Long considered the standard in composting toilet performance, the EXCEL is the preferred self-contained electric model for heavy or residential use. Composting speed and capacity on this unit is outstanding! The large Bio-drum engineered into the Excel gives it twice the capacity of the Compact.
The Excel has been successfully tested by the National Sanitation Foundation for six continuous months at its maximum residential capacity of four adults. Key criteria were that the unit operated odorlessly, and produced a clean dry compost. For weekend and vacation use the capacity is 6-8 people, and even these numbers can be doubled for short periods.
The 2" vent is attached at the top rear of the unit and can be installed invisibly by running it through the wall and up the outside wall. For comfort, the Excel has a detachable footrest which can be removed to pull out the finishing drawer.
