Bathroom Trailer Rentals in Pomona, Los Angeles County

The Lavatory Los Angeles is the #1 name for bathroom trailer rentals in Pomona, with luxury units ready for job sites, weddings, film shoots, school projects, emergencies and any job, any size. We own over 250 units, the largest fleet of bathroom trailers in the West, so a clean, climate-controlled trailer is ready when your date or your deadline moves. Call (818) 593-0069 any hour. We can often be there within 1 to 2 hours, or you can request a free quote and hear back fast.

Every unit we send to Pomona is a real trailer: flushing china toilets, running water, stainless sinks, framed mirrors, bright lights, and heat and air conditioning. Strictly luxury. Never plastic. The trailer that shows up looks like a nice indoor restroom, and our service schedule keeps it that way for the whole job.

• Largest fleet in the West: over 250 luxury bathroom trailers, from the compact 2-station to the 9-station.
• Same-day delivery: 24/7 immediate dispatch to every Pomona neighborhood, plus the rest of Los Angeles County.
• Direct owner, never a broker: the people who quote your job are the people who deliver, clean and pick up the trailer.
• 99.6% incident-free: each unit passes a 120-point inspection before it leaves the yard.

Pick a size. We take care of the rest. A 2-station bathroom trailer for Pomona backyards fits a driveway on a quiet street, and a 5-station bathroom trailer rental in Pomona covers most receptions and job sites of 150 to 450 people. When a site must serve wheelchair users, the ADA plus 2 bathroom trailer for Pomona job sites brings its own ramp. Call us for a quote today, or send the quote form and we will price the right unit for you.

Why Choose The Lavatory Los Angeles for Luxury Bathroom Trailer Rentals in Pomona

Plenty of companies can drop a plastic box on a lawn. We do one thing: premium restroom trailers, kept like a hotel lobby restroom, delivered by our own drivers. Our family has worked in event and equipment rental for more than 30 years, and the fleet we built is the biggest of its kind in the Western U.S. Here is what that means on a Pomona job.

• Newer units. Our fleet runs about three years old or newer, so you get clean walls, working fans and tight doors.
• Clear quotes. Transparent pricing with no hidden fees. Already have a quote from another company? Send it over and we will review it for free.
• Real people on the phone. Our dispatch line answers 24/7, and the same team handles your job from the first call to pickup.
• Fast response. Typical response times run 45 to 90 minutes, and we can often have a trailer on site within 1 to 2 hours.
• Set up right. Every unit is leveled, connected, stocked and climate-controlled before your first guest or worker walks up.

Every room is stocked before we leave: soft toilet paper, hand soap, paper towels and a light fragrance. Inside you will find white china toilets with foot flush, stainless steel sinks with running water, large framed mirrors, LED lights and wall art. Onboard tanks hold the fresh water and the waste. That means the units work almost anywhere, even on a dirt pad with no water line.

Where Our Luxury Bathroom Trailers Go in Pomona, Street by Street

Pomona is a big city with very different streets, where historic homes sit a few blocks from freeway warehouses and hillside tracts look down on a busy downtown full of music venues. We plan each drop around the street in front of it: how wide it is, what hangs over it, and where the nearest outlet sits. Here is how that plays out across town.

Westmont and the west side

Westmont is a quiet, family neighborhood of about 5,000 people on the west side of the city. Most calls here are for birthdays, graduation parties, baby showers and home remodels. Driveways work well. A 2-station unit is 17 feet long with the tongue, so it slips into a standard driveway and leaves the garage open. If the party spills into the backyard, we set the steps on the side that faces your guests. Street parking on these blocks is tight on weekends, so we deliver early in the day, before the cars arrive.

Wilton Heights, Hacienda Park and the Edison district

Pomona’s residential historic districts hold more than 1,000 older homes, and many of them still have one bathroom and the original plumbing. A garden party or a kitchen gut job can overload that fast. Old pipes clog. Our private bathroom trailers take the pressure off the house. These streets have mature trees, so we check branch height before we arrive. Our trailers stand between 11 feet 4 inches and 12 feet 6 inches tall with the air unit on top, and we pick the spot that clears the canopy.

Arrow Highway, Palomares Park and the Pomona North station

The north end changed in September 2025, when the Metro A Line opened its Pomona North station. Trains now run all the way from Pomona to Long Beach, and the blocks near the station see new building work. Palomares Park sits on Arrow Highway with 17.9 acres of fields, right next to the 1854 Ygnacio Palomares Adobe. Softball tournaments, soccer days and adobe events all need more restrooms than the park has on a busy weekend.

