The Axxis portable restroom from PolyPortables has self-closing hinges that operate from an internal stainless steel spring, a heavy-duty rotary latch that is tough enough for hard use, a deep ambidextrous door pull for convenience and a durable door frame for maximum structural integrity. It comes with a 60-gallon waste tank, rotationally molded plastic skid, urinal, coat hook and a three-roll toilet paper holder. 800/241-7951; www.polyportables.com.
