Sun-Mar Composting Toilet Q&A

Sun-Mar composting toilets have set the standard for over 40 years, and our customers are the most important part of the story of Sun-Mar. In the last few years, we’ve heard from many who said that they would like more information about their composting toilet that isn’t in your owner’s manual.

After going over feedback, the idea of expanding our already extensive FAQ section was born. In the posts below, we will cover composting toilet topics our customers frequently ask. Our goal with these posts is to provide accurate, accessible and, most importantly, helpful information to both new and old Sun-Mar customers.

Below, you’ll find links to different posts we’ve written, such as winterizing your composting toilet or what kind of toilet paper is best to use.

If you have questions that we haven’t covered, no matter what they may be, we want to hear from you! There is no question too minor, and we might even have a post in the works. You can contact our marketing department via email and let us know. You can also reach out to us on our Facebook, Youtube, and Instagram

All Sun-Mar composting toilets have a 3 year warranty on parts. For information on Sun-Mar’s warranty, visit here.
