Bathroom Trailer Rentals Serving the Fresno area

Mavirus Group rents private portable restroom trailers to Fresno public works crews, farm employers and school districts across the San Joaquin Valley. Each bathroom trailer has flushing toilets, running water sinks and air conditioning built for a Fresno July, and our own crew delivers and services it on a fixed schedule. A sewer crew downtown and a grape harvest crew near Selma can both be covered from one call. Call us to plan your site, or request a quote and we'll size the order to your crew.

Public Works, Farms and Schools

Mavirus Group supplies restroom trailer rentals for Fresno public works, farms and schools

Fresno is in the middle of several long jobs at once. The city is tearing up downtown streets to replace water and sewer lines, the high-speed rail line is taking shape through the valley and old school buildings are being rebuilt one campus at a time. Around all of that, the county's farms put large crews in the field from May into fall. Each of those jobs puts people far from a working restroom. Mavirus Group brings private restroom trailers with air conditioning and running water, and we service them on a schedule you approve. Our SAM.gov registration is current, and our license and insurance are on file for public buyers. Call us with your crew size and site, or request a quote and we'll send a written plan.

What customers say

R
Rafael M.harvest crew supervisor, vineyard operation, south Fresno County
★★★★★

We moved blocks every couple of days during grape season. They towed the units right behind us each time, and the crew never had to walk back to the shop.

D
Donna K.construction manager, city utility project, downtown Fresno
★★★★★

Our crews had no plumbing on the block for months. The small unit fit inside our lane closure and moved with us every time we shifted down the street.

H
Hector R.facilities director, school district, Fresno
★★★★★

Our oldest campus lost its restroom wing to the remodel for a full semester. The ADA trailer was clean every morning, and teachers stopped fielding complaints within a week.

Our Restroom Trailer Fleet

The private restroom trailers we set up at Fresno jobsites, farms and campuses

The 2-Station trailer is our most common unit in the valley. It holds one women's room and one men's room, each with a flushing toilet and a running water sink. It carries 105 gallons of fresh water and needs only one 20 amp, 120 volt circuit, which a small generator can supply at the edge of a field. Its size makes it easy to tow down a farm road or park in a single lane on a torn-up street.

Big sites get the 8-Station Private Stall Deluxe unit. Eight private stalls each have a toilet, a urinal and a sink, and the trailer carries 400 gallons of fresh water with a 1,000 gallon waste tank. Two air conditioners hold the inside at a workable temperature on days when Fresno tops 105 degrees. It fits a rail staging yard or a school parking lot where a crowd of workers or students needs restrooms all day.

For schools and public sites, the ADA +6 trailer adds an accessible room with a self-contained ramp built to federal and California standards, next to six standard stations. Every unit we rent runs on its own tanks where there is no sewer, and each one connects to site water and power when it's available. Our techs handle pumping, cleaning and restocking. In summer, we add visits so no unit runs short during the hottest weeks. For a downtown street crew or a harvest crew that moves each week, we usually start with 2-Station units. School sites and large rail yards tend to need an 8-Station unit plus an ADA +6.

Fresno Restroom Work

Where our portable restroom trailers work across the Fresno area

Restroom trailer work around Fresno falls into three main groups. Public works and public construction lead the list, from the downtown infrastructure rebuild to the high-speed rail station. Agriculture comes next, with harvest crews and packinghouse yards across the county. Schools round it out, led by Fresno Unified's long list of aging campuses. Each group has its own season and its own service rhythm.

Downtown Rebuild and High-Speed Rail

Restroom trailers for Fresno street rebuilds and high-speed rail construction

The City of Fresno is rebuilding downtown one block at a time. Crews are replacing water and sewer lines, then rebuilding the streets and sidewalks over them. While a block is open, nobody on it has working plumbing. The crews on those blocks can go months without a restroom close by.

California High-Speed Rail adds a second large job. Work spans the valley through Madera, Fresno, Kings, Tulare and Kern counties. More than 80 miles of guideway and 61 major structures are finished, and track installation is moving forward in 2026. The downtown Fresno station is under construction next to Chinatown, and peak-day workforce on the program has reached about 1,700 people.

Title 8 Section 1526 sets the rules for toilets on these sites. Facilities must be clean, working, private and stocked, and nonwater-carriage toilets are allowed where a sewer connection or adequate water isn't practical. A torn-up downtown block or a rail segment out in the fields fits that description, and a self-contained trailer is built for it. City crews and their contractors can read more about public works restroom trailers for Fresno street rebuilds.

We match units to how the work moves. Street crews get 2-Station units that shift a block at a time, with the moves written into the order. Rail staging yards get 8-Station units that stay put for the whole phase. Send us the block schedule or the segment map, and we'll lay out the units and the service route.

