What Is a 4 Stall Restroom Trailer?
It is a towable trailer split into four separate restrooms, each with its own door, sink and flushing toilet, so there is no shared entry line like you get with clustered standard porta potty rental units. Most jobs pick this size once headcount climbs past what a couple of deluxe flushable porta potty units can handle comfortably. Compare it against the smaller 2 stall restroom trailer or the larger 8 stall restroom trailer before you commit. For weddings and private events, a lot of South Whittier customers step up to the luxury restroom trailer line instead.

Where Can We Place the Trailer, and Is Delivery an Issue?
Placement in South Whittier depends on your lot and, if it touches a public sidewalk or curb, on confirmation with the city; that part is not verified and should be checked before delivery day. Our porta potty placement guide covers ground clearance and slope. A roll-off style delivery truck needs about 60 feet of straight clearance behind it to set the trailer down safely, so tight driveways and alleys need a walkthrough first. If you are running a construction schedule, pair the trailer with construction site services and a temporary fence rental around the unit. South Whittier Porta Pros also serves nearby cities: Santa Fe Springs sits 2.4 miles west, La Mirada 3.0 miles southeast, and Cerritos 6.7 miles southwest, so a delayed delivery window rarely means a long haul.

Do We Need Anything Else on Site With It?
Most jobsites still want a handwashing setup near work areas, separate from the trailer itself. OSHA 1926.51(a)(1) requires an adequate supply of potable water at all places of employment, and 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at washing stations, not sanitizer alone. Add a handwashing station rental or a portable sink rental if crews are painting or using chemicals, since OSHA 1926.51(f)(1) covers washing after paints, coatings, herbicides or insecticides specifically. Larger builds often add a roll-off dumpster rental and a storage container rental alongside the trailer.
How many people can one 4 stall restroom trailer serve?
There is no fixed OSHA number for trailers specifically, but the toilet ratio in 1926.51(c)(1) is one facility per 20 workers up to 20, then one seat and urinal per 40 up to 200. Four private stalls comfortably covers crews in the 50 to 150 range for a standard workday in South Whittier.
Is a 4 stall trailer wheelchair accessible?
Not automatically. ADA Standards 213.2 requires at least 5 percent of clustered single-user units to be accessible, with a 60 inch turning circle under 304.3.1 and a 32 inch clear door under 404.2.3. Ask for an ADA accessible porta potty unit alongside the trailer if your event needs one.
How long can we rent a 4 stall restroom trailer?
Day, week, weekend, and multi-day event terms are all standard, shown in the table above. Longer construction jobs usually rent by the week or month; check monthly porta potty rental for that comparison if the trailer is overkill for daily use.
Does the trailer need a power hookup?
Most 4 stall units run interior lighting and pumps off a standard outlet or an onboard battery; heavier deluxe models may need more. Ask about a temporary power pole or a light tower rental if the site has no power source nearby.
What is delivery like for South Whittier addresses?

South Whittier Porta Pros delivers throughout South Whittier and to nearby cities like Santa Fe Springs, 2.4 miles west, and La Mirada, 3.0 miles southeast.
