A monthly porta potty rental in St. Louis runs $125 to $325 for a standard unit, with most jobs landing near $200. That range covers weekly service, and it beats paying a daily or weekend rate across a 30-day job. Longer projects save more per day the longer they run, which is the whole logic behind porta potty rental cost monthly pricing versus paying day by day.
Anyone searching porta potty rental cost per month near me is usually comparing a handful of local quotes, and the range below is what most of those quotes land inside.
Monthly pricing depends on unit type, how many units you need, and where the job sits. A standard porta potty rental in St. Louis falls between $125 and $325 a month, and that is the number most contractors and homeowners land on for a single-unit renovation or a fenced construction lot. Compare that to porta potty rental cost broken out by day and week, and the monthly rate almost always wins once you pass three or four weeks of use. A deluxe flushable porta potty costs more, and an ADA accessible porta potty runs $120 to $240 a week if you need one on site for compliance under ADA Standards section 213.2, which requires at least one accessible unit in any cluster of single-user toilets. Delivery adds a separate line, typically $120 to $420 a month depending on distance and access. If your site sits out toward Chesterfield, about 19.2 miles west of downtown St. Louis, or up near Florissant, 15.4 miles north, factor that drive into your delivery quote.

Long term porta potty rental cost drops on a per-day basis the same way any portable toilet rental cost per month drops once you stop paying for delivery over and over.
Because the delivery and pickup cost, which is the biggest fixed expense in a short rental, gets spread across 30 days instead of two or three. A one-day rental has to absorb the whole trip in a single use. A month-long rental splits that same trip cost across every day the unit sits on site, which is why the effective daily rate keeps dropping the longer the contract runs. Service frequency matters too. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for units seeing up to 10 users over a 40 hour week, and that weekly cadence is baked into the monthly price whether you use the unit hard or light. If you are staffing a construction crew, OSHA 1926.51(c)(1) sets the actual toilet count you need: one facility for 20 workers or fewer, one toilet seat and one urinal per 40 workers once you pass 20, and one seat and urinal per 50 workers at 200 or more. That ratio is what should drive how many units you rent, not just square footage. Run the numbers with how many porta potties do I need before you commit to a porta potty rental per month count, and check OSHA portable toilet requirements if a safety officer or GC is going to ask.
A standard unit sits on a 60 to 70 gallon holding tank, measures about 44 by 48 inches on the ground, and stands roughly 92 inches tall. Delivery, one weekly service visit, and pickup at the end of the term are typically bundled into the monthly rate, though delivery sometimes lands as a separate fee depending on drive distance. Servicing means pump-out, a fresh chemical charge, and restocked paper. If your crew is applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities on top of toilets, which is a separate rental from a handwashing station and worth adding to the same monthly order. Potable water access falls under OSHA 1926.51(a)(1) as well, so if you are running a remote site with no water hookup, pair your toilet order with a portable sink rental. For general industry sites rather than construction, toilet ratios fall under 29 CFR 1910.141(c)(1)(i) instead. Multi-unit jobs, like a construction dumpster rental paired with sanitation, often bundle better as a package quote than piecing services together separately. Ask about combined delivery when you also need a temporary fence rental or a storage container rental on the same lot.
Placement in a public right of way or on a public sidewalk in St. Louis needs confirming with the city before delivery. Permit rules vary by location and by how long the unit stays, and we have not verified a specific ordinance to cite here, so check with the city directly rather than assume. If your unit sits entirely on private property, set back from the street, permitting is less likely to apply, but confirm before the truck shows up. See porta potty permit requirements and dumpster permit requirements if you are renting a dumpster alongside the toilet for the same job. Placement also affects service access: a roll-off delivery needs about 60 feet of straight clearance behind the truck, and a porta potty needs a similar clear path for the weekly pump truck to reach it without crossing landscaping or parked cars. Review the porta potty placement guide before your first delivery so the crew does not have to reposition the unit mid-contract. Winter months change service needs too, covered in porta potty in winter.
Most standard units run $125 to $325 a month in St. Louis, with weekly service included. Actual cost depends on unit type, how far the delivery truck has to drive, and whether you need an ADA unit or a deluxe flushable model added to the order.
Yes, almost always. A weekly standard rental runs $130 to $500, and stacking four weeks individually usually costs more than one monthly contract because delivery and pickup fees get charged once instead of four times.
Standard service runs once a week under the ANSI/PSAI Z4.3 baseline for units seeing normal use. High-traffic sites, like a busy renovation near University City, 7.9 miles northwest of downtown, may need twice-weekly service, which adds to the monthly rate.
Yes. Crews often start with one unit and add more once headcount grows past the OSHA 1926.51(c)(1) threshold for a single facility. Request additional units through request a quote and delivery gets scheduled around your existing service day.
Monthly rentals bill by the 30-day term with weekly service built in, while event rentals like a wedding restroom rental or festival restroom rental are priced per event, often for a single weekend, and serviced once at drop-off.
