Why The Lavatory NorCal Leads in 5-Stall Portable Restroom Rentals
Strictly luxury. Never plastic. Our entire fleet is made up of commercial-grade bathroom trailers, every one of them owned by us and maintained in our own yard, which means nobody hands your order to a subcontractor at the last minute. Our family has more than 30 years of experience in event and equipment rental, serving customers in every corner of Northern California. Companies like Google, Tesla, Mercedes, Target, eBay and Caesars Palace have rented our trailers, and so have the Oakland A’s. We are licensed and insured, rated A+ by the BBB, and backed by a long list of five-star Google reviews from customers across the Bay Area and the Sacramento Valley.
The 5-stall is the #1 size we deliver for bigger gatherings, because it gives the women’s side three stalls and keeps the men’s line on its own door. Call us with the date, the address and an estimate of the guest count, and we will quote it the same day. Prefer to type it out? Send a quote request through our form and we will reply quickly.

Two Separate Rooms, Five Stalls: Inside the Deluxe Bathroom Trailer
The trailer is split into two rooms with two entrances, one for women and one for men, and each entrance has its own stairs and railings. On the women’s side, three private stalls with full doors line one wall. Across from them is a long vanity, where two steel sinks are set into a stone-look counter below a wide framed mirror. That layout matters more than it sounds, since guests who only want to wash their hands or fix their hair never block anyone waiting for a stall. The men’s side has one stall, one urinal and its own sink. Both rooms share the same finishes: wood-look floors, framed art, bright LED lights, and foot-pedal flush toilets that feel like the ones at home.

