Guests remember the restroom: why The Lavatory leads on private restroom trailer rentals in Pomona
Guests forget the napkin color and the name of the band by Monday. They remember whether the restroom was clean, cool and easy to find, because it is the one place every single person at your event visits at least once. A long line or a warm plastic box quietly lowers how the whole day felt, even when everything else went right. That is the part of the event we own. Our trailers give each guest a real room with a flushing toilet, running water, a mirror and air conditioning, and our crew keeps them fresh from the first toast to the last dance. Call us or request a quote, and we will plan the one room every guest will judge you by. Around Pomona, the rest of the region is covered under restroom trailer rentals throughout the Inland Empire.
A direct fleet we own
We run a direct fleet, not a middleman or a broker, with more than 250 luxury trailers we own outright. The unit on your quote is the unit that shows up.
Real restrooms inside
China toilets, running water, mirrors and good light. Guests feel like they stepped into a nice hotel restroom.
Cool in valley heat
Pomona August highs average near 93 degrees. Every unit has air conditioning, and we start it before guests arrive.
We plan for freeways, fairgrounds and a historic downtown
Pomona sits where Interstate 10 and State Routes 57, 60 and 71 meet, which makes it easy to reach from our Southern California staging. Fairplex has wide lots and event roads, while the downtown Arts Colony has narrow one-way streets and angled parking. We plan the route and the backing path for each site before delivery day. Before the planning call, skim “4 Essential Event Planning Tips for Restroom Trailer Rentals.”

“The trailer arrived in good shape and everything worked the way it should for our students. Delivery was fast and organized, and the crew set it up so it was simple and safe for young people to use. We are glad to have them as a vendor for our Pomona campus.”

“Richard stayed with the trailers through our formal dinner and checked every room between speeches, always polite and quick to help a guest. The fixtures and finishes looked far nicer than anything we expected to find in a parking lot.”

“Our backyard in Phillips Ranch has a steep driveway, and the crew still backed the trailer in and leveled it without fuss. It made hosting so much simpler.”
The VIP restroom trailers that get booked again and again
The companies that could rent anything still call us for restrooms, because a cheap plastic unit at a launch party or a shareholder event ruins everything the day is meant to say. The Lavatory has provided luxury restrooms for names like Google, Tesla, BMW, Mercedes, eBay, and Target, for hospitality at Caesars Palace, and for pro sports including the Golden State Warriors, Oakland A’s, and Las Vegas Raiders.



The reason those bookings repeat is simple. A luxury restroom is the one vendor a guest uses and remembers, for better or worse, so the trailer has to be stocked, clean and working from the first guest to the last. That is how we run every unit in the fleet, and it is the same standard behind every Pomona booking, from a backyard engagement party to a festival gate.
Three decades in event and equipment rental, running the largest luxury restroom trailer fleet in the Western U.S. Every unit ours, never a broker’s.
Festival restroom trailer rentals for Fairplex, race weekends and park concerts
For a Pomona reception or company event with 150 to 400 guests, the 5-Station is the unit we recommend most. For fair and festival crowds or a long day with an open bar, we step up to the 9-Station or add a second trailer.

Pomona hosts some of the biggest crowds in Southern California. The Los Angeles County Fair at Fairplex drew 787,843 visitors in 2024 and runs Thursday through Sunday across most of May. The NHRA Winternationals and the season-ending Finals fill the Auto Club Raceway at Pomona from Friday qualifying through Sunday final rounds, and the new Knight Riders Cricket Ground on the Fairplex grounds opened in July 2026 as a future Olympic venue.
Permanent restrooms at a fairground or a race track are sized for an ordinary day, not a full house. Vendor rows, VIP tents, pit areas and parking lots on the far side of 543 acres all end up a long walk from the nearest building. Trailers placed where people actually gather cut the walk and the line at the same time.
Multi-day events live or die on service. We place clusters of trailers near food, stages and entrances, with an accessible unit in each cluster, and we pump and restock every night after the gates close. For a weekend race or a four week fair, we set that schedule before the first truck arrives, so every morning starts with fresh rooms.
Smaller events count too. The Arts Colony Art Walk on the second Saturday of each month, the Downtown Holiday Parade in December and summer concerts at Ganesha Park all draw crowds that run past the nearest public restroom. A compact trailer fits a closed street or a corner lot near the band shell.
The fittings inside a restroom trailer
Flushing china toilets
Real porcelain toilets with a foot flush, the same fixtures your guests use at home, not a chemical tank.
Running-water sinks
Stainless steel sinks with real running water, hand soap, and towels, fed by onboard water tanks so you are covered even without a hookup.
Climate control
Air conditioning for a summer afternoon and heat for a cold evening, so the trailer stays comfortable no matter the season.
Framed mirrors and lighting
Oversized framed vanity mirrors, warm interior lighting, and finished flooring that reads like a venue restroom, not a jobsite.
Fully stocked, always fresh
Premium toilet paper, towels, soap, and fragrance, restocked and pumped so the unit stays fresh from the first guest to the last.
Power and water handled
Onboard water tanks plus a generator when your site has no hookup, so the trailer runs anywhere from a vineyard to an open field.
Full specifications for every unit are on the 5-Station spec page and its four sister pages, or call and we will spec it to your Pomona guest count.
The full restroom trailer fleet is one page over; below is how we size a unit to a California guest count.
Five sizes of portable restroom trailers, and how to pick one for Pomona
Five sizes cover everything from a single ADA-compliant suite to a festival crowd. Every one has flushing china toilets, running water and climate control. Tell us your guest count and how long the event runs, and we will size it.