Holt Avenue and the Village at Indian Hill

Holt Avenue is one of Pomona’s main business streets, lined with shops, car lots, restaurants and offices. The Village at Indian Hill, at 1460 East Holt, was once the Pomona Valley Center mall. Today it is a 39-acre education campus run by Pomona Unified. Store remodels, restaurant remodels and campus events along this corridor book our portable bathroom trailers for a day, a week or a full season.

Spadra and the south end

Spadra was founded in 1866 and was folded into Pomona in the 1960s. Its best-known building is the 1875 Phillips Mansion on Pomona Boulevard, the first brick home in the Pomona Valley. The south end also holds Ralph Welch Park and the stretch of State Route 71 that crews are turning into a full freeway. We stage trailers here for road work, park events and private gatherings at the historic site.

Diamond Ranch and the hills

Diamond Ranch High School opened in 1997 at the top of Diamond Ranch Road, and the streets around it climb. Sloped driveways need a trailer that can be leveled. Ours can. Ours carry leveling jacks, and we bring wood blocking for steep spots. On the smallest hillside lots we send a compact unit so the tow vehicle can turn around safely. Hillside homes here often host big family parties on the back patio, and a trailer at the top of the drive keeps guests off the stairs inside.

Washington Park and the east side

Washington Park on East Grand Avenue has three baseball fields, a softball field and two soccer fields. A youth tournament can put hundreds of families on the grass for a full day. One 5-station or two smaller units placed near the snack bar keep lines short between games. We place units on the pavement edge, not on the turf, so the fields stay in good shape for the next weekend.

Job Sites, Venues, Events and More: Portable Bathroom Trailers at Work in Pomona

Pomona builds, ships, teaches, heals and parties. Each kind of job uses our trailers a little differently, so here is what we see most, and what we bring for it. Whatever your project, call (818) 593-0069 and we will match the unit to the work.

Hospital and medical campus construction

Pomona Valley Hospital Medical Center has a long-range plan to grow its campus in phases, with new outpatient buildings, five-story patient towers, a larger emergency department and a 400-car parking structure, slated to wrap by 2030. Western University of Health Sciences and Casa Colina add more medical building in town. Contractors on these jobs keep a temporary bathroom trailer on site for months, serviced on a weekly schedule, so workers never walk into a clinic to use the restroom.

Freeway, rail and street projects

Caltrans and Metro are converting State Route 71 from an expressway into an eight-lane freeway between Interstate 10 and Mission Boulevard. The A Line extension that reached Pomona North in 2025 added track, platforms and parking work across four cities. Road and rail jobs move. The restrooms have to move with them. We set our units on gravel pads, relocate them as work zones shift, and pump them on a set route.

Warehouses, plants and shop yards

Pomona has a large share of distribution buildings, auto parts suppliers and machine shops near the 60, 71 and 10 freeways. Shifts change fast here. Plant shutdowns, restroom remodels, peak-season hiring and new tenant build-outs all call for extra stalls. A 9-station handles a big shift change, and a pair of 2-station units can sit at opposite ends of a long building.

School campuses

Pomona Unified operates dozens of campuses across the city, and summer is usually when restroom wings get rebuilt. Summer goes fast. When the building’s restrooms are closed, a trailer on the paved yard keeps summer school, sports camps and staff on schedule. Graduations, homecoming and Friday night games add guests the campus was never built for.

Concert halls and downtown nights

The Fox Theater Pomona opened in 1931 and was restored in 2009. Its Grand Hall holds 2,000 for a concert, and the building rents rooftop terraces and other rooms for private events. The Glass House on West Second Street has hosted all-ages shows since 1996. Crowds get big. Downtown also fills up for the Second Saturday ArtWalk, with its night market in Shaun Diamond Plaza, and for the December holiday parade down Second Street and Park Avenue. Outdoor beer gardens, load-in crews and street fairs all need restrooms that the venues cannot spare.

Historic sites and private parties

The Historical Society of Pomona Valley hosts summer dinners at the Palomares Adobe and concerts at the Phillips Mansion, and both sites book private events. Old buildings and small restrooms do not mix with 150 guests. A deluxe bathroom trailer parked out of sight lets the house stay the backdrop. The same goes for birthday dinners, rehearsal dinners, holiday parties and family reunions in big Pomona backyards.

