How many stalls do I actually need?
That depends on headcount and how long people stand in line. For a wedding of 200 or a festival day, 8 stalls split by gender keeps lines moving; smaller gatherings do fine with a 2 stall restroom trailer or a 4 stall restroom trailer instead. Construction crews should size to OSHA 1926.51(c), which calls for 1 toilet per 20 workers on a job site, but events don't run on that ratio. Our porta potty rental checklist walks through headcount math, and our guide on how many porta potties you need covers the same question for standard units if a trailer is more than the job calls for. If you're weighing a step down, the standard porta potty rental page and portable toilet rental page both cover single-unit pricing for comparison.
What does an 8 stall unit need on site?
Space and power, mainly. Delivery needs roughly 60 feet of straight clearance behind the truck, same clearance a roll-off dumpster rental needs, so tell us up front if the driveway is tight or if you're near Camas, 11.7 miles east of Vancouver, where some venue lots are gravel and sloped. Ground should be reasonably level and firm, similar to the stable, slip-resistant surface standard under ADA Standards 302.1, even though a self-contained trailer isn't a fixed-facility ADA install. If your event needs a dedicated accessible unit alongside the trailer, pair it with an ADA accessible porta potty, which follows a 60 inch turning circle under ADA Standards 304.3.1 and a 32 inch clear door opening under ADA Standards 404.2.3. Most 8 stall trailers also want a 30 amp or better circuit; we'll confirm exact draw when we quote. If you need general lighting for an evening event, a light tower rental pairs well, and a temporary power pole covers sites without existing service.
Where can I place it and do I need a permit?
Placement in the public right of way needs confirming with the city, so check with Vancouver before locking a curbside spot; on private lots and venue grounds it's simpler. Our porta potty placement guide and porta potty permit requirements page cover the groundwork either way. Weddings near Battle Ground, 11.7 miles north, or ranch venues out toward Orchards, 6.4 miles northeast, often have their own site rules, so ask the venue coordinator before we deliver. For handwashing alongside the trailer, soap and towels or a hand-drying device are required under 29 CFR 1910.141(d)(2); a handwashing station rental or portable sink rental satisfies that cleanly. Larger festival grounds sometimes pair the trailer with a temporary fence rental to control flow into the restroom area.
Table: 8 stall trailer vs other rental durations
| duration | typical range |
|---|---|
| day | 175 to 2,500 |
| weekend | 900 to 3,000 |
| week | 150 to 1,650 |
| multi-day event | 2,499 to 3,899 |
Day rates on this table span a wide range because a single day rate can mean a small trailer or a large one; ask us which bracket your headcount falls into. For comparison shopping across unit types, see restroom trailer rental cost and the general porta potty rental cost page.
Does the trailer need a water hookup?
Not always. Most units carry an onboard fresh water tank, and OSHA 1926.51(a)(1) requires potable water be supplied at any workplace using the trailer for crew sanitation. For events, we fill before delivery so you don't need a spigot on site.
Can I upgrade to something nicer than a standard trailer?
Yes. Our luxury restroom trailer and deluxe flushable porta potty options add finishes like real sinks and climate control, priced separately from the standard 8 stall unit.
What if my event needs showers too?
We rent a separate shower trailer rental unit for that. It pairs with the restroom trailer for multi-day festivals or disaster response work under our disaster relief sanitation service.
Is delivery included in the price?
No, delivery is quoted separately based on distance and site access. Ask when you request pricing so there's no surprise on invoice day.
How far in advance should I book for a wedding?
Book as soon as your date and headcount are set, especially for peak season weekends. See our wedding restroom rental page or the broader event restroom rental page for lead-time guidance.
