What Is a 4 Stall Restroom Trailer?
It's a towable trailer with four separate restroom compartments, each with its own door, sink, and flushing toilet, wired and plumbed as one unit. Compare that to a single standard porta potty rental, which is about 44 by 48 inches on the ground with a 60 to 70 gallon tank and no sink built in. A 4 stall trailer works better for events pulling steady traffic, like a wedding reception or a weekend festival near downtown Avondale, because guests move through four lines instead of one. Builders working multi-week jobs also like it over a bank of porta john rental units because crews get real fixtures and less odor complaint. If you're deciding between a trailer and standalone units, the porta potty placement guide and the how many porta potties do i need page both walk through the math for your headcount. For bigger crowds, step up to an 8 stall restroom trailer; for a tighter footprint, the 2 stall restroom trailer does the same job smaller.
How Much Does a 4 Stall Restroom Trailer Cost in Avondale?
Trailer pricing runs in a wide band because "restroom trailer" covers everything from a bare-bones unit to a climate-controlled luxury restroom trailer. Here's how the numbers typically break out:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Multi-day event | $2,499 | $3,500 | $3,899 |
Delivery adds a separate line, generally 100 to 500 dollars for a single day and 50 to 150 dollars a week, since the truck only makes the trip once either way. For a full breakdown by trim level, see restroom trailer rental cost or the general porta potty rental cost page if you're weighing a trailer against standard units. Weekend and single-day event rates run higher per day than a full week because the crew still has to deliver, set, and pull the unit on a short turnaround.
Where Can a 4 Stall Restroom Trailer Be Placed on My Site?
It needs level, stable ground and enough clearance for the delivery truck to back in and level the trailer, similar to the 60 feet of straight clearance a roll-off dumpster rental truck needs behind it. ADA Standards section 405.2 caps ramp slope at 1:12, and section 403.5.1 calls for a 36 inch clear path, so if you need accessible entry, say so up front and ask about pairing with an ada accessible porta potty as backup. Placement in the public right of way in Avondale needs confirming with the city before delivery day; check the porta potty permit requirements or dumpster permit requirements pages for what that process generally covers, then confirm with Avondale directly. Goodyear, about 2.6 miles southwest of Avondale, and Litchfield Park, roughly 26.6 miles north, fall inside our regular delivery range, along with Tolleson and Buckeye further out.
How many people can a 4 stall trailer serve?
OSHA 1926.51(c)(1) sets construction ratios at 1 toilet for 20 workers or fewer, scaling up from there. A 4 stall trailer comfortably covers a crew in that range or an event of a few hundred guests over a few hours, depending on turnover. For exact headcounts, run the numbers through how many porta potties do i need.
Does the trailer need a power hookup?
Most units run lighting and pumps off an onboard battery or a standard outlet; heavier trim levels may want a dedicated circuit. Ask about combining with a temporary power pole or light tower rental if your Avondale site has no power source nearby.
Can I rent a 4 stall trailer for a wedding?
Yes. It's one of the more common uses alongside the wedding restroom rental and event restroom rental pages, and most weekend wedding bookings fall in the weekend pricing band above.
What's the difference between a 4 stall and a luxury trailer?
Stall count is about capacity; luxury trim is about finish. A luxury restroom trailer can come in 4 stall configuration with upgraded fixtures, climate control, and sound systems, priced at the higher end of the day and event bands.
Do I need handwashing stations too?
Each stall has its own sink, but high-traffic events sometimes add standalone units anyway. Check handwashing station rental or 29 CFR 1910.141(d)(2), which requires soap and towels or a hand dryer, not sanitizer alone, at any washing station on site.
