Self-Contained Shower Trailer Rentals, Set Up in Fontana
The Lavatory is the go-to team for private shower trailers in Fontana. We keep units staged close, so one can be on your pad, your yard or your staging area and ready the same day. Warehouse builds off Slover Avenue, fire assignments staging below the Cajon Pass, weekend events on Spring Street. Call us now or request a quote and we will hold the dates while you get your site squared away. We wrote about uniform laundry on tournament weekends for athletic directors.

Private hot showers for crews, camps, productions and emergency response.
Call (866) 509-6846 or request a quote and we will size the trailer to your Fontana dates.
The Lavatory is Fontana’s go-to source for private shower trailers
We own more than 250 units outright. That is the largest luxury trailer fleet in the Western U.S., and it is why a Fontana call gets a yes or a no on the spot instead of a callback. Thirty years in equipment rental, eight of them staging hot water in this market, and we are not a broker reselling somebody else’s trailer. Our crews have set units on graded dirt in the Jurupa Industrial Park, on asphalt at Fontana Park, and on the shoulder of a fire staging area at two in the morning. We handle portable shower trailer rentals across California, and Fontana is one of the yards we lean on hardest. Call for a hold or request a quote and we will confirm what fits your site.
The fleet is ours, start to finish
More than 250 units, owned outright, the largest luxury trailer fleet in the Western U.S. Ask whether something is free for the 12th and you get an answer, not a call to a third party.
Locking rooms with their own controls
Every shower is a private room with a door that locks and its own hot and cold valves. Smooth gel-coated fiberglass on the walls, ceiling and floor means it wipes down instead of holding a jobsite.
Service written into the deployment
Stocking, cleaning and pump-out on a cadence built around your schedule. On long Fontana jobs we will put an attendant on site rather than leaving it to the crew.
We route Fontana deliveries around the grade and the gate, not the map
The city drops from about 2,600 feet in the north to roughly 840 feet in the south, and the newer north-end tracts were laid out with narrow streets. A 35 foot rig that swings easily on Slover Avenue will not make a turn in Sierra Lakes. We look at the approach before we quote so nobody finds out at the gate.
“We had 60 guys on a pour week in July and no facilities anywhere near the pad. The eight room unit went in on temporary power and it was stocked before my first crew hit the gate every morning. Eleven weeks, zero complaints from me.”
“The accessible room is what sold me. We were turning people away before.”
“Called at nine at night during a wind week. The unit was on the lot before the first rotation came off the line, and they ran two pump-outs a day for the whole assignment without me asking twice. That is the review.”
The portable shower trailers that get booked again and again in Fontana
The companies that could rent anything still call us, because a bad shower at a base camp or a film set becomes the story of the whole job. The Lavatory has provided trailers 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 hot shower at the end of a long day is the one thing a crew remembers about the camp, so the trailer has to be stocked, heated and serviced every day of the job, not just the first one. That is how we run every unit in the fleet, and it is the same standard behind every Fontana booking, from a two-week jobsite to a festival campground.
Three decades in event and equipment rental, running the largest luxury trailer fleet in the Western U.S. Every unit ours, never a broker’s.
Jobsite portable shower trailers for the Speedway Commerce Center and Fontana’s big builds
In Fontana the 8-Station usually lands on an industrial pad in the south end or at a fire staging area, and a combo goes to a north-end school site or a park where 35 feet of trailer will not swing. We pick by head count, approach, and what the ground will hold after rain.

