The Tufway portable restroom from Satellite Industries is made of high density polyethylene to withstand constant handling and transport, with durable corner construction and a UV-resistant roof that will not yellow or become brittle. It comes with molded-in air vents, a one-piece, unbreakable urinal, 70-gallon waste tank and a standard door hook. The seat is angled away from the urinal, the domed floor doesn’t puddle and the sumped tank quickly hides waste. 800/883-1123; www.satelliteindustries.com.
