A 4 stall restroom trailer gives you four private, flushing stalls for events or job sites where a couple of standard units will not cut it. Rental runs from a single day up to a full week or month, and Commerce City Porta Pros sizes the unit to your headcount before delivery.
A 4 stall trailer works well for gatherings between 100 and 300 guests over a few hours, or a mid-size construction crew across a full shift. If you are unsure where your event lands, the how many porta potties do I need guide walks through headcount math, and construction crews should check OSHA portable toilet requirements against OSHA 1926.51(c), which sets ratios by worker count. Weddings and family events in Commerce City tend to like the extra privacy over a bank of standard porta potty rental units. For anything larger, look at the 8 stall restroom trailer instead, and for smaller backyard jobs the 2 stall restroom trailer may be plenty. If part of your guest list needs a compliant unit, pair the trailer with an ADA accessible porta potty, since ADA Standards section 213.2 calls for at least one accessible unit in a cluster.

Pricing depends on rental length and how far the trailer travels to reach you. Below is what the market runs for restroom trailers generally, since a 4 stall unit sits inside these bands.
| Duration | Typical Range |
|---|---|
| Day | $175 - $2,500 |
| Week | $150 - $1,650 |
| Event (multi-day) | $2,499 - $3,899 |
A weekend booking usually lands between $900 and $3,000 depending on stall count and add-ons. Delivery adds a separate fee, and full details live on the restroom trailer rental cost page. If your event only needs one weekend, compare against the porta potty rental per day numbers before deciding between a trailer and standard units. Longer builds in Commerce City often shift to the monthly porta potty rental rate instead of booking week to week. For the full cost breakdown across all unit types, see porta potty rental cost.
The trailer needs a level pad and clear access for the delivery truck. Roll-off and trailer deliveries generally need about 60 feet of straight clearance behind the truck, so a driveway, alley, or open lot works best. Inside the trailer, ADA Standards section 405.2 caps ramp slope at 1:12 and section 404.2.3 sets a 32 inch minimum door width for any accessible stall, so check ground conditions before delivery day. The porta potty placement guide covers surface and clearance questions in more depth. If you are also running a fenced perimeter around the event, a temporary fence rental keeps foot traffic routed toward the trailer instead of wandering the site. Job sites pairing the trailer with a dumpster should also review dumpster permit requirements, since placement in the right of way needs confirming with the city and no blanket rule applies statewide.
Commerce City venues booking for weddings or festivals should also look at wedding restroom rental or festival restroom rental for event-specific add-ons like attendants and lighting. Construction crews building out a site can bundle the trailer with construction site services, roll-off dumpster rental, and a handwashing station rental to keep water and waste in one delivery. Anyone comparing basic units first should start at portable restroom rental or the main Porta Potty Rental in Commerce City, CO hub page.
Book as early as you can once your date is set, especially for weekend events. Trailers move fast during wedding and festival season, and Commerce City sits close enough to Brighton, about 9.5 miles north, that regional demand overlaps.
Most units run on internal battery or a small generator, but climate control and lighting draw more. Ask about power needs when you book so the crew brings the right setup for your site.
It needs a firm, level surface. ADA Standards section 302.1 requires stable, firm, slip resistant surfaces, so gravel that shifts or soft grass after rain may need matting first.
Standard service follows roughly one visit per week per the ANSI/PSAI Z4.3 baseline interval, but heavy-use events usually get serviced daily or every other day instead.
A 4 stall trailer has flushing toilets, sinks, and climate control inside one enclosed unit. Standard units are single-occupant and cheaper per unit, covered on the porta john rental page.
