Sun-Mar Excel NE Non-Electric Self-Contained Composting Toilet

Running water and electricity isn?t always an option, but that doesn?t mean you can?t have a functional toilet. The Sun-Mar Excel Non-Electric Composting Toilet is a stand-alone system that can be used in even the most remote locations. The toilet uses the natural process of decomposition and evaporation to convert human waste into a useful fertilizing soil. Odorless operation is achieved by a 4' vent mounted at the top rear of the unit which acts like a chimney on a wood stove.
