How much space does a 4 stall restroom trailer need?
Plan for a level pad plus room to maneuver. Delivery crews generally want about 60 feet of straight clearance behind the trailer to back it into place, the same clearance a roll-off dumpster rental needs on the same job site. Cary lots vary block to block, so Cary Porta Pros walks the site before delivery day rather than guessing off a satellite photo. If the trailer will sit near a sidewalk or public right of way anywhere in Cary, that placement needs confirming with the city; we do not assume a rule we have not checked. This is also the point to decide whether you need an ADA accessible porta potty nearby, since a 4 stall trailer alone does not always satisfy accessibility on its own. For accessible units, ADA Standards section 213.2 requires that at least 5 percent of clustered single-user units be accessible, with a minimum of one, and section 304.3.1 calls for a 60 inch turning circle. Compare that against a 2 stall restroom trailer or the larger 8 stall restroom trailer before you commit to a count, and check the restroom trailer rental cost page for how size changes price.
Is a 4 stall restroom trailer enough for my event or job site?
It depends on headcount and hours, not just guest list size. On a construction site, OSHA 1926.51(c)(1) sets the baseline: 1 toilet facility per 20 workers, moving to 1 toilet and 1 urinal per 40 workers once the crew passes 20. A 4 stall trailer can cover a mid-size crew that a single portable toilet rental unit cannot, especially on multi-week jobs tracked through construction site services. For weddings and private events, guest comfort matters more than a bare code minimum, which is why couples booking a wedding restroom rental in Cary often step up from standard units to a trailer with running water. If your event runs past dark, pair the trailer with a light tower rental and confirm power draw with a temporary power pole if the venue lacks an outlet. Festival organizers using our festival restroom rental service, and race directors reading the marathon and race restrooms guide, generally size up once attendance clears a few hundred.
What comes standard inside a 4 stall restroom trailer?
Expect four private stalls, sinks with running water, and interior lighting, a step above the deluxe flushable porta potty line. Handwashing meets 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device, not hand sanitizer alone; if your event also needs a standalone station, see handwashing station rental or handwashing requirements for the difference. Compare trailer tiers on the luxury restroom trailer page if you want upgraded finishes, or check the shower trailer rental option for multi-day events near Cary where crews or guests need to clean up. For general planning, the how many porta potties do I need guide and the porta potty placement guide both apply the same spacing logic to trailers.
How much does a 4 stall restroom trailer cost to rent in Cary?
Daily trailer rentals in our data range from 175 to 2,500 dollars depending on tier and add-ons, while a full weekend runs 900 to 3,000 dollars and a multi-day event package runs 2,499 to 3,899 dollars. See the full restroom trailer rental cost breakdown before requesting a number.
Does the trailer need a dedicated water and power hookup?
It needs both, though options vary. Some trailers run on onboard tanks and battery power for short events; longer bookings usually want a garden hose connection and a standard outlet. Ask about your specific unit when you request a quote.
Can I rent a 4 stall restroom trailer for a construction site instead of an event?
Yes. Crews doing renovation or new-build work in Cary use them the same way they would a home renovation porta potty setup, just with more capacity and real plumbing for longer shifts.
How far in advance should I book for a wedding or festival?
Book as soon as your date and headcount are set. Trailers move fast during spring and fall weekends, and popular Cary dates near Morrisville, 5.7 miles north, or Apex, 8.2 miles southwest, can book out early.
What is the difference between a 4 stall and an 8 stall trailer?
Stall count sets throughput, not just space. An 8 stall restroom trailer suits crowds pushing past 300, while 4 stalls handles most weddings, small festivals and mid-size crews comfortably.
