Sun-Mar Composting Toilets
Sun-Mar designs and manufactures self-contained composting toilets. The company is based in Northern America and operates since 1971.
Sun-Mar is a pioneer engineer of composting toilets and holds a number of US patents for chamber designs. Sun-Mar developed the first self-contained composting toilet to pass the National Sanitation Foundation (NSF) long term composting tests which sets strict standards.
Sun-Mar composting toilets are compact units for homes with little or no underfloor space (e.g. concrete slab) and are available as electric and non-electric versions.
