant and Highway Projects in Solano County
Health care is Vallejo’s biggest employer. The Kaiser Permanente medical center and its call center employ more than 3,500 people, and Sutter Solano Medical Center adds about 600 more. Hospital campuses remodel, retrofit and expand all the time, and a closed restroom wing in a hospital or a clinic is not a small problem. A temporary restroom trailer at a staff entrance keeps nurses, workers and visitors from walking across a busy campus, and we service it on a schedule that avoids patient drop-off hours.
Road and plant work fills the rest of the list. The new I-80 express lanes between Red Top Road in Fairfield and Leisure Town Road in Vacaville opened in December 2025, and the state has approved more work farther east. Plans to widen Highway 37 between Mare Island and Sears Point will keep crews busy for years. Across the strait, Benicia’s refinery and industrial park schedule planned shutdowns that bring in hundreds of contract workers. California’s construction sanitation rule, Title 8 Section 1526, ties the number of toilets on a job site to the number of workers, and our flushing trailers with running water meet that need in a way that keeps people on the job and in a better mood.
For job sites, we set the service rhythm by headcount, usually weekly for a small crew and two or three times a week for a large one. Every visit includes a pump-out, fresh water, a full cleaning and new supplies. When the work moves down the highway, the trailer moves too. One phone number covers all of it.
Strait Wind, Mild Summers and Heat Spikes: Climate Control in Our Vallejo Restroom Trailers
Vallejo is mild most of the year. January averages around 46 degrees, July averages under 70, and the breeze off the bay keeps the city roughly 10 degrees cooler than Fairfield or Sacramento. That mild average hides two things that matter on event day. Wind pours through the Carquinez Strait on many afternoons, which pushes on doors and steps. A few times each year, the sea breeze stops. Then an offshore heat wave can push temperatures far above normal for several days in a row, which is exactly when a hot trailer would empty a party.
We plan for both. On windy sites, we park with the doors on the sheltered side and set the steps firmly so they do not shift. When a heat wave is in the forecast, we start the air conditioning early and plan the power so it holds through the afternoon. In winter, about two feet of rain a year softens lawns and dirt lots, so we bring boards for the wheels and turn on the heat before guests arrive. Simple steps. Big difference.
Fire Camps, Outages and Emergency Restroom Trailers Across the North Bay
Wildfires in the hills around Vallejo do not need to reach the city to change everything. In 2020 the LNU Lightning Complex burned more than 363,000 acres across Solano, Napa, Sonoma, Lake, Yolo and Colusa counties, and its largest piece, the Hennessey Fire, ran through the hills between Napa and Solano. In 2017 the Atlas Fire burned across both Napa and Solano counties. Fires like these fill shelters, cooling centers and base camps with people who need clean restrooms for days or weeks, and planned power shutoffs can take restrooms offline in buildings that never saw a flame.
When an emergency hits, call our 24/7 line. We can often be there within 1 to 2 hours with rapid same-day deployment for shelters, staging areas, schools, care homes and fire camps. Our emergency restroom trailer rentals for Solano and Napa counties work alongside mobile shower trailer rentals near Vallejo when evacuees stay overnight, and with temporary laundry trailer rentals for North Bay base camps when a camp runs for weeks. Every trailer carries its own water and can draw power from a generator, so it works before the grid comes back. The federal Ready.gov power outage guide is a good checklist for any building manager planning ahead for a shutoff.
Not every emergency is a fire. A water main breaks under a school. A sewer line backs up at a care home on a Friday night. A restaurant fails its plumbing inspection the week before a big catering job. In each case, people still need a restroom tomorrow morning, and a building with no working toilets usually has to close until it gets one. We get those calls all the time, and we treat them like the emergencies they are, with a trailer on site and working while the plumber is still digging. Fast help. No drama.
Restroom Trailer Rentals for Cultural Festivals, Church Fiestas and Community Days in Vallejo
A 2012 Brown University study named Vallejo the most diverse city in the United States, and the latest census shows no single group making up even a third of the population. You can see it on the calendar. Filipino, Mexican, Black, Pacific Islander and many other communities hold their own festivals, church fiestas, parades, family reunions and heritage days in parks, parish lots and school fields across town. Most of these gatherings are run by volunteers, and the restroom question usually lands on one busy organizer a few weeks before the date.
We make that part easy. One call covers the size, the delivery time, the power and the pickup, and we can bill the parish, the club or the nonprofit directly. For a park or a church lot with a few hundred guests, a 5-stall unit plus an accessible ramped trailer is a common pair. For a parade route, we place units near the staging area and the reviewing stand. Food booths, live music and long afternoons mean heavy use, so we plan a midday check for any event longer than six hours. Your volunteers can focus on the food and the music.
Backyard, Vineyard and Hillside Parties With a Deluxe Bathroom Trailer
Family parties are a big part of life in Vallejo. Baptisms, quinceañeras, debuts, graduations, anniversaries, memorials and backyard weddings bring 80 to 200 guests to a single home. One hall bathroom was never built for that. A trailer in the driveway keeps guests out of the house and keeps lines short. Most homes have a garden hose and an outdoor outlet within 100 feet, which is all our smaller units need.
Hillside streets in Hiddenbrooke and the north end of town can be steep, and some driveways have tight turns or low trees. Send a photo of the spot when you ask for a quote and we will tell you right away whether the trailer fits, or suggest a better place. Winery and ranch weddings in American Canyon, Green Valley and the Napa side often have no restroom building, so we bring the water and the power with us and level the unit on grass or gravel. If your homeowners association has street rules, we keep the trailer on your own property.
