A 4 stall restroom trailer serves crews and events up to a few hundred people a day without a line forming at every break. Bismarck Porta Pros sets these units on job sites, weddings and festivals across the city, and weekly rental for a trailer this size typically runs 150 to 1650 dollars depending on stall count and hookups. It beats stacking eight standard porta potties side by side.
Four stalls comfortably cover a crew of 60 to 100 workers over an eight hour shift, or a few hundred guests cycling through an event in Bismarck over a few hours. For construction sites, OSHA 1926.51(c)(1) sets the baseline at one toilet for 20 workers or fewer, one toilet and one urinal per 40 from there, so four stalls with urinals can carry a crew well past what a bank of standard rentals would need. If your headcount runs higher, pair this with an 8 stall restroom trailer instead of doubling up on smaller units. Curious about your exact number? Run it through how many porta potties do I need before you book, and check OSHA portable toilet requirements if the job is under inspection.
Expect climate control, running water, and interior lighting that beats anything you get from a standard porta potty rental. Handwashing sinks are built in, which matters because 29 CFR 1910.141(d)(2) requires soap and towels or a hand dryer at washing stations, not just sanitizer. Some trailers step up to full flush fixtures similar to a deluxe flushable porta potty, and one stall can be built to ADA Standards, including the 32 inch clear door opening under section 404.2.3 and the 60 inch turning circle under section 304.3.1. If your event needs a fully accessible unit on its own, look at the ADA accessible porta potty page instead. Compare trailer tiers on the restroom trailer rental page, or check the luxury restroom trailer if you want upgraded finishes for a wedding.
Placement needs a level, firm surface, and stability matters more on a trailer than on a single unit. ADA Standards section 302.1 calls for stable, firm, slip resistant ground on any accessible route, and that same footing keeps the trailer from settling unevenly during a multi-day rental. Delivery trucks generally need clear approach and backing room similar to what a roll-off needs, and a straight run of about 60 feet behind the unit gives the driver room to spot it without repositioning fences or landscaping. Placement in the public right of way in Bismarck needs confirming with the city before delivery day. For a walk-through of setup basics, see the porta potty placement guide, and if you are running the trailer through a North Dakota winter, read porta potty in winter first.

Delivery fees run separate from the trailer rate, typically 100 to 500 dollars depending on distance and site access. Crews working out past Mandan, 7.4 miles west, or sites near Lincoln, 7.7 miles southeast, should factor drive time into scheduling. For a broader cost comparison against single units, see restroom trailer rental cost or the general porta potty rental cost page.
Day, week, weekend and full event terms are all available, and weekly rates run lower per day than booking single days back to back. Long construction jobs usually go weekly or monthly; check monthly porta potty rental for how that pricing structure works across unit types.
Some models run self-contained with onboard tanks, others hook to a garden hose and standard outlet. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any workplace restroom, and Bismarck Porta Pros confirms hookup needs during the request a quote call.
Yes. The 2 stall restroom trailer fits smaller crews and tighter budgets, and it needs less clearance to deliver than the 4 stall version.
It works well for guest counts under 150. For larger receptions or add-on shower units, see wedding restroom rental or shower trailer rental for multi-day event support.
Same-day and next-day delivery is often possible depending on the trailer's current location. Call ahead through emergency porta potty rental or contact Bismarck Porta Pros directly to check availability.
