How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls is the sweet spot between a 2 stall restroom trailer and the bigger 8 stall restroom trailer. It works for a wedding of 150 guests over a Saturday, or a job site running two shifts. OSHA 1926.51(c)(1) sets construction toilet ratios: one facility for 20 workers or fewer, then one toilet seat and one urinal per 40 workers up to 200. On a crew site, four stalls covers a decent-sized workforce without stacking up lines. For events, pair it with event restroom rental planning so flow matches your guest count, and check how many porta potties do i need if you are mixing trailer stalls with standard units. Carson City venues with weekend crowds lean toward the 4 stall size because it splits by gender without the footprint of an 8 stall unit.
What Does a 4 Stall Restroom Trailer Cost in Carson City, NV?
Pricing depends on rental length and finish. A day rate for a trailer this size runs from the low end near 175 dollars for a bare-bones day unit up through much higher weekend and multi-day figures once you add flush systems, climate control and finish trim. Full weekly rentals sit near the middle of the market. Here is the general shape:
| Duration | Typical Range |
|---|---|
| Day | 175 - 2500 |
| Weekend | 900 - 3000 |
| Week | 150 - 1650 |
| Event package | 2499 - 3899 |
A delivery fee applies separately, and weekly delivery charges run lower than day or weekend delivery because the truck makes fewer trips. See restroom trailer rental cost for a fuller breakdown, or check porta potty rental cost if you are comparing against standard units instead. For longer jobs, monthly porta potty rental terms sometimes beat booking a trailer week by week.
Is a 4 Stall Trailer ADA Accessible?
Not automatically, and this matters for public events. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent be accessible, with a minimum of one. A 4 stall trailer usually needs a dedicated accessible stall built to that same standard, meaning a 36 inch clear route per ADA Standards section 403.5.1, a 32 inch door per ADA Standards section 404.2.3, and a 60 inch turning circle inside per ADA Standards section 304.3.1. If your event or job site in Carson City draws public foot traffic, ask about an ADA accessible porta potty add-on rather than assuming the trailer covers it. Ramp access also matters: ADA Standards section 405.2 caps ramp slope at 1:12, which affects where the trailer can sit on uneven ground. Review ada restroom requirements before you finalize a site plan, especially for venues near Indian Hills, 6.8 miles southwest of Carson City, where lot grading varies.
Setup also needs level, firm ground. ADA Standards section 302.1 calls for stable, slip-resistant surfaces, which is one reason our crew scouts the pad before delivery day rather than guessing from photos.
What is the difference between a 4 stall and an 8 stall trailer?
Four stalls handles roughly half the traffic of an 8 stall unit, and costs less to rent and deliver. If your guest count tops 200 or your job site runs three shifts, step up to the 8 stall restroom trailer. For anything under 150 people, four stalls is usually plenty and easier to place on a tight lot.
Do I need permits for a restroom trailer in Carson City?
Placement in the public right of way needs confirming with the city before delivery day. On private property it is more straightforward. Check porta potty permit requirements or dumpster permit requirements for the general pattern, and ask us directly when you book through request a quote.
Can a 4 stall trailer run without a water hookup?
Yes, most units carry their own fresh water and holding tanks, similar in concept to the 60 to 70 gallon tank on a standard portable unit, just scaled up across four stalls. That makes it workable at remote sites without hose access, unlike a holding tank rental setup that needs periodic pump service.
How much clearance does delivery need?
Plan for roughly 60 feet of straight clearance behind the delivery truck, the same clearance guideline used for roll-off dumpster rental drops. Tight driveways or alley access in older Carson City lots sometimes need a site visit first.
Should I add a handwashing station separately?
If the trailer's built-in sinks are limited or you expect heavy food service nearby, yes. 29 CFR 1910.141(d)2 requires soap and towels or a hand-drying device at washing facilities, and a separate handwashing station rental covers overflow demand at busy events without straining the trailer's own fixtures.