The old Auto Club Speedway is now the largest ground-up jobsite in the city. Hillwood bought the property in 2023 and is building Speedway Commerce Center, planned at roughly 6.6 million square feet of logistics space. Phase one already delivered about 1.8 million square feet across two buildings. By 2025, 433 of the 522 speedway acres had been sold off for industrial development. A site like that has no permanent worker facilities until the buildings are nearly done, and the trades cycling through it are grading crews, concrete crews, panel setters, roofers and electricians.
It is not the only one. Chaffey College is starting a 210.6 million dollar Fontana campus on 15 acres with four buildings. Fontana Unified broke ground on a north-end middle school at Citrus Avenue and Casa Grande Avenue for an August 2026 opening. The city is widening the Etiwanda Avenue intersection at Slover Avenue and Airport Drive starting in summer 2026 and running into summer 2027. ZM Trucks is building a 210,000 square foot zero-emission truck plant. Every one of those is months of dirty work on ground with no locker room.
What you find inside the trailer
Private rooms with a lockable door
Every shower is its own room with a door that locks, a bench and a hook, so a crew or a camp showers with real privacy instead of a curtain in a row.
Hot and cold water controls
A water heater and onboard tanks feed hot and cold controls in each room, with 1.5 GPM shower heads so the hot water lasts through a full shift of people.
Air conditioning and heat
Climate control in every trailer, so a shower in a July heat wave or a January storm response feels like the one at home.
One-piece gel-coated fiberglass
Walls, ceiling and floor are one molded fiberglass surface with no seams, which is why the rooms clean fast, stay clean and never smell like a locker room.
Runs with or without hookups
Fresh and waste tanks on board, a generator when the site has no power, and the option to tie into on-site septic on a long deployment.
Serviced, stocked and pumped
We deliver the trailer stocked and come back to pump, restock and clean on longer jobs, so day twelve looks like day one.
Then there is the heavy industry that never left. California Steel Industries still runs 430 acres of the old Kaiser mill site with about 115 acres under roof and roughly 1,000 people on the payroll. Mill outage work brings in refractory crews, scaffold crews and mechanical contractors who are not on the plant’s own roster and who finish a shift filthy. We have staged deluxe private units outside plant gates for exactly that, on a service schedule tied to the outage instead of a default weekly stop.
What we have learned here is that access kills more deliveries than head count does. The 8-Station is 35 feet with the tongue. A warehouse yard swallows it. A half-built school site with a single gate and a stacked lay-down area does not. We walk the approach before we quote, and we bring the build that actually fits the gate you have, not the one we wish you had. Call us and we will sort that out on the first pass.
We also handle San Bernardino shower trailer rentals.
We also handle luxury restroom trailers in Fontana.
Full specifications for every unit are on the 8-Station spec page and its four sister pages, or call and we will spec it to your Fontana head count.

The crew shower trailers we stage for Fontana, size by size
Five shower units cover everything from a single ADA-compliant room to a camp that showers two hundred people a day. Every one has hot water, private rooms and climate control. Tell us the head count, how long the job runs and what the site has for water and power, and we will size it.

8-Station Private Shower Trailer
Eight completely private shower rooms in a 29-foot box, built for crews, camps and relief sites of up to about 200 people a day. Hot and cold controls, 200-gallon fresh and 950-gallon waste tanks, an exterior four-sink hand wash bank under the roof line, and it can tie into on-site septic for long deployments. CAL FIRE approved for wildfire camp service, the spec incident teams ask for in every western state.

ADA + 2 Private Shower Trailer
Two standard private shower rooms plus one ADA room with a self-contained ramp, built to federal and California ADA requirements. The right unit when a site needs accessibility without giving up capacity, with 210 gallons of fresh water on board.

4-Station Shower, Restroom and Laundry Combo
Four private bathrooms, each with a toilet, sink, shower and power outlet, plus a washer and dryer in a separate room. A self-contained hygiene block for a crew of up to about 30 on a remote or long-term job.

2-Station Shower and Restroom Combo
Two private bathrooms with a toilet, sink and shower each, in a compact 11-foot box. The pick for a small crew, a ranch job or a production base that needs both functions in one footprint.

Single-Station ADA Shower and Restroom Combo
One fully accessible room: ADA china toilet with grab bars, roll-in shower with a seat and hand wand, ADA-height sink and vanity, and a ramp that deploys in minutes. It pairs with any other unit so every person on site is covered.
Bigger jobs run several trailers side by side, and long deployments get a service schedule instead of a one-time drop. If you are between sizes, we spec it to the head count rather than nudge you into more trailer than the job calls for.
Statewide coverage runs through our California shower trailer hub, with units sized to the head count.
Other Fontana jobs we stage private shower trailers for
Three kinds of work keep our Fontana trucks moving. Heavy construction and industrial jobs. Fire and emergency staging out of the Cajon Pass corridor. The events, camps and public programs that fill the city calendar from spring through fall.

