An 8 stall restroom trailer gives large events or big job sites enough capacity to stop bathroom lines cold, and pricing lands between $2,499 and $3,899 for a full event booking. St. Louis Porta Pros sets these units for festivals, multi-day builds and weddings across the metro. Weekly and daily terms exist too, depending on your event.
Trailer pricing depends on duration and how far the unit travels to reach you. A day rate runs $175 to $2,500 depending on trailer class, a week runs $150 to $1,650, and a full event package (the common choice for an 8 stall unit) runs $2,499 to $3,899. Delivery adds a separate fee, and that fee scales with distance: expect more if you are out past Chesterfield, 19.2 miles west, than if you are inside St. Louis proper. Compare against smaller options on the restroom trailer rental cost page, or check the 2 stall and 4 stall trailers if 8 stations is more than your headcount needs. For straight portable toilets instead of a trailer, see portable toilet rental and the porta potty rental cost breakdown.
| duration | low | typical | high |

| week | 150 | 1397 | 1650 |

Eight stalls suits crowds well beyond backyard-party size, think festivals, fairs, or a multi-day job site with a big crew. OSHA 1926.51(c) sets construction ratios at one toilet for 20 workers or fewer, stepping up as headcount grows, so an 8 stall unit can cover a sizable crew on its own without extra standalone units. For events, our how many porta potties do I need guide walks through headcount math in more detail. If your crowd runs smaller, look at the standard porta potty rental or deluxe flushable porta potty instead of stepping straight to an 8 stall trailer. Weddings and golf outings often land in the middle: see wedding restroom rental and golf tournament restrooms for sizing examples closer to that range. County fairs and festivals in St. Louis tend to need the full 8 stall count once attendance climbs past a few hundred; our festival restroom rental and county fair restrooms pages cover that scale directly.
At least one stall in a clustered restroom setup must be accessible under ADA Standards 213.2, and that unit needs a 60 inch turning circle per ADA Standards 304.3.1 along with a 32 inch clear door opening per ADA Standards 404.2.3. Our ADA accessible porta potty page and ADA restroom requirements guide cover the fuller standard, including the 36 inch route width required under ADA Standards 403.5.1. On the delivery side, an 8 stall trailer is a full-size unit, and our roll-off crews know that a straight clearance path matters, the same 60 foot clearance rule that applies to roll-off dumpster rental deliveries applies loosely to trailer placement too: flat, stable ground and a clear approach make setup faster. Water and power hookups matter as well; OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, which our trailers carry onboard. If you are near University City, 7.9 miles northwest, or Webster Groves, 8.6 miles southwest, delivery is a short run from our St. Louis base. See the restroom trailer rental pillar page for the full lineup, including the luxury restroom trailer and shower trailer rental options.
Yes. These units carry an onboard freshwater supply, so they work on job sites and rural venues around St. Louis without a hydrant nearby. Confirm generator needs at booking, since lighting and pumps draw power. Ask about placement on grass versus gravel too.
Book as early as you can once a date is set, especially for weekend events. Trailer inventory is limited compared to standard portable toilets, and festival season fills fast. A request a quote call early locks the unit and the delivery slot together.
Permit rules depend on placement and property type, and city confirmation is needed before curb or right-of-way setups. Check our porta potty permit requirements page, then confirm directly with the city for your specific address before delivery day.
Delivery, setup, and pickup are standard, plus restocking during multi-day events. Interior finish varies by trailer class, from basic to the luxury restroom trailer line. Ask what is bundled versus billed separately, since delivery fees are quoted apart from the trailer rate itself.
Yes, multi-day festivals and fairs typically get a scheduled service visit, similar in spirit to the weekly baseline interval described in ANSI/PSAI Z4.3 for standard units. Longer or higher-traffic events may need more frequent stops. Discuss service frequency when you book so restocking matches your crowd size.
