A 4 stall restroom trailer serves an event of roughly 150 to 300 guests over a weekend before anyone waits in line. Rental for this size runs about 150 to 1650 dollars for a week, with weekend bookings priced in the 900 to 3000 dollar range. Oak Park Porta Pros stocks these for weddings, block parties and job sites that outgrow a standard porta potty rental.
Four stalls works for mid-size gatherings, roughly 150 guests for a wedding reception or 200 for a daytime festival, but the right count depends on hours and whether alcohol is served. If you are unsure, run the numbers on our how many porta potties do I need guide before booking. For crews rather than guests, OSHA 1926.51(c) sets facility ratios by headcount on construction sites, which is a different math than event planning. Weddings in Oak Park often pair a trailer with a smaller unit for overflow near the bar; see wedding restroom rental for that setup. Compare a 4 stall against smaller and larger options on our 2 stall restroom trailer and 8 stall restroom trailer pages before you commit. Job sites in Oak Park lean toward our construction site services package instead, since a trailer this size is usually overkill for a five-person crew.
Expect climate control, interior lighting, and separate stalls with real doors, not the single-unit layout of a porta john rental. ADA Standards section 404.2.3 sets a 32 inch minimum clear door opening, and section 403.5.1 calls for a 36 inch clear route, both worth checking if guests will use wheelchairs or a stroller. If you need a unit built to that standard specifically, look at our ADA accessible porta potty page rather than assuming the trailer covers it. For a step up in finish, our luxury restroom trailer line adds finishes a standard 4 stall does not include. Trailers need level, solid ground to sit right; a gravel drive or parking lot in Oak Park works, and delivery needs enough straight clearance to back in, similar to what we ask for a roll-off dumpster rental drop. If your event needs cold water for hands, not just a toilet, add a unit from handwashing station rental nearby.

Multi-day festivals and marathons often land in the event-rate tier rather than a daily one; see festival restroom rental or marathon and race restrooms for those bookings. A delivery fee applies on top of the unit price, generally 100 to 500 dollars depending on distance and timing, which is the same delivery structure used for a portable restroom rental order. Oak Park sits 3.4 miles east of Maywood and 4.6 miles east of Melrose Park, and delivery pricing accounts for that kind of drive time. For the full cost breakdown across unit types, our restroom trailer rental cost page covers it in more depth than this one does.
Placement on private property is usually fine without extra paperwork, but putting a trailer in the public right of way needs confirming with the City of Oak Park directly. We have not verified a specific permit rule for trailer placement, so check with the city before setting a date. See porta potty permit requirements for the general process.
Plan for a level pad plus room for the delivery truck to back in and level the trailer once parked. A roll-off delivery needs about 60 feet of straight clearance behind the truck, and trailers need similar room. Confirm your site layout using our porta potty placement guide.
Most 4 stall trailers need a standard water hookup and household power; ask about your site's access when booking. OSHA 1926.51(a)(1) requires potable water at all places of employment, which matters if this trailer serves a job site rather than a private event.
Service intervals depend on guest count and hours of use. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users over a 40 hour stretch, so a busy weekend event usually needs mid-event servicing scheduled in advance.
A trailer has enclosed stalls, lighting and often climate control; a standard unit is a single 44 by 48 inch footprint with a 60 to 70 gallon tank. Compare both directly on our portable toilet rental overview page.
