Why The Lavatory NorCal Is the #1 Portable Bathroom Trailer Company in San Jose

Strictly luxury. Never plastic. We rent only commercial-grade bathroom trailers, and because we own every unit we deliver, you deal with a direct fleet instead of a broker who hands your order to whoever is free that day. Our family has spent 30+ years in event and equipment rental. Companies like Google, Tesla, eBay, Target, BMW and Mercedes have used our trailers, and so have the Golden State Warriors and the Oakland A’s. Hundreds of five-star reviews back that up.

San Jose is a big city to cover. It spreads across about 181 square miles, from the Alviso marsh at the top of the bay down to Coyote Valley, and from the Evergreen foothills across to the Almaden hills. Our drivers know the routes, the freeway timing on 101, 280, 680 and 87, and which side streets a long trailer can actually turn into. Call us with your date and address and we will give you a quote the same day. If you would rather send the details in writing, use the quote form and we will call you back quickly with sizes and delivery times.

Private Stall Bathroom Trailers and Every Other Size We Haul to San Jose

Most San Jose jobs land in one of seven sizes. The table gives the guest range we plan around and the power each unit needs, so you can see in a minute which trailer fits your head count and your site.

3-stall bathroom	2 women’s, 1 men’s	225 guests and under	One 20 amp, 120 volt circuit

The 8-stall private bathroom trailer for big San Jose events is the one we bring when a crowd wants real privacy. Every door opens into its own room with a toilet, a urinal and a sink, so there are no shared lines by gender and no waiting outside a men’s side while the women’s side sits empty. It carries 400 gallons of fresh water and a 1,000 gallon waste tank, which matters on a long festival day downtown. For a smaller party, the 3-stall restroom trailer for South Bay backyards gives women two rooms and men one, which matches how lines actually form at a wedding.

What You Get Inside Each Deluxe Restroom Trailer

Walk up the steel steps, hold the rail, open a real door. Inside, the floor is solid and level. The walls are one-piece fiberglass that wipes clean in seconds. On a hot September afternoon, the kind of day that pushed San Jose to a record 109 degrees in 2022, the air conditioner keeps the room cool, and on a cold January night the same unit works as a heater. The toilets are white china with a foot flush. The sinks are stainless steel with hot and cold water, set under a big framed mirror and good lighting, so nobody fixes their hair by phone light. Paper towels, soap, toilet paper and a fresh scent are all stocked before the trailer leaves our yard.

• Air conditioning and heat with a digital thermostat
• Flushing china toilets, plus urinals in the men’s rooms
• Stainless sinks with running water and framed mirrors
• Interior and exterior LED lights for evening events
• Onboard fresh water and waste tanks, so no hookup is required
• Steel stairs with platforms and rails at every entry

San Jose Service Area Map for Temporary Bathroom Trailers

We deliver to every San Jose ZIP code and to the cities around it, and we deliver anywhere in the country when a job calls for it. These are the parts of town where our trailers show up most.

Close by, we cover Santa Clara bathroom trailer rentals near the stadium district, Milpitas, Campbell, Cupertino and temporary restroom trailers in Sunnyvale from the same South Bay routes, and across the bay we run daily to Fremont luxury bathroom trailer rentals and the rest of the East Bay. Call (209) 202-3741 with your address and we will tell you the delivery window on the spot.

Luxury Restroom Trailers at Downtown Venues, Arenas and Fairgrounds

Downtown San Jose fills up in summer. Plaza de Cesar Chavez hosts Fountain Blues and Brews in late June, Music in the Park in late July, and San Jose Jazz Summer Fest, which ran August 7 to 9 in 2026 with more than 100 performances and free outdoor stages. From Thanksgiving to New Year’s the same park turns into Christmas in the Park. The city’s own restrooms were never sized for those crowds, and promoters who place a 9-stall or an 8-stall private bathroom trailer behind the vendor row see shorter lines and fewer complaints by the second hour.

Arena and stadium nights bring a different setup. Around SAP Center, PayPal Park and Excite Ballpark, we usually stage on a paved lot or a loading area, and we set delivery for the morning so we are long gone before fans arrive. The convention center downtown draws trade show load-ins that run late into the night, with crews who need a clean restroom near the dock. Out on Tully Road, the 165-acre Santa Clara County Fairgrounds hosts the Tet Festival each winter and the county fair in August (August 19 to 23 in 2026), plus concerts, trade shows and rodeos. Big lots there are easy to reach, and we can line up several trailers on one service plan.

For public events on city streets and in downtown parks, the city runs a special event permit through its Office of Cultural Affairs, and the City of San Jose special events office asks for the application at least 45 days before the event. We send a site sketch with trailer sizes, power needs and the service route, which helps your permit move along.

Fitting a Portable Restroom Trailer at Homes and Hillside Lots Around San Jose

Private parties make up a big share of our work in San Jose. Think graduation parties in Berryessa, quinceaneras in East San Jose, big birthday parties in Almaden Valley, memorials in Cambrian, and weddings in Willow Glen backyards where the house has two bathrooms and 140 guests are on the way. A clean, private bathroom trailer keeps guests out of the house, keeps the septic or the old sewer line from backing up, and keeps the host from spending the night checking the toilet paper.

