About PolyJohn Tanks

PolyJohn is a leading manufacturer of holding tanks and recirculating flush tanks. Our tanks set the standard for the sanitation industry and are used worldwide. Crafted for maximum durability, our tanks ensure waste is stored safely and discreetly.

We manufacture a diverse lineup of holding tanks and recirculating flush tanks. Our holding tanks are a necessity at long-term construction sites or outdoor rest areas where indoor plumbing isn’t available. They are specially designed so that they can be used with many of our portable toilet or sink models interchangeably. Our recirculating flush tanks are operated by foot pumps or hand levers and conceal waste with a weighted flapper valve, providing enhanced user experience.
