"Porta john" is just another name for a portable toilet, and St. Louis Porta Pros rents them by the day, week or month, with standard units starting around $100 a day. Whether you call it a porta john, a porta potty or a portable restroom, the unit and the service are the same.
Price depends on how long you need it and what kind of unit you want. A standard porta potty rental runs a wide band because job sites, weekend parties and month-long projects all pull from different ends of that range. If you want flushable features, a deluxe flushable porta potty costs more but feels a lot less like camping. ADA units, required whenever you have a mixed crowd or accessible parking nearby, sit in their own price tier too. Here is what the numbers actually look like across duration and unit type in the St. Louis market.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $240-$400 | - |
| deluxe | $85-$1200 | $150-$290 | - |
Delivery is billed separately, typically $100 to $150 for a single-day drop and less per visit if you're renting for a week or a month. For a deeper breakdown, see our porta potty rental cost page or check porta potty rental per day pricing if you only need one for a weekend project in St. Louis.
OSHA 1926.51(c)(1) sets the baseline: one toilet for every 20 construction workers on a crew of 20 or fewer, then one toilet and one urinal per 40 workers once you pass that threshold, dropping to one per 50 once you hit 200 workers. That's the rule St. Louis contractors get checked against, and it's worth reading in full on our OSHA portable toilet requirements page before you order. Farms and agricultural operations follow a different standard: OSHA 1928.110 calls for one facility per 20 hand-labor employees, reachable within a quarter mile walk, which matters if you're staffing a spread-out property. Event organizers should size differently again; our how many porta potties do I need guide walks through headcount math for weddings, festivals and races. If your crowd includes wheelchair users, ADA Standards section 213.2 requires at least 5 percent of clustered units to be accessible, never fewer than one, so a porta john rental order for a mixed-use site in St. Louis almost always needs at least one ADA unit mixed in.
Yes, and it's not the same product as a standard unit. A luxury porta john rental usually means a flushable, self-contained restroom, sometimes with a sink and interior lighting, priced closer to the deluxe tier or, for real trailer-style comfort, moving into restroom trailer rental territory entirely. For weddings and corporate events in St. Louis, a luxury restroom trailer or a 2 stall restroom trailer gets you climate control and multiple stalls instead of one unit. Trailers run from a few hundred dollars a day up into the thousands for a full weekend event package, so match the unit to the guest count rather than the label. A standard unit's holding tank runs 60 to 70 gallons and the unit itself stands about 92 inches tall on a 44 by 48 inch footprint, useful numbers if you're mapping out placement near a tent or a dance floor. If you're planning a larger gathering, our event restroom rental and wedding restroom rental pages break down what upgrades make sense.
Placement in the public right of way needs confirming with the city before delivery day, since permit rules vary by location and we don't have a blanket answer for every St. Louis address. Setting a unit on your own property or a private construction lot is usually simpler, but if you're putting one near a sidewalk, street or shared lot, check with the city first. Our porta potty permit requirements page covers what to ask about, and dumpster permit requirements is worth a look too if you're renting a roll-off alongside your toilets, since a lot of St. Louis job sites order both together. For placement details like ground clearance and accessible routing, ADA Standards section 403.5.1 requires a 36 inch clear width on any accessible route, and section 405.2 caps ramp slope at 1:12, both relevant if you're setting an ADA unit on uneven ground. See our porta potty placement guide for the full walkthrough.

Anywhere from a single weekend to several months. Daily and weekend rentals suit parties and short projects; monthly terms suit construction. See monthly porta potty rental for long-term pricing, since the per-day cost drops significantly the longer you commit to a unit.
Yes. ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users across a 40 hour week, though busier sites need more frequent pumping. Read how often are porta potties cleaned for a full schedule breakdown.
A porta john is a single stand-alone unit; a trailer has multiple stalls, often with running water and flushing toilets. Trailers cost more but suit weddings and larger crews. Compare options on our portable restroom rental page.
If workers are applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities on site. Most standard rentals include hand sanitizer, but a separate handwashing station rental satisfies that requirement more fully.