Mill outage and plant turnaround work
California Steel Industries still runs the old Kaiser mill footprint with about 1,000 people. Turnaround crews come in from outside the plant and finish shifts filthy, and a unit outside the gate keeps that off the plant’s own facilities.

CityLink hygiene days and outreach
Fontana already runs scheduled shower days through CityLink with a mobile unit serving about 35 guests at a time. When a program wants to serve a hundred people instead, we bring a bigger portable setup and an accessible room on the same order.

Film and commercial production
The steel plant, the rail corridors, the Slover Avenue warehouse canyons and the Jurupa Hills all read as a specific place on camera. Basecamp hygiene for cast and crew is a line item on every one of those call sheets.

Warehouse yard electrification retrofits
Facilities working through their WAIRE obligations are installing charging infrastructure and converting yard tractors. That is electrical and civil work on an operating site, and those crews cannot use the building’s own facilities.

Agency and federal field work
We are SAM.gov registered, licensed and insured, part of an A plus BBB rated network with a 99.9 percent incident-free record. Accessible rooms and ADA ramps go on the same purchase order.
Glen Helen weekends and off-road events
The park campground north of town has been closed until further notice, so camping crowds at the amphitheater and the raceway arrive with nothing on the ground. We stage temporary hygiene for the whole weekend and service it daily.
What ties these together is that a hot shower changes how a long day ends. Because our units sit staged across the region instead of a couple of states away, getting a shower trailer to a Fontana site, even on a short-notice call, is an ordinary ask here, not a scramble.
Event and camp shower trailers for Fontana Park, Spring Street and Glen Helen

The Fontana calendar is busier than most cities this size. The Fontana Days Run turns 71 in 2026 and is set for Saturday June 6. The half marathon starts in the San Bernardino National Forest at about 3,800 feet and drops roughly 2,125 feet to a finish line in front of City Hall. USATF has called it the world’s fastest half marathon course since 1985. It started in 1955 with about 200 runners and now pulls more than 2,000. A finish line with vendors, exhibitors and food is a small village, and the build and strike crews are on site long before and after the runners.
Fontana Park on Summit Avenue covers 38 acres with a 14-lane competition pool, two nine meter waterslides, a skate and bike park and a dog park. The car show series takes over Spring Street between Juniper and Sierra five times a year from 5 to 8 in the evening. The Spring Street Night Market runs the same stretch. La Gran Fiesta fills Miller Amphitheater on Arrow Boulevard. The Mary Vagle Nature Center on Cypress Avenue hosts an overnight family Campout that runs from four in the afternoon to eight the next morning, which is a genuine overnight hygiene job on a site with nothing permanent.
Twenty minutes up the road, Glen Helen Regional Park covers 1,340 acres at the base of the Cajon Pass. The amphitheater there seats 65,000 and is the largest outdoor music venue in the country. Glen Helen Raceway runs four motocross tracks and has hosted off-road racing since 1985, and the Sheriff’s Rodeo is an annual fixture. The park campground has been closed until further notice, which pushes every camping need for those events onto temporary facilities brought in for the weekend.
Add the schools. Fontana Unified runs about 45 campuses and roughly 32,000 students, and weekend tournaments at Southridge Park and the high school complexes fill a whole Saturday. Our VIP finish matters at these jobs. A deluxe locking room with air conditioning and a real thermostat reads completely different from the plastic row by the parking lot, and that is the difference people remember.
What one shift without a private shower trailer costs sports camps in Fontana

