Sun-Mar is the world leader in composting toilets, and dominates the North American market with its unparalleled range of 23 models from 6 different product families. Each model is distinguished by innovative design, superior technology, and Sun-Mar's legendary quality. Each carries an amazing 25 year warranty on the body.

Working like the compost heap in the backyard, but odorlessly and much faster, Sun-Mar toilets break down human waste and toilet paper through the natural process of decomposition. Because most of this waste is evaporated, only a very limited quantity of finished compost is produced. Oxygen, moisture, heat, and organic material are needed to allow minute natural organisms into transform the waste to fertilizing soil.

There are two different categories of Sun-Mar systems to choose from, Self-Contained Units and Central Composting Toilet Systems.
