The Excel is the best-selling unit in North America and for good reason. It is a high capacity Bio-drum toilet that is very simple to operate, features well proven technology and is extremely reliable. The Excel was the first ever self-contained composting toilet to be certified by the National Sanitation Foundation (NSF). So, when you purchase an Excel, you are literally 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.

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 odour and produced a clean, safe compost. Only Sun-Mar self-contained units are listed for residential and cottage use by NSF, whose Standard #41 is the toughest composting performance standard in the world.

The 2" vent is attached at the top back of the Excel and can be installed invisibly by running it through the wall and up the outside wall. For comfort the Excel has a sturdy detachable footrest which can be removed to pull out the finishing drawer.

In normal use the Excel can normally evaporate all liquids, however a 1" emergency drain is fitted at the rear and this should be connected if the unit is to be used residentially or heavily, or if prolonged power outages are expected.

SUN MAR Products do NOT have free shipping and require a ship quote. There is also a very long lead time currently.
