Sun-Mar Excel - Self-Contained Toilets

The Excel is Sun-Mar’s best selling unit in North America, and for good reason. It is a high capacity Bio-drum™ toilet that is simple to operate, features proven technology and is extremely reliable. The Excel was the first ever self-contained toilet to be certified by the National Sanitation Foundation (NSF). So, when you purchase an Excel, you are purchasing a composting toilet that sets the standard. The Excel has enough capacity that it can be used just about anywhere; in residences, cottages and even in light commercial applications.
