How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably cover mid-size crowds, roughly 100 to 150 guests over a few hours, more if the event stretches across a full day with breaks. Chino Hills Porta Pros sizes trailers against ANSI/PSAI Z4.3, the baseline service interval standard for portable sanitation, then adjusts for your headcount and hours. Construction crews lean on OSHA 1926.51(c) ratios instead, since a jobsite with 20 or fewer workers can run on far less than a 4 stall unit. If your guest count sits near the edge, our restroom trailer rental page walks through sizing, or compare against the smaller 2 stall restroom trailer and the larger 8 stall restroom trailer before you commit. Weddings in Chino Hills often pair a 4 stall trailer with a luxury restroom trailer upgrade for the bridal party. Need water for handwashing too? Add a handwashing station rental at the entrance to keep lines moving.
What Does a 4 Stall Restroom Trailer Cost in Chino Hills?
Pricing depends on the rental window and the finish level you pick.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| event | 2499 | 3500 | 3899 |
A single weekend rental in Chino Hills typically runs in the 900 to 3000 dollar range, depending on trailer finish and add-ons. Multi-day construction jobs usually land on the day or week rate, while weddings and festivals book the event tier, which includes setup, breakdown and standby service. Full cost breakdowns live on our restroom trailer rental cost page, and general portable toilet pricing sits on porta potty rental cost if you're comparing against standard units. Ask about delivery separately; most quotes list it apart from the trailer rate, and our request a quote form breaks both out clearly.
Where Can We Place the Trailer on Site?
Placement depends on ground and access more than anything else. The trailer needs a level, stable surface, consistent with ADA Standards 302.1's requirement that floor and ground surfaces stay firm and slip resistant, and delivery trucks need roughly 60 feet of straight clearance behind them to back in safely. In Chino Hills, that usually means clearing a driveway or lot section before our crew arrives. If you're near Eastvale, about 13.7 miles east, we run that route regularly and can coordinate delivery timing across both areas. Placement in the public right of way needs confirming with the City of Chino Hills before we set anything at the curb line. Our porta potty placement guide covers ground clearance and slope in more detail, and the dumpster permit requirements page is a useful reference if you're renting a roll-off dumpster rental alongside the trailer for a renovation project.
Do 4 Stall Restroom Trailers Have Running Water?
Yes. They flush and include a sink with soap and towels, meeting the intent of 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device at washing stations. Hand sanitizer alone doesn't satisfy that standard. Compare that to a deluxe flushable porta potty if you don't need a full trailer.
Can We Get an ADA-Accessible Stall Added?
Yes, on request. Where units are clustered, ADA Standards 213.2 calls for at least 5 percent accessible, never fewer than one. See ADA accessible porta potty for standalone options and ADA restroom requirements for the full standard.
How Far in Advance Should We Book for a Chino Hills Wedding?
Book as soon as your date and guest count are set, especially for weekend events, since trailer inventory is limited. See wedding restroom rental and event restroom rental for seasonal booking guidance.
Do You Service the Trailer During a Multi-Day Rental?
Yes. Service intervals follow ANSI/PSAI Z4.3 guidance and scale with usage. Ask about your schedule when you request a quote.
What's the Difference Between This and a Standard Unit?
A 4 stall trailer flushes, has climate control and separates by gender; a standard porta potty rental is single-occupant with a holding tank.