Farm Crews and Packinghouses

Portable restroom trailers for Fresno County harvest crews and packinghouse yards

Fresno County set a record for gross farm value in 2024. It became the first county in American history to clear that mark, led by almonds, with grapes and pistachios close behind. That output depends on large outdoor crews who spend long days in orchards and vineyards.

The harvest moves across the county on a set calendar. Stone fruit starts in mid-May around Sanger, Reedley and Parlier. Grapes follow in mid-July in the belt around Selma, Fowler and Kingsburg, and almond shaking runs in August. September brings the raisin sprint, when crews race to get fruit onto trays before the cutoff.

Farm crews move from block to block, sometimes every day or two. A restroom at the ranch shop doesn't help a crew two miles down the road. We place 2-Station units at the end of the rows being worked and move them along with the crew. Packinghouse yards and processing sites get larger units that stay in place for the season.

Water and restrooms go together in this heat. Section 3395 requires cool water close to the work and names agriculture directly. Growers often add Fresno water station trailer rentals for harvest crews next to each restroom unit, so both move with the crew. Send us your harvest calendar, and we'll plan units for each crop window.

School Modernization

Restroom trailers for Fresno Unified and Clovis-area school construction

Fresno Unified runs 106 schools with about 73,000 students. More than two-thirds of its schools were built before 1970. Measure H, a local bond, pays to repair and modernize those aging campuses, and many projects touch restrooms and plumbing directly.

When a school's restroom wing closes for work, students still need restrooms during the day. Portable booths are a poor fit for young children and for students with disabilities. A trailer with private rooms, running water and lighting keeps the campus open in a way parents accept.

Clovis, on Fresno's northeast edge, is one of the faster-growing cities in California. New subdivisions bring new schools, and crews building them need restrooms long before the permanent ones are finished. We serve both kinds of sites, occupied campuses and new builds.

We schedule around the school day. Deliveries and pump-outs happen before the first bell, after dismissal or on weekends. An ADA +6 unit covers accessible needs. Districts planning several campuses at once can read about school campus restroom trailers for Fresno Unified projects. Send us the project list, and we'll quote each campus.

Other Fresno-area sites that rent our bathroom trailers

West side solar construction

The Darden Clean Energy Project, approved in June 2025, covers 9,500 acres of retired farmland on the county's west side. It is expected to put more than 2,000 workers on remote ground for up to three years.

Highway 99 interchange projects

Caltrans is rebuilding interchanges along Highway 99 as part of a long upgrade of the corridor. Projects near Visalia run from 2025 to 2027, with more to follow. Crews work beside a busy freeway far from any building.

Flood shelters in the Tulare Lake basin

In 2023, levee breaches led Tulare County to order evacuations west of Highway 43. About 1,000 people in Allensworth and Alpaugh were affected. Shelters in small towns ran short on restrooms fast.

Sierra fire staging along Highway 168

Fresno is the staging city for fires in the central Sierra. The 2020 Creek Fire burned 379,895 acres in Fresno and Madera counties. Staging areas and camps on the way to Shaver Lake need restrooms for large crews.

Fairgrounds during the Big Fresno Fair

The Big Fresno Fair brings more than 600,000 people to the county fairgrounds every October. Vendor and staff areas behind the scenes can use a private trailer of their own.

Fresno Heat

How Fresno heat shapes restroom trailer service in the valley

Fresno sits in a flat bowl with almost no marine cooling. July averages a high near 99.7 degrees. On July 7, 2024, the city hit 114, and that July became the hottest month on record, with 19 days at 105 or above. In 2021, the city logged 69 days at 100 degrees or more.

The heat season is also starting earlier. In March 2026, Fresno hit 93 degrees and broke a monthly record that had stood since 2015. The all-time high is 115 degrees, set on July 8, 1905, so extreme heat is nothing new here. The city opens cooling centers when the forecast reaches 105.

Heat changes how a restroom trailer runs. Crews drink more water, so they use the restroom more, and tanks fill faster. We tighten the service calendar from June through September. Every unit's air conditioning keeps the inside workable, and we park units in shade or with their doors away from the afternoon sun when the site allows it.

Customer Stories

How a typical Fresno restroom trailer job is set up

How we would set up restrooms for a grape harvest crew near Selma

For a 60-person crew moving through vineyard blocks, we'd place two 2-Station units at the end of the rows being picked. Each time the crew changes blocks, we'd tow the units to the next ones. Pump-outs would run every other day during the heat.

How we would set up restrooms for a downtown sewer replacement crew

We'd place a 2-Station unit in the closed lane at the end of the block, inside the traffic control zone. When the crew moves to the next block, the unit moves too. Service would happen early in the morning before traffic builds.

