Composting Toilet Systems, Inc.

CTS has been a distributor of Sun-Mar products since 1992.

There are two different categories of Sun-Mar systems to choose from: Self Contained units or Central Composting Toilet Systems. All of our models, some 15 in number, fit into one of these two categories. Within each category we offer units for any power system; on-grid, off-grid, or no power at all.

Finding the toilet best suited to your need is as easy as selecting the right category and then answering a few simple questions.

SELF CONTAINED COMPOSTING TOILETS | Learn More >>

• Are waterless, and so require no plumbing for water connection or sewage. This means installation is very quick and easy.
• Are more suited to winter operation because it is often easier to keep the bathroom warm.
• Most (especially electric units) can evaporate all liquids, so approvals are not always required.
• Are available in different capacity units.

For Seasonal and Low Residential Use

• Are ideal for those who want a regular looking toilet in the bathroom, or who want to connect more than one toilet to the composting unit.
• Are normally placed under or outside the bathroom. Units can be up to 20 feet away.
• Are often unable to evaporate all flushing liquid (if any). This excess should be collected or drained to an approved facility.

For Residential and High Seasonal Use

• Environmentally friendly and a cost-efficient alternative to a septic system.
• Larger Bio-Drum composting chamber gives compost more residency time, ensuring a well-finished end product.
• For the first time in Sun-Mar's history, Sun-Mar quality is brought into the home with a unit suited to almost all residential uses!
