Sun-Mar Centrex 2000 Central Composting Toilet System


This item requires a custom freight quote. After your order is placed, we will contact you with shipping rates and will complete your order upon your approval.

Perfect for medium to heavy seasonal or light residential use, the Sun-Mar Centrex 2000 Central Composting Toilet System allows for both a longer composting cycle and larger waste volumes than the Centrex 1000. The increased surface area in the evaporating chamber, coupled with the larger heating element, provides excellent evaporation.

When used seasonally by families of up to 9 (7 adults), compost will normally only need removing in the spring. When used residentially by families of up to 6 (4 adults), some compost will need to be emptied into the finishing drawer once every few months.

The Centrex 2000 features a 370-Watt thermostatically controlled heater in a sealed compartment under the unit, a 30-Watt fan, and a 2" vent stack to remove evaporating liquid and fresh odors. Includes a 1" drain hose that should be connected to the 1" drain at the bottom of the unit.


Low-Flush or Waterless?

By default, the Centrex 2000 is designed for use with one or more Sun-Mar Low-Flush Toilets (available separately above).

To make the system waterless (dry flush), use the Sun-Mar Waterless Kit and one or more Sun-Mar Dry Toilets (available separately above).

Everything for installation and start up, including the vent stack, is included.
