Sun-Mar Centrex 2000 NE (Non-Electric) High Capacity Central Composting Toilet System

The Centrex 2000 NE (Non-Electric) Central Composting Toilet System is a step up from the centrex 1000 NE in every way. It provides longer composting cycles, larger waste storage volume, and the ability to use as a wet or dry system! The Centrex 2000 NE is designed for medium to heavy seasonal or light residential use.


 Sun-Mar Centrex 2000 NE Dimensions

  • Height & Depth: 26.5" x 26.5"
  • Width & Crank Clearance: 45.5" x 49"
  • Weight: 87lbs
  • Depth required for Drawer Removal: 45"

When used seasonally by up to 6 adults, compost will normally only need removing annually each spring. In residential use compost will have to be extracted more frequently.

When used full time by up to 3 adults, some compost will need to be emptied into the finishing drawer once every few months.

Centrex central composting systems offer all the benefits of modern waste composting systems while keeping the look and feel of a more traditional bathroom.
