How many people can a 4 stall restroom trailer serve?
A 4 stall unit works well for gatherings in the 100 to 250 person range over a single day, or a job site crew running two shifts. On construction jobs, OSHA 1926.51(c) sets the baseline: one toilet facility for 20 workers or fewer, scaling up from there, so a 4 stall trailer often replaces four or five separate porta john rental units without the line at each door. For weddings and events, guest flow matters more than raw counts. Check our how many porta potties do I need guide before booking, and compare against a smaller 2 stall restroom trailer if your headcount runs lighter. Bigger productions in Scottsdale sometimes step up to an 8 stall restroom trailer instead, especially for multi-day festivals.
What does a 4 stall restroom trailer cost in Scottsdale?
| duration | low | typical | high |
|---|---|---|---|
| day | $175 | $800 | $2,500 |
| week | $150 | $1,397 | $1,650 |
| weekend | $900 | $2,000 | $3,000 |
| event rate | $2,499 | $3,500 | $3,899 |
Delivery adds on top of the trailer rate, and most delivery fees in Scottsdale fall between $100 and $500 for a single day, with weekly delivery running lower per visit. See the full breakdown on our restroom trailer rental cost page, or compare against a basic porta potty rental cost if you're weighing trailer against standard units. A weekend event booking sits closer to the top of that band because setup and teardown both happen on short notice. For longer commitments, our monthly porta potty rental page covers standard units, though trailers are usually booked by the day, week, or event rather than the month.
Where can a 4 stall restroom trailer be placed on site?
Placement needs a level, stable surface, per ADA Standards section 302.1, which calls for ground that's firm and slip resistant. Delivery crews need clearance to position the trailer and hook up service, similar to how a roll-off dumpster rental needs about 60 feet of straight clearance behind the truck. If you want the unit ADA accessible, the accessible route needs a minimum 36 inch clear width under ADA Standards section 403.5.1, and any door opening on the accessible stall needs at least 32 inches clear per ADA Standards section 404.2.3. We also handle placement for ADA accessible porta potty needs on the same site if your event requires both trailer and standard units. Setting up in the public right of way in Scottsdale needs confirming with the city before delivery; we don't guess at that. For events near Fountain Hills, about 16.6 miles southeast of Scottsdale, or Paradise Valley, roughly 15.4 miles southwest, we run the same trailer stock and delivery process. Our porta potty placement guide covers ground surface, slope, and clearance in more detail, and pairs well with a look at temporary fence rental if you need to secure the area around the trailer. For handwashing separate from the trailer's built-in sinks, see handwashing station rental.
Does the trailer include its own water and power?
Yes, a 4 stall trailer runs on a self-contained water and holding system, no hose bib or septic tie-in required. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, and the trailer's onboard tank satisfies that on job sites. Power needs are minimal; most units run on standard household voltage or a small generator, unlike the heavier draw covered on our temporary power pole page.
How often does the trailer get serviced during a multi-day rental?
Servicing follows a schedule built around usage, not a fixed calendar date. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users over a 40 hour week, and a 4 stall trailer under heavy weekend use often needs a mid-event top-off. We track tank levels and schedule accordingly for anything booked through event restroom rental.
Can I rent a 4 stall trailer for a wedding in Scottsdale?
Yes, it's one of our most requested setups for Scottsdale weddings. See wedding restroom rental for finishes and layout options, or step up to a luxury restroom trailer if you want upgraded interiors for a formal reception.
Do I need a permit to place a restroom trailer in Scottsdale?
That depends on where the trailer sits and how long it stays. Placement on private property is usually simple; placement near a street or right of way needs confirming with the city first. Check porta potty permit requirements before you finalize a site plan.
What's the difference between a restroom trailer and a deluxe porta potty?
A restroom trailer offers multiple stalls, sinks, and climate control in one unit; a deluxe flushable porta potty is a single-stall flushable unit at a lower price point. Choose the trailer for higher headcounts or upscale events, the deluxe unit for smaller gatherings on a tighter budget.
