A 4 stall restroom trailer handles 100 to 150 guests comfortably at an event, and it works for multi-day construction jobs too. Rental runs from a few days at 800 to 2,500 dollars a day up to a full week or event package. Vallejo Porta Pros delivers and services them across the city.
Four private stalls, running water, and climate control if you need it. This sits a level above the standard porta potty rental most job sites use, closer to what you'd get from a deluxe flushable porta potty but built for higher traffic. Vallejo Porta Pros sets these up for weddings, festivals, and construction crews that want something better than a row of standalone units.
If your event needs accessible facilities, ask about an ADA accessible porta potty added alongside the trailer. ADA Standards section 213.2 requires that at least 5 percent of a cluster of single-user units be accessible, never fewer than one, and the trailer itself needs a stable, slip-resistant approach path under ADA Standards section 302.1. Placement matters as much as unit count. Check our porta potty placement guide before delivery day, since driveways in older Vallejo neighborhoods aren't always wide enough for a trailer this size.
Compare it against the 2 stall restroom trailer for smaller gatherings, or step up to the 8 stall restroom trailer for anything over 150 guests. A shower trailer rental or luxury restroom trailer covers events that need more than toilets.
Pricing depends on how long you need it and what day it delivers. Here's the general range:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Multi-day event | $2,499 | $3,500 | $3,899 |
A single weekend booking, say a Friday delivery for a Saturday wedding, typically lands near the weekend figure above. For full breakdowns including delivery fees, see restroom trailer rental cost or our general porta potty rental cost page. Weekly renters comparing against standard units should look at porta potty rental per day and monthly porta potty rental pricing too, since a long construction job sometimes costs less with standard units plus a trailer combo than an all-trailer setup.
Guests notice the difference. A trailer with running water and real stalls reads differently than a bank of porta john rental units lined up along a fence. For wedding restroom rental bookings and festival restroom rental setups in Vallejo, trailers are the standard ask now, not the upgrade.
Delivery access matters here more than people expect. A roll-off truck needs about 60 feet of straight clearance behind it, and trailers need similar room to maneuver and level. That's tight on some downtown Vallejo lots, easier at open venues. Crews planning construction site services should count workers against OSHA 1926.51(c), which sets 1 toilet for 20 workers or fewer on a job site, scaling up from there. A trailer alone rarely satisfies that ratio on a big crew, so many contractors pair it with portable restroom rental units for the workforce and keep the trailer for site visitors or supervisors.
Handwashing is separate from toilet count. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not sanitizer alone, and a handwashing station rental or portable sink rental covers that requirement cleanly. For events pulling from American Canyon, 6.2 miles north, or Benicia, 7.8 miles east, Vallejo Porta Pros handles delivery across that radius without an extra trip charge structure that changes by zone.
A 4 stall trailer covers roughly 100 to 150 guests for a single-day event. Larger weddings or festivals should look at the 8 stall restroom trailer instead. See how many porta potties do I need for a fuller breakdown by headcount and event length.
Most units run self-contained with onboard water and holding tanks, though some configurations want a nearby power source. Ask Vallejo Porta Pros what your specific site needs before delivery.
