Why The Lavatory NorCal Is #1 for Temporary Bathroom Trailer Rentals
A rental that lasts a year has to hold up for a year, through summer heat in the valley and winter rain on the coast. Ours do. Every trailer in our fleet is a heavy-duty, commercial-grade unit on a steel frame, with gel-coated fiberglass walls that wipe clean and an AC unit with heat strips for cold mornings, and we own every one of them, so the company that quotes you is the company that services you in month nine. Strictly luxury. Never plastic.
Google, Tesla, Amazon, PG&E and Target have all rented from our network, and so have school districts, county fairs and film crews that need clean restrooms on a schedule they can count on. We are licensed and insured, A+ rated by the BBB and backed by hundreds of 5-star reviews. Call us for a quote on a weekend or a whole school year. If you would rather type it out, send the quote form and our dispatch team will call you back fast with sizes, dates and a clear price.
“We used The Lavatory NorCal for a long-term corporate rental in Santa Clara, and they beat every expectation. The unit stayed clean and well kept and felt like part of our office. They were proactive with maintenance and quick to answer every question. We will absolutely work with them again.”
“The Lavatory NorCal is always prompt with delivery, the portable restrooms are very clean, and the service is professional. Highly recommended if you need temporary facilities for an event or for facility maintenance in the Bay Area.”

Short Term Restroom Trailer Rentals for a Day or a Few Weeks
Plenty of our rentals are over in a weekend. A backyard wedding in Los Gatos, a company picnic at a park in Pleasanton, a two-day film shoot on a closed street in San Francisco or a weekend festival at a Central Valley fairground each needs good bathrooms for a short window and nothing after. We usually deliver the day before, set the unit level, stock it full and pick it up the day after, and we work around venue rules on drop-off and pickup times when a park, winery or hotel has them.
Short rentals also cover surprises. A water main breaks under an office in Fremont. A restaurant’s plumbing fails on a Friday afternoon, right before the dinner rush and a full weekend of reservations. A school gym floods before a tournament. For those calls our emergency restroom trailers for Bay Area and Sacramento outages roll 24/7, and a short rental can turn into a long one if the repair drags on. You never have to swap companies when the plan changes, because the same dispatch team that sent the first trailer simply keeps your rental open as long as you need it.
Long Term Portable Restroom Rentals for Months or a Full Year
Long rentals are where the build quality shows. We set semi-permanent bathroom trailers at schools during modernization work, at banks and offices while their restrooms are rebuilt, at city parks waiting on a new restroom building, at plants adding a shift, and at construction sites that run for a year or more. A trailer looks and works like a real restroom, so nobody on site has to settle for a row of plastic porta potties for months on end while the real restrooms are torn out and rebuilt.
We build each long rental around the site. You can run the trailer on its onboard fresh and waste tanks with a service schedule, or connect it straight to your building’s water and sewer so it needs far fewer visits. Each unit sits on a steel frame with a tough polypropylene waste tank. Inside, the one-piece fiberglass stands up to heavy daily use for months without showing it. If your team wants to do the daily wipe-down, that works. If you want us to handle all of it, that works too.

