Top-Rated 3-Stall Luxury Bathroom Trailer Rentals in Northern California
Every trailer we rent is a luxury unit. No plastic boxes. Our family has worked in event and equipment rental for 30+ years, and because we own every trailer we send out, the same company that answers your call also delivers, levels, cleans and services the restroom until the final pickup. Google, Tesla, Target, BMW and eBay have rented from our fleet, and so have the Golden State Warriors. We hold an A+ rating with the BBB, we are licensed and insured, and our five-star Google reviews keep arriving from customers everywhere between Marin County and the Placer County foothills.
The 3-stall sits in the middle of our lineup. It serves up to 225 guests at a party, or a work crew of about 40, and the compact build is shorter and lighter than most bathroom trailers with the same number of rooms. Call us with the date, the address and a rough head count, and you will have an honest quote the same day. If you would rather type it out, send the quote form and someone from our dispatch office will call you back quickly.

Three Private Rooms in One Compact Bathroom Trailer: Layout and Specs
The floor plan puts the two women’s rooms side by side and the men’s room at the hitch end. Each room has its own door and its own folding steel stairs, so three people can come and go at the same time without waiting in a shared hallway or squeezing past each other at a single entrance. One rooftop air conditioner cools and heats the entire trailer.

What Guests Find Inside the Portable Restroom Trailer
Guests open the door and find a small, bright bathroom that looks like it belongs in a beautifully finished home. There is a corner vanity with a steel sink and a tall framed mirror, framed botanical art on the wall, a wood-look floor and a real china toilet that flushes with a foot pedal, so nobody has to touch a handle. The men’s room adds a wall urinal next to the toilet. Fans move the air, and the thermostat holds the room where you set it, whether that means a 100 degree September afternoon in Lodi or a damp, windy evening on the Sonoma coast. We stock every room with toilet paper, paper towels and hand soap before the trailer leaves our yard. Outside, LED lights over each door keep the stairs easy to see after sunset, which matters at a vineyard or a ranch where the nearest street light might be a mile down the road.
Shorter and Lighter: Why This Temporary Bathroom Trailer Fits Tight Sites
Length is the first thing we check. Our compact 3-stall measures 16 feet 3 inches long with the tongue, about 3 feet shorter than a full-size 3-stall, and it weighs 4,640 pounds on a single axle, roughly 1,400 pounds less than the larger version. That difference decides a surprising number of deliveries in this part of California.
Think about a barn venue off a one-lane gravel road in west Sonoma County, a hillside home above Mill Valley where the driveway turns twice before it levels off, or an estate in the Santa Cruz Mountains with an old wooden gate that a long trailer simply cannot swing through. The shorter body makes those turns, and the lighter weight is easier on brick paths, lawns and soft ground after the first winter rains. At 7 feet 6 inches wide, it also slides into a side yard or a slot between a barn and a hedge that a bigger unit would block. Send us a photo of the drop spot, along with any narrow gates or overhead wires you know about. We will tell you on the first call whether it fits.
How Many People One 3-Stall Bathroom Trailer Serves
For a party, a reception, a memorial or a company picnic, plan on up to 225 guests over about five hours. Three toilets plus a urinal move a line along much more quickly than a single women’s room ever could, which is the main reason so many customers step up from a 2-stall once their guest list grows. Open bar? Long day? Add a little cushion. A tight, short event can run a bit over the number, and a long, hot one should stay under it.
On a work site, the 3-stall covers a crew of about 40 on a normal shift. California sets the floor for workplaces in Title 8, and the Cal/OSHA toilet facility rule in section 3364 ties the number of toilets to the number of workers, with hand washing close by. We look at your head count, your shift length and your service schedule, then tell you honestly whether one trailer is enough or whether a second unit, or a larger size, makes more sense for the location.
Still deciding between sizes? Call (209) 202-3741 with your guest list and hours. We will match the trailer to the job, and the quote costs you nothing.
Common 3-Stall Rental Setups in Wine Country, the Foothills and the Bay
We deliver this trailer all over the region, and a few kinds of jobs keep coming back every year. These are typical setups based on many deliveries, not one particular customer’s story.
A barn wedding near Sebastopol
A couple books a family apple ranch for 180 guests. The barn has one restroom and a septic tank that was originally designed for a single farmhouse, and the only way in is a narrow gravel lane lined with old fence posts. We tow the compact unit down the lane, set it on the flat spot by the orchard, and run power from the barn panel on its own circuit. Guests climb stairs with sturdy railings instead of stepping into a plastic box, and the barn septic never sees the crowd.
An Apple Hill harvest weekend in El Dorado County
From September into December, the farms and wineries around Camino see weekend crowds their old restrooms were never built for. A family farm stand keeps the 3-stall at the edge of the pie barn parking area for the entire season, and our service technician comes out midweek to empty the waste tank, refill the fresh water and restock every room. Visitors stop asking where the bathroom is.
A tenant improvement job in downtown Oakland
A general contractor guts the restrooms on two floors of an office building for a code upgrade. About 35 electricians, plumbers and drywall installers are on site each day, and the street is too narrow for a long trailer. The 3-stall fits in a single parking space plus the stairs, the building engineer connects it to an exterior outlet, and we service it twice a week until the new bathrooms pass their final inspection.
Our wedding and special event restroom trailers in Sonoma and Napa page covers bigger venues that use more than one unit. For short or long jobs on a building site, see our temporary restroom rentals for NorCal job sites, which lays out weekly and monthly service.
Renting a Mobile Restroom Trailer, Step by Step
- Call or send the form. Reach us at (209) 202-3741. Share the address, the dates, the head count and how you plan to power it.
- We size it for you. We confirm the 3-stall is right for the crowd and the space, or steer you to a better fit, and send a free quote with no hidden fees.
- We drop it and level it. The driver backs the trailer in, levels it on its jacks, sets all three stair sets, connects power and water, and tests each flush and light.
- We keep it serviced. On multi-day rentals our technicians empty the waste tank, refill the fresh water and restock paper and soap on a regular schedule.
- We pick it up. When the job ends we hitch up, haul it out and leave your site clean.
Hookups and Ground Prep for a Deluxe Restroom Trailer
Power comes first. The 3-stall needs one dedicated 120 volt, 20 amp circuit within 100 feet, which is often a garage or barn outlet that has nothing else on it during the event. A coffee urn, a pool pump or a string of bistro lights on the same breaker can trip it, so ask your electrician or walk the panel with us. No power at the site? We bring a quiet generator. In late summer and fall, PG&E can cut power in high fire risk areas, and the CPUC’s page on Public Safety Power Shutoffs explains how those warnings work, so a generator is a smart backup for foothill and wine country dates.
Water is simpler. The 105 gallon fresh tank covers most one-day events, and a garden hose connection keeps it full on longer jobs, while the 350 gallon waste tank is emptied during our regular service visits. For the ground, choose a location that is close to level, firm enough for a loaded truck, and clear of low branches or overhead wires. Asphalt, gravel and concrete work best. If the trailer will sit on a city street, check whether your city requires an encroachment permit before delivery day.
Unsure about your site? Call (209) 202-3741 any time, day or night. Most site questions get answered in one short call.
Reviews From NorCal Customers Who Rented Our Luxury Restrooms
“These guys saved my wedding! Our venue in the Placer County foothills had no bathrooms, and we hated the idea of porta potties for our guests. The units were clean and stocked with soft toilet paper, so we never worried about smells or long lines.”
“For my mom’s 60th and retirement party we rented a small venue in Sacramento, then found out it had one tiny bathroom for 200 guests. The Lavatory NorCal came highly recommended and did not disappoint. Great service and quick replies. I knew I could count on them.”
“We had a large backyard gathering in San Ramon and they brought a trailer that was tidy and simple to use. The staff was professional and setup was quick. It made the whole event feel more polished.”
“Very happy with the trailer and the service. I didn’t notice the generator and water weren’t part of my order until hours before delivery, and they were understanding and brought both at no extra charge. The bathrooms were nice and everything worked great.”
“We used a restroom trailer for a family event out by Lake Berryessa, and I was surprised how tidy and cozy it was. It felt less like a portable restroom and more like an indoor one.”
Other Bathroom Trailer Sizes and the NorCal Cities We Serve
The 3-stall is one size in our full line of luxury portable bathroom trailer rentals in Northern California. For a smaller backyard or a crew under 20, the two-room 2-stall bathroom trailer is the easiest unit to place. When the list grows past 225, the 5-stall restroom trailer for larger NorCal crowds adds two more toilets. If you need a wheelchair accessible room, the ADA plus 2 restroom unit with a ramp pairs one accessible room with two standard stalls.
Our drivers cover the East Bay, the Sacramento region and the North Bay every week. We handle Oakland bathroom trailer rentals from the hills to the port, the luxury restroom trailers we deliver around Roseville and Placer County, and the portable restroom rentals in Vallejo and Solano County. We also deliver anywhere in the country. Browse every city on our list of Northern California restroom trailer service areas.