Think about what a Fontana deployment actually costs to run. Wages, lodging, fuel, the schedule pressure, the people you are asking to work long days away from home. Then picture the end of that shift with nowhere to get clean. A shower is the one thing every person on site uses, and it is the detail they quietly judge the whole camp by.
A private shower trailer protects everything else you are spending. Crews sleep better and stay on the job, a production keeps cast and crew comfortable through a long schedule, and a relief site gives people back a piece of normal. Set against the cost of the deployment, it is a small line item that carries a lot of the morale, which is why the managers who have run a camp without one book the trailer first the next time.
Getting a portable shower trailer to Fontana, step by step
Booking should be the easy part of running a site. Four steps, a straight answer, and one team that owns the whole thing.
Tell us about the site
Share the dates, a rough head count and where the trailer will sit. That is enough for us to point you to the right unit and count.
We match the trailer and the hookups
We confirm whether the site has water and power or needs a generator and a supply, 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, heat the water and stock every room so it is ready before the first shift ends.
Use it, we handle service and pickup
The trailer holds up through the whole deployment while our line stays open. When you are done, we come back and take it away.

Our shower trailers, and the kinds of sites we set them up on. Base camps, jobsites, race weekends, productions and the relief sites where the trailer has to run for weeks.


How we deliver and run mobile shower units in Fontana

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 a water supply, fires the heater and stocks every room before the first person needs it. When the job wraps, we come back and haul it away.
On longer or higher-traffic bookings in Fontana, we pump and restock on a schedule, and an on-site attendant is available for camps and productions where the trailer runs all day. That always-clean standard is the difference between a shower people use once and one they are glad to use every night of the job.
Where self-contained shower units can sit on a Fontana site
Start with where the water goes. Sewage service in Fontana runs through the Inland Empire Utilities Agency, and shower water from a trailer is collected in the waste tank, then pumped by a licensed hauler or tied into an approved sewer connection. It does not go to the ground and it does not go to a gutter or a storm drain. On a job running past a few weeks we will price a septic tie-in instead of a pump schedule, because on the 8-Station a 950 gallon waste tank sets the cadence whether you plan for it or not.
Water supply is unusual here and it catches people. Five different providers serve parts of the city: Fontana Water Company, Cucamonga Valley Water District, Marygold Mutual Water, West Valley Water District, and the City of Rialto. Which meter or hydrant you are allowed to draw from depends on whose territory your parcel sits in, and the answer changes across a single street in places. We sort that out with you before delivery rather than after. If your job crosses the line into unincorporated ground like Bloomington, San Bernardino County Environmental Health handles holding tank approvals and annual operating permits instead of the city. Book Fontana and a nearby site together, and ask about private shower trailer rentals in Moreno Valley, CA for the second one.
Power and placement round it out. The 8-Station takes one 50 amp 220 volt circuit and the smaller combos take two 120 volt 20 amp circuits, so the question is a temporary drop, a tie to an existing panel, or a generator sized for continuous duty. Anything set in the public right of way or any lane closure goes through a City of Fontana encroachment permit, and park and facility use goes through the city’s event process. Commercial filming inside city limits needs a city film permit, while county parks and unincorporated areas go through the San Bernardino County Film Commission. We also run Ontario shower trailer rentals and cover the rest of the western Inland Empire, so a multi-city job stays on one order.

The accessibility and siting details we take care of
- ADA-compliant shower units with a ramp, roll-in shower, seat, hand wand, grab bars and an ADA-height sink.
- Guidance on where to place the trailer so it is easy to reach, easy to service and level.
- Water and power sorted before delivery, with a generator and a water supply staged when the site has neither.
- Licensed and insured on every unit we put on the road.
One thing we always say plainly: some sites, agencies and city permits have their own rules on placement, accessibility, greywater and temporary hygiene facilities. Tell us the site and we will help you plan around them, but confirm any permit requirements with the property or the agency as well.
Emergency temporary shower trailers for Cajon Pass fire camps and Fontana staging

