Centrex 1000 Overview

The CENTREX 1000 composting toilet model is a regular capacity model ideal for those who have electricity and want a unit for a light seasonal usage. Using an ultra-low water flush toilet, the Centrex 1000 composting toilet can provide an ideal combination of capacity and comfort.

The 1000 has a built-in heating element and fan assembly. All 1000 series composting toilets are supplied with a 1″ drain hose, which should be connected in all applications. The Centrex 1000 is designed to be used when you have space for the composter away from the toilet.

Installations include, but are not limited to: cabins, cottages, homes, businesses, resorts, camps, treehouses and workshops. The CENTREX 1000 series is designed for use with the 1 pint flush toilets (purchased separately).

Our cabin is on a hillside, lots of rock and gravel. No place to put a septic system, even if we wanted one.

The ultra low-water flush toilet has a straight drop to the Centrex 1000 in a insulated, heated containment unit under the floor. A flip up door allows for turning the crank without total loss of heat for winter use, very dry year, lots of drywells, doesn’t worry us. The environment office suggested a compost unit when I called for a site inspection.

CENTREX 1000 sits behind lattice that easily lifts off for access

The unit works very well and I extended the season by heating the air through a 3″ intake duct on a thermostat.

We purchased a Sun-Mar Centrex 1000 for our island camp in eastern Maine which has been happily established and composting

Since we were so pleased with that one, and feeling we needed to provide additional toilet facilities for larger groups visiting, we have installed this summer a new Sun-Mar Excel. This self-contained unit has gone into another small cabin adjoining a kitchen and bedroom.