Grand openings, car meets and fundraisers

Store openings on Holt and Mission, car club meets in big parking lots, church carnivals, 5K runs and school fundraisers all draw a crowd for a few hours. A single 5-station or a pair of 2-station units placed near the entrance handles most of them. For a run or a ride, we can set units at the start line and move one to the finish.

Emergencies, outages and repairs

Restrooms fail. Usually at the worst time. A sewer backup at a Garey Avenue restaurant on a Friday night is a common one. A water main break can close a school wing for a week, and a foothill fire can push families to a shelter that was never built for them. Those calls come to our 24/7 line, and we treat them as rush jobs. Tell us how many people need restrooms and for how long, and we will send the closest ready unit with a full stock of supplies.

Production basecamps

Pomona’s older shops, rail yards and Craftsman blocks show up in commercials, music videos and series. Call times are early. Every shoot in the city needs a film permit, and every basecamp needs restrooms for cast and crew. We drop before call time, keep the unit stocked between setups, and pull out after wrap.

Choosing the Right Station Count for a Pomona Bathroom Trailer Rental

Count the people, then count the hours. Drinks change the math. A four-hour party with no bar needs far fewer stalls than a ten-hour job site or a festival with drinks. Use the list below as a starting point, then call and we will check it against your plan. Every number here comes directly from our own specification sheets, so you can plan with confidence.

• 2-station: one women’s room and one men’s room, for about 150 guests or fewer. 105 gallons of fresh water, a 300-gallon waste tank and one 20 amp, 120 volt circuit. Best for driveways, small parties and short remodels.
• 3-station: two women’s rooms and one men’s room, for up to about 225 guests. 200 gallons of fresh water and a 400-gallon waste tank on one 20 amp circuit.
• 5-station: three stalls and two sinks on the women’s side, a stall, a urinal and a sink on the men’s side. Serves 150 to 450 guests, with 200 gallons of fresh water and a 520-gallon waste tank.
• 8-station private: eight unisex private stalls, each with a toilet, a urinal and a sink. Serves 400 to 600 guests, carries 400 gallons of fresh water and a 1,000-gallon waste tank, and draws power from two 20 amp circuits.
• 9-station: five stalls and two sinks for women, two stalls, two urinals and a sink for men. Built for 400 to 900 guests over a five-hour event, with a 750-gallon waste tank and two air units.
• ADA plus 2: one women’s room and one men’s room, plus an accessible unisex room with a self-contained ramp. Fits events up to about 200 guests or job sites of about 30 workers.
• ADA plus 6: four men’s rooms, two women’s rooms and one accessible unisex room, with a ramp built to federal and California standards. Handles events and job sites up to 300 people.

Big crowds call for the long units. The Pomona 9-station bathroom trailer is our highest-capacity unit and fits a ballfield lot or a warehouse yard. When privacy matters more than speed, the 8-station private bathroom trailer in the Pomona Valley gives every guest a full room with a lock. For a smaller crowd on a narrow lot, look at the 3-station portable bathroom trailer near Pomona.

Quick sizing for common Pomona jobs

• A backyard birthday or baby shower of about 80 guests: one 2-station.
• A garden wedding of 200 with an open bar: one 5-station, or a 3-station plus an accessible unit.
• A remodel or new build with about 30 workers: an ADA plus 2, serviced weekly.
• A full-day youth tournament on several fields: a 5-station near the snack bar plus an accessible unit by the parking lot.
• A street fair or concert lot with a few thousand people: several 9-station units in clusters, with an ADA plus 6 in each cluster.

Alcohol, heat and long hours all push these numbers up. A ten-hour shift with lunch on site uses a trailer harder than a four-hour reception, so we plan service around use, not the calendar.

Accessible units matter on public jobs and at events open to everyone. Both of our ADA models carry their own ramp and rails, so there is no lumber to build on site. Plan for the ramp’s footprint: the ADA plus 2 needs about 25 feet of length with the ramp down, and the ADA plus 6 needs about 31 feet.

Permits, Power and Placement for Temporary Bathroom Trailers in Pomona

The paperwork depends on where the trailer sits and why. Here is what applies in Pomona, in plain terms. It is simpler than it sounds. We are happy to talk it through on the phone before you file anything.

Parks, streets and public events

The City of Pomona’s Community Services team issues permits for special events and park use, and it publishes the special event application on its recreation facilities and permits page. Street closures and lot use downtown have their own forms. If your event needs restrooms, list the trailer count and the drop spot on the application. We will place the unit exactly where the permit says.

