The Centrex 2000 and Centrex 2000 NE composting toilet systems are designed to handle larger capacity than the Centrex 1000 or the self-contained composting toilets. The Centrex 2000 and 2000 NE 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. To learn more about the 2000 and 2000 NE, read below!
“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.” – John D, Centrex 2000
*The WCM is a composting toilet model that is no longer produced by Sun-Mar. For comparison, the Centrex 1000 composting toilet is the closest available in terms of capacity.
“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.” – Bill M, Centrex 2000.
*Depending on where you are located, septic system installations can cost upwards of $10,000.
“We installed the Centrex 2000 last summer in our cottage in Minaki, ON. Over the years we tried propane and chemical toilets and neither worked. We are so pleased with the composting toilet. It is great.” – Russ and Heather B, Centrex 2000.
“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 absolutely no regrets! We have recommended the system & now there are several more installed on our island.” – M and G A., Centrex 2000.
“We are very happy with our composting toilet and feel very virtuous for helping to save the environment.”, Joan W, Centrex 2000.
“We were pleasantly surprised at the results the first time we emptied the drawer of our Centrex 2000. The compost was not offensive at all. The toilet is very easy to maintain. We use boiling water and your “Compost Quick” to clean it. We have a solar powered fan attached to it. We are very please with our investment, and feel that a composting toilet is the only way to go in a setting such as this. However, we also feel strongly that composting toilets should be introduced in “on the grid” settings as well, because they make good ecological sense.” – Sandra K, Centrex 2000 AF* NE.
*AF signifies the use of an Airflow dry toilet with the Centrex 2000 NE composting toilet. For more information, click here
“We are very pleased with our composting toilet at our seasonal lakefront cottage. We are happy to be “environmentally friendly”” – Roberta and Gary T, Centrex 2000.
“When greeting cottage visitors, most owners say something like, “Come see my new boat” or “Come see my new deck”. We say, “Come see the new outhouse!”. And it is truly lovely, all insulated and paneled in pine. It boasts a “Dutch” door to view the lake, a handy shelf for the coffee mug and a magazine rack for “Cottage Life” and “Canadian Geographic”. It truly does not smell. It is easy to keep clean and fresh. In summer, it is used daily to ease the pressure on the Centrex when there are lots of folks about. We are very concerned about the environment and endeavor to make minimum impact on our pristine lake and forest. Our choice of Sun-Mar installations is consistent with this goal.” – Jacquelyn M, Centrex 2000.
“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. The township inspector gave it the “thumbs up” as well.” – Pat and Mary M, Centrex 2000.