2-Station Restroom Trailer
One women’s suite and one men’s suite for up to about 150 guests, in a compact box that fits into a driveway or garden path. 105 gallons of fresh water, a 300-gallon waste tank and a single 20A/120V circuit make it the pick for backyard weddings and engagement parties.

3-Station Restroom Trailer
Two women’s suites and one men’s suite for up to about 225 guests, sized for the everyday mid-size gathering, from a milestone birthday to a company off-site. 200 gallons of fresh water, a 400-gallon waste tank, one 20A/120V circuit.

5-Station Restroom Trailer
Women’s side with 3 stalls and 2 sinks, men’s side with 1 stall, 1 urinal and 1 sink, built for 150 to 450 guests so a full reception never waits. 200 gallons of fresh water, a 520-gallon waste tank, one 20A/120V circuit within 100 feet.

9-Station Restroom Trailer
Women’s side with 5 stalls and 2 sinks, men’s side with 2 stalls, 2 urinals and 1 sink, sized for 400 to 900 guests so hundreds of people can move through the line at once. Two AC units, two 20A/120V circuits, a 750-gallon waste tank.

ADA + 2 Restroom Trailer
One women’s suite, one men’s suite and one ADA unisex suite with a self-contained ramp, built to federal and California ADA requirements. Sized for events up to about 200 guests or job sites up to about 30 crew, with 210 gallons of fresh water on board.
An 8-Station Private Stall Deluxe and an ADA + 6 configuration are also in the fleet for big productions and larger guest counts. If you are between sizes, we spec it to your guest count rather than nudge you into more trailer than the day calls for.
For events beyond this city, our California restroom trailer service area lists every region we deliver to.
How booking a bathroom trailer works in Pomona
Booking should be the easy part of planning an event. Four steps, a straight answer, and one team that owns the whole thing.
Tell us about the event
Share your date, your rough guest count, and the venue. That is enough for us to point you to the right size trailer.
We match the trailer and site
We pair you with a unit, confirm whether the site has water and power or needs a generator, and pin the exact spot so delivery is one clean trip.
Delivery and setup
We arrive on your schedule, level and set the trailer, connect it, and stock it so it is ready and fresh before the first guest.
Enjoy it, we handle pickup
The trailer holds up through your whole event while our line stays open. When you are done, we come back and take it away.
VIP restroom trailer rentals for company events, formal dinners and campus gatherings in Pomona

Pomona hosts a steady stream of corporate and institutional events. The Sheraton Fairplex conference center and its Exposition Hall hold events in the thousands, the DoubleTree by Hilton Pomona ballroom seats several hundred, and the restored 1931 Fox Theater downtown books concerts, formal dinners and private parties. Cal Poly Pomona, Western University of Health Sciences and Pomona Valley Hospital Medical Center add graduation parties, donor events and open houses all year.
Outdoor portions of those events are where restrooms fall short. A tent on a campus lawn can sit a long way from the nearest indoor restroom. A VIP restroom trailer placed beside the tent keeps guests in the event and gives sponsors the kind of room they expect.
For formal dinners and launches we often place an 8-Station Private Stall Deluxe, with eight private rooms that each open to the outside. For crews, caterers and staff working long hours behind the scenes, a 2-Station or 3-Station out of sight keeps the back of house moving.
Load-in windows at hotels and campuses are tight. We confirm our delivery time with your event manager, set the trailer before the rentals and catering arrive, and remove it after load-out. Planners with events across the Inland Empire can also use our Rancho Cucamonga restroom trailer rentals.
Our luxury restroom trailers, inside and out in Pomona
Our restroom trailers, and the kinds of events we set them up for. Backyard weddings, vineyard receptions, corporate lots, film sets, and the festival gates where the lines have to move.