Fontana sits on the valley floor right under the Cajon Pass, which is the funnel every Santa Ana wind event comes through. When a fire runs in that corridor, the flat ground with freeway access is down here. The Blue Cut Fire started August 16, 2016 in the pass and burned about 37,000 acres inside two days. It destroyed 105 homes and 213 other structures. Evacuation orders reached more than 34,000 homes and nearly 83,000 people across West Cajon Valley, Lytle Creek, Lone Pine Canyon and Swarthout Canyon. The base camps and the evacuation points went where the pavement was.
San Bernardino County Fire runs the Valley Division out of Fontana. Station 72 on San Bernardino Avenue is the division headquarters, with Station 71 on Arrow Boulevard, Station 73 on Banana Avenue, and Station 81 on Casa Grande Avenue covering the growing north end out of a 13,247 square foot house that opened in June 2024. We know those addresses because we have delivered to that side of the county at odd hours, and because a strike team rotating off the line at 0500 does not have two hours to wait.
Our 8-Station is CAL FIRE approved and it carries the exterior four sink hand wash bank, which matters at a camp where people are eating and rotating in the same footprint. Throughput is the number that counts at a base camp, not the daily total. Eight rooms with metered heads will move 40 to 50 people an hour once the line is organized. Dispatch runs around the clock. We also cover San Bernardino deluxe shower trailer rentals from the same yard, so a county-wide incident does not mean a second phone call.
One more thing about this region. Fontana is built on the Lytle Creek alluvial fan, and the Cucamonga Fault Zone runs along the foot of the San Gabriels just north of town with a modeled range of magnitude 6.0 to 7.0. Relief work after a quake is not a fire camp. It is longer, it is slower, and the accessible unit matters more because the population you are serving is not a fit young crew. We plan for both.
What planning shower trailers looks like for typical Fontana-area work

Site superintendent, tilt-up shell in the south industrial area
He had 60 people on a concrete week in late July with the nearest facilities a quarter mile off the pad. We put the 8-Station on temporary power at the back of the lay-down yard and set service for 5 a.m. so the rooms were stocked before the first pour crew arrived. He kept it eleven weeks and added the laundry combo in week three.
Battalion chief, staging area below the pass
Wind advisory week, strike teams rotating on a paved county lot with a water tender and nothing else. He needed 45 people through between 0500 and 0700. The eight room unit went in on a generator that night, and we ran two pump-outs a day for the length of the assignment rather than the usual one.
Program coordinator, community hygiene day
Their mobile unit handled about 35 guests and the line was longer than that every month. We brought the ADA + 2 alongside it so people using a wheelchair were not turned away, and the two units together cleared 90 people inside a four hour window. They book us now on a standing date.
Shower trailer rentals district by district across Fontana

We cover all 43 square miles of the city, from the industrial south end below the 10 up through the foothill tracts along the 210, and out into the ring of communities around it. That includes Rialto, Bloomington, Colton, Jurupa Valley and the western side toward Rancho Cucamonga shower trailer rentals and Ontario. Our service area reaches every state, but this page is a local hub with units staged nearby, which is how a same-day call gets answered with a truck instead of a timeline. Call dispatch or request a quote and we will tell you what we can put on the ground today.
We cover Fontana shower trailer rentals across California. Towns and job corridors we serve include Downtown Fontana, Central Fontana, North Fontana, South Fontana, Sierra Lakes, Summit Heights, Hunter’s Ridge, Southridge Village, Heritage Village, Walnut Village, Northgate, Rancho Fontana, California Landings, Morningstone, West End, Jurupa Industrial Park, Southwest Industrial Park, Rialto, Bloomington, Rancho Cucamonga, Ontario, Colton, Jurupa Valley, Devore.
Working beyond the city line? See our full shower trailer coverage across California.
Jurupa Industrial Park
Older industrial ground in the south end with steady tenant improvement and yard work. Most parcels here have temporary power available and the truck access is generous, so this is where the 8-Station goes without a second thought.
Slover Avenue corridor
The spine of south Fontana warehousing, and the street name attached to nearly every land use fight in the city. Construction here sits close to homes and to Jurupa Hills High School, so placement and service timing matter as much as the unit itself.
Sierra Lakes
Built on old olive orchard ground around the golf club, finished around 2006, with a specific plan capped at 2,035 homes. Events at the club and residential work are the jobs here, and the combo builds fit the streets.
Downtown Fontana
City Hall, the Lewis Library and the Steelworkers’ Auditorium sit in this core, and Spring Street carries the car show and the night market. Tight lots and public sightlines mean we place small and place early.
The Arboretum and Summit Heights
Active north-end growth with new school construction at Citrus and Casa Grande. Sites here are surrounded by occupied homes, so we schedule delivery and service outside the morning window.
Southridge Village
A planned community from the early 1980s in the Jurupa Hills, with Southridge Park and the Jack Bulik Center. Community events and park maintenance work drive the calls from this side of town.
Planned rentals are usually scheduled the same week, and we do our best to cover last-minute Fontana dates when a trailer is nearby.
Fontana reviews of our portable shower trailer service
“Our gate is tight and the neighbors are twenty feet away. They walked the approach before quoting, sent the small combo instead of the big rig, and scheduled service for after the school run. Somebody there actually thought about it.”
“Outage week is the worst week of my year. Having a clean private room outside the gate took one thing off the list.”
“Finish line build starts two days early and strike runs late. We had hot water for the whole crew both ends, and the deluxe units looked good enough that we did not have to hide them behind a fence.”
“Shot two nights in the hills with no services at all. Cast used the trailer without a single note, which on my jobs is the highest praise there is. Booked again three weeks later.”
“Our electrical retrofit crew could not use the building, period. They set a private unit in the back yard and serviced it daily. Easy.”
“We cleared about 90 people in four hours between their unit and ours. Before that we were doing 35 and sending the rest away. I do not know how else to say it.”
Answers on renting multi-station shower trailers around Fontana

