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.

The Excel is available in two colors – white and bone.
