The SUN-MAR Excel is a high capacity, electric, self-contained unit. It is ideally suited for heavy cottage or residential use. Like all SUN-MAR toilets, the Excel incorporates a patented Bio-drum which can be easily rotated and ensures a fast, odorless decomposition. The electrical features on the Excel are a thermostatically controlled heater in the base of the unit to assist with evaporating liquids, and a fan in the top rear which maintains a partial vacuum on the unit. It does this by drawing air in over the evaporating chamber and up the vent stack The Excel saves thousands of gallons of water while recycling waste into soil. Like all SUN-MAR self-contained units, the Excel is easy and quick to install. This makes it ideal for cottages, cabins, pool houses, barns, greenhouses; in fact anywhere you need a toilet. An optional dual electric and non-electric configuration is available for this unit. It requires the separate purchase of the Sun-Mar AC/DC kit.

Rated 4.5 out of 5 by 4 reviewers.
Rated 5.0 out of 5.0 by So far so good... This is a brilliant product which meets our needs. The ability to operate a toilet without running water is phenomenally convenient. The toilet is odorless, the hum of the fan isn't as obnoxious as we had expected it to be and the required steps for maintaining the correct balance in the drum are not complicated. The toiled does require a fairly high step up which might prove difficult to persons of limited mobility or height, but that is a small price to pay when compared to all of the pros.

Rated 4.0 out of 5.0 by Nice Nice composting toilet, easy to install, seems to work well. Bought an oversized one for the usage...time will tell if that was worth it. August 19, 2014
Rated 4.0 out of 5.0 by With knowledge works out okay The composting toilet is what it is. In order to make compost you have to have the action to make it work this has it. But for comfort one thing is missing is the proper size step up to make it comfortable to reach the height needed to be relaxed I personally built a better step up for ours now every thing out just fine. I. Think in the long run this will fit our needs. June 25, 2013
