Sun-Mar Excel Composting Toilet

SUN-MAR Composting Toilets are designed to harness, optimize and accelerate the natural processes of decomposition and evaporation to convert toilet waste (which is 90% water) into a useful, nutrient-rich fertilizing soil. Sun-Mar units are economical, quick to install and easy to use and are perfect for cottages, pool houses. any facility without facilities!

A SUN-MAR Composting Toilet can replace a conventional flush toilet that's attached to a poorly working septic system, can offer the luxury of an indoor facility where there is only an outhouse; and is the right environmental choice for cottages, homes "off the grid" or other locations with no toilet at all.

Because no chemicals and no septic systems are used, fragile environments can be protected. The SUN-MAR system produces no pollutants, while collecting nutrients. With a SUN-MAR, recycling is made easy!

The SUN-MAR Excel is the best-selling composting toilet in North America and for good reason. It is a high capacity Bio-drum unit 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 a SUN-MAR Excel, you are literally purchasing a composting toilet that sets the standard.

The Excel is the preferred self-contained electric model for heavy or residential use. Composting speed and capacity on this model is outstanding! The large Bio-drum™ designed into the Excel gives it twice the capacity of the Compact model. The Excel has sufficient capacity that it can be used just about anywhere - in residences, cottages and even in light commercial applications. The Excel was tested by the National Sanitation Foundation (NSF) at maximum capacity for 6 continuous months (to simulate residential use), during which time it produced a clean, safe compost, with no odor. SUN-MAR self-contained units are the only ones listed by the NSF for residential and cottage use (their Standard #41 is the toughest composting performance standard in the world).

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. Although the Excel can normally evaporate all liquids, a 1/2" emergency drain is fitted at the rear, and should be connected for heavy or residential use, or if prolonged power outages are expected.

Composting Capacity: Residential & Continuous 3/5, Weekend & Vacation 6/8.
