How Many People Can a 4 Stall Restroom Trailer Handle?
A 4 stall unit is built for events and crews in the 100 to 300 person range, though exact counts depend on hours and whether alcohol is served. For construction sites, OSHA 1926.51(c) sets the baseline: one toilet facility per 20 workers, moving to more fixtures as headcount climbs past 20 and again past 200. A 4 stall trailer often covers a crew of 40 to 60 comfortably, which makes it a common upgrade from a row of units on a construction site services job. For weddings and private parties, check the wedding restroom rental guide for guest-count math, and compare against the 2 stall restroom trailer or 8 stall restroom trailer if your numbers sit outside that middle range. Kissimmee event planners booking anything with a bar or catering line should size up rather than down.
What Does a 4 Stall Restroom Trailer Cost in Kissimmee?
Pricing splits by duration, and a longer rental never costs less per day than a short one. Delivery is billed separately and depends on distance and site access.
| Duration | Typical Range |
|---|---|
| Day | $175 - $2,500 |
| Week | $150 - $1,650 |
| Weekend | $900 - $3,000 |
| Event (multi-day) | $2,499 - $3,899 |
Delivery fees on top of the trailer rate typically run $100 to $500 for a day rate or $50 to $150 for a week, depending on how far the crew has to haul the unit. For a full cost breakdown across unit types, see restroom trailer rental cost or the general porta potty rental cost page. If your job is longer than a month, ask about the monthly porta potty rental structure instead, since a standalone trailer quote won't always beat combining units.
Where Can a 4 Stall Restroom Trailer Be Placed on Site?
Placement comes down to clearance and grade. A roll-off delivery needs about 60 feet of straight clearance behind the truck, and a restroom trailer needs similar room to back in and level. The ground has to be stable and reasonably flat; ADA Standards section 302.1 calls for surfaces that are stable, firm and slip resistant, and that's a good baseline even where full accessibility isn't required. If ADA access is needed, pair the trailer with an ADA accessible porta potty unit, since ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible. Check the porta potty placement guide before delivery day, and confirm any right-of-way question with the city directly, since placement rules in public areas need to be verified case by case. Homeowners in Kissimmee doing a renovation with limited driveway space should look at the home renovation porta potty page for smaller footprint options instead.
Sites near Hunters Creek, about 5.2 miles north of Kissimmee, or Campbell, roughly 4.9 miles southwest, fall inside typical delivery range without extra mileage charges in most cases. Buenaventura Lakes sits about 7.3 miles northeast and is still a routine run for our trucks.
Does a 4 stall restroom trailer need a generator or power hookup?
Most units run on a standard outlet or built-in battery for lighting and pumps, but larger deluxe trailers with climate control may need a dedicated circuit. Ask about power needs when you book. Pair with a temporary power pole if the site has no existing service.
Can a 4 stall restroom trailer be rented for a single weekend?
Yes. Weekend rates for a 4 stall trailer generally run $900 to $3,000, which covers Friday delivery through Monday pickup on most jobs. Book early for peak wedding season since weekend inventory moves fast.
How often is the tank serviced during multi-day rentals?
For week-long or event-length rentals, service follows a schedule similar to ANSI/PSAI Z4.3's baseline of one visit per week for moderate use; higher headcounts need more frequent pumping. Ask your Kissimmee Porta Pros rep to build a service plan around your guest count.
Is a 4 stall trailer better than renting multiple standard units?
For events over 100 guests, yes, since a trailer keeps lines shorter and includes sinks. For smaller jobs, standard units from portable toilet rental may cost less overall. Compare against the how many porta potties do i need guide.
What's the difference between standard and deluxe finish?
Deluxe trailers add features like flushing fixtures and interior finishes similar to the deluxe flushable porta potty line, at a higher day rate. Standard 4 stall trailers cover most job sites and mid-size Kissimmee events without the upgrade cost.
