2. EcoJohn Basic Compost Toilet

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.

Pros:

  • Separates liquids and solids reducing smell and bugs.
  • Vents outside to further reduce smell.
  • Evaporates extra liquids from solids bin allowing longer use times between empties.
  • Looks more like a traditional toilet.
  • Removable bowl liner for easy cleaning.

    Cons:

    • Requires a vent installation
    • Requires 12vDC or 12vAC power for installation
    • Requires you to plumb a hose to a drain pit for liquid waste
    • Long shipping times, sometimes up to 6-8 weeks.
    • Requires a drain pit or storage tank for liquid waste.
    • Nothing stirs the solids bin so solid waste tends to pile up like a pyramid requiring more frequent empties.
    • Waste must be moved to a remote compost pile to fully break down.
    • Users will be handling raw waste. (Contained in a bag) so no direct contact.

      It works by storing liquid and solid waste in sealed bags after each use. After use, simply push the flush button and the bag you deposited your waste into is sealed, pulled into the bottom of the unit, and stored for later disposal.

      Its small size, low price, and sealed waste to avoid ever handling raw sewage has given it a real foothold in the tiny home, RV, and marine communities.
