A 4 stall restroom trailer from Durham Porta Pros gives four private stalls, running water and climate control for events or job sites running 100 to 300 people a day. Rental terms range from a single day up to a full week or event weekend, priced by duration. It fits weddings, festivals and multi-week construction jobs across Durham.
It's a trailer unit with four enclosed, flushable restrooms, sinks with running water and interior lighting, built for jobs where a standard portable toilet rental isn't enough presence or comfort. Compare it against the 2 stall restroom trailer for smaller gatherings, or the 8 stall restroom trailer once headcount climbs past a few hundred. Durham Porta Pros sets these for weddings, corporate events and long-duration builds where crews want something closer to a real bathroom than a porta john rental. Compared to a basic standard porta potty rental, the trailer needs a level pad and clearance for delivery, similar to what a roll-off dumpster rental needs behind the truck. Ask about a luxury restroom trailer upgrade if you want finishes closer to indoor plumbing. For accessibility, pair it with a separate ADA accessible porta potty, since most 4 stall trailers are not ADA compliant units on their own, and ADA Standards section 213.2 requires that clustered single-user units include at least one accessible unit.
Pricing depends on how long you need it and whether it's a weekend event or a multi-week rental. Check full detail on the restroom trailer rental cost page or the general restroom trailer rental overview before booking.
| Duration | Typical Range |
|---|---|
| Day | $175 - $2,500 |
| Week | $150 - $1,650 |
| Weekend | $900 - $3,000 |
| Multi-day event | $2,499 - $3,899 |
Longer construction jobs often pencil out closer to the weekly rate than paying day by day. If your event runs closer to a shower need, look at the shower trailer rental option instead. For raw cost comparison against standard units, see porta potty rental cost or porta potty rental per day.
Placement needs a flat pad, road access for delivery and, on public property, confirmation with the City of Durham on right-of-way rules, since specific permit language isn't published here. Review the porta potty placement guide and porta potty permit requirements before finalizing a site plan. On construction sites, OSHA 1926.51(c) sets the baseline for how many toilet facilities a crew needs, and the trailer can count toward that if stall numbers cover headcount. For agricultural sites, OSHA 1928.110 requires field sanitation facilities within a quarter mile walk of hand-labor employees. If the job also involves painting, coatings or pesticide work, OSHA 1926.51(f)(1) requires washing facilities for those specific tasks. Durham event venues and job sites both need roughly 60 feet of clear straight approach for delivery trucks, the same clearance a roll-off dumpster rental needs. Homes in nearby Chapel Hill, 9.6 miles southwest of Durham, and Morrisville, 13.5 miles south, fall inside our regular delivery routes alongside Durham proper.

Four stalls comfortably support 100 to 300 guests over a single event day, depending on flow and bar service. For ongoing construction crews, OSHA 1926.51(c) sets ratios by headcount, so check the how many porta potties do I need guide to confirm stall count against your crew size.
It runs best with a nearby water source and standard power, though many units carry onboard tanks. Ask Durham Porta Pros about hookup options when you request a quote; we'll confirm what your specific unit needs on site.
Yes, though most homeowners find a home renovation porta potty or single standard porta potty rental fits smaller crews better and costs less over a multi-week job.
