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.
While the Sun-Mar Compact is plumbing-free like the Sun-Mar Excel, it differs from the 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.

About Sun-Mar Composting Toilets

Everything for installation and start up, including the vent stack, is included. Great for use in homes, cottages, weekend cabins, pool houses, barns, stables, workshops, or off-grid applications - anywhere you want to minimize your ecological footprint.
