Signature Series


The Signature Series from PolyJohn features the enhanced hygiene and performance amenities ideal for special events. The Signature Series starts with the same specially formulated polyethylene used in our PJ III and Fleet Series models. However, the Signature Series is loaded with progressively designed features that make all the difference in comfort and convenient maintenance. The ventilation system is discreetly hidden to maintain the integrity of the design, yet allow air to flow freely throughout the unit. A rain gutter built into the door frame eliminates cascading water when the door is opened. Inside, we’ve eliminated the urinal, and projected the toilet bowl out over the tank to make it more user friendly. And unequaled in hygiene. Depending on your requirements, there are three Signature Series models to fit your needs-including the City Mains unit which ties in directly to municipal sewers and fresh water lines; the Fresh Flush unit and Recirculating Flush.
