The Sun-Mar Compact is a low-profile electric composting toilet, rated for 1 adult in residential use and 3 adults or a family of 4 in weekend and vacation use.

It plugs into a standard 110 V outlet and needs a steady power supply. Its patented Bio-Drum is small at the front and large at the rear, and the handle that turns it sits recessed in the body. The 2 in vent stack can be hidden, and a 3/4 in emergency drain at the rear protects against heavy use or a long power outage. It's certified to NSF/ANSI Standard 41.

Sun-Mar has made composting toilets for more than 40 years, from offices in Stoney Creek, Ontario, and Tonawanda, New York.