A 2-stall bathroom trailer for Vallejo backyard parties covers up to about 150 guests and draws its power from a single outdoor outlet. Larger groups move up a size. Either way, we deliver before the party and pick up after, with no cleanup left for you.
Timing matters in wine country. Weddings and winery parties around American Canyon and Napa cluster from May through October, and harvest season adds crush parties and staff dinners in the fall. Saturdays in those months book early, so a call four to six weeks ahead gives you the widest choice of trailers. Weekday and Sunday dates are easier. If your date is close, call anyway, because cancellations and returns free up units every week and our dispatch team always knows what is open.
Three Typical Vallejo Restroom Trailer Rentals From Call to Pickup
Each job is its own. Still, most Vallejo rentals follow one of these three patterns, and seeing them laid out side by side makes it easier to picture the timing, the trailer count and the service plan for your own event or project.
A waterfront festival on the green
A festival group expects 3,000 visitors over one Saturday. They book two 9-stall trailers and an ADA plus 6 unit. We deliver at dawn through the access point on the permit map, connect to generators set behind the vendor row, and fill the water tanks. A service tech checks and restocks at midday. By 9 p.m. the trailers are gone and the lawn is clear for Sunday.
A four-month renovation on Mare Island
A contractor restoring an old shop building has 35 workers on site. The site manager orders one 5-stall trailer inside the fence near the time clock. We service it twice a week, refill the water and restock supplies. When the project moves to a second building, we tow the trailer down the block. The crew never has to leave the island to find a restroom. Simple.
A family celebration in Glen Cove
A family hosting 150 guests for a milestone birthday books a 3-stall trailer. We park it on the driveway Friday, hook it to the hose and an outlet, and level it on boards. The heat comes on Saturday evening as the fog rolls in off the strait. We pick it up Sunday afternoon, after the last tables are folded.
Five-Star Reviews for Our North Bay Restroom Trailers
“I went to my cousin’s wedding and the venue bathrooms quit working. You would think these folks were first responders by how fast they got there. I have never seen people so excited about a bathroom. Thanks for saving the night.”
“Great customer service and on time for every delivery and service visit. The driver went above and beyond to make sure the trailer was set up to our site’s standards. Thank you to the whole team.”
“I ordered the five-stall trailer at the last minute for my parents’ anniversary. I was a little skeptical at first, but it worked out great. We will use them again.”
“Very nice and clean luxury restroom. I rented one for my son’s baptism party and everyone loved it. I will definitely be calling them again.”
“I had a very smooth experience with this company. I rented a restroom trailer for my 40th birthday party and they did not disappoint. I will recommend them to everyone.”
“With a lot of people at an event, having these restrooms meant nobody waited ten minutes in line. Very clean, very convenient, and the team made it easy.”
How Renting a Temporary Bathroom Trailer in Vallejo Works
- Call or request a free quote. Share the date, the address, how many people and how long the trailer stays. Our phones are open 24/7.
- We size it. We pick the right unit, confirm power and water, and flag anything about the route, like a narrow downtown street or a fairgrounds gate.
- We deliver and level it. Our driver parks the trailer, levels it, sets the steps or ramp, connects power and water, and tests every fixture.
- We service it. For long events and job sites, we pump, refill, clean and restock on a set schedule.
- We haul it out. We pick it up when you say, and we leave the spot as clean as we found it.
There is no second vendor to hire. We bring the generator when one is needed, pump the tanks ourselves and clean the rooms with our own staff. The price on your quote is the price you pay, with transparent pricing and no surprise fees added at the end. If your plans change, call us. We can swap sizes, add a unit or move a date as long as the trailer is free.
Have a few facts ready when you call and the quote takes minutes. We will ask for the address or venue name, plus the date and hours. We also need the number of people you expect at the busiest moment. We will also ask whether the ground is paved, gravel or grass, and how far the nearest outdoor outlet and hose bib sit from the spot you picked. If the event is on city, county or fairgrounds property, have the permit or the site contact handy. That is it. Short list.
Common Questions About Bathroom Trailer Rentals in Vallejo
Do you deliver to Fairfield, Suisun City and Travis Air Force Base?
Yes. We cover all of Solano County, including Fairfield, Suisun City, Vacaville, Dixon and Rio Vista. Deliveries onto a military base follow the base’s own gate and escort rules, so tell us the gate when you book.
My venue has power but no water. Will the trailer still work?
Yes. Every trailer has its own fresh water tank, which we fill before or at delivery. For long events, we top it off on service visits, so you never need a hose bib.
Can you leave a trailer at a church or community hall for a whole weekend of events?
Yes. Weekend and week-long rentals are common for church festivals, revivals and community fairs. We service the unit between days so it opens clean each morning.
Do you work with film and TV productions?
Yes. Productions on Mare Island and around the North Bay rent our trailers for base camps and set locations. We can move units between locations on your schedule and work around early call times.
What if my guest count grows after I book?
Call us. We can switch you to a larger trailer or add a second unit as long as one is free on your date. The earlier you tell us, the easier the change.
Can I rent a trailer for a celebration of life at home?
Yes, and we will keep it simple for your family. We deliver the day before, set the trailer out of the way, and pick it up after the gathering without anyone needing to be home.
How do I add an accessible restroom to a public event in Solano County?
Ask for an ADA plus 2 or ADA plus 6 unit when you call. Both have a ramp and a roomy unisex accessible room, plus regular stalls, so everyone uses the same trailer.
Will the trailer be ready if my event starts early in the morning?
Yes. For early starts, we deliver the day before or at first light, then check the lights, the water and the temperature so the rooms are ready when the first guest walks up.
