A 4 stall restroom trailer runs 175 to 2500 dollars a day depending on rental length and finish level, with weekly rates landing between 150 and 1650 dollars. It fits weddings, multi-day festivals and construction site services across South Suffolk that need more capacity than a bank of standard porta potty rental units can give, and it pairs well with a handwashing station rental for larger crews.
Think of it as four private rooms on wheels, each with its own door and flushing fixture, instead of four separate boxes lined up in a lot. South Suffolk Porta Pros pulls these units on a trailer chassis that needs roughly 60 feet of straight clearance behind the truck to set up, so tell us upfront if your site is tight, and check the porta potty placement guide if you are unsure about clearance. This size sits between the 2 stall restroom trailer and the 8 stall restroom trailer, and it works for crowds in the 100 to 300 person range over a weekend. Compare it against a luxury restroom trailer if the event calls for climate control and finished interiors. For construction crews, pair it with a deluxe flushable porta potty on the far end of the site to cut walk time. If you are still deciding on unit count, run the numbers through how many porta potties do i need before you commit to a trailer size, and browse the restroom trailer rental lineup for other configurations, including a shower trailer rental for multi-day camps.

Pricing depends on how long you need it and how far the delivery crew has to travel. A day rate covers a single event day, a week rate suits a multi-day build in Carrsville or a job running 16.1 miles west of South Suffolk, a month rate fits a longer construction stretch, and you can check the monthly porta potty rental page for how that compares against standard units.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | 175 | 800 | 2500 |
| Week | 150 | 1397 | 1650 |
| Event (flat) | 2499 | 3500 | 3899 |
Delivery adds a separate fee, and weekend jobs often run at a premium over a straight day rate, so ask for both numbers when you request a quote. For a deeper breakdown of what drives price up or down, see restroom trailer rental cost and the general porta potty rental cost page, or compare against the porta potty rental per day rates for smaller jobs.
Placement in the public right of way needs confirming with the city before delivery day. We have not verified a specific South Suffolk ordinance for trailer placement, so do not assume your driveway or curb cut is automatically clear. Check with the city and lean on our crew for site layout once you know the answer, and see the dumpster permit requirements page if you are also ordering a roll-off for the same site. This matters more on tight residential lots than open fields, and the same question comes up on the porta potty permit requirements page. If the trailer serves a construction crew, OSHA 1926.51(c) sets toilet counts by headcount, and a 4 stall unit generally covers a crew in the 60 to 90 worker range comfortably. Review the fuller breakdown at osha portable toilet requirements before you order, and pair the trailer with a temporary fence rental if the site needs to stay secured overnight.
Accessibility matters too. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent be accessible, with a minimum of one. A 4 stall trailer usually needs a separate ADA accessible porta potty or ADA-equipped trailer bay alongside it, not folded into the four stalls. See ada restroom requirements for the door and clearance specs.
Comfortably, 100 to 300 guests over a single event day, less if it is a full weekend with heavy use. For construction crews working 8 to 10 hour shifts, figure 60 to 90 workers before you need a second unit. Match it against expected traffic, not just headcount.
Most units carry onboard fresh and waste tanks, but a hookup extends run time on multi-day events. OSHA 1926.51(a)(1) requires potable water at the jobsite regardless of hookup, so we confirm your source during the quote.
Yes, if the ground is level and can support the trailer's weight without sinking. We check the surface during the site walk and bring leveling blocks when needed. Steep grades or soft mud usually rule out a spot.
Book 4 to 6 weeks out for peak wedding season, sooner if your date lands on a busy festival weekend, and check festival restroom rental if you are planning a larger public event instead. Trailers move fast in warmer months. See wedding restroom rental for planning specifics.
Stall count sets your ceiling on simultaneous users, not just total headcount. An 8 stall trailer roughly doubles throughput for the same event window. Compare footprints and pricing on the 8 stall restroom trailer page before deciding.
