What Is a 4 Stall Restroom Trailer Good For?
Think weddings, company picnics, block parties, and multi-day construction jobs where a standard porta potty rental feels too bare-bones for guests. A 4 stall unit usually splits into two sides, so men and women do not share a line, and each side has its own sink. Cincinnati Porta Pros sets these up for event restroom rental bookings all over the city, from backyard wedding restroom rental setups to festival restroom rental grounds downtown. If your headcount runs past 300, step up to an 8 stall restroom trailer; if it is under 75, a 2 stall restroom trailer or a handful of portable restroom rental units might do the job cheaper. Pair the trailer with a handwashing station rental near a food tent if you want extra wash capacity outside the trailer sinks, since OSHA 29 CFR 1910.141(d)(2) requires soap and towels or a hand dryer at any washing station, not just sanitizer.
How Much Does a 4 Stall Restroom Trailer Cost in Cincinnati?
Trailer pricing swings hard depending on trim, event length, and delivery distance. Here is what actually shows up in rental quotes:
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | 175 | 800 | 2,500 |
| Weekend | 900 | 2,000 | 3,000 |
| Week | 150 | 1,397 | 1,650 |
| Event (multi-day) | 2,499 | 3,500 | 3,899 |
A single day rate covers a quick delivery-and-pickup job; most weddings and festivals book the weekend or event rate instead. If your budget is the deciding factor, compare against the full restroom trailer rental cost breakdown or check standard unit pricing on the porta potty rental cost page before you commit to a trailer. Delivery fees run separately and depend on how far the site sits from Cincinnati; Cincinnati Porta Pros has delivered as far as Fairfield, about 16.8 miles north, and Mason, 22.3 miles northeast, so distance matters when you request a quote.
Is a 4 Stall Restroom Trailer ADA Accessible?
Not automatically. Most 4 stall trailers are built for standard use, and you need to request an accessible unit specifically. ADA Standards section 213.2 requires that where portable toilet units are clustered, at least 5 percent of them be accessible, with a minimum of one. For a trailer that means confirming a ramp with a slope no steeper than 1:12 per ADA Standards section 405.2, a door opening of at least 32 inches under section 404.2.3, and a 60 inch turning circle inside per section 304.3.1. If your event needs guaranteed accessible capacity, ask about an ada accessible porta potty as a standalone unit alongside the trailer, or check the full ada restroom requirements guide before the guest list is final. Cincinnati venues with tight lot access sometimes need this planned out in advance.
Construction crews running a 4 stall trailer alongside standard units should still hit OSHA 1926.51(c) toilet ratios for the whole crew count, not just what the trailer covers. Our osha portable toilet requirements page walks through the ratio table by crew size.
Where can I place a 4 stall restroom trailer on my property?
You need a level pad with enough clearance for delivery, similar to the 60 feet of straight clearance a roll-off truck needs behind it. Grass, gravel, or asphalt all work if it is firm and stable under ADA Standards section 302.1. See the porta potty placement guide for site prep details.
Does a 4 stall trailer need a permit in Cincinnati?
Placement in the public right of way needs confirming with the city; we have not verified a blanket permit rule for private-lot placement. Check the porta potty permit requirements page and confirm with the city before delivery day.
How many people can a 4 stall trailer realistically serve?
Comfortably 100 to 300 guests over a few hours, more with rotation. Use our how many porta potties do i need guide to size it against your actual headcount and event length.
Can I upgrade to a nicer restroom trailer for a wedding?
Yes. Ask about a luxury restroom trailer if you want finished interiors, climate control, and better fixtures than a standard 4 stall unit offers.
What is the difference between a 4 stall and an 8 stall trailer?
Stall count and line speed. An 8 stall restroom trailer roughly doubles capacity for guest counts over 300, while a 4 stall keeps costs down for smaller Cincinnati gatherings.
