A standard porta potty in St. Louis runs about 150 dollars a day, 200 for a week, and 200 a month for a construction placement. Delivery is usually 100 to 150 dollars on top. Deluxe flushable units and ADA models cost more, and restroom trailers are a separate class entirely. When people ask how much a portable toilet rental costs, the number moves with how long you keep it and how many people use it.
The honest answer to how much a portable toilet rental costs is a range, because the unit and the rental length both matter. A standard porta potty rental is the base. A deluxe flushable unit sits higher, and an ADA accessible model higher still on a daily basis. For most jobs in St. Louis, the monthly rental is the cheapest way to keep a toilet on site because the weekly service is built into the rate. If you only need a day, look at the per-day pricing. Event customers often ask about event restroom rental instead, which is priced by the day or the weekend. Whatever the portable toilet rental is for, get the delivery fee quoted separately so you can compare rent porta potty prices vendor to vendor honestly.

Here are the portable toilet rental costs we see across the St. Louis market when you rent a porta potty here. Weekend is a premium short-term rate, so it is quoted in prose below the table, not in the day-week-month columns.
| Unit | Day | Week | Month |
|---|---|---|---|
| Standard | 100 - 350 | 130 - 500 | 125 - 325 |
| Deluxe flushable | 85 - 1200 | 150 - 290 | - |
| ADA accessible | 200 - 400 | 120 - 240 | - |
| Restroom trailer | 175 - 2500 | 150 - 1650 | - |
A standard unit rented for a weekend typically lands between 125 and 400 dollars. An ADA weekend rate runs 199 to 300. A restroom trailer over a weekend is a bigger commitment, usually 900 to 3000 depending on stall count. Full event pricing lives on the restroom trailer cost page. For the plain-language breakdown, see porta potty rental cost basics or the cost overview.
Most vendors, us included, break these out as separate lines so you can see the real total. Here is what those add-on charges look like across St. Louis.
| Fee | Week | Month |
|---|---|---|
| Delivery | 50 - 150 | 120 - 420 |
| Service | 30 - 220 | 100 - 300 |
| Pickup | included with delivery | included with delivery |
A single delivery fee covers the drop and the haul-away on most short rentals. Service is the pump-and-clean visit. Under ANSI/PSAI Z4.3, one service visit per week is the baseline for up to 10 users over a 40-hour week, so a standard weekly plan buys you one cleaning. Heavy use means more visits and a higher line. Ask about the rental checklist before you book, and if you need a fast drop, our emergency porta potty rental moves same-day. Longer jobs should read the placement guide so the truck has room.
Three things drive the price for portable toilet rental. Unit type is the first. A porta john with just a seat, one of the plainest port o potties for rent, costs less than a deluxe flushable with a foot pump and a sink. The second is rental length, and this is where people overpay. A day rate looks cheap until you keep the unit three weeks. The third is service frequency. OSHA 1926.51(c)(1) sets one toilet for up to 20 workers, then adds a seat and a urinal per 40 workers past that, so a bigger crew needs more units and more cleaning. Distance matters too. We are close in the city core but a run out to Chesterfield, 19.2 miles west, or St. Peters, 27.0 miles northwest, adds drive time to the delivery line. Tank size plays in as well: a standard unit holds 60 to 70 gallons, so how fast it fills sets your service schedule.
Construction is almost always a monthly rental with a weekly service built in. That is the cheapest per-day math you will find. Sizing follows OSHA 1926.51(c)(1): one facility for 20 or fewer workers, then one toilet seat and one urinal per 40 workers as the crew grows. Our OSHA portable toilet requirements page walks the full table, and the how many do I need calculator does the arithmetic for you. Most St. Louis jobsites pair the toilet with a handwashing station, which 29 CFR 1910.141(d)(2) effectively requires because soap and towels have to be present and hand sanitizer alone does not satisfy it. Bundle it all under construction site services and you can add a roll-off dumpster or a storage container on one delivery. Big crews should also read the dumpster weight limits page.
A fair quote names every line, not one lump number. It lists the unit type, the rental length, the delivery fee, the service frequency and the pickup. If a vendor gives you a single figure and will not itemize, you cannot compare it to anyone else. Ask whether the weekly cleaning is included or extra. Ask what a herbicide or paint crew needs, because OSHA 1926.51(f)(1) requires washing facilities where workers apply paints, coatings, herbicides or insecticides, and that is a separate line item. For event work, confirm the event restroom count against your headcount. A wedding with 150 guests is not the same as a festival with 5,000, so what it costs to rent a portable restroom shifts with the count. If you want the plain monthly math, or a per-day figure, we will put it in writing. Get it from St. Louis Porta Pros and compare it line by line.
Here are three worked scenarios so the numbers feel real. Each uses the bands above, not a made-up quote.
Weekend backyard party, one standard unit. One standard porta potty for a Saturday-Sunday event in the St. Louis city limits lands around 125 to 400 for the weekend, plus a delivery fee of 125 to 200. One drop, one pickup. Add a portable sink if you are serving food.
Home remodel, four weeks. A home renovation porta potty kept a full month runs in the 125 to 325 range for the unit with weekly service, plus a monthly delivery line of 120 to 420. Cheaper per day than any short rental. Pair it with a 10 yard dumpster for the debris.
Mid-size jobsite, 30 workers. That crew needs two units under OSHA 1926.51(c)(1). Two standard units on monthly service, plus a handwashing station, is the typical build. Run it through how many porta potties do I need to confirm.
We deliver across the St. Louis metro and the drive shows up in the delivery line, not the unit rate. Close-in towns barely move the number. University City is 7.9 miles northwest and Webster Groves is 8.6 miles southwest, both short runs. Kirkwood at 12.5 miles west and Granite City at 12.1 miles northeast add a little. Florissant, 15.4 miles north, and Belleville, 18.8 miles southeast, are still same-day for us. See the full service areas map for the reach. Placement in a public right of way is a separate question. Permit rules are NOT VERIFIED for St. Louis, so confirm any right-of-way placement with the city before you book, and read the permit requirements page for what we do know. For septic pumping or a holding tank, distance works the same way.
If you want to rent a porta john or rent a porta potty for the least, the lowest entry point is a standard unit on a monthly plan, which starts near 125 dollars plus delivery. Short daily rentals look cheaper up front but cost more per day of use. Get a written quote to see the real total.
No. Delivery is almost always a separate line, from 50 to 150 on a weekly rental and 120 to 420 monthly. That fee covers both the drop and the haul-away. See the fee table above and confirm it on your quote before booking.
One service visit per week is the baseline under ANSI/PSAI Z4.3, sized for up to 10 users over a 40-hour week. Heavier use needs more visits. Our cleaning frequency page explains the schedule, and do porta potties smell covers why service matters.
If you serve the public, yes. ADA Standards 213.2 require at least 5 percent of clustered units, never fewer than one, to be accessible. An ADA unit runs higher per day than standard. The ADA requirements page has the full spec.
A porta potty is a single unit priced in the low hundreds. When people ask how much a portable toilet rental costs against a trailer, the restroom trailer is multi-stall with flushing toilets and runs from 175 a day to a few thousand for an event, so the port o john rental is the cheaper of the two. Compare a 2 stall against a 4 stall on the trailer cost page.
A single standard unit for one day falls in the 100 to 350 range plus delivery. Event-day pricing can run higher for peak weekends. Size the count against your guest list using the how many do I need guide first.
Yes. Weekend rates are a premium short-term price, roughly 125 to 400 for a standard unit and 199 to 300 for an ADA model, delivery separate. It is common for festival and concert work. Book early through St. Louis Porta Pros.
