PolyJohn’s 300-Gallon Holding Tank is our largest holding tank and an essential piece of equipment for long-term portable restroom rentals such as an outdoor rest area or a multi-day special event. Functional, discrete, and safe, the tank gives peace of mind to the workers or guests at the location.

The 300-Gallon Holding Tank is manufactured with extremely durable plastic and features heavy-duty, thick-wall construction. It has multiple ports to accommodate any plumbing configuration you may need and is easily set up for use with rubber couplers and clamps.
