Portable restrooms in Georgia are not so sweet. Portable restrooms are mobile restroom trailers that are also used as dressing rooms & cast trailers, wardrobe and hair & makeup facilities while filming on location. Legend has it that honeywagons units are so named because of the "honey-colored" liquid that comes out of them when draining the holding tanks. Portable restrooms range in size from single stalls to units with multiple stalls and showers. Portable restrooms offer the comforts of home while working on motion picture and television production.