How we would set up restrooms for a Fresno Unified elementary modernization

For a campus with its main restroom wing closed, we'd set an ADA +6 near the playground gate where staff can see it. Service would run after dismissal each day. The unit would stay until the new restrooms pass inspection.

California Sanitation and Heat Rules

Cal/OSHA rules our Fresno restroom trailers are set up to meet

Title 8 Section 1526 governs toilets on construction sites with more than one worker. They must be clean, in good working order, private and stocked with toilet paper. Where a site has no sanitary sewer or adequate water, the rule allows nonwater-carriage toilets. That fits the rail alignment and the downtown rebuild. It also fits the west side solar site, where long stretches of ground have no plumbing at all.

Section 3366 covers washing facilities in general industry. It applies at packinghouse yards and processing plants in the Sanger and Reedley stone fruit belt. Workers need running water and cleansing agents within reasonable reach. Single-user toilets may be marked all-gender under Health and Safety Code Section 118600, and Cal/OSHA still enforces the total number of fixtures.

Section 3395 is the heat rule, and it names agriculture and construction directly. Employers must provide at least a quart of cool water per worker per hour, close to the work. Shade is required above 80 degrees, and high-heat procedures start at 95, which is a normal summer day in Fresno. Farm employers also add a cool-down break of at least ten minutes every two hours on long shifts. A restroom near that break area makes it easier for crews to keep drinking water.

FAQ

Frequently asked questions

Can a restroom trailer follow a harvest crew from block to block?
Yes. We place 2-Station units at the end of the rows being worked and tow them to the next block when the crew moves. Tell us the harvest calendar and the ranch roads, and we'll plan each move.
How often do you service units in a Fresno summer?
More often than in cooler months. Crews drink more water in the heat and use restrooms more. From June through September, we tighten the service calendar by default, and we add visits if a unit fills faster than planned.
Does Cal/OSHA allow restroom trailers on the downtown rebuild and rail sites?
Yes. Section 1526 permits nonwater-carriage toilets when a site can't tie into a sewer or lacks an adequate water supply. Our units carry their own tanks, which fits torn-up streets and rail segments in open fields.
Can a restroom trailer fit inside a lane closure on a city street?
Usually. The 2-Station unit is short and narrow enough to sit inside most single-lane closures. We place it inside your traffic control zone and away from the pedestrian path.
What does a restroom trailer need for power at the edge of a field?
The 2-Station unit runs on one 20 amp, 120 volt circuit, which a small generator can supply. The 8-Station unit and the ADA +6 each need two. Tell us what's available at the site, and we'll plan the power.
Can you provide restrooms for a school while its restroom wing is closed?
Yes. An ADA +6 trailer gives students an accessible room and six standard stations. We deliver and service outside school hours, and we place the unit where staff can supervise it.
Do you serve remote west side sites near Firebaugh and Mendota?
Yes. Remote sites are normal for us. Long drives affect the service schedule, so we plan pump-outs to match the crew size and tank capacity. Send us the road in and any gate rules.
Can packinghouses rent a restroom trailer for the whole season?
Yes. Many yards keep a unit from the start of stone fruit in May through the end of the season in fall. We write the full season into one order and service it on a set schedule.
Can restroom trailers support a flood shelter in the Tulare Lake basin?
Yes. We set units on the highest firm ground at the shelter and run them on their own tanks. Call as soon as the shelter opens, and we'll tell you honestly how soon a unit can arrive.
Can you deliver to fire staging areas along Highway 168?
Yes. We deliver to staging areas and camps in the foothills and mountains. Tell us the location and road conditions, and we'll confirm the right unit for the route.
Can growers and contractors rent from you on a long-term contract?
Yes. Rail segments, school projects and seasonal farm work can all run on long-term terms. We build moves, swaps and extensions into the contract so it follows the job.
How do we request a quote for several sites at once?
Send us a list of sites with the crew size and dates for each. We'll return one quote that covers every unit, every move and the service schedule.

Fresno restroom trailer guides for farms, public works and school districts

A dirt road between almond orchard rows

Keeping restrooms close to a moving harvest crew

Harvest crews move fast. A crew picking grapes or shaking almonds can clear a block in a day or two and move a mile down the road. Restrooms that stay at the shop fall behind right away.

Start with the harvest calendar. Stone fruit starts in mid-May, grapes in mid-July, almonds in August and raisins in September. Share your block plan for each window, and we'll plan the unit moves ahead of time.

Place units at the end of the rows. Crews working toward the end of a row can reach the restroom without walking the length of a block. Keep the unit on firm ground next to a ranch road so our truck can reach it.

Put water and restrooms together. Cal/OSHA's heat rule calls for cool water close to the work and names agriculture directly. A restroom next to the water station and the shade area makes the break area one stop.

