How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably cover a wedding of 100 to 150 guests, or a job site running two shifts. It splits the load better than a bank of standard porta potty rental units, since sinks are built in rather than separate. For construction crews, OSHA 1926.51(c)(1) still sets the baseline: one toilet facility per 20 workers, scaling up from there as headcount grows. If your site sits closer to 40 or 50 people, run the numbers on our how many porta potties do I need page before you commit to a trailer size. Denver event planners often step up from a 2 stall restroom trailer once guest counts pass the 80 to 100 mark, and step up again to an 8 stall restroom trailer for anything larger. We deliver across Denver and into nearby towns, including a roughly 7.4 mile run to Glendale and 8.2 miles up to Derby, so placement timing depends on where on that map you sit.
What Does a 4 Stall Restroom Trailer Cost in Denver?
Pricing depends on how long you need it and what finish level you want. A basic weekly rate on a comparable deluxe flushable porta potty runs 150 to 290 dollars, but a 4 stall trailer is a different class of unit entirely, built more like a small mobile restroom than a single-stall box.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| weekend | 900 | 2000 | 3000 |
| event (multi-day) | 2499 | 3500 | 3899 |
Delivery is usually a separate line, and our restroom trailer rental cost page breaks that out in more detail. If your event is a single weekend in Denver, the weekend package is usually the better deal over booking day by day. For longer builds, compare against a porta potty monthly rental to see which structure fits your job timeline.
Is a 4 Stall Restroom Trailer ADA Accessible?
Not automatically. A standard 4 stall trailer is built for foot traffic and stairs, so if you need wheelchair access you should pair it with a separate unit or ask about an ADA-configured trailer. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent, and never fewer than one, be accessible, and section 404.2.3 sets a 32 inch minimum clear door opening for that unit. Our ada accessible porta potty page covers standalone options if the trailer itself cannot meet clearance. ADA Standards 405.2 also caps ramp slope at 1:12, something worth checking if your Denver site has any grade to it. For weddings, festivals or golf events where guests expect full access, it is worth reviewing our ada restroom requirements guide before delivery day. Whatever you decide, Denver Porta Pros can walk the site with you and confirm placement fits both the trailer footprint and any accessible unit alongside it.
Beyond the trailer itself, a lot of Denver bookings pair it with other equipment. Construction sites often add a temporary fence rental around the trailer pad, or a light tower rental for early morning access in winter months. Weddings and festivals frequently combine trailers with a handwashing station rental near food service, since 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at washing stations, not sanitizer alone. If your event runs long hours after dark, check our event restroom rental hub for the full setup checklist, and see request a quote to get exact numbers for your date.
How far in advance should I book a 4 stall restroom trailer in Denver?
Book two to four weeks out for weddings or festivals, sooner during peak summer months. Trailers move fast for Denver graduation season and outdoor events. Call contact early if your date is fixed.
Does the trailer need a water and power hookup?
It needs a water source and standard power access. Denver Porta Pros can run a self-contained setup with an onboard tank if hookups aren't available on site; ask when you request a quote.
Can a 4 stall trailer sit on gravel or grass?
Yes, as long as the ground is level and stable enough to keep the trailer from shifting. We check the pad during delivery and use leveling blocks where the surface calls for it.
What is the difference between a 4 stall and an 8 stall trailer?
An 8 stall trailer doubles capacity for larger festivals or multi-day builds. If your guest count sits near 150, review the 8 stall restroom trailer page before booking the smaller unit.
Do I need a permit to place a restroom trailer in Denver?
Placement in the public right of way needs confirming with the city. Check our porta potty permit requirements page, or ask Denver Porta Pros directly when scheduling delivery.