Set, stocked and serviced: restroom trailers in Pomona

We handle the whole thing, not just the drop-off. Our team delivers the trailer, levels and sets it, connects water and power or stages a generator, and stocks it before your first guest arrives. When the event wraps, we come back and haul it away. You never touch the logistics. That part is on us.
For longer or higher-traffic bookings in Pomona, we offer an on-site attendant who keeps the trailer stocked and spotless through the event, and we pump and refresh the unit so it holds up from the first guest to the last. That always-fresh standard is the difference between a restroom guests use once and one they are glad to use all night.
Commencements, quinceaneras and remodels: more places our portable restroom trailers go
Three kinds of events fill our Pomona calendar. Fair and festival crowds at Fairplex and in the parks need restrooms in volume. Couples at historic estates and backyards want restrooms that match the day. Company and campus hosts want private rooms that fit a formal dinner or a launch. Each one plans differently, and we plan each one with you.

Graduations and commencements
Commencement weekends on campus bring families by the thousands. We place trailers near seating and parking so guests do not miss the ceremony waiting in line.

Quinceaneras and family parties
Big family celebrations at home or in a park picnic shelter need more than one bathroom. A 3-Station or 5-Station keeps the party going.

Office and store remodels
When a remodel takes a building’s restrooms offline, a trailer by the back door keeps staff at work until the plumbing is back.

Church festivals and outdoor masses
Parish festivals and outdoor services draw crowds larger than any church restroom. We size a unit to the crowd and set it near the courtyard.
Farmers markets and street fairs
Weekly markets and downtown events need restrooms for vendors and visitors. A compact trailer fits a parking lot corner.
Film and photo shoots
Crews shooting on location around the valley want a clean restroom near base camp. We match the unit to the crew and move with the schedule.
What ties these together is the guest experience. Nobody remembers a restroom that worked, but everybody remembers one that did not. Because our units sit staged across the region instead of a couple counties away, getting a luxury trailer to a Pomona date, even a last-minute one, is an ordinary ask here, not a scramble.
Where luxury restroom trailers can sit on a Pomona site
A trailer on your own driveway or private lot for a short event usually needs no city permit, though some HOAs have their own rules about trailers. Events in city parks, on public streets or open to the public need approval from the City of Pomona. The Community Services Division at the Palomares Park Community Center handles park picnic shelter and band shell rentals and the permits for special events. We run Pomona and the surrounding towns together, including portable bathroom trailer rentals in Corona, CA.
Los Angeles County Public Health, through its Environmental Health division, sets requirements for community events with food, including enough restrooms and hand washing stations for the crowd. A trailer with running water and hand sinks helps an event meet those checks. We handle all pumping and waste disposal ourselves, so you never hire a separate hauler.
Accessibility is part of every public event plan. Under the 2010 ADA Standards, at least 5 percent of portable toilets at a temporary event must be accessible, and when only one is provided, it must be the accessible one. Our ADA + 2 covers that need in one trailer. For planners working across the Inland Empire, our Fontana restroom trailer rentals follow the same process.

Accessibility and pad prep, handled
- ADA-accessible units with a self-contained ramp, wide door, grab bars, and turning room.
- Guidance on where to place the trailer so it is easy to reach and easy to service.
- Water and power sorted before delivery, with a generator staged when the site has no hookup.
- Licensed and insured on every unit we put on the road.
One thing we always say plainly: some venues and city permits have their own rules on placement, accessibility, and event restrooms. Tell us your venue and we will help you plan around them, but confirm any permit requirements with the venue or the city as well.
Deluxe bathroom trailers for estate, garden and backyard receptions around Pomona

