A 4 stall restroom trailer covers events and job sites of roughly 150 to 300 people without a line forming at every stall. San Clemente Porta Pros runs these units on weddings, weekend festivals and multi-week construction jobs, with delivery scheduled around your site access and power needs.
A 4 stall unit works well for gatherings up to 300 guests over a single event day, or a mid-size crew on a construction site running multiple shifts. For anything bigger, step up to the 8 stall restroom trailer; for something smaller, the 2 stall restroom trailer is usually enough. On job sites, OSHA 1926.51(c) sets toilet counts by headcount, and pairing a trailer with standalone units keeps you compliant when the crew grows. San Clemente contractors building near the pier or along Avenida Del Mar often mix a trailer with a few standard porta potty rental units for overflow. If you are not sure which size fits, the how many porta potties do I need guide walks through the math, and our construction site services page covers combining trailers with dumpsters and fencing on the same site visit.
Pricing depends on rental length and whether it is a single weekend event or an extended job. Below is where a 4 stall unit typically lands against the broader trailer range.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $175 | $800 | $2,500 |
| Week | $150 | $1,397 | $1,650 |
| Weekend | $900 | $2,000 | $3,000 |
| Multi-day event | $2,499 | $3,500 | $3,899 |
A delivery fee applies separately and generally runs $100 to $500 depending on distance and site access; see restroom trailer rental cost for a fuller breakdown. If your event is closer to San Juan Capistrano, 7.6 miles northwest of San Clemente, or Dana Point, 6.5 miles west, drive time factors into that delivery quote. For weddings and private parties, many clients look instead at the luxury restroom trailer with upgraded finishes, still built on the same stall-count logic.
Trailers need a level pad, roughly the trailer's footprint plus room to open the entry ramp, and clear access for the delivery truck. ADA Standards section 405.2 caps ramp slope at 1:12, which our crews check when the pad has any grade. If your event needs an accessible unit alongside the trailer, ADA Standards section 213.2 requires at least one accessible unit in a cluster of single-user toilets, and our ada accessible porta potty page covers that separately from trailer stalls. Placement in the public right of way in San Clemente needs confirming with the city before delivery day; check our porta potty permit requirements and porta potty placement guide before you lock in a spot. Most residential driveways and paved lots work fine. Grass and soft soil sometimes need plywood tracking, which our dispatch team can flag during the site walk-through. For larger footprints alongside dumpsters or fencing, see temporary fence rental and roll-off dumpster rental for what else typically shares the pad.
Most units run interior lights, climate control and pump systems off a standard outlet, but larger trailers with more fixtures may need a dedicated circuit. Ask about power needs when you book. Sites without nearby power sometimes pair the trailer with a temporary power pole or a light tower rental for evening events.
ANSI/PSAI Z4.3 sets a baseline of one service visit per week for typical use, but multi-day events with heavy traffic usually need daily servicing. We schedule around your event calendar, not a fixed interval.
Yes, for guest counts up to roughly 300 over the event window. Check wedding restroom rental for setup timing and add-ons like sinks and mirrors that most wedding clients request alongside the trailer.
A trailer offers flush fixtures, sinks and climate control inside an enclosed unit; standard units are single-stall and self-contained. See portable restroom rental for how the two compare on cost and footprint.
Permit rules depend on where the trailer sits, especially near a public street. Confirm placement with the city before delivery; our porta potty permit requirements page has the questions to ask.
