EcoJohn Basic Tiny House Composting Toilet

The EcoJohn Basic is a step ahead of the Lovable Loo in a few ways. It looks more like a modern toilet, so your visitors won’t be quite so shy about using it. And more importantly, it separates the liquid waste from the solids.

Separating the liquids from the solids helps cut down on odor as well as increasing the capacity of the toilet. This separation also helps the waste break down and compost more quickly once removed from the unit.

The EcoJohn Basic also has a 12vDC (120vAC Optional) fan that runs to help exhaust the odors outside. This ensures no smell stays in the home. It also has a heating plate in the bottom of the toilet to help dry out the solid waste.

  • Vents outside to further reduce smell.
  • Evaporates extra liquids from solids bin allowing longer use times between empties.

    • Requires a vent installation
    • Requires 12vDC or 12vAC power for installation
