Mr. John offers a variety of portable hand wash sinks as well as shower facilities.   The Porta Rain line of portable showers ranges from a self contained single stall shower unit which can be used poolside to a lavish, VIP shower trailer for bathroom renovation.  Our Sani-Wash hand wash stations and Steri-Wash hand sanitizers are a perfect compliment to any temporary restroom requirement, especially for sites where food is being served.