Private property and longer stays

For a temporary use on private land, such as a long construction job or a seasonal event, the city’s Planning Division handles Temporary Use Permits. Ask your contractor or the Planning counter whether your project needs one. We supply the trailer size, the footprint and the service schedule for your file.

Film and photo permits

Pomona requires a permit for all filming and still photography, from features to student projects. The city’s filming and photography permit page lists the forms: an application, a hold harmless agreement, an LA County Fire film permit, a parking plan and proof of insurance. Private property permits take about one business week. Put the restroom trailer on your parking plan so the location manager knows where it goes.

Food booths and health rules

If your event sells food, Los Angeles County Public Health sets the restroom math. Its community event organizer requirements call for one toilet for every 15 food workers within 200 feet of each food booth, kept separate from the public, plus a handwash sink for each of those toilets. Public restrooms need one handwash sink for every four toilets. Our units have sinks inside each room, which makes those counts easier to meet.

Power, ground and clearance

Most of our trailers need one or two standard 20 amp, 120 volt circuits within 100 feet. No outlet nearby? We can plan a quiet generator with you. Pick a firm, level spot that a truck and trailer can reach, away from fire lanes and driveways that must stay open, and remember to leave extra room for the steps, along with the full length of the ramp on an accessible unit.

Hot Summers, Santa Ana Winds and Winter Rain: Private Bathroom Trailers Through Pomona’s Year

Heat is the big one. Pomona sits inland, so it runs hotter than the coast. The hot season lasts from late June to late September, with average highs above 87 degrees, and August averages about 92 with heat waves well past 100. Every one of our trailers has air conditioning, and we switch it on early so the rooms are cool when the first guest walks in.

Wind comes next. Fall brings Santa Ana winds that pour through the Cajon Pass and across the valley. On wind days we drop the leveling jacks, chock the wheels, check every door latch and keep fuel and cords tucked away from dry brush. If a red flag warning shuts down an outdoor event, call us and we will move the pickup to fit your new plan.

Winter is short and wet. Rain turns lawns soft, so we lay boards under the jacks and set the steps on firm ground, and the heating system works as well as the air conditioning, which makes a real difference at a December evening party in a backyard. Spring fills up with graduations, weddings and ballfield tournaments, so book early for April through June.

A Pomona calendar for bathroom trailer planning

• January to March: rain, cool nights and steady construction. Plan for soft ground and keep the heat on.
• April to June: graduations, weddings, quinceañeras and weekend tournaments. This is our busiest stretch, so reserve early.
• July to September: the hottest months, summer school building projects and outdoor concerts. Air conditioning runs all day.
• October and November: Santa Ana winds, harvest parties and the Day of the Dead ArtWalk festival downtown.
• December: the downtown holiday parade, company parties and family gatherings, often on chilly evenings.

How Renting a Deluxe Bathroom Trailer in Pomona Works

Need a trailer today? Tell us when you call. Same-day delivery, rapid dispatch and emergency delivery are part of what we do, whether a pipe burst at a Holt Avenue restaurant or a crew of 40 just showed up early on a Diamond Ranch job.

Long-Term Rentals and Service Schedules for Temporary Bathroom Trailers in Pomona

Many of our Pomona rentals last weeks or months on hospital work, freeway projects, warehouse build-outs and school modernization, and a long rental is only as good as the service behind it. We set a fixed day for each visit, pump the waste tank, refill fresh water, restock every room and wipe down the fixtures. You get a clean trailer on the same day each week without having to call. Same day, every week.

How often we come depends on use, because a crew of 20 on a single shift may need only one visit a week, while a crew of 60 working long days, or a site that also hosts visitors, may need two or three. We watch tank levels on the first visits and adjust the schedule, so you are never paying for trips you do not need or running a trailer that is too full.

For big public events we can add an attendant who stays on site, keeps the rooms tidy and refills supplies between rushes. When the job ends, one call schedules pickup, and we leave the pad as clean as we found it.

Questions to Ask Before You Book a Mobile Bathroom Trailer in Pomona

Not every listing you find online belongs to a company that owns trailers. Some are brokers that take your deposit and farm the job out to whoever is free that day. Before you sign anything for a Pomona date, ask these questions. Our answers are below each one.

• Do you own the trailer you are sending? We do. Every unit in our fleet is ours, with no broker markup and no surprise subcontractor.
• Is it a real restroom or a dressed-up porta potty? Ours have flushing toilets, running water, sinks, mirrors, lights and climate control.
• Who answers the phone at night? Our own dispatch team, 24/7, at (818) 593-0069.
• What is in the quote? Delivery, setup, stocking, service and pickup, listed out. No hidden fees.
• Are you licensed and insured? Yes, and we can send a certificate of insurance to your venue, school district or general contractor.

