Sun-Mar Centrex 1000 Low-Flush Central Composting Toilet System

The Sun-Mar Centrex systems offer all the benefits of a modern waste composting system while keeping the look and feel of a more traditional toilet in the bathroom.

The Centrex 1000 is designed for use with the following small footprint, low-flush toilets.

  • Model 510 Plus
  • Model AM Style II

Unlike self-contained composting toilets, this system is able to support as many toilets as you like. The limitation is how many people are using the toilets.

The Centrex 1000 model is best suited for seasonal or vacation use and is capable of supporting 3 adults full time or a family of 5 part time. Typically able to hold compost for a full season and only requires emptying in the spring!

For a ready to install system -  be sure to include one of the low flush toilets!