The hard part is usually the driveway. Willow Glen and the Rose Garden have narrow drives and low tree limbs. Evergreen and the Silver Creek hills have steep grades. Almaden lots often sit behind gates with tight turns. Send us a photo or a satellite pin and we will tell you which trailer fits: the 2-stall is 17 feet long with the tongue, and the 3-stall is just under 20 feet. Once it is in place, we level it on jacks so the doors close square and the sinks drain the right way. Then we run the cord to a garage outlet on its own breaker, or we bring a quiet generator and park it out of earshot.

Not sure which size works for your yard? Call (209) 202-3741, tell us the guest count and the hours, and get a free quote in the same call.

Parks, Trails and Lakes: Temporary Restroom Trailers for San Jose Park Events

San Jose’s parks host a steady run of company picnics, charity walks, family reunions, church festivals and youth tournaments. Kelley Park alone holds Happy Hollow Park and Zoo, History Park and the Japanese Friendship Garden. Lake Cunningham anchors the east side, Alum Rock Park is one of the oldest city parks in California, and Guadalupe River Park follows the river right through downtown. Almaden Lake, Emma Prusch Farm Park and Overfelt Gardens draw their own crowds on summer weekends.

Park restrooms tend to be small, far from the picnic area and locked at dusk. That is where a temporary restroom trailer helps. We park on a lot, a service road or a paved pad, never on soft turf without boards, and we keep the cord run short and taped down so nobody trips on the way to the food line. Large gatherings in city parks go through the city’s San Jose parks permit for festivals and large events, and we can send the trailer details your reservation asks for. A 5-stall covers most reunions and picnics. Bigger walks and tournaments usually pair a 9-stall with an accessible unit near the finish line or the parking lot.

Multi-Stall Bathroom Trailers for San Jose Construction, Transit and Campus Projects

The biggest project in town right now is BART Silicon Valley Phase II, the six-mile extension that will carry trains from Berryessa under downtown to Diridon and on to Santa Clara. Work on the tunnel launch structure at Newhall Yard is well along, and station work is lined up at 28th Street and Little Portugal, at Diridon and downtown over the next few years, with the line planned to open in the late 2030s. Jobs like that run for years, with crews, inspectors and office trailers that all need restrooms better than a row of plastic boxes on a muddy lot.

We also see steady work in North San Jose and Edenvale, where office buildings get gutted and rebuilt, warehouses get new tenants, and manufacturers shut down a restroom core for a plumbing upgrade. Campus jobs at San Jose State and the school districts follow the summer break. For any of these, Cal/OSHA’s construction toilet rule in Title 8, section 1526 sets the floor at one toilet for every 20 workers of each sex. The ADA plus 2 handles a crew of about 30, and a 5-stall or 9-stall covers more. We put the unit near the site office, set a weekly or twice-weekly service day, and pump, refill and restock without stopping the job.

Company Picnics, Launches and Conferences With a Deluxe Bathroom Trailer

San Jose is the home base for Cisco, Adobe, PayPal, Zoom and eBay, and dozens of other tech firms keep offices along North First Street and in the Edenvale business parks. That means a long calendar of outdoor all-hands meetings, product launches, holiday parties in parking structures and family days on a campus lawn. Conferences are getting bigger too. In March 2026, the Nvidia GTC conference spread out from SAP Center into the blocks around it, with more than 30,000 people expected.

Corporate events want a clean look and no surprises. We send our certificate of insurance before the event, schedule delivery around badge gates and security escorts, and place the unit where it is easy to find but out of the photos. The 8-stall private bathroom works well here because every room is unisex, so the line moves evenly no matter who is in it. Facility teams also call us when a building’s restroom core is shut for repairs, and a deluxe bathroom trailer by the side entrance keeps everyone at their desks.

Emergency Restroom Trailers for Floods, Outages and Heat Waves in Santa Clara County

In February 2017, Coyote Creek overflowed after Anderson Reservoir began spilling, and about 14,000 San Jose residents were told to leave their homes. Rock Springs, Naglee Park and Brookwood Terrace took the worst of it, and firefighters pulled more than 200 people out by boat. Floods like that leave shelters, schools and apartment blocks without working plumbing for days or weeks. Water main breaks, sewer failures and long power cuts do the same on a smaller scale, and every summer brings heat waves that hit the east side and Evergreen hardest.

When that happens, call us first. We answer 24/7, we keep units staged for the South Bay, and we can often be there within 1 to 2 hours with a trailer that is already filled with fresh water and stocked. Our emergency restroom trailers for Bay Area outages and floods run on their own tanks, so they work even when the building’s water is off. For apartment managers, property owners and public agencies, we can set several units in a parking lot and keep them serviced until the repairs are done.

Power outages are the other big emergency here. High winds in the hills and summer heat can knock out service for hours or days, and PG&E can shut off power ahead of fire weather. Senior housing, clinics, schools and offices lose working restrooms fast when pumps and lift stations stop. Because our trailers carry their own water, and because we can bring a generator along, a restroom trailer keeps working through an outage that shuts the building down. We have staged units for property managers through long repair jobs, and we keep doing the service runs until the building is back to normal.

