Mr. John has been a top provider of portable restroom solutions to the construction industry since 1964. We handle all types of jobs including residential, commercial, industrial, highway, and remodeling projects. Our clean, modern equipment can be conveniently located to yield labor and cost savings while maintaining a sanitary work environment.

Portable sanitation affords significant labor savings by minimizing lost labor time associated with leaving the site to use toilets. The average time needed to make an offsite restroom usage is 7 minutes including travel time. Portable toilets can be easily relocated and can follow the workers as projects progress, providing flexibility and increased labor savings.

Our clean, modern equipment can be placed in locations that yield labor and cost savings while maintaining a sanitary work environment.

In “Provision of Sanitation Facilities at Construction Sites,” a study done by the University of Missouri-St. Louis, contractors earned an 850% return on their investment in portable toilet facilities.
