A 4 stall restroom trailer runs somewhere between about 175 dollars for a short single-day rental and up into the thousands for a full weekend event, depending on how many days you need it and what finish level you pick. Portland Porta Pros sizes each trailer to your headcount, not the other way around.
Four stalls work well for gatherings up to a few hundred guests, spread across a single day. Past that, you start seeing lines, and lines are what push people to rent a bigger unit. If your event runs longer or draws more traffic, look at the 8 stall restroom trailer instead, or compare both against a 2 stall restroom trailer if the guest count is smaller than you think. Portland weddings and backyard events tend to land in the sweet spot for four stalls. So do smaller construction crews who want something nicer than a standard unit on construction sites. ANSI/PSAI Z4.3 sets a baseline service interval of once weekly for up to 10 users over a 40 hour week, which is the standard our crews plan servicing around for longer rentals. If you are unsure where your numbers fall, the how many porta potties do I need guide walks through headcount math before you commit to a trailer at all.

| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| event | 2499 | 3500 | 3899 |
Day rate covers a short rental window. Weekly and event pricing covers multi-day bookings and full weekend coverage, and event-priced trailers usually mean staffed service and a nicer interior finish. For a straight weekend booking outside a formal event package, expect a rate in the 900 to 3000 dollar range depending on trailer condition and delivery distance. Full breakdowns for every trailer size live on the restroom trailer rental cost page, and general restroom trailer rental options are there too if four stalls turns out to be the wrong fit. Delivery trucks need about 60 feet of straight clearance behind the trailer to place it safely, so tell us about driveway slope or tight gates before delivery day, not after the truck shows up.
Not automatically. Most 4 stall trailers are built with standard-width stalls, and ADA Standards section 403.5.1 calls for a 36 inch clear route with a 32 inch clear door opening under section 404.2.3, plus a 60 inch turning circle under section 304.3.1. If you need an accessible stall built into the trailer, say so when you book, or pair the trailer with a standalone ADA accessible porta potty unit set beside it. Under ADA Standards section 213.2, at least 5 percent of clustered single-user units need to be accessible, with a minimum of one, and that rule is worth checking against your total unit count if you are running trailers alongside standard units at the same site. Ground surfaces around the trailer should stay stable and slip resistant per section 302.1, which matters most on gravel lots and unfinished construction sites around Portland.
Portland venues booking trailers for weddings often pair them with wedding restroom rental packages, while festival organizers lean on festival restroom rental planning for multi-day layouts. Crews near Milwaukie, 8.3 miles south of Portland, and Lake Oswego, 12.5 miles south, book the same trailer class for residential jobsites. If your event needs handwashing separate from the trailer's sinks, add a handwashing station rental to the order, and check handwashing requirements if OSHA compliance is part of the plan. For everything else, the portable restroom rental hub covers standard units, and request a quote gets you a number based on your actual dates and site.
Depends on guest count and event length. Four stalls generally cover events up to a few hundred guests over a single day. Longer events or bigger crowds push you toward the 8 stall restroom trailer. Check the how many porta potties do I need guide for exact ratios.
Most trailers run lighting, water pumps and climate control off onboard power or a generator, but some setups want a dedicated hookup. Ask about temporary power pole options if your site has no existing service nearby.
Weekends and wedding season book out fastest. Reserve a few weeks ahead for a standard weekend, and earlier for peak summer dates. Delivery clearance and site access get confirmed before the truck loads.
Yes. Many Portland events pair one standard porta potty rental or two near parking or overflow areas so the trailer stays reserved for guests closer to the main event space.
A 4 stall trailer has running water, sinks and flushing fixtures across four private stalls. A deluxe flushable porta potty is a single-unit step up from standard, without the multi-stall trailer footprint or plumbing setup.
