How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably cover mid-size gatherings, and the right count depends on headcount and hours, not just guest list size. If you are planning a wedding reception or a company picnic in Kansas City, this size usually splits the difference between a 2 stall restroom trailer for something small and an 8 stall restroom trailer for a festival crowd. For construction crews, OSHA 1926.51(c)(1) sets the baseline: one toilet facility for 20 workers or fewer, then additional fixtures as the crew grows past that. If you are unsure which way to round, how many porta potties do I need walks through the math, and our construction site services page covers job site setups directly. Event hosts should also check event restroom rental for guidance specific to parties and receptions rather than crews.
What Does a 4 Stall Restroom Trailer Cost in Kansas City?
Pricing depends on rental length, trailer finish and delivery distance. Below is what a standard-class trailer in this size range runs, per the pricing bands we track:
| Duration | Typical Range |
|---|---|
| Day | 175 to 2,500 |
| Weekend | 900 to 3,000 |
| Week | 150 to 1,650 |
| Event (multi-day) | 2,499 to 3,899 |
Delivery adds a separate charge, generally 100 to 500 dollars for a day rental or 50 to 150 dollars over a full week, and a roll-off style delivery truck needs about 60 feet of straight clearance behind it to set the trailer safely. For a deeper cost breakdown across unit types, see restroom trailer rental cost or the general porta potty rental cost page. If your event runs a single day, porta potty rental per day shows how daily and weekly math compares. Want something nicer than standard finish? Look at luxury restroom trailer options, and for showers on top of restrooms, shower trailer rental covers that combination.
Where Can We Place a 4 Stall Restroom Trailer on Our Property?
Placement needs level ground, road access for delivery, and enough clearance for the door swing and the truck itself. ADA Standards section 405.2 limits any access ramp to a 1:12 running slope, and ADA Standards section 403.5.1 requires a 36 inch clear route to the trailer if you need an accessible path. Our porta potty placement guide covers ground and access requirements in more detail. If the site sits inside Kansas City proper, placement in the public right of way needs confirming with the city; check porta potty permit requirements before you commit to a spot near a curb or sidewalk. We deliver throughout the metro, including North Kansas City 2.6 miles northwest and Gladstone 8.2 miles north, and our service areas page lists every town we reach. For sites further out, Liberty sits 15.0 miles northeast and Raytown 13.6 miles southeast, both within normal delivery range.
What is the difference between a 4 stall and an 8 stall trailer?
An 8 stall trailer roughly doubles capacity and works better for festivals or races with a few hundred guests. A 4 stall suits weddings, backyard events and mid-size crews. See 8 stall restroom trailer for specs on the larger unit before deciding.
Do restroom trailers need a water and power hookup?
Most trailers run on an internal fresh water tank and a small generator or standard outlet, so a dedicated hookup usually is not required. Confirm your site has flat, stable ground; ADA Standards section 302.1 requires stable, firm, slip resistant surfaces where accessible units are placed.
Can we get an ADA accessible stall in a 4 stall unit?
Ask when you book. ADA Standards section 213.2 requires at least 5 percent of clustered single-user units to be accessible, never fewer than one, and our ADA accessible porta potty page covers standalone accessible units if the trailer itself lacks one.
How far in advance should we book for a wedding?
Book as early as you can once your date and guest count are set, since trailers move fast during wedding season. Our wedding restroom rental page has seasonal guidance, and request a quote gets you a firm date and price.
Is delivery included in the rental price?
No, delivery is billed separately from the trailer rental itself. Bands run from about 100 to 500 dollars for shorter rentals and drop for full-week terms; see restroom trailer rental cost for the full breakdown before you request a quote.
