The St. Louis Sanitation & Restroom Experts

Local. Reliable. Professional.

Large construction project. A party. A marathon. These are just some of the every day places that need reliable and professional temporary restrooms. Each situation is unique. A small party may only need a single porta potty and a handwashing station for a day, where as a construction site might need multiple restrooms for weeks with regular servicing. Or maybe a porta potty isn’t what you had in mind for your outdoor wedding and you’re looking for a restroom trailer.

Whatever your sanitation needs are, you’re going to want a reliable team of local professionals to make sure you get the right solution for your event or project.

The Right Unit For You

On Site has a variety of units to make sure you get the temporary restroom that’s best for you and your project. From a standard construction unit, to hook units that can move raised or lowered to different floors of a project, to fresh flush systems and trailers, whatever is best to keep your crew working, we have.
