 Sun-Mar Centrex 1000 Composting Toilet Electric

The Centrex 1000 model is ideal for those who have electricity and want a unit for a light seasonal application.


In light to medium seasonal use the Centrex 1000 is typically able to hold compost for the full season, and compost needs extraction only in the Spring.



The Centrex 1000 features a 260 watt heater in a sealed compartment under the unit and the standard Sun-Mar 25 watt turbo fan and 2″ vent stack to ensure odorless operation.



All 1000 series units are supplied with a 1″ drain hose which should be connected to the 1″ drain at the bottom left of the unit. Click here for more information on handling excess liquid.



The 1000 series is designed only for use with 1 pint flush toilets (purchased separately).
