How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably covers a mid-size event or a job site crew without a long line forming. North Charleston Porta Pros builds this into most quotes for gatherings under a few hundred guests, and it works well for wedding restroom rental bookings where guests expect something nicer than a standard unit. If you are running a bigger festival, step up to the 8 stall restroom trailer instead. Construction sites in North Charleston lean on OSHA 1926.51(c) for guidance on toilet ratios per worker count, and a 4 stall unit often satisfies that math for crews in the 40 to 80 person range. Smaller two-person or subcontractor crews are usually better served by the 2 stall restroom trailer, which costs less to deliver and park. Pair either trailer with a handwashing station rental if the scope includes exterior painting, since OSHA 1926.51(f)(1) requires washing facilities specifically where paints, coatings, herbicides or insecticides are in use.
What Does a 4 Stall Restroom Trailer Need for Setup?
Every trailer needs level, stable ground and a clear approach for the delivery truck. North Charleston Porta Pros checks the site before drop-off, the same way we would for a roll-off dumpster rental or a storage container rental, because trailers and roll-offs both need real clearance to back in. ADA Standards section 405.2 caps ramp slope at 1:12, which matters if your stalls include an accessible unit; ADA Standards section 213.2 requires at least one accessible unit in a cluster of single-user toilets, and never fewer than one no matter how small the group. Ground should meet ADA Standards section 302.1 for a stable, slip resistant surface if guests will use a ramp. For events near Ladson, 9.3 miles north of North Charleston, or Goose Creek, 9.7 miles northeast, we've handled the same setup checks on tighter lots. If your site cannot host a trailer, our standard porta potty rental or deluxe flushable porta potty options need far less room. Check our full porta potty placement guide before you commit to a spot.
Is a 4 Stall Restroom Trailer Worth It Over Multiple Porta Potties?
For weddings, corporate events and multi-day builds, yes, a trailer usually wins on comfort and perception. Guests get real sinks, mirrors and climate control that a portable toilet rental can't match. North Charleston Porta Pros quotes both side by side so you can compare. 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at washing stations, which trailers include standard, unlike a hand sanitizer station alone. For construction crews still deciding, our porta john rental page breaks down per-worker costs, and our OSHA portable toilet requirements guide walks through 1926.51(c) ratios in full. If budget is the deciding factor, run the numbers against our restroom trailer rental cost page before booking.

How far in advance should I book a 4 stall restroom trailer?
Two to four weeks is safe for most events; wedding season in North Charleston fills fast. For events near Summerville, 12.7 miles northwest, or Sangaree, 14.1 miles northwest, book earlier if the date lands on a weekend. Call North Charleston Porta Pros to confirm the date.
Can a 4 stall restroom trailer be used for construction sites?
Yes, and it's common on longer builds where crew comfort matters. OSHA 1926.51(c) sets the toilet ratio you need to hit. Pair it with our construction site services page for dumpsters, fencing and power in one plan.
Does the trailer need a hookup?
Most units run self-contained with onboard water and holding tanks, no hookup required. Ask about generator needs for lighting and climate control. See temporary power pole options if your site needs backup power.
What is the door width on these trailers?
ADA-compliant stalls meet ADA Standards section 404.2.3, a 32 inch minimum clear opening. Standard stalls are close to that width too. Ask for exact measurements when you request a quote.
