How Many Stalls Do You Actually Need?
Four stalls sit in the middle of our lineup, between the 2 stall restroom trailer for smaller gatherings and the 8 stall restroom trailer for larger festivals. If you are not sure where your guest count lands, our how many porta potties do I need guide walks through the math, and OSHA 1926.51(c) sets the baseline ratio for job sites at 1 toilet per 20 workers. Events run differently than crews. A wedding of 150 in Provo typically calls for 4 stalls plus one accessible unit under ADA Standards section 213.2, which requires at least one accessible unit whenever units are clustered. If your guest list skews toward an evening reception with alcohol, bump up. Compare against our standard porta potty rental line if flush units are not required, or step up to the luxury restroom trailer for a wedding or corporate event where interior finish matters more than raw capacity.
What Does a 4 Stall Restroom Trailer Cost in Provo?
| duration | low | typical | high |
|---|---|---|---|
| day | 175 | 800 | 2,500 |
| week | 150 | 1,397 | 1,650 |
| event (flat) | 2,499 | 3,500 | 3,899 |
Day rates swing hard because a single weekday rental and a full production build are two different jobs. Weekly bookings flatten that out, which is why contractors doing multi-week builds around Provo often lock in the week rate instead of renewing daily. See the full breakdown on our restroom trailer rental cost page, and if your event only needs one day, our porta potty rental per day page covers the simpler standard-unit option. Delivery adds a separate fee, and our porta potty rental cost page breaks that line out so it is not buried in the headline number.
Do You Need Water and Power Hookups?
Most 4 stall trailers want a water source and a standard outlet nearby; without either, we run self-contained tanks, but flush performance and lighting both improve with a hookup. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, and that applies whether you are running a Provo job site or an outdoor Provo event. If your site has no power, ask about a light tower rental or a temporary power pole to run interior lighting and any pump-assist fixtures. Handwashing is a separate need from the trailer's interior sinks if your crew works with paints, coatings, herbicides or insecticides. In that case OSHA 1926.51(f)(1) requires washing facilities, and a standalone handwashing station rental covers that gap cheaply. For sites near Orem, about 5.6 miles northwest of Provo, or Springville, 6.7 miles south, delivery logistics are the same: our trucks need roughly 60 feet of straight clearance to position the trailer.
Where Can This Trailer Be Placed on Site?
Placement needs a firm, level pad, and ADA Standards section 405.2 caps ramp slope at 1:12 if you are bridging a curb or grade change into the trailer. Our porta potty placement guide covers ground conditions in more depth. Right-of-way placement in Provo needs confirming with the city directly; we have not verified a blanket rule for trailer placement on public streets, so check with the municipal permitting office before you commit to a curbside spot. For private lots and backyards this is rarely an issue.
How many people can a 4 stall restroom trailer handle in one day?
Figure 100 to 300 guests over a single event day, depending on how concentrated your traffic is. A wedding reception spreads use over several hours; a concert crowd hits all four stalls in the first thirty minutes. Talk headcount through with us before booking.
Does the 4 stall trailer need to be plumbed into a sewer line?
No. Most units run on internal holding tanks and get pumped out after the event, same as our septic pumping service handles residential tanks. A direct sewer hookup is possible on some sites but not required.
Can I rent a 4 stall trailer for a multi-day construction job?
Yes. Weekly and monthly terms both exist for this reason, and combining it with a construction site services package covers fencing and dumpsters at the same time. Check our construction dumpster rental page too.
Is delivery included in the quoted price?
Delivery is a separate line, not baked into the trailer rate. Get a full quote through request a quote so distance, hookup needs and duration are all priced together up front.
What is the difference between this and the 2 stall option?
Stall count changes capacity, not features. Both run interior sinks and lighting; the 2 stall restroom trailer suits smaller crews or short home projects where four stalls would sit mostly empty.
