Construction Restroom Rentals

Portable Restrooms | Hook Restrooms | High Rise Restrooms | Fresh Flush Systems

On Site Companies knows everything there is to know about portable sanitation for construction sites. We offer a wide range of porta potties and portable hand wash sinks for rent in a variation of different styles and functions. From our standard construction unit, to our specially designed high rise unit, we can provide your job site with all of the equipment that you need to keep your work area clean and comfortable. All of our portable toilet solutions are available for rent in the Minneapolis/ St. Paul, Mankato, Rochester, and Duluth Minnesota areas as well as St. Louis, Missouri. The chart below highlights the general usage guidelines of how many units your site will require. You can even upgrade your cleaning services from once a week to twice a week if your work load changes.

OSHA Compliant

Per OSHA standards, employers with 20 or fewer employers must provide one toilet to their workers. Employers with 20 or more employees must provide one toilet and one urinal per 40 workers. If an employer has 200 or more employees, one toilet and one urinal is required for every 50 employees.

Increase Productivity

Neglecting to provide portable restrooms for your construction workers can easily decrease productivity. If you don’t provide portable restrooms for your workers, they’ll have to leave the job site to use a restroom at a nearby business or convenience store.

Clean and Sanitary

To ensure optimal restroom cleanliness and sanitation, porta potties utilize unique chemicals that quickly break down waste and kill bacteria and germs.

Proper Waste Disposal

All of our portable restrooms are properly serviced, with all waste disposed of in an environmentally-friendly way, according to all laws and regulations.

Easy to Arrange

Portable toilets are small and easy to arrange. This makes them ideal for spaces where you need as many toilets as possible. You’ll be able to fit more units in a small space, giving your guests the convenience of not having to wait in line.

Standard Construction Restroom

Our Standard Construction Porta Potty is our most popular portable restroom for construction sites. This restroom is built with sturdy materials that are designed to withstand the tough day-to-day life on a construction site. All of our restrooms are delivered clean and graffiti free.


Mobile Portable Restroom

Our Mobile Restroom for construction sites and road construction. This restroom can easily be hooked up to a trailer hitch and be moved to a new location quickly. The mobility of this porta potty makes it perfect for road construction and golf courses.


ADA Portable Restroom

ADA Portable Restrooms feature hand rails and larger spaces to accommodate guests that may need the extra space and amenities.


Hook Unit Portable Restroom

Our Hook Unit Restroom is simply our standard portable restroom with additional portability. This restroom can be attached to a crane to be easily moved from one area of the construction site to another, and also to be placed on multiple story buildings.


High Rise Portable Restroom

The High Rise Portable Restroom is designed to easily reduce in size in order to fit into small high rise elevators during construction. Unlike our hook restroom unit, this restroom can be rolled to any part of a high rise construction site, and then brought down for service through a service elevator.


Fresh Flush Mobile Office

The Fresh Flush Mobile Office is a system that hooks up to the restroom that is built into your job trailer on site. The fresh flush can be paired with our hot water SaniSink hand washing system to provide a more traditional restroom experience to your workers and site guests.
