A 4 stall restroom trailer serves roughly 100 to 150 guests over a single event day, and Spokane Valley Porta Pros prices this size between the trailer weekend rate and a full weekly booking depending on how long you keep it. It fits weddings, festivals and multi-day construction jobs.
Trailer pricing depends on duration more than anything else. A single day runs at the low end of the trailer rental cost range, a weekend climbs higher, and a full week sits well above that because the unit is tied up on your site the whole time. Multi-day events in Spokane Valley, like a golf outing or a wedding restroom rental, usually land in the weekend band. Larger festivals booking a full week should expect the top of that range. Compare against a smaller 2 stall restroom trailer if your guest count is under 100, or step up to an 8 stall restroom trailer for anything over 200.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| weekend | 900 | 2000 | 3000 |
| week | 150 | 1397 | 1650 |
| event | 2499 | 3500 | 3899 |
Delivery is billed separately and depends on distance from our yard. If your site sits toward Liberty Lake, 7.0 miles east of Spokane Valley, or Millwood, 4.6 miles northwest, tell us the address up front so we can quote delivery accurately alongside the restroom trailer rental itself.
Four private stalls, running water, and a layout built for steady traffic rather than a single-unit line. This is a step above a standard porta potty rental or even a deluxe flushable porta potty: guests get flushing fixtures and a sink instead of a single hand sanitizer pump. If you need an accessible option alongside the trailer, ADA Standards section 213.2 requires that where portable units are clustered, at least 5 percent, and never fewer than one, must be accessible, so pair the trailer with an ADA accessible porta potty rather than assuming the trailer itself covers that requirement. We also stock handwashing station rental units and portable sink rental add-ons if your event needs more than the trailer's built-in sinks, since 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device at any washing facility, not sanitizer alone.
Placement comes down to ground and access. The trailer needs a reasonably level, firm surface, consistent with the slip-resistant, stable ground called for under ADA Standards section 302.1, and enough clearance for our truck to back in and level the unit. If you're also renting a roll-off dumpster rental for the same job, remember a roll-off delivery needs about 60 feet of straight clearance behind the truck, so plan both drop points before delivery day. For construction sites running the trailer alongside crews, OSHA 1926.51(c) sets the toilet ratio at one facility per 20 workers or fewer, which is worth checking against your headcount using our how many porta potties do I need guide. Check our porta potty placement guide for driveway width and slope details before we arrive, and review OSHA portable toilet requirements if this is a jobsite rather than a private event.
Comfortably 100 to 150 guests across a single event day, more if the event runs shorter hours or guests arrive in waves rather than all at once. For weddings and festivals in Spokane Valley, we size against your headcount and hours, not just guest count; see festival restroom rental for event-specific sizing guidance.
Placement in the public right of way needs confirming with the city before delivery. We do not guess at permit rules; check our porta potty permit requirements page and confirm directly with Spokane Valley before your event date locks in.
Yes, day rentals exist inside our trailer rental cost range, though most weddings and multi-day builds book a weekend or full week instead since delivery and pickup logistics favor a longer hold.
Guest capacity, mainly. A 4 stall handles up to about 150 people; an 8 stall restroom trailer roughly doubles that. Choose based on your headcount and event length, not just budget.
Most units run self-contained, but larger luxury restroom trailer configurations may want an outlet nearby. Ask about a temporary power pole if your site has no existing power source.
