What Is a 4 Stall Restroom Trailer?
It is a towable trailer split into four private restroom compartments, each with its own door and lock. Compare that to a bank of standard porta potty rental units lined up along a fence, and the difference is obvious: real doors, real sinks, climate control in most builds. Detroit Porta Pros sets these up for weddings, contractor crews, and street festivals across the city. Door openings need to clear ADA Standards section 404.2.3, which sets a 32 inch minimum clear width, and any accessible route to the unit should hold to the 36 inch minimum under ADA Standards section 403.5.1. If your event or job site needs one accessible stall in the mix, check the ADA accessible porta potty page before you book. Most 4 stall units pair well with a handwashing station rental nearby, since sink space inside the trailer fills fast during peak hours. For sites weighing trailer against standard units, the restroom trailer rental overview breaks down when each makes sense.
How Much Does a 4 Stall Restroom Trailer Cost in Detroit?
| duration | low | typical | high |
|---|---|---|---|
| day | $175 | $800 | $2,500 |
| week | $150 | $1,397 | $1,650 |
| event | $2,499 | $3,500 | $3,899 |
Day rate spans wide because a bare-bones unit and a fully finished luxury restroom trailer rental sit on opposite ends of that range. Weekend events near Hamtramck, 3.3 miles east of downtown Detroit, often land closer to the weekend band than the flat day rate, since weekend pricing runs as its own tier. Multi-day contractor jobs usually book the week rate instead of stacking day rates, since a week rental beats seven single days on cost. For a full breakdown by unit and term, see restroom trailer rental cost. Delivery adds a separate line, typically in the $100 to $500 day range or $120 to $420 for a month-long placement, and that fee scales with how far the trailer travels from our Detroit yard. Sites out toward Livonia, 16.0 miles west, or Troy, 18.2 miles north, should confirm delivery cost before locking a date.
How Many People Can a 4 Stall Unit Handle?
OSHA 1926.51(c)(1) sets the baseline for construction crews: one toilet facility for 20 workers or fewer, then additional seats as headcount climbs past that. Four stalls comfortably covers a crew in the 40 to 60 range for most shifts, though tight schedules or heavy lunch-hour overlap can still create a line. For events, the ANSI/PSAI Z4.3 service standard treats one unit per 10 users across a 40 hour week as the baseline service interval, which is a good starting ratio for wedding and festival headcounts too. If you are not sure your guest count or crew size fits four stalls, the how many porta potties do I need guide walks through the math, and OSHA portable toilet requirements covers the construction-site rules in full. Larger builds sometimes step up to an 8 stall restroom trailer instead, while smaller crews or backyard projects tend to fit a 2 stall restroom trailer just fine.
How far in advance should I book a 4 stall trailer?
Two to four weeks out is safe for most Detroit dates. Wedding season and festival weekends near Redford, 11.7 miles west, book faster. If your date is inside a week, call first; we can often still place a unit, but options narrow fast.
Does a 4 stall trailer need a generator?
Some builds run on standard household power, others need a generator or a hookup we can arrange. Tell us your site's power situation when you request a quote and we will match the trailer to what you have. Ground fault protection matters here too, per OSHA 1926.404(b)(1)(ii).
Can I place a 4 stall trailer on a residential street in Detroit?
Placement in the public right of way needs confirming with the city before delivery. Private driveways and lots are simpler. See porta potty placement guide and porta potty permit requirements for what to check first.
What is the difference between a 4 stall and a shower trailer?
A 4 stall unit covers restrooms only. A shower trailer rental adds bathing stalls, which disaster relief crews and multi-day event staff often need on top of restrooms. Many sites rent both together.
Do I need a permit for a 4 stall trailer at an event?
Sometimes, depending on the venue and street use. This has not been verified against current Detroit code, so confirm with the city before your event date. Our FAQ page and request a quote form are both good next steps.
