Perfect for medium to heavy seasonal or light residential use, the Centrex 2000 composting toilet system allows for both a longer composting cycle, and larger waste volumes than the 1000 systems.
The increased surface area in the evaporating chamber coupled with the larger heating element also provides better evaporation on electric units. When used seasonally by up to 7 adults, compost will normally only need removing annually each spring. In residential use compost will have to be extracted more frequently.
When used residentially by up to 4 adults, some compost will need to be emptied into the finishing drawer once every few months. The Centrex 2000 system features a 370 watt thermostatically controlled heater in a sealed compartment under the unit and the standard Sun-Mar 35 watt turbo fan, with a 2″ vent stack to remove evaporating liquid and fresh odors. The Centrex 2000 system is supplied with a 1″ drain hose which should be connected to the 1″ drain at the bottom of the unit.
The Centrex 2000 system may be used with one or more of the Ultra low flush toilets, purchased separately. This system can be converted to an AC/DC system using the AC/DC kit, purchased separately. Installations include, but are not limited to: cabins, cottages, homes, businesses, resorts, camps, treehouses and workshops.
The Centrex 2000 system is certified by the National Sanitation Foundation (NSF) to Standard 41. Click here to view a list of Sun-Mar’s NSF certified products.

After 10 years of faithful service, it was time to retire our WCM
We had been “stretching” the limits of the design – with a little more traffic than it was intended to handle. Since it had come to be in nearly continuous use, we always had to consider the WCM composter limitations when having guests visit. The answer was to upgrade to a Centrex 2000, which has added capacity, and can handle all the traffic we expect.
We are thrilled with our Centrex 2000
As our cottage is built on rock, a septic system would have been very expensive. The Sun-Mar system is much more affordable and environmentally friendly, which is important to us.
The township inspector gave it the “thumbs up”
We are really pleased with our compost toilet. (We have the one pint flush). Easy to install, very little maintenance and no problems so far.
Over the years we tried propane and chemical toilets and neither worked.
We installed the Centrex 2000 last summer in our cottage in Minaki, ON. We are so pleased with the composting toilet. It is great.
We have absolutely no regrets!
Being an island cottage owner, the Centrex 2000 works great. We have had it in operation for 2 summers now and the system has worked extremely well. We have recommended the system & now there are several more installed on our island.