Sizes of Private Stall Bathroom Trailers for Any Rental Length
Size depends on three things we ask about on every call: the head count, the number of hours the unit will be in use, and how much flat space you have for it. A 2-stall handles up to 150 guests at a party. A 5-stall covers 150 to 450 people, or 200 to 500 at a five-hour event, and the 9-stall handles 400 to 900. For daily staff use on a long rental, we size by the number of workers and their shifts instead of a guest count, and we will walk you through it on the phone.
| Unit | Layout | Fits best |
|---|---|---|
| 2-stall bathroom | 1 women’s room, 1 men’s room with urinal | Up to 150 guests |
| 3-stall bathroom | 2 women’s rooms, 1 men’s room | Tight lots, mid-size groups |
| 5-stall bathroom | 3 women’s stalls, 1 men’s stall plus a urinal | 150 to 450 people |
| 9-stall bathroom | 5 women’s stalls, 2 men’s stalls plus 2 urinals | 400 to 900 people |
| 8-stall private bathroom | 8 unisex rooms, each with its own door | Offices and long shifts |
| ADA plus 2 bathroom | 1 accessible room plus 2 private rooms | Up to 200 guests or 30 workers |
| ADA plus 6 bathroom | 1 accessible room plus 6 stalls | Large sites that need access |
Most long-term customers in offices and plants pick the 8-stall private bathroom trailer for long shifts in Silicon Valley, since every room is unisex and has its own locking door. Busy public sites lean toward the 9-stall luxury restroom trailer for big Sacramento crowds. Every size sits under our portable bathroom trailer rentals for Northern California, where you can compare floor plans side by side.
Hookups for a Temporary Restroom: Tanks, Plumbing and Power
Power comes first. Our 2-stall, 3-stall and 5-stall units each need one dedicated 120 volt, 20 amp circuit within 100 feet, and the 9-stall and the ADA plus 2 each need two. A normal exterior outlet often works as long as nothing else shares the breaker. No outlet nearby? We bring a quiet generator, set it far enough from the doors that nobody hears it, and keep it fueled on our regular service visits.
Water and waste come next. On tanks, the 2-stall carries 105 gallons of fresh water with a 300 gallon waste tank, and the 5-stall carries 200 gallons fresh with 520 gallons for waste, which sets how often we pump. For rentals of several months, a direct hookup to a water line and a sewer cleanout cuts service visits way down. We tell you which way costs less over your rental period, and we can switch a site from tanks to plumbing halfway through if the project runs longer than planned.
Where Long Term Mobile Restroom Trailers Fit in Northern California
School districts across the South Bay and the East Bay schedule restroom projects and campus modernization for summer and often run into the fall, so a trailer bridges the gap while students are back. Banks and offices in Walnut Creek, Palo Alto and downtown Sacramento remodel their restrooms floor by floor. Food processing plants and packing houses in the Central Valley, from Modesto to Yuba City, add seasonal shifts at harvest and need more restrooms close to the line. City parks departments keep a trailer at a busy park while a new restroom building goes up.
Workplaces have head count rules to meet, and an inspector who visits a long project will check them. Cal/OSHA’s general industry toilet rule in Title 8, section 3364 sets a minimum number of toilets based on the number of employees, and we size a long rental to match it. If your crew also needs showers on a long remote job, our mobile shower trailer rentals across NorCal job sites pair well with a bathroom unit on the same service route.
Typical Setups for Semi-Permanent Restroom Trailers
These are setups we see over and over on long rentals in the region. Details change from site to site. The plan stays close.
A school modernization in San Jose
An elementary school closes both restroom wings for new plumbing work that starts in June and runs past Thanksgiving. We set two bathroom trailers and an ADA plus 2 on the paved yard near the classrooms, connect them to school power, and pump and restock twice a week before the first bell. The principal told us that by the second week the kids had stopped asking where the old bathrooms went and simply lined up at the trailers like it had always been that way.
A bank branch remodel in Walnut Creek
A busy branch guts its staff and customer restrooms for eight weeks. We place a 2-stall unit in the back corner of the lot, run it on the branch’s power, and service it every Monday. Customers use it without a second thought, and the bank staff no longer have to walk next door to a coffee shop every time they need a restroom.
Harvest season at a Central Valley packing house
A packing house near Modesto adds a night shift from late July into October. We bring an 8-stall private bathroom trailer and park it by the dock doors so workers are not crossing the yard in the dark. The plant manager liked the setup enough that he asked us to hold the same unit for the next harvest before this one was even over.
We handle long rentals like these all over the region. Our pages for long-term restroom trailers in Oakland and Fremont portable restroom trailer rentals cover the East Bay, and our restroom trailer service areas across Northern California show every other city we cover.
How Renting a Temporary Restroom Trailer Works
- Call us. Ring (209) 202-3741 or send the quote form with your dates, address, head count and hours.
- We size it. We pick the unit and the service plan that fit, and you get a free quote with no hidden fees.
- We deliver and level it. Our driver sets it level on its jacks, sets up the stairs and rails, connects power and water or plumbing, and tests every flush and light.
- We service it. We pump, refill, clean and restock on a fixed day, as often as your site needs it.
- We haul it out. When the project wraps we pick it up and leave the ground clean.
Service Plans That Keep a Long Term Restroom Trailer Clean
On a long rental the service plan matters as much as the trailer. We are a direct fleet and not a broker, with 30+ years of rental know-how behind our partner companies, so the service workers who show up on service day work for us. We set a fixed service day, once a week for a small office and up to daily for a plant running 3 shifts, and each visit we pump the waste tank, refill the fresh water, clean every surface and restock paper, soap and towels.
Need a change? Call. If your head count jumps, we add a unit or swap to a larger size without pulling the old one until the new one is ready. If something breaks on a Sunday night, our 24/7 line gets a service worker on the way. Public buyers can also find us on SAM.gov, and our five-star record with schools and agencies is a big part of why they keep calling back. We have also supported FEMA and the American Red Cross on disaster work. We keep spare units staged so a swap never leaves you without a restroom.
Accessible Units for Long Term Bathroom Trailer Rentals
Schools, public agencies and most large employers need at least one accessible restroom on site for the full length of a rental. Our ADA plus 2 and ADA plus 6 units have a built-in ramp, a wide door, grab bars and room to turn a wheelchair, built to the 2010 ADA Standards for Accessible Design and the California standard. The ADA plus 2 sits lower during setup to shorten the ramp. See our ADA accessible trailer rentals in the Bay Area and Sacramento for floor plans and the shower versions.

“Their service team cleans the units at our schools in Hayward every week, from January until now. The restrooms are really clean and luxurious, and the whole team is polite and easy to work with.”
“They were honest and easy to talk to. They laid out a plan for our site in Stockton and followed through. We got compliments from our employees and our customers on how clean the facilities were. They are one of our preferred vendors now.”

Questions About Short and Long Term Restroom Trailer Rentals
What is the shortest and longest rental you offer?
We rent for as little as one day and for as long as a year or more. Many school and construction rentals run from several months to well past a year, and you can extend at any time with a call.
Can the trailer connect to my building’s water and sewer?
Yes, on most long rentals. A direct hookup to a water line and a sewer cleanout means far fewer service visits. We look at your site first and tell you if it makes sense.
Who cleans the trailer during a long rental?
We do, on a fixed schedule, and we pump, refill and restock on every visit. Some customers have their own cleaning staff do a quick daily wipe-down between our visits, which is easy on fiberglass walls.
What if my project runs longer than planned?
Call us and we extend the rental. Nothing has to move, the service schedule keeps going on the same day of the week, and you get an updated quote for the extra months.
Do I need a permit to keep a trailer on a street?
Often, yes. Many Bay Area cities want a street-use permit for anything parked in the right of way for more than a short stop. On private lots you usually do not need one, and we can help you find the right spot.
How fast can you start a rental?
Fast. We offer same-day delivery and 24/7 immediate dispatch, and for urgent calls we can often be there within 1 to 2 hours. Planned long rentals usually start on the day you pick.
