What Types of Portable Restrooms Can I Rent?
Start with the standard portable restroom rental if you're covering a job site or a backyard build. It's the workhorse: a 44 by 48 inch footprint, about 92 inches tall, built to handle daily traffic without drama. If guests are dressed up and expect a flush, step up to the deluxe flushable porta potty, which is what most people mean when they ask about a portable restroom rental for party use. Need something for a wide event or a crew with mobility needs? ADA accessible porta potty units meet ADA Standards 213.2, which requires that at least 5 percent of a cluster of single-user units be accessible, with a minimum of one, and the units themselves are built around a 60 inch turning circle per ADA 304.3.1. For bigger footprints, the restroom trailer rental line covers everything from a compact 2-stall portable restroom trailer to a 4-stall restroom trailer or an 8-stall restroom trailer for larger crowds. If someone's searching portable restroom trailer rental near me and wants the nicer end of that lineup, the luxury restroom trailer has finished interiors, running water and climate control, closer to what a wedding venue expects than what a job site needs. We also field calls occasionally referencing a portable restroom trailer rental Michigan or portable restroom rental Cape Coral company; we're a Saint Charles, MO operation, so we can only speak to what we run locally.
How Much Does Portable Restroom Rental Cost in Saint Charles?
Pricing depends on unit type, rental length and how far the delivery truck has to go. Here's the range we see across standard units, ADA units and trailers:
| unit | day | week | month |
|---|---|---|---|
| standard | $100 - $350 | $130 - $500 | $125 - $325 |
| ada | $200 - $400 | $240 - $500 | -- |
| deluxe | $85 - $1200 | $150 - $290 | -- |
Trailers run separately since they scale with stall count and finish level; a weekly trailer rental can land anywhere from $150 to $1,650 depending on size. For a single weekend event, expect a flat weekend rate rather than a daily multiple. Delivery fees are usually added on top and depend on distance from our yard. For a deeper breakdown by rental length, see porta potty rental cost, porta potty rental per day, or monthly porta potty rental if you're planning a longer project. Trailer-specific numbers live on restroom trailer rental cost.
How Many Units Do I Need for My Site or Event?
OSHA 1926.51(c) sets the baseline for construction sites: one toilet facility for 20 or fewer workers, then one toilet seat and one urinal per 40 workers once you pass 20, dropping to one per 50 workers at 200 or more. That's the number an inspector will check against on a job site in Saint Charles, so it's worth getting right before crews show up. Event planners don't answer to that table directly, but the logic scales the same way: more heads, more units, plus a buffer for peak-hour lines. ANSI/PSAI Z4.3 sets the baseline service interval at once per week for up to 10 users over a 40-hour week, which is useful for planning how often we'll need to swing by during a multi-week rental. If you're unsure how many stalls a wedding, festival or job site actually needs, how many porta potties do I need walks through the math, and OSHA portable toilet requirements covers the construction-specific rules in more depth. Placement matters too: units need firm, level ground per ADA Standards 302.1, and a clear 36 inch route per ADA 403.5.1 if anyone using a wheelchair needs to reach the door. Our porta potty placement guide covers where units can and can't go on a typical lot in Saint Charles.
Can I Rent a Portable Restroom for a Single-Day Event?
Yes, single-day and weekend rentals are common, especially for weddings, block parties and one-day festivals in Saint Charles, MO. A weekend rental typically runs as a flat rate rather than stacking daily charges, which usually works out cheaper than renting by the day for a two or three day stretch. If you're planning something bigger, event restroom rental, wedding restroom rental and festival restroom rental all cover event-specific setup, and marathon and race restrooms and golf tournament restrooms handle the spread-out, high-traffic layouts those events need. Need something same-day because a rental fell through? Emergency porta potty rental exists for exactly that. Customers as far as St. Peters, 6.9 miles west, and Maryland Heights, 9.4 miles southeast, still fall inside our normal delivery radius, so distance rarely rules out a same-week booking.
How far in advance should I book a portable restroom?
Two to three weeks is comfortable for weekend events; job sites with recurring service can usually be set up within a few days. Peak wedding and festival season books faster, so if your date's already picked, get on the schedule early rather than waiting.
Do portable restrooms need a permit in Saint Charles?
Placement in the public right of way needs confirming with the city before delivery. On private property it's usually straightforward, but we'd rather check than guess. See porta potty permit requirements for what to ask about before your date locks in.
What's the difference between a standard unit and a restroom trailer?
A standard unit is a self-contained single stall with a holding tank underneath. A trailer has multiple stalls, running water and often flushing toilets, closer to a real bathroom. Trailers cost more but suit weddings and staffed events better than a row of standard units.
Do you deliver outside Saint Charles?
Yes. We regularly serve Hazelwood, 8.5 miles east, and Florissant, 13.9 miles east, along with Chesterfield, 17.1 miles south. Check service areas for the full list, or request a quote with your address and we'll confirm delivery.
Can I get a portable sink or handwashing station with my order?
Yes, most orders can add a handwashing station rental or portable sink rental alongside the restrooms. 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at wash stations, not just sanitizer, which is worth knowing if you're outfitting a job site rather than a party.
