The Free Standing Sink, TJ-Junior, and the TJ-Handy Stand are the toughest portable sink systems available in the industry. They are constructed of 3/16″ polyethylene making them durable yet light enough to be moved anywhere needed. The newest addition to our Tuff Jon line-up is the TJ-Junior.  This unit was designed with maneuverability in mind, comes with large wheels, a built-in handle and can be moved anywhere with ease.
