About Sun-Mar

For several decades Sun-Mar has been the leading producer of waterless composting toilets in North America. Ecoflo has been distributing Sun-Mar toilets in Australia and the Pacific since 2004.

The unique technology developed by Sun-Mar ™ is to use a patented horizontally mounted rotating drum to accelerate composting. The efficiency of any compost pile is enhanced by turning it, resulting in a more homogenous and better aerated mix. Whilst the Sun-Mar ™ technology is superior in many respects, it requires relatively large composters. For this reason Ecoflo mainly stocks the split system toilet, the Centrex, with its composter under the bathroom floor. The split system Excel models can be specially ordered. Please contact us for details if required.

The Centrex is also unique because it is the only Australian and NZ Standards certified micro flush composting toilet system. This is the toilet for people who do not believe a visit to the toilet is complete without wasting water (aka flushing). The micro flush ceramic pedestal typically uses only 1-2 litres of water per day per family. The efficiency of the Sun-Mar composter is such that the solids are converted to humus as effectively as a 100% waterless toilet.

A recent introduction to the Sun-Mar ™ range is the GTG, designed for mobile situations such as RVs and boats. The conventional looking but minimal floor space pedestal separates the urine and collects waste for composting elsewhere. For details of this and other Sun-Mar ™.products visit www.sun-mar.com.au

Ecoflo Wastewater Management has been distributing Sun-Mar™ waterless and micro-flush toilets in Australia for over 15 years. The toilets are Australian & New Zealand Standards certified with various State and Territory approvals. 

In the spirit of reconciliation, Ecoflo Wastewater Management acknowledges the Traditional Custodians of this Country. We pay our respects to their Elders past and present and extend that respect to all Aboriginal and Torres Strait Islander peoples today. 




Ecoflo was the first company in Australia to sell composting toilets certified to the rigorous quality testing of Australian Standards. If you want to be certain your composting toilet has adequate capacity and is safe, you need a waterless composting toilet certified to the tough performance criteria of AS/NZS 1546.2:2008.