3-Stall Portable Bathroom Trailer FAQ
Why pick a 3-stall over a 2-stall?
The third room. With two women’s rooms instead of one, the line that usually forms at weddings and parties moves about twice as fast, and the compact trailer still fits into most of the same locations as the smaller unit.
Can a pickup truck tow it onto my property?
We handle all the towing with our own trucks and experienced drivers, so you never need a hitch or a heavy vehicle. You only need a clear path about 12 feet wide and a firm, reasonably level spot to park it.
Does the trailer need a water hookup?
No. The 105 gallon onboard tank handles most single-day events. A hose hookup is handy on multi-day rentals, and we can also refill the tank on service visits.
Is it comfortable on a hot Sacramento day?
Yes. The rooftop air conditioner cools all three rooms during Central Valley heat waves and switches over to heat on cold nights, and our driver sets the digital thermostat during delivery so your guests never have to adjust anything.
How soon can you get a 3-stall to me?
We offer same-day delivery with 24/7 immediate dispatch, and we can often be there within 1 to 2 hours for urgent calls. For weekends in May, June and October, booking a few weeks early is wise.
Can I keep it for a month or longer?
Yes. Long rentals are common for office remodels, school construction and seasonal agricultural sites, and we schedule a weekly or twice-weekly service visit so the trailer stays clean and fully stocked the entire time.