If you already have a quote in hand, send it to us. We will look it over at no cost and tell you plainly how it compares.

Recent Portable Bathroom Trailer Jobs Around the Pomona Valley

A clinic remodel near the hospital campus

A general contractor renovating the restrooms of a busy medical office could not close the clinic for the six weeks the project required. We parked an ADA plus 2 beside the side entrance with its ramp facing the walkway, so patients and employees had an accessible room the entire time. Our technicians pumped and restocked it twice a week, early in the morning, before the waiting room filled up. When the new restrooms passed final inspection, we picked it up the same afternoon.

A garden reception at a historic home in Wilton Heights

The family expected 120 guests and had one small bathroom in a hundred-year-old house with original plumbing. We positioned a 3-station trailer on the side driveway, under a gap in the oak branches, and connected it to an outlet in the garage. It arrived the day before, the air conditioning was running by noon, and the house plumbing never felt a thing. Nobody waited in a hallway. We collected it the following morning, once the tent and the tables had been taken down.

A two-day shoot off Holt Avenue

A production company reserved a 9-station for basecamp in a closed commercial lot. We delivered it before the crew call, stocked it for 90 people, serviced it between shooting days and removed it an hour after wrap. Because the location manager included it on the permit parking plan, there were no surprises with the city, and the company reserved the same unit for another production a month later.

Pomona Bathroom Trailer Rental Questions, Answered

Can you set a trailer outside a downtown venue like the Fox Theater or the Glass House?

Yes, as long as the venue or a city permit gives us a legal spot. Downtown curbs are narrow and parking is metered, so we usually work from a side lot or a closed lane and send a shorter unit that fits without blocking traffic. Load-in times matter on show days, which is why we schedule our drop around the venue’s own trucks and stage crews.

How early should I book a trailer for a Pomona film shoot?

Call as soon as you file for the city film permit. Private property permits take about a business week, and the trailer location belongs on your parking plan, so knowing our unit size and overall length early saves your location manager a revision.

Can a bathroom trailer stay on a hospital or clinic job for several months?

Yes. Long-term rentals are common on medical construction, so we set a weekly or twice-weekly service day, keep a record of every visit, and swap in a larger unit if the number of workers grows during a busy phase of the project.

Do you deliver to work zones near the Pomona North station or along the 71?

We do. Road and rail projects usually want trailers on a gravel pad or in a staging yard, and we can relocate a unit as the work zone shifts from one segment to the next, so tell us your construction phasing when you call.

Will your trailers sit level on the sloped streets around Diamond Ranch?

Our trailers carry leveling jacks, and our drivers bring blocking for uneven ground. On very steep or narrow lots we send a compact unit, choose the flattest available spot near the house, and confirm the doors open and close properly before we leave.

What do you do on a Santa Ana wind day?

We lower the jacks, chock the wheels, secure the doors and steps, and keep power cords away from dry brush. If your event is postponed or canceled because of a wind or red flag warning, we reschedule the delivery or the pickup to match your new plan.

Does a youth tournament at Washington Park or Palomares Park need more than one trailer?

It depends on attendance and on how long the games run. A full day with several fields in use often calls for a 5-station near the snack bar and an accessible unit near the parking lot, so tell us the number of teams and we will recommend a layout.

Do you rent to schools during summer construction?

Yes. When a campus restroom wing is closed for renovation, a trailer on the paved yard keeps summer programs, sports camps and office staff on schedule, and we coordinate deliveries around district gate hours and service on a regular day each week.

How fast can you get a trailer to Pomona in an emergency?

Call (818) 593-0069 at any hour. We run 24/7 immediate dispatch and can often be there within 1 to 2 hours when pipes burst, septic systems fail or a building suddenly loses its restrooms.

Can I add a second trailer later if my guest list grows?

Yes. Start with the size that fits your current plan and call us if attendance goes up, because adding a unit is simple as long as the site has enough room and enough electrical capacity for it.

Do I need a water hookup at my Pomona site?

No. Each unit carries its own fresh water and waste tanks, so all you need is electricity, either an outlet within 100 feet or a portable generator that we can help you plan.

Can you place a trailer at a historic property without hurting the lawn or the driveway?

Yes. We lay plywood or rubber mats under the jacks and tires when the ground is soft, and we choose a path that avoids sprinkler heads, old pavers and low branches. Tell us about anything fragile on the property when you book.
