There are two different categories of Sun-Mar systems to choose from, Self-Contained units and Central Composting Toilet Systems. All of our models, 22 in number, fit into one or the other category. 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 needs is as easy as selecting the right category and then answering a few simple questions. Select the category below that best suits your needs. Do you want a flush toilet? Do you want to avoid putting in plumbing? Do you need a unit for four or more residential users? Choose your category based on these general preferences. Click on the section that you are interested in going to to open up that sections front page.

Are waterless, and so require no connection for water or sewage. This makes installation very quick and easy!

Are more suited to winter operation because it is often easier to keep the bathroom warm. Capacity is up to 6 adults seasonally, 3 adults residentially (Excel model).
