A 4 stall restroom trailer runs 4 private stalls with sinks, lighting and flush plumbing, built for jobs where 40 to 150 people need real restrooms, not portholes. San Tan Valley Porta Pros sizes trailers by headcount and job length before quoting. Weekly trailer rentals fall between 150 and 1,650 dollars depending on the unit and job.
Four separate stalls, running water, interior lighting and a flush system that does not need a hose bib nearby, assuming the tank capacity holds. This is a step up from a standard porta potty rental or even a deluxe flushable porta potty, because guests get doors that lock, sinks that drain, and a floor that is not a plastic pan. For weddings and corporate events around San Tan Valley, that difference matters. Compare it against a 2 stall restroom trailer if your headcount is smaller, or step up to an 8 stall restroom trailer for anything past 150 guests. Add a shower trailer rental for multi-day builds or disaster response, or ask about a luxury restroom trailer for a wedding that wants finished interiors. ADA access is a separate conversation. ADA Standards section 213.2 requires that clustered single-user units include at least one accessible unit, and a trailer with a compliant stall needs a 60 inch turning circle per ADA Standards section 304.3.1. Check the ADA accessible porta potty page or the broader ADA restroom requirements guide before you finalize a headcount-based order.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | 175 | 800 | 2500 |
| Week | 150 | 1397 | 1650 |
| Event | 2499 | 3500 | 3899 |
Day rates swing hard because a single-day drop for a small backyard party costs far less than a full weekend wedding buildout, which runs closer to a weekend premium in prose, not the table above. Delivery adds a separate line, and delivery fees for daily jobs range from 100 to 500 dollars depending on distance from San Tan Valley. If your event runs multiple days back to back, compare the restroom trailer rental cost page against a straight porta potty rental cost breakdown to see where the trailer earns its price and where a standard unit does the job cheaper. For recurring monthly use on a jobsite, the monthly porta potty rental page covers standard units instead, since trailers are usually short-term rentals.
Guest experience and code compliance are the two real reasons. A construction crew under OSHA 1926.51(c)(1) needs 1 toilet for every 20 workers on site, and standard units satisfy that ratio cheaper per head than a trailer does, so most construction site services jobs stick with standard units or the porta john rental line. Events are different. A wedding restroom rental, a festival restroom rental, or a county fair restrooms setup all benefit from finished interiors that do not read as jobsite equipment. Handwashing still needs to meet 29 CFR 1910.141(d)(2), which requires soap and towels or a dryer, not just sanitizer, so pair any trailer with a handwashing station rental if your sink count runs short. San Tan Valley sits far enough from Phoenix proper that delivery routing matters. Florence is 17.3 miles southeast and Apache Junction is 18.5 miles north, both inside normal delivery range for San Tan Valley Porta Pros.
Comfortably 40 to 150 guests over a several-hour event, depending on food and drink service. For all-day festivals or multi-session events in San Tan Valley, size up to an 8 stall restroom trailer rather than double-booking a 4 stall unit.
Most units carry onboard tanks, so a hookup is not required, but a water connection extends service life on multi-day rentals. Ask San Tan Valley Porta Pros to confirm tank capacity against your guest count and event length.
Yes, if the surface is stable and level enough for delivery. ADA Standards section 302.1 requires stable, firm, slip-resistant surfacing wherever an accessible stall is included, so confirm ground conditions before delivery day.
Placement on private property usually does not need a permit, but anything touching a public right of way needs confirming with the city directly. See porta potty permit requirements before you finalize placement.
Standard trailers focus on function: sinks, stalls, lighting. A luxury restroom trailer adds finished cabinetry, upgraded fixtures and climate control, built for weddings and corporate events where appearance matters as much as capacity.