Many of the loveliest wedding settings in Pomona were never built as banquet halls. Kellogg House at Cal Poly Pomona is a 1926 estate whose garden terraces hold receptions of up to 200 guests, with only a small indoor room nearby. The Ygnacio Palomares Adobe is a museum ranch house from the 1850s. The city rents picnic shelters at Ganesha Park and Palomares Park, and the historic Ganesha Band Shell, for weddings, quinceaneras and family celebrations.
Those settings photograph beautifully, and their restrooms are sized for a quiet weekday. When 200 guests arrive, two small rooms become a line by the second hour. A deluxe bathroom trailer set a short walk from the dance floor solves that without anyone noticing it arrived.
We suggest the 5-Station for most receptions of 150 to 300 guests and the 8-Station Private Stall Deluxe when every guest should have a private room with its own sink. Backyards in Phillips Ranch and north Pomona often sit on slopes, so we look at photos first, choose a unit length that fits the driveway, and put boards under the jacks on soft lawn.
Pomona summers run hot, with August highs averaging near 93 degrees. We turn on the air conditioning well before guests arrive, so the rooms feel cool when the first guest walks in after the ceremony.
What a VIP restroom trailer saves a Pomona event

Think about what a Pomona event actually costs to put on. The venue, the catering, the flowers, the photographer, the hours of planning. Then picture a guest walking out of a hot plastic box in the middle of all of it. Nobody plans for that. The restroom is the one vendor every single guest uses, often more than once, and it is the detail they quietly judge the whole event by.
A luxury restroom trailer protects everything else you spent on. It reads like an extension of the venue, holds up through a full day of guests, and gives people one less thing to remember for the wrong reason. Set against the total cost of the day, it is a small line item that quietly carries a lot of the impression, which is exactly why the hosts who have been burned once book the trailer first the next time.
Three common Pomona setups for restroom trailers

Typical setup: a race weekend at the race track
When a three day race fills the grounds, we place clusters of trailers near the grandstands, the pits and the vendor midway, each with an accessible unit. We pump and restock every night after the last run.
Typical setup: a garden reception at a historic estate
When a couple hosts 200 guests on garden terraces, we look for a firm, level spot a short walk from the tent and out of the photos. A 5-Station or an 8-Station Private Stall goes there, and we start the air early on a warm afternoon.
Typical setup: a formal dinner on a campus lawn
When a university hosts a donor dinner under a tent, we place a private stall trailer beside the tent and a smaller unit behind the catering area for staff.

Planning an event beyond the city line? See our full restroom trailer coverage across California.
Downtown and the Arts Colony
Galleries, the Fox Theater and the monthly Art Walk. Narrow streets and tight parking mean shorter trailers and careful delivery timing.
Fairplex and the south side
Home to the fairgrounds and the conference hotels. Wide lots here handle our largest trailers and multi-trailer clusters.
Phillips Ranch
Hillside homes in the southwest with sloped yards. Backyard receptions here need a firm, level spot and a clear path for the truck.
North Pomona and Ganesha Park
Older neighborhoods around Ganesha Park and its band shell. Park picnic shelter parties and family events are common.
Cal Poly Pomona and Kellogg House
A large campus on the west side with a historic estate that hosts weddings. Campus events need coordination with university staff.
Lincoln Park and central Pomona
Historic homes and tree-lined streets near downtown. Backyard parties and church events fill the weekends.
Planned rentals are usually scheduled the same week, and we do our best to cover last-minute Pomona dates when a trailer is nearby.
What Lavatory customers say about our event restroom trailers

“Once you step inside, you would never guess you are in a trailer. It was clean, comfortable and relaxing, the kind of restroom that makes an outdoor party in Pomona feel a lot more civilized.”

“Some events call for more than a row of porta potties, and this is the company for those. The Lavatory gave our guests clean, spacious restrooms, and I recommend them without reservation.”

“Sal treats every job like it matters, whether it is a big fair setup or a small party. He was respectful, on schedule and handled the whole restroom trailer service for our Pomona event from start to finish.”

“We rented for a quinceanera at our house and the team did everything we asked, right down to where the steps faced. Guests kept telling us how nice the bathrooms were.”

“Setup was quick and professional, and the restroom trailer stayed spotless through our party. We were very happy with the rental and would book it for our next celebration.”

