How Many Stalls Do I Actually Need?
Guest count and event length drive the math more than anything else. A wedding of 150 people over four hours sits comfortably with an 8 stall unit split for men and women, while a two-day festival with beer service pushes crowds harder and faster. Construction crews use a different standard: OSHA 1926.51(c)(1) sets toilet ratios by headcount, one facility for 20 workers or fewer, scaling up from there. That rule applies to job sites, not weddings, but it's a useful gut check for any project running dozens of workers through construction site services in Salt Lake City. If you're not sure which category your event falls into, our restroom trailer rental guide and the how many porta potties do I need page both walk through the count. For anything under 100 guests, a 2 stall restroom trailer usually does the job for less.
What Comes Inside an 8 Stall Trailer?
Expect climate control, running water, and interior lighting, split evenly between men's and women's sides. Each stall flushes, unlike a standard porta potty, and sinks run on a fresh water tank rather than a hand sanitizer pump, which matters under 29 CFR 1910.141(d)(2) since sanitizer alone doesn't satisfy a handwashing requirement. Compare that to our deluxe flushable porta potty option, which flushes but skips the climate control and mirrors. Weddings at outdoor Salt Lake City venues often pair the trailer with a handwashing station rental near the catering tent, since guests wash hands there more than inside the stalls. If the site needs an accessible unit too, ADA Standards section 213.2 requires at least one accessible unit in any cluster, and our ADA accessible porta potty page covers the specifics, including the 36 inch clear route required under ADA Standards 403.5.1.
Do I Need a Permit for a Restroom Trailer in Salt Lake City?
Placement in the public right of way needs confirming with the city before delivery, since we haven't verified a specific ordinance for trailer siting on private versus public property. What we do know: the delivery truck needs roughly 60 feet of straight clearance behind it to set the trailer level, same as our roll-off dumpster rental trucks need for a bin drop. If your venue sits on gravel, grass, or a slope, mention that when you call, because leveling changes setup time. Events near South Salt Lake, about 7.9 miles south, or Bountiful, 9.9 miles northeast, still fall under our standard delivery radius, so distance rarely changes the quote. Check our porta potty permit requirements page for what we do have confirmed, and browse service areas if your event sits outside Salt Lake City proper, including Murray and Taylorsville.

Multi-day construction jobs usually land in the week column, while weddings and festivals book the weekend or event rate. For year-round comparisons across every unit type, see our restroom trailer rental cost breakdown or the general porta potty rental cost page.
How far in advance should I book an 8 stall trailer?
Book 4 to 8 weeks out for weddings and festivals, since trailers move fast during Salt Lake City's summer event season. Construction rentals can often book with a week's notice. If your date's close, call anyway. Check our request a quote page.
Can the trailer run without a generator hookup?
It needs power, either shore power or a generator, to run lighting and climate control. If your site lacks power, ask about a temporary power pole or generator add-on when you book.
Is an 8 stall trailer better than renting several standard units?
For weddings and upscale events, yes, since guests get flushing toilets and real sinks. For rough construction sites, standard units cost less and hold up better to mud and heavy traffic. Compare both on our portable restroom rental page.
Does the trailer need its own water tank?
Yes, it carries fresh water for sinks and flushing separate from any hose hookup. We fill it before delivery and can top it off during multi-day rentals, similar to service on a holding tank rental.
What if my event runs longer than planned?
Call us before the pickup date. Extending is usually easier than re-booking, and we'd rather adjust the invoice than rush a swap. See contact for direct lines during event weekends.
