How many people can a 4 stall restroom trailer handle?
Four stalls move a crowd faster than any single-unit setup, which is why we point people toward this size once guest counts or crew counts climb past what a standard porta potty rental can absorb comfortably. ANSI/PSAI Z4.3 sets a baseline service interval of once weekly for up to 10 users over a 40 hour week for portable sanitation generally, and a four-stall unit spreads that demand across four separate flush stations instead of stacking everyone behind one door. For construction crews, OSHA 1926.51(c)(1) ties facility counts to headcount: one toilet for 20 workers or fewer, then a step up in ratio from there. If your crew count is climbing, check how many porta potties you need before you commit to a size. Events run different math than jobsites, and our event restroom rental guide breaks that down further.
What does a 4 stall restroom trailer cost in Kennewick?
Pricing depends on trailer grade, rental length and delivery distance across Kennewick. A basic day rate for a restroom trailer starts around 175 dollars, while multi-day and weekend event bookings climb well past that once you add finish level and stall count.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| weekend | 900 | 2000 | 3000 |
| event (multi-day) | 2499 | 3500 | 3899 |
Delivery is billed separately and depends on distance and access. A full breakdown of what drives cost, including the difference between a basic trailer and a nicer finish, sits on our restroom trailer rental cost page. If four stalls is more than you need, look at the 2 stall restroom trailer instead, and if you need more, the 8 stall restroom trailer covers bigger crowds. Our general porta potty rental cost and porta potty rental per day pages cover single-unit pricing for comparison.
Is a 4 stall restroom trailer accessible?
Not automatically. Standard four-stall trailers are built for speed and stall count, not wheelchair access, so if the site needs an accessible restroom you should plan for a dedicated unit alongside it. ADA Standards section 213.2 requires that where single-user portable units are clustered, at least 5 percent must be accessible, with a minimum of one unit regardless of cluster size. That accessible unit needs a 36 inch clear route per ADA Standards section 403.5.1, a 32 inch door opening per section 404.2.3, and a 60 inch turning circle inside per section 304.3.1. Our ADA accessible porta potty page covers unit specs, and ADA restroom requirements walks through the full standard. For a nicer finish without the accessibility build-out, the luxury restroom trailer and deluxe flushable porta potty pages are worth a look. If your event needs showers too, see our shower trailer rental page.
Delivery trucks need roughly 60 feet of straight clearance behind the trailer to place it safely, so tight lots in downtown Kennewick or older residential driveways sometimes need a site visit first. Crews working near Finley, about 7.6 miles east of Kennewick, or out toward Richland, 11.4 miles northwest, should mention distance when requesting a quote so delivery is priced accurately. Our service areas page lists coverage across the region, and our porta potty rental in Kennewick hub page ties everything together.
How long does delivery and setup take?
Most trailer deliveries in Kennewick are scheduled same week, sometimes same day for urgent jobs. Setup itself takes under an hour once the truck is positioned. Book earlier for weekend events since trailer availability tightens around peak wedding and festival season.
Does a 4 stall restroom trailer need a water and power hookup?
It depends on the model. Some trailers run self-contained with onboard tanks, others need a nearby water source and standard outlet. Ask when you request a quote so we can match the trailer to your site's hookups.
Can I rent a 4 stall restroom trailer for a single day?
Yes, day rentals are available, though most multi-day events and weddings book by the weekend or week rate since it costs less per day than booking single days back to back.
How often does the trailer get serviced during a multi-day rental?
Service frequency depends on guest count and rental length. Our septic pumping service page covers how tank pump-outs work for larger events needing mid-rental service.
What is the difference between a restroom trailer and a portable restroom?
A trailer offers multiple enclosed stalls with a shared entrance, while a portable restroom rental is a single stand-alone unit. Trailers suit weddings and larger crews; single units suit smaller jobsites and tight budgets.