“They arrived on time and handled everything with real professionalism. These are the nicest restroom rentals I have seen at any event I have attended.”
What venue managers ask about bathroom trailers in Pomona

Do I need to book early for a spring or fall wedding in Pomona?
Yes. Saturdays from April through October book up first, and fair season in May keeps many trailers busy across the region. Reserve as soon as you have a date and a rough guest count. We can change the size later if your list grows.
Will you rent a restroom trailer for a long construction or remodel project?
Yes. We rent by the week or by the month for remodels, campus projects and job sites. We set a pumping and restocking schedule that fits the crew, and the trailer stays until the work is done.
Can you provide an attendant to keep the trailer clean during the event?
Yes. For large events we can add an attendant who keeps the rooms tidy and the supplies full while guests are there. For most receptions, a trailer stocked before guests arrive is all you need.
Is the waste tank big enough for a multi-day fair or race weekend?
Not for the whole event, and it does not need to be. We pump and restock each night after the gates close, so the tanks start every morning empty and the rooms start fresh.
Where does the cost of a restroom trailer rental come from?
Five things drive the quote: the trailer size, the number of days, the distance from our staging, how often it needs service, and whether you need a generator or an attendant. The quote shows each piece so you can compare it fairly.
What permits do I need for a restroom trailer at a Pomona park or street event?
On private property for a short event, usually none. In a city park or on a public street, you need approval from the City of Pomona through its Community Services Division, and events with food follow Los Angeles County Public Health rules. We place the trailer wherever your permit allows.
When do you deliver and pick up the trailer?
We usually deliver the day before the event, level and stock the trailer, and turn on the air or heat early. We pick it up the day after, or right after load-out for events on tight venue schedules.
How many trailers do I need for a festival crowd?
It depends on the crowd, the hours and whether alcohol is served. For a few thousand guests over a full day, plan on several large trailers placed in clusters near food and stages, with an accessible unit in each cluster. We size it with you.
Will a trailer fit at a downtown Arts Colony venue?
Usually, with the right unit. Downtown streets are narrow with angled parking, so we look at the spot first and often send a shorter 2-Station or 3-Station that fits a side lot or a closed street.
Does the trailer need water and power at a park picnic shelter?
It does not need water, since every unit carries its own fresh water tank. Most units need one standard outlet within 100 feet, and if the picnic shelter has none, we can plan a quiet generator with you.
How many guests can each trailer size handle?
For an event of about four to five hours, the 2-Station serves up to about 150 guests, the 3-Station up to about 225, the 5-Station 150 to 450, the 8-Station Private Stall 400 to 600, and the 9-Station 400 to 900. The ADA + 2 covers events up to about 200 guests or crews up to about 30. Longer events and open bars push each number down.
Is The Lavatory the company that actually owns the trailer?
Yes. We are a direct fleet, not a reseller, and we own more than 250 luxury trailers outright. The crew that quotes your event is the crew that delivers, services and picks up the trailer, with a 24/7 phone line the whole time.
Pomona planning guides for mobile restroom trailers

Deeper reading for hosts and planners, from sizing a trailer to your guest count to keeping guests comfortable through a long event. Tap any guide to open it.
Restroom planning for a fair, race or festival at Fairplex
Big events at Fairplex draw big crowds, and restroom lines are one of the first things guests remember. The Los Angeles County Fair averaged about 49,000 visitors on each open day in 2024, and race weekends at the race track fill the grounds from Friday to Sunday.
Size for the peak, not the average. The biggest rush comes after a headline act, between rounds, or when a concert lets out. Plan enough stations to keep lines short at that moment, and add trailers when alcohol is served.
Choosing a restroom trailer spot at an estate or garden wedding
Historic estates and gardens are beautiful places to marry, and they are tricky places to park a trailer. Garden terraces, old trees and sprinkler lines all shape where a unit can go.
Look for firm, level ground first. A paved drive or a gravel pad is ideal. Lawn works when it is dry, and we put boards under the jacks when it is soft.
Hookups or onboard tanks: how water and power work at a Pomona park or backyard
People often ask whether they need a water hookup for a restroom trailer. They do not. Every trailer carries its own fresh water tank and a large waste tank, so it can run in a park, a backyard or a parking lot.
Hookups help on long rentals. If a hose bib is nearby, we can connect it so the fresh tank stays full on a job that runs for weeks.
How many accessible restrooms does a public event need?
Accessibility is part of every public event plan, and it is easy to get right when you plan it early. Guests with mobility needs, older relatives and parents with strollers all benefit from an accessible room.
The 2010 ADA Standards set a simple floor: at least 5 percent of portable toilets at a temporary event must be accessible, and if only one unit is provided, it must be the accessible one.