How many shower stations do I need for a crew of 40 coming off one shift?
Depends entirely on the window. Forty people spread across nine hours is a small job. Forty people in the 45 minutes between a shift ending and a bus leaving is a throughput problem. Our heads are metered at 1.5 gallons a minute and a typical shower runs eight to ten minutes with changeover, so one room turns five or six people an hour. Eight rooms will move 40 to 50. Tell us the window, not just the head count, and we will size it.
Does a shower trailer need a water hookup on a Fontana job site?
Not necessarily. Every build we stage works self-contained or on hookups. The 8-Station holds 200 gallons of fresh water, which at 1.5 gallons a minute is a couple of hours of continuous single-head flow, so a busy deployment gets a hookup, scheduled water delivery, or both. On a graded pad with nothing on it we plan the water the same way we plan the waste, before the unit ships.
Where does the shower water go? Can it go down a storm drain?
No. It is collected in the unit’s waste tank and removed by a licensed hauler, or tied into an approved sewer connection. Sewage service in Fontana runs through the Inland Empire Utilities Agency. On the 8-Station the waste tank holds 950 gallons and that number sets the pump schedule, which we write into the job before delivery rather than working it out mid-week.
What power does the trailer need if my site has no permanent service?
The 8-Station draws from one 50 amp 220 volt circuit. The smaller combos take two 120 volt 20 amp circuits each. That means a temporary power drop, a tie to an existing panel, or a generator rated for continuous duty. Plenty of south Fontana warehouse sites already have temporary power staged for the trades, and tying in there is cheaper and quieter than running a generator all day.
Can a 35 foot trailer get into my site in north Fontana?
Sometimes yes, often no. The 8-Station is a 29 foot box and 35 feet with the tongue. Warehouse yards and industrial pads take it easily. The newer north-end tracts around Sierra Lakes and The Arboretum were laid out with narrow streets and tight radii, and a school site with one gate and a stacked lay-down area is worse. We look at the approach before we quote and send the build that fits.
Do you have an ADA accessible shower for a public program?
Yes, two ways. The ADA + 2 Private Shower Trailer gives you one ADA room plus two standard private rooms with a self-contained ramp, and it meets both federal ADA requirements and California’s accessibility code. The Single-Station ADA Shower and Restroom Combo covers an accessible spot on its own with a roll-in shower and grab bars. For a city or county program the accessible unit is usually the one that makes the whole thing work.
How fast can you get a unit out for a fire assignment or an emergency?
Dispatch runs 24 hours a day and we keep units staged near this market rather than routing everything from one central yard. On an incident below the Cajon Pass we have put an eight room unit on a staging lot the same night the call came in. Our 8-Station is CAL FIRE approved, and we hold units during red flag weeks instead of promising them twice.
Will the rooms be usable in an August heat wave?
That is the whole point of the build. August in Fontana averages a 96 degree high and the record here is 117. Every unit has air conditioning and heat with a smart thermostat, and the interiors are smooth gel-coated fiberglass rather than anything that holds heat or smell. A shower room that is hotter than the job site is not a shower room anybody uses.
What happens to the hot water when twenty people shower back to back?
Nothing, on a properly sized and fed unit. The metered heads keep the draw low enough that recovery stays ahead of the line, and every room has independent hot and cold controls so nobody is stealing temperature from the room next door. Where it goes wrong is an undersized water feed, which is why we settle the supply plan on the first call.
Do you serve unincorporated areas like Bloomington, or only inside Fontana city limits?
Both. We deliver across the whole western Inland Empire, including Rialto, Colton, Jurupa Valley and unincorporated ground like Bloomington and Devore. the practical result is paperwork, not distance. Inside the city you deal with Fontana for encroachment and event permits; on unincorporated parcels San Bernardino County Environmental Health handles holding tank approvals and annual operating permits.
How often does a unit get serviced on a long deployment?
As often as the job needs, which is the part people are surprised by. A standing weekly stop is fine on a light site. A fire camp or a 60 person pour week gets daily service and sometimes two pump-outs a day. Stocking and cleaning are part of what we do, not an add-on you chase, and on long Fontana jobs we will put an attendant on site.
Can we get showers and laundry from the same trailer?
Yes. The 4-Station Shower, Restroom and Laundry Combo has four private bathrooms, each with a toilet, a sink, a shower and an outlet, plus a washer and dryer in their own room. It holds 105 gallons fresh and suits crews up to about 30. On deployments running weeks rather than days, dirty clothes turn into half the problem, and that build solves both at once.

