What Is a 4 Stall Restroom Trailer?
Think of it as a small building on wheels. Four separate stalls, each with a door, a sink close by, and climate control in most units, so guests are not stepping into a plastic box in July or January. It sits between the smaller 2 stall restroom trailer and the larger 8 stall restroom trailer in the lineup, and it is the workhorse size for wedding restroom rental and mid-size festival restroom rental jobs around Indianapolis. Some renters step up to a luxury restroom trailer finish for corporate events or upscale weddings, same footprint, nicer fixtures. If you need washing stations too, a shower trailer rental pairs well on multi-day sites. For straight cost comparisons across trailer sizes, see restroom trailer rental cost before you commit to a size.
Delivery in Indianapolis needs a level pad and enough clearance to back the trailer in. If your site is tight, ask about placement before delivery day rather than after; our porta potty placement guide covers the same clearance logic that applies to trailers. Compare it against a full restroom trailer rental lineup if four stalls feels like more or less than your headcount needs.
How Many People Can a 4 Stall Restroom Trailer Handle?
Four stalls comfortably serve an event of 150 to 300 guests over a single day, more if you stagger arrival times. For multi-day construction use, OSHA 1926.51(c) sets the baseline: one toilet facility per 20 workers on site, so a crew of 60 to 80 fits well inside four stalls. ANSI/PSAI Z4.3 sets the standard service interval at once per week for up to 10 users across a 40 hour week, which is the number our route techs plan servicing around for longer rentals. If your headcount runs past 300, look at the 8 stall restroom trailer instead, or ask about pairing a trailer with standalone standard porta potty rental units for overflow.

Accessibility matters too. ADA Standards section 213.2 requires that where single-user units are clustered, at least 5 percent be accessible, never fewer than one. If your trailer setup does not include a built-in accessible stall, pair it with an ADA accessible porta potty nearby to stay compliant. Full requirements live at ADA restroom requirements.

Pricing swings on finish level, run time and how far the trailer travels. A site in Speedway, 6.7 miles west of Indianapolis, or Beech Grove, 6.7 miles southeast, sits well within normal delivery range and should not add much to the quote. Longer hauls out toward Noblesville, 21.0 miles northeast, or Westfield, 20.6 miles north, can carry a higher delivery line.

How long can I rent a 4 stall restroom trailer?
Anywhere from a single day to several months. Weekend events, weeklong builds and month-long projects all book the same trailer, just at different rates. Ask about monthly porta potty rental pricing logic if your job runs long term; the same per-day discount curve applies to trailers.
Does the trailer need a power hookup?
Most units run on standard household power, though larger trailers with full climate control may need more. If your site has no power source, ask about a generator add-on or check temporary power pole options for the job site.
Can I put a restroom trailer on grass or gravel?
Yes, as long as the pad is level and the delivery truck has clearance to back in. Uneven ground causes drainage and door-swing problems. Our crew checks the site plan before delivery day.
Do I need a permit for a restroom trailer in Indianapolis?
Placement in the public right of way needs confirming with the city; requirements vary by site and event type. Check porta potty permit requirements before your event date to avoid a last-minute scramble.
What is the difference between a 4 stall and 8 stall trailer?
Stall count and footprint. The 8 stall restroom trailer doubles capacity for larger festivals or big work crews, while four stalls handles most weddings and mid-size jobs around Indianapolis without the extra footprint or cost.