Power, Water and Weather Planning for a Mobile Restroom in San Jose

Power comes first. The 2-stall, 3-stall and 5-stall each need one dedicated 20 amp, 120 volt circuit within 100 feet. The 9-stall, the 8-stall private bathroom and the ADA plus 2 need two. A garage outlet works fine as long as nothing else, such as a pool pump or a fridge, shares that breaker. If your site has no power, we bring a generator. Water is simpler, since every trailer carries its own fresh tank, and a garden hose can keep it topped up on a long rental.

Weather here is kind most of the year. San Jose sees close to 300 sunny days and about 16 inches of rain, nearly all of it from November through March. Winter storms soften lawns and dirt lots, so we lay plywood under the jacks. Summer is dry, and the AC matters most in August and September. If the trailer has to sit on a public street for more than a short stop, check with the city about a permit first. Most of our San Jose rentals avoid that by parking in a driveway, a side yard or a private lot.

Accessible Restroom Trailers for San Jose Venues and Public Sites

Any public event, city job or large private party should plan for guests who use a wheelchair, a walker or a cane. Our ADA plus 2 bathroom trailer has one women’s room and one men’s room. Its third room is an accessible unisex room at the end of the trailer, reached by a self-contained ramp built to the California standard. The ADA plus 6 adds six more private stations, so one trailer covers a big crowd and accessible access at the same time. Both are built to federal ADA requirements and California’s accessibility code.

Placement matters as much as the trailer. The ramp needs a flat landing at the bottom with room to turn a wheelchair, and the path from the parking lot or the main walkway should be firm, not loose gravel or wet grass. We set the accessible unit closest to the main path, never tucked behind a larger trailer, and we check the ramp angle and the railings before we leave. If you are not sure your site works, send us a photo and we will tell you what it needs.

How Many Restroom Trailer Stalls a San Jose Event Needs

Start with the head count and the hours. The guest ranges in our size table assume a normal event of about four to five hours. If the event runs longer, size up. If there is an open bar or beer garden, size up again, since people visit the restroom more often once drinks start flowing. Lines also form at breaks. A ceremony that ends at once, a halftime or a keynote that lets out all together sends everyone at the same moment, so a trailer that looks big enough on paper can still back up for ten minutes.

Women’s lines run longer than men’s at almost every event. That is why our standard trailers give the women’s side more stalls, and why the 8-stall private bathroom, with its unisex rooms, is so popular at mixed crowds. For a wedding of about 200 guests with dinner and dancing, a 5-stall is the usual pick. A street fair with a few thousand people moving through over a day usually needs two or more 9-stalls, plus an accessible unit near the entrance. On job sites, the count follows the crew size and the Cal/OSHA ratio above.

Tell us the details. We size it for you. It costs nothing to ask, and we would rather add a trailer on paper than have your guests waiting in a long line at nine o’clock.

San Jose Bathroom Trailer Questions, Answered

Can you set a trailer near Plaza de Cesar Chavez or another downtown venue?

Yes. We work inside street closures and on venue lots downtown all the time. The event’s city permit covers the placement, and we provide the trailer sizes and a site sketch for your application.

Which trailer gives guests the most privacy?

The 8-stall private bathroom. Every one of its eight rooms is unisex and fully private, with its own toilet, urinal and sink behind a locking door.

Will a trailer fit up a steep Evergreen or Almaden driveway?

Often, yes. The 2-stall is 17 feet long with the tongue and the 3-stall is just under 20 feet. Send us a photo of the driveway and we will confirm before delivery day.

Do you deliver to Milpitas, Campbell, Los Gatos and Morgan Hill?

Yes. We cover all of Santa Clara County and the cities around San Jose, and we can deliver anywhere in the country for larger jobs.

How fast can you get a trailer to a flooded or broken building?

We run 24/7 immediate dispatch with same-day delivery, and for urgent calls in San Jose we can often be there within 1 to 2 hours. The trailer arrives filled with fresh water and fully stocked.

How many trailers does a large festival need?

It depends on the crowd size, the hours and whether alcohol is served. As a starting point, one 9-stall covers 400 to 900 people over a five hour event. We will build the full plan with you on the phone.

Can a restroom trailer stay on a job site for months?

Yes. Long-term rentals are a big part of our work in San Jose. We set a regular service day to pump the waste tank, refill the fresh water and restock supplies for as long as the project runs.

How far ahead should I book for a summer weekend?

For June weddings, graduation weekends and the big downtown festivals in August, booking a few weeks out is smart. Last-minute calls still happen every week, and we fill them whenever a trailer is free.

Do you bring a generator if the venue has no outlet?

Yes. Many park lots and empty job sites in San Jose have no power, so we bring a quiet generator sized to the trailer and place it away from the crowd.

Can you send a certificate of insurance for a corporate campus?

Yes. We are licensed and insured, and we send the certificate your facility or event team needs before delivery day.
