The CENTREX 3000 composting toilet is unique among the Sun-Mar’s Central units. It utilizes a continuous flow design for very heavy cottage or medium residential use. With a continuous flow system, rotation of the drum moves compost along the larger and longer CENTREX 3000 drum, before it drops automatically into the collection housing at the end of the unit. Under normal operating conditions, the drum will not have to be turned backwards for emptying.
All CENTREX 3000 electric composting toilets feature a built-in heating element and fan assembly. This unit is for use with a 1-pint, Ultra-low flush toilet, purchased separately. More than one toilet may be installed on this system, depending on needs and available space.
The Centrex 3000 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. Click to view the CENTREX 3000 on Sun-Mar’s webstore.

Bon service (Verified Home Depot Canada review)
This is the 2nd one I’ve owned
The first one lasted 22 years and I was still able to sell it to someone else. I’ve seen negative reviews about this product that I can tell you from experience are all attributed to operator errors. Read the directions and you’ll be fine. All compost toilets take maintenance. I use this in an airbnb and people are very impressed with it. No complaints. (Verified HomeDepot.com review)
10+ years and going strong!
I have an Excel NE, so I hope this is the correct model I’m reviewing. I own a small, off-grid island in northern Ontario. There was no possibility of having a regular toilet, due to the rocky surface necessitating an above-ground septic tank. (Not only the insightliness, but also the challenge of having an island septic tank serviced, made that option unsatisfactory.).
Happily, my SunMar composting toilet is an awesone substitute. We’re typically there every 2nd or 3rd weekend from May ‘til October, but have been there for a few weeks, at times, or had large groups for a few days. I even lived there for four months, in 2005. It handled it all very well.
The only criticisms I have are the ease of which the material forms into balls, which hold their shape even in the finisher; the large size; the price (although, with over a decade of use so far, the cost-per-use is low); as well as the handle’s tendency to to want to slide back into its groove, while turning. I am keenly aware of this latter fact, so I keep tension on the handle, pulling it towards me as I rotate it. But not everyone understands this, and I’m dreading the day I show-up and find a chunk of plastic snapped-off the handle or the unit. (I hate broken things.) Surely, a design adjustment could prevent this from happening, rather than relying on the user to remember to apply outward pressure while also turning. I think I’ve put an adequate amount if fear into everyone, which is why it hasn’t happened yet.
Do I recomnend this product? So much, yes! I keep wondering why this product isn’t mass-produced for countries where open pit elimination and outhouses are still commonplace? The user experience of this product is so similar to a standard toilet, it is probably the best choice for anyone wanting or needing to live greener. (Verified Home Hardware review)
