Portable Toilet Rental FAQs

What areas do you serve?

We're based in O'Fallon, MO and serve the surrounding St. Charles County area, including Lake Saint Louis, Wentzville, St. Peters, Dardenne Prairie, Cottleville, Weldon Spring, and greater St. Louis.

How quickly can you deliver a portable toilet?

Delivery timing depends on your date, unit type, and quantity. Contact us with your details and we'll confirm the earliest available delivery window for your job site or event.

Do I need to be on-site for delivery and pickup?

Not necessarily — many customers coordinate placement in advance by phone or email and don't need to be present for delivery, as long as our team has clear site access instructions.

What's the difference between your unit types?

Standard units are our reliable, no-frills workhorse. Deluxe units add a foot-pump flush and sink. ADA-accessible units offer wider doors and grab bars. Restroom trailers provide climate-controlled, running-water comfort for upscale events. Visit our Services page to compare all eight options.

Do you offer emergency or short-notice service?

Yes — see our 24/7 Emergency Service page for urgent swap-outs, storm-related issues, and short-notice requests.
