This high-capacity composting toilet is simple to operate, with proven technology and reliability. “High-capacity” is actually enough to make this unit suitable for residences, cottages and lighter commercial purposes, one of many reasons why this is the best-selling unit in North America. Detachable footrest included.

From Sun-Mar: “To simulate residential use, the Excel was tested by the National Sanitation Foundation (NSF) at maximum capacity for 6 continuous months, during which the Excel produced no odor and produced a clean, safe compost. Only Sun-Mar’s self-contained units are listed for residential and cottage use by NSF, whose Standard #41 is the toughest composting performance standard in the world.”
