A 4 stall restroom trailer serves crews and guest counts that outgrow single units without jumping to a full 8-stall rig. Rental runs from a day to a week, with weekly trailer pricing landing between 150 and 1,650 dollars depending on build. Vista Porta Pros sets it level, connects power, and walks you through hookup before the crew leaves.
Four-stall trailers split roughly in half: two stalls per side, sometimes one side flagged for each gender with its own entrance. Compare that footprint against a 2 stall restroom trailer if your headcount is smaller, or size up to an 8 stall restroom trailer for larger builds or weekend festivals. Every model in the restroom trailer rental lineup ties into a fresh water supply and needs reasonably level ground. ADA Standards section 405.2 caps ramp slope at 1:12, so if a stall is wheelchair accessible, Vista Porta Pros checks the approach grade before setup, not after. Door openings meet ADA Standards section 404.2.3 at a 32 inch minimum clear width, and inside, ADA Standards section 304.3.1 calls for a 60 inch turning circle. If your event or job needs a fully dedicated accessible unit instead, look at the ADA accessible porta potty page. For most Vista job sites, a 4 stall unit covers mid-size crews without daily line-ups at the door.
Pricing follows duration, not headcount alone. A single day rental sits at the low end of the trailer band; a full week or multi-day event climbs from there. Full detail lives on the restroom trailer rental cost page, and side-by-side comparisons against porta potties are on the porta potty rental cost guide.
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2500 |
| week | 150 | 1397 | 1650 |
| weekend | 900 | 2000 | 3000 |
| event (multi-day) | 2499 | 3500 | 3899 |
Delivery adds a separate line, typically 50 to 150 dollars for a weekly rental based on distance from Vista Porta Pros' yard. Crews near Lake San Marcos, about 6.5 miles south of Vista, or Hidden Meadows, 11.1 miles east, usually land near the lower end of that delivery range. Jobs out toward Fallbrook, 16.2 miles north, or Poway, 22.8 miles southeast, run closer to the top. If a standard porta potty covers the job instead, check the standard porta potty rental or portable toilet rental pages before committing to a trailer.
Weddings, county fair vendor rows, and multi-day construction jobs are the usual fit. For weddings specifically, see wedding restroom rental; for fairground layouts, county fair restrooms covers spacing. On a construction site, OSHA 1926.51(c)(1) sets toilet ratios by headcount, one per 20 workers up to 20, then one toilet and one urinal per 40 up to 200. A 4 stall trailer can satisfy that math for a crew in the 60 to 80 range depending on shift overlap. Sites also handling paint, coatings or solvents trigger washing facilities under OSHA 1926.51(f)(1), which the trailer's built-in sinks cover on top of general use. If you are unsure how many stalls your headcount actually needs, how many porta potties do I need walks through the math, and OSHA portable toilet requirements covers the regulation in full. Vista Porta Pros also handles the temporary fence rental and light tower rental that often accompany a multi-day rental.
Comfortably 100 to 150 guests over a single event day, or a construction crew up to roughly 80 depending on shift patterns. ANSI/PSAI Z4.3 sets a baseline service interval of once weekly for units serving 10 users over 40 hours; Vista Porta Pros adjusts servicing for higher-traffic trailer rentals.
Most 4 stall trailers run lighting, fans and pumps off standard power, and Vista Porta Pros can supply a temporary power pole if the site has no outlet nearby. Confirm amperage needs when booking.
Plan for roughly 60 feet of straight clearance behind the delivery truck, similar to roll-off drop requirements. Tight driveways or alleys in older Vista neighborhoods sometimes need a site visit first.
Yes. Many renters pair the trailer with standalone units from handwashing station rental for overflow near food service or paint areas, satisfying 29 CFR 1910.141(d)(2) requirements for soap and drying devices.
Trailers do not have an hourly rate, but short events can still book a single day. For shorter jobs or tighter budgets, compare against the porta potty rental per day page before deciding.