Guest Counts From 150 to 450: Sizing a Mobile Restroom Trailer
Most customers land on this size when the guest list runs somewhere between 150 and 450 people. A shorter party of about five hours can stretch toward 500, because guests come and go over the evening instead of all at once. A full-day festival, an open bar or a crowd that breaks at the same moment, like halftime or the end of a ceremony, pushes the other way. We ask about those details on the first call.
Tanks set the limit on long events. The 200 gallon fresh water supply and the 520 gallon waste tank carry most single-day rentals without a service stop, and on weekend or week-long jobs we schedule pump-outs before the tanks ever get close to full. Larger than 450? Pair two trailers, or step up to the 9-stall. Need a wheelchair accessible room as well? Add an accessible unit next to it.
Not sure where your count lands? Call (209) 202-3741 and walk us through the day. The quote is free, and so is the advice.
Where the 5-Stall Portable Restroom Works Across the Bay Area and Sacramento Valley
The 5-stall goes to more kinds of jobs than any other size we rent. Here are three typical setups we see every year, written as composites of many deliveries rather than one customer’s event.
A company picnic on a Silicon Valley campus
A tech company in Mountain View or Sunnyvale invites 400 employees and their families to a summer picnic on the campus lawn, far from the nearest building restroom. We set the 5-stall on the edge of a parking lot close to the food trucks, run power from a site outlet the facilities team cleared ahead of time, and point the lit entrances toward the lawn so the doors are easy to find after dark. One unit carries the whole afternoon.
A fair or festival vendor area in the Valley
County fairs and summer festivals from Pleasanton to Sacramento often bring in a luxury restroom for VIP tents, sponsor areas and vendor staff. The trailer stays for the full run, usually ten days or more, and our team returns overnight to empty the waste tank, refill the water and restock paper so the morning opens clean. The air conditioning earns its keep on 100 degree July afternoons.
A school campus during a restroom remodel
A high school in the East Bay closes a restroom building for a summer renovation that runs into the fall semester. The district places the 5-stall near the gym, and our technicians service it on a fixed schedule before first period. Students get real stalls with doors and running water while the contractor finishes the job.
If a broken water main or a power outage has shut down your building, our emergency restroom trailers for the Bay Area and Sacramento can roll any hour of the day. For a wedding with two or more units, our luxury event restroom rentals for NorCal weddings page explains how we lay out a full venue.
Summer Heat, Coastal Fog and Winter Rain: Weather Planning for Luxury Restroom Trailers
Northern California can give you three climates in one afternoon drive. Sacramento and the rest of the Central Valley often pass 100 degrees from June through September, and the National Weather Service keeps a clear heat safety guide worth reading before any outdoor event in that stretch. Inside our trailer, the rooftop air conditioner keeps both rooms comfortable, which guests notice the moment they open the door. On a work site, Cal/OSHA’s heat illness prevention rule in Title 8, section 3395 already has supervisors planning water, shade and breaks, and a cool, clean restroom fits right into that plan.
Head toward the coast and the problem flips. Summer fog in San Francisco, Pacifica and Half Moon Bay can drop evening temperatures into the 50s, and the same unit switches to heat with a tap on the thermostat. Winter storms bring a different challenge: soft ground. When the forecast calls for a heavy rain, we look at the drop spot ahead of time, set the leveling jacks on wide pads, and keep the stairs and railings firmly anchored so nobody slips.
Booking a Temporary Restroom Trailer in Five Steps
- You call. Dial (209) 202-3741 or use the quote form, and give us the location, the dates and your expected guest count.
- We pick the right size. We check that the 5-stall matches your crowd and your space, suggest a pairing if needed, and send a clear quote with no hidden fees.
- We deliver and level. Our driver positions the trailer, levels it, sets both stair platforms, connects power and water, and tests every toilet, sink and light.
- We service on schedule. For longer rentals we empty the waste tank, refill fresh water and restock every stall on the days that work for you.
- We haul it away. After the event we disconnect, load up and leave the site as clean as we found it.
Setup Needs: Power, Water and a Level Pad for the Restroom Trailer
The 5-stall needs one dedicated 120 volt, 20 amp circuit within 100 feet of where it parks. A building outlet usually works as long as nothing else, like a sound system or a catering warmer, shares that breaker during the event. No outlet? We bring a quiet generator and place it away from the crowd. The trailer carries its own 200 gallons of fresh water, so a hose connection is helpful on long rentals but not required.
With the stairs set, the unit is about 20 feet long and a little over 12 feet wide, so plan on a flat area roughly the size of two parking spaces. Pavement is ideal. Firm grass or compacted gravel works too. Leave a clear path for our truck, and if the spot is on a public street, ask your city about a permit before delivery day.
What Customers Say About Our Deluxe Bathroom Trailers
“The Lavatory NorCal was a godsend for a fundraiser I planned in Menlo Park. The trailer added a classy touch for our guests, and the company was professional and easy to work with. Highly recommended for any special occasion.”
“We used them for a company event in Pleasanton and the restrooms were spotless. The team was on top of every detail and gave us the luxury experience we were hoping for.”
“They were honest and easy to talk to. They laid out a plan and followed it, and we got compliments from employees and from our best customers on how clean the facilities were. They are now one of our preferred vendors.”
“We needed something better than porta potties for a client event with executive partners in Palo Alto. I got a lot of thanks for this one. Super clean, with AC and heat. What else could you ask for?”
“At a wedding near Davis, a water valve broke on a Saturday night and the venue had no working bathrooms. One call to The Lavatory NorCal and they arrived within the hour. Quick, friendly and clean. Thank you!”

Five-Stall Bathroom Trailer Questions, Answered
Why are there only two doors on a five-stall trailer?
Each door opens into a room, not a single stall. The women’s room holds three stalls with doors and two sinks, and the men’s room holds a stall, a urinal and a sink, so five people can use the toilets at the same time.
Can I rent two 5-stall trailers for one event?
Yes. Large weddings, fairs and corporate events often use two units at opposite ends of the venue, which shortens walks and lines. We can also mix sizes, such as a 5-stall plus an accessible trailer.
Will the trailer stay comfortable in July heat?
Yes. The rooftop unit cools both rooms on the hottest Valley afternoons and turns to heat when fog rolls in at night. We set the thermostat during delivery.
Do you staff the trailer during the event?
We can. Ask about an attendant when you book, especially for weddings and VIP areas where someone keeps the counters wiped and the supplies full all evening.
How quickly can a 5-stall arrive?
We run 24/7 immediate dispatch and same-day delivery, and for emergencies we can often be there within 1 to 2 hours. Graduation weeks and fair season fill fast, so book early when you can.
