How many people can a 4 stall restroom trailer handle?
Four stalls comfortably cover a wedding, company picnic, or short construction push in Auburn without a line forming at every break. Think of it as roughly one stall per 20 to 30 guests over a several hour event, similar to the crew ratio OSHA 1926.51(c)(1) uses for construction toilets: one facility per 20 workers on a job site. If your headcount runs higher, step up to the 8 stall restroom trailer instead. Smaller gatherings do fine with a 2 stall restroom trailer, which costs less to deliver and haul. Auburn Porta Pros sizes the trailer to the guest count and the hours it needs to run, not just the square footage of the venue. A trailer parked near a job trailer or a beer garden also needs a stable, level pad, so confirm ground conditions before delivery day. That single planning step avoids most complaints once the event starts.
What comes inside a 4 stall restroom trailer?
Expect flush toilets, sinks with running water, and interior lighting in each stall, a step up from the fold-down counters in a deluxe flushable porta potty. Doors and interior clearances follow accessibility guidance where a unit is marked accessible: ADA Standards section 404.2.3 sets a 32 inch minimum clear door opening, and section 403.5.1 calls for a 36 inch clear route to the unit. If your event needs a fully accessible stall, ask about an ADA accessible porta potty or a trailer built to those same clearances. Handwashing setups meet 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device at any station, not hand sanitizer alone. Pair the trailer with a standalone handwashing station rental if your layout puts food service far from the restrooms.
Where does Auburn Porta Pros deliver 4 stall restroom trailers?
Auburn Porta Pros delivers across Auburn and into nearby communities: Sumner sits 8.9 miles south, Covington is 9.2 miles northeast, Edgewood runs 9.5 miles southwest, Bonney Lake is 10.0 miles south, and Des Moines is 12.1 miles northwest. Delivery fees for any trailer or unit type land between $100 and $500 a day depending on distance and site access, and weekly delivery runs lower per visit than a single day trip. A roll-off dumpster rental or temporary fence rental booked for the same event can often share a delivery window and cut down on separate truck trips to the site.

Frequently asked questions
How far in advance should I book a 4 stall restroom trailer?
Book 2 to 4 weeks ahead for weekend events in Auburn, sooner during peak wedding and festival season. Trailers move fast on weekends, and late requests often land you a smaller unit than planned. Use the request a quote page to lock a date.
Does a 4 stall restroom trailer need a level pad?
Yes. The trailer needs firm, level ground to sit correctly and to keep doors and plumbing working right. Gravel, pavement, or packed dirt all work. Grass that is soft or sloped usually does not, so flag that during your porta potty placement guide walk-through.
Can I add handwashing stations separately?
Yes, even though the trailer includes sinks. Large events often add a standalone portable sink rental near food service or a bar area to keep lines shorter at the trailer itself.
What is the difference between a 4 stall and an 8 stall trailer?
Stall count and guest capacity. The 8 stall restroom trailer suits crowds over 150, while a 4 stall trailer fits mid-size weddings, festival restroom rental needs, and smaller job sites well.
Is a 4 stall trailer available for emergency situations?
Yes, subject to availability. Storm damage, septic failure, or a sudden venue change all qualify. Call the emergency porta potty rental line or check emergency septic service if the trailer is replacing a failed system rather than adding capacity.
