A 4 stall restroom trailer gives four private stalls, running water and climate control for events or job sites running 75 to 150 people a day. Weekly rental for a trailer of this size runs 150 to 1650 dollars depending on features, and daily rates start around 175 dollars. Saint Paul crews use them when standard units alone are not enough.
Four stalls works for weddings, block parties and mid-size job sites where a bank of standard porta potty rental units feels too basic but an 8 stall restroom trailer is more than the guest count needs. If you are unsure, our how many porta potties do I need guide walks through headcount math. For construction crews, OSHA 1926.51(c)(1) sets toilet ratios by worker count: one facility for 20 workers or fewer, then one seat and one urinal per 40 workers as you scale up. A 4 stall unit often covers a crew right at that first threshold without renting a second trailer. Compare against a 2 stall restroom trailer if your site in Saint Paul or nearby Roseville, 9.0 miles northwest, runs leaner.
Pricing depends on duration and finish level. A basic 4 stall unit for a weekend event lands in a different bracket than a week-long construction rental. See the restroom trailer rental cost page for the full picture across trailer sizes.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| weekend | 900 | 2000 | 3000 |
| week | 150 | 1397 | 1650 |
| event (flat) | 2499 | 3500 | 3899 |
Delivery adds a separate fee, typically 100 to 172 dollars depending on whether it is a day rental or a longer job. Ask about our luxury restroom trailer option if the event calls for upgraded finishes, or check restroom trailer rental for the base lineup.
Not automatically. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent are accessible, with a minimum of one. A 4 stall trailer needs its own accessible stall built to spec, including a 60 inch turning circle under ADA Standards section 304.3.1 and door clearance meeting ADA Standards section 404.2.3 at 32 inches minimum. Not every 4 stall trailer on the market includes this. Ask directly, or upgrade to our ADA accessible porta potty as a standalone add-on for large Saint Paul events where guest accessibility is non-negotiable. Full detail lives on our ADA restroom requirements page.
Placement matters too. Trailers need a level pad and enough clearance for delivery and pump-out access, similar to the 60 feet of straight clearance a roll-off truck needs behind it. Our porta potty placement guide covers ground requirements, and if the trailer sits in a public right of way anywhere in Saint Paul, that placement needs confirming with the city before delivery day.
Saint Paul weddings, fundraisers and multi-day builds all lean on this size. If your event is smaller, look at event restroom rental or wedding restroom rental for scaled-down options. For job sites, pair the trailer with a handwashing station rental to meet 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device, not sanitizer alone. Crews doing exterior coating or pesticide work should also review OSHA 1926.51(f)(1), which requires washing facilities specifically for paint, coating, herbicide or insecticide exposure.
Book two to four weeks out for weddings and festivals, sooner during peak summer months. Construction rentals booked for a fixed job length are easier to schedule last-minute. Call Saint Paul Porta Pros early if your date falls on a busy weekend.
Yes, most trailers carry an internal freshwater tank and holding tank, so no hookup is required for short events. Longer rentals may benefit from a hookup if available on site.
Most 4 stall trailers need standard power for lighting, climate control and water pump function. A generator works if the site has no outlet nearby; ask Saint Paul Porta Pros about pairing one.
A trailer offers flush toilets, sinks and climate control; a standard porta potty rental unit is self-contained with a 60 to 70 gallon tank and no plumbing. Trailers cost more but feel closer to indoor restrooms.