Deeper reading for site managers, camp coordinators and producers, from sizing a shower trailer to the head count to keeping hot water through a long deployment. Tap any guide to open it.
Sizing shower stations for a Fontana shift change, hour by hour
The first number almost everybody gives us is the head count. It is the least useful number on its own. Forty people is an easy job or a hard job depending entirely on when those forty people show up at the door.
Here is the math we actually use. Our heads are metered at 1.5 gallons a minute. A real shower, including getting in, getting clean and getting out, runs eight to ten minutes, and you need another minute or two for the room to turn over. Call it eleven minutes a person per room as a working number. That puts one private room at five to six people an hour. Eight rooms puts you at 40 to 50 an hour once a line is organized and somebody is keeping it moving.
What your Fontana site has to provide before a trailer arrives
Most delayed deliveries are not about the trailer. They are about the site not being ready for it, and almost all of that is preventable with one walk-through.
Ground first. The unit needs level, stable ground that will hold weight after it rains. Fontana takes about 14.77 inches a year and most of it lands between late November and early April, with February the wettest month at roughly 2.6 inches. A graded dirt pad in the Jurupa Industrial Park that carried a truck fine in October can be unusable in February. We will set on plates where we have to, but we need to know that before the truck rolls, not when it is already on your lot.
Where the water goes on a Fontana job, and who cares about it
This is the part of a rental nobody asks about until it becomes a problem, and in the Inland Empire it becomes a problem fast.
Shower water from a trailer is greywater. It carries soap, body oils, dirt and whatever the crew brought in on their skin from the job. It is collected in the unit’s waste tank. It is removed by a licensed hauler or sent into an approved sewer connection. It does not go onto the ground, into a gutter, into a storm drain or down a slope, and there is no version of a busy job where letting it find its own way is acceptable.
San Bernardino County Environmental Health, land use and wastewater
Planning hygiene for a Cajon Pass fire deployment or county staging
Fontana is not a fire city. It is a staging city, and that is a different set of problems.
The pass sits just north and east of town and it is the funnel for every wind event that runs into this valley. When something goes in that corridor, the incident is in the hills and the support is on the flat ground with the freeway access, which puts it here, in Rialto, or in San Bernardino.