Plan for the heat. Crews drink more and use the restroom more on hot days. We pump more often from June through September so units don't fill before the next visit.

Keep handwashing easy. Our units have running water sinks, and we refill the fresh water on every visit. Crews can wash before eating without walking back to a truck.

Exposed pipes in a street excavation

Planning restrooms for a block-by-block downtown rebuild

Replacing water and sewer lines downtown means opening one block, fixing it and moving on. Every block is its own small jobsite. Restrooms need to move just as often.

Use compact units. A 2-Station trailer fits inside a single-lane closure and runs on one standard circuit. It can move with the crew every time the work shifts.

Place units inside the traffic control zone. That keeps them away from moving cars and pedestrians. It also keeps the path from the work to the restroom short and safe.

Write the moves into the order. Share the block schedule with us, and each move becomes a phone call and a date. There's no new paperwork each time.

Keep neighbors in mind. Downtown businesses stay open during the work. A clean, closed trailer is far easier to live with than open booths on the sidewalk.

Plan for the hottest weeks. Downtown pavement soaks up heat, and crews in an open trench feel it all afternoon. We tighten the pump-out schedule in summer and keep the unit's air conditioning running, so the restroom stays a cool place to step into on a break.

The City of Fresno posts updates on public works projects and street closures. Those updates help crews and vendors plan the next move before it arrives.

Rows of solar panels from above

Restrooms for remote solar builds on the west side

Utility-scale solar work puts large crews on open land far from town. The Darden Clean Energy Project on Fresno County's west side covers 9,500 acres and is expected to bring more than 2,000 workers for up to three years.

Distance changes everything. A crew that has to drive to town for a restroom loses a big part of each break. Restrooms need to be on site and spread out across the work areas.

Use large units at the gate and small ones in the field. An 8-Station unit near the site office serves shift changes and meetings. Smaller units closer to the arrays serve crews during the day.

Plan service around the drive. Long trips to remote sites mean fewer visits, so tank size matters. We'll size units and schedule pump-outs so no unit fills between visits.

Think about heat and dust. West side summers run hot, and dust gets into everything. Air conditioning and closed doors keep the inside clean and cool. Crews living near the site may also need California shower trailers for remote solar crews.

The California Energy Commission tracks large energy projects across the state. Its project pages help planners see how long a build will run and how many workers it will need. Long builds like that suit long-term restroom trailer rentals for rail and solar contracts.

A temporarily closed for construction sign on a fence

Modernizing old school buildings without closing the campus

More than two-thirds of Fresno Unified's schools were built before 1970. Measure H pays to repair and modernize them. Many of those projects reach into restrooms and plumbing, often while school is in session.

The school still has to run. Students need restrooms close to their classrooms, and younger students need more help. A trailer placed near the closed wing keeps the day on track.

Match the trailer to the campus. The ADA +6 gives students a ramp entry plus six standard stations. Large middle and high schools may need an 8-Station unit as well.

Plan supervision. Put units where staff can see the door, such as near the office or the playground gate. Lock them after school and on weekends.

Schedule around the bell. We deliver and service before school, after dismissal or on weekends. No truck needs to cross a campus during recess or lunch.

Think about the summer break. Many districts push the heaviest work into June and July, when campuses are nearly empty. A large unit can serve the construction crew during those months, then swap for an ADA +6 when students return in August.

Fresno Unified publishes information on its bond program and campus projects. Facilities teams can use that project list to plan restroom coverage for each site before work begins.

Flooded farmland from above

Flood season restroom planning in the Tulare Lake basin

The winter of 2023 brought about a dozen atmospheric river storms to California. South of Fresno, the old Tulare Lake basin filled with water again. Levee breaches led Tulare County to order evacuations west of Highway 43, affecting about 1,000 people in Allensworth and Alpaugh.

Small towns have small shelters. A church hall or a school gym may have only a few restrooms. When families sleep there, those restrooms fall far short.

Flood zones add another problem. Local water and sewer systems may be damaged or shut off. Self-contained trailers carry their own water and hold their own waste, so they keep working.

Pick high ground for every unit. Pick the highest firm spot at the shelter, away from ditches and low areas. Water can rise for weeks after a storm as reservoirs release runoff.

Plan for a long stay. In 2023, high water kept flowing into the basin through spring and summer. Families may be away from home for a long time, so set the service schedule for weeks.

Stage units before the water comes. When forecasters warn of a string of storms, emergency planners can ask us to hold units for likely shelter sites. Units that are ready to roll cut the wait once the first evacuation order goes out.

The California Department of Water Resources tracks flood conditions and reservoir releases. Emergency planners can use its updates to decide when to stage restroom trailers near likely shelters.
