How many people can a 4 stall restroom trailer handle?
Four stalls comfortably cover mid-size gatherings, think 100 to 300 guests over a single event day, more if you're staggering breaks on a job site. Montgomery Porta Pros sizes units against OSHA 1926.51(c), which sets construction toilet ratios starting at one facility per 20 workers. For crews near that threshold, a construction dumpster rental site often pairs a 4 stall unit with standard units to spread out lines. If you're not sure where your headcount lands, how many porta potties do i need walks through the math, and construction site services covers the rest of what a jobsite typically needs alongside it.
What does a 4 stall restroom trailer cost in Montgomery?
Pricing depends on rental length and whether you need same-day delivery or a standing weekly account. Here's where it lands against other trailer options:
| unit | duration | low | typical | high |
|---|---|---|---|---|
| trailer | day | 175 | 800 | 2500 |
| trailer | weekend | 900 | 2000 | 3000 |
| trailer | week | 150 | 1397 | 1650 |
| trailer | event | 2499 | 3500 | 3899 |
A single day rate covers short jobs, but weekly rates make more sense for extended builds. For a full cost breakdown across trailer sizes, see restroom trailer rental cost. If four stalls is more than you need, 2 stall restroom trailer is the smaller option, and 8 stall restroom trailer is the step up for larger festivals. Delivery fees run separately and depend on distance from our Montgomery base; Prattville sits 17.5 miles northwest and Wetumpka runs 18.6 miles north, both within normal service range.
Is a 4 stall restroom trailer ADA accessible?
Not automatically. Most 4 stall trailers are built for standard use, and if your event needs an accessible option, ADA Standards 213.2 requires that at least 5 percent of clustered single-user units be accessible, with never fewer than one. ADA Standards 404.2.3 sets a minimum clear door opening of 32 inches, and ADA Standards 304.3.1 calls for a 60 inch turning circle inside the unit. If your Montgomery event needs a dedicated accessible unit alongside the trailer, ada accessible porta potty covers that separately, and ada restroom requirements explains the full standard. Weddings at outdoor venues around Montgomery often add one ADA unit even when the trailer itself isn't ADA-configured; wedding restroom rental has more on that setup.
Delivery for any trailer needs adequate clearance and a level pad, similar to what a roll-off needs; our roll-off dumpster rental crews look for about 60 feet of straight clearance behind the truck, and trailer delivery follows the same logic. If your site has tight access, mention it when you request a quote so we can plan the approach.
Does a 4 stall trailer need a water and power hookup?
Most units run on an internal freshwater tank and battery power, so no hookup is required for short events. Multi-day rentals in Montgomery sometimes tie into a water spigot if one's available onsite, which cuts down on service visits.
How often does the trailer get serviced during a rental?
ANSI/PSAI Z4.3 sets a baseline of one service visit per week for moderate use, but high-traffic weekend events typically need daily servicing. We schedule around your event timeline, not a fixed default.
Can I rent a 4 stall trailer for a single day?
Yes. Day rentals exist for short events or one-day jobsite needs, though weekly rates offer better value for anything running more than two or three days straight.
What's the difference between standard and deluxe trailer interiors?
Deluxe units add flushable fixtures, sinks, and finished interiors versus a more basic layout. See deluxe flushable porta potty and luxury restroom trailer for the upgraded options if your event calls for it.
Do I need a permit to place a restroom trailer in Montgomery?
Permit rules depend on placement, especially near a public right of way, and that needs confirming with the city before delivery. Check porta potty permit requirements for what to ask about, and our contact team can help you sort it out before your date locks in.
