How to Request Your Quote
Call or fill out our online form with the basics: job type, number of units, rental duration and setup date. Whether you need a standard porta potty for a construction crew, a deluxe flushable unit, or an ADA accessible portable restroom, we'll match equipment to your crew size. OSHA 1926.51(c) sets the baseline: 1 toilet per 20 workers on a construction site. Tell us your headcount and we'll tell you how many units fit the code. Saint Charles Porta Pros serves all of Saint Charles, plus St. Peters at 6.9 miles west and Hazelwood at 8.5 miles east. Placement in the public right of way needs confirming with the city, so mention your site layout and we'll flag any permits you'll need to pull.
What Information Helps Us Quote Faster
Event dates matter most. A weekend rental runs higher than a weekday one because demand peaks Friday through Sunday. Give us your setup date and takedown date and we'll lock in your rate. Let us know if you need services beyond the unit itself: restroom trailer rental for an event, roll-off dumpster rental for demolition or renovation, storage container rental for tools, or temporary fence rental for a site perimeter. A standard unit sits about 44 by 48 inches on the ground, so confirm you've got the space. Maryland Heights is 9.4 miles southeast and Florissant is 13.9 miles east; if your site is beyond our service area, we'll tell you upfront. Septic pumping and grease trap pumping quotes work the same way: tell us tank size and last service date and we'll price it.
Quote Timeline and Next Steps
Most quotes arrive the same business day. After you submit details, our team reviews your job specs and sends a price breakdown via email or phone, whichever you prefer. If you need handwashing station rental for a crew applying paints, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities with soap and towels, so we'll factor that in. Once you approve, we schedule delivery. A roll-off dumpster rental needs roughly 60 feet of straight clearance behind the truck, so confirm site access before we book. Saint Charles Porta Pros keeps an inventory on hand so same-day and next-day delivery is standard. Your quote includes pickup, so no surprises at the end. Ready?

What's included in your quote?
Your quote covers rental, delivery, weekly service if booked longer than one day, and pickup. Mileage within Saint Charles and nearby areas is included. Ancillary fees, such as service charges for events or weekend surcharges, appear as a line item on the estimate before you confirm.
Do you service areas beyond Saint Charles?
Yes. We deliver to St. Peters, Hazelwood, Maryland Heights, Florissant and Chesterfield. Travel beyond our core service zone may carry an additional fee. Give us your address and we'll quote it.
How do I know how many units I need?
OSHA 1926.51(c) specifies minimum toilet counts by crew size. Email your headcount and job type and we'll calculate what's required. For events, we size by expected attendance and duration.
Can I rent multiple services at once?
Yes. Many sites need portable toilet rental, dumpsters, fencing and deluxe flushable units together. One call, one quote, one invoice. Bundle rentals often net better rates.
What if my event date changes?
Call us with the new dates. We'll re-quote it at no charge. Changes up to 48 hours before delivery are usually free; check your agreement for any penalties.
