The Sun-Mar Centrex system range is a split system, also known as an underfloor model. This means that the holding chamber is separate from the actual toilet pedestal itself. The major advantage of these systems is that they allow for greater holding capacity and therefore tend to be lower maintenance. If you have below-floor space for installation, then this is the range for you.

The CM8 Next-Gen is a split unit (below-floor) composting toilet system designed to be used by 5 people full time, and up to 10 people part-time. These systems are made from high-quality materials and are built to stand the test of time.

If you’re in a large household with extended family then it’s especially important that you choose a composting toilet that will meet the demands of your household. The CM14 has a capacity of 8-9 people for full-time use. That makes this system a great choice for large family homes, and also small public facilities.
