Sun-Mar composting toilets offer the consumer lots of choices in design, function, and personal preferences.  One of the first things you will want to decide is whether you want a self-contained composting toilet or a centralized toilet with the composting bin below the floor.

Self Contained

Benefits and uses of a self contained composting toilet include:

  • Operates without any water

  • Marine or RV uses

  • Quick and easy to install

  • Economical one piece design

  • Electrical models can usually evaporate all liquids

  • Electric and non-electric models available

  • Use where there is no space below floor level for a central unit.

Benefits and uses of a centralized composting toilet include:

  • Water free or 1 pint flush options

  • Traditional styled toilets

  • Options for multiple toilets

  • Electric and non-electric models

***A Sun-mar consumer, who is a wetland ecologist and restoration ecologist, suggests that you try to find some other source of bulking material than sphagnum moss. Sphagnum is an extremely slow-growing plant that forms only in specific wetland types (bogs) which take millennia to form. Just a hint to make you more environmentally aware so that we can, together, find an effective and environmentally friendly bulking organic material for these toilets.
