The Sun-Mar Compact Self-Contained Composting Toilet is an elegant, low-profile unit with the looks to complement any bathroom. The patented variable diameter Bio-drum is small at the front and large at the rear, with a recessed handle for mixing and aerating the compost.
The Sun-Mar Compact differs from the Sun-Mar Excel in that all three chambers are smaller, which makes the Compact ideally suited to light residential use (1-2 people) or light to medium cottage use (3-4 people). Includes a 2" vent stack that attaches to the rear. A ¾" (outer diameter) emergency drain at the rear offers protection against heavy or residential use or prolonged power outage.
