QUESTIONS & ANSWERSAsk a Question
Can I use toilet paper with this compact composting unit?
Yes you can use regular toilet paper with this composting toilet.
Can you tell me if there is a warranty on the Sunmar composting toilet?
There is a warranty on the Sun-Mar composting toilet. It is three years on any part that fails and five years on the fiberglass tank, provided that our inspection shows that such failure is due to defective
material or workmanship.
the sunmar composting toilet that i ordered was not the right choice for my needs. unfortunately i had to find this information out by opening the carton and reading the manual. although perfectly suited for personal use, i had chosen it for a guest studio in my barn. the necessary maintenance required more intimacy with effluence than i would want for my guests. returning it will cost me both shipping and a 20% restocking fee. none of this is the fault of tiny houses.
We just added this composting toilet to the bathroom in our tiny house on our horse ranch. It really is odorless and works very well. It was the easiest part of the remodel!
I've owned my Compact for a few years now and have learned how to maintain it without much effort at all. It was a little bit of a pita at first. The bathroom never has any odor due to the fan. I did install the factory supplied rheostat to reduce fan speed and it helped to reduce noise but it is still apparent. Urine has been a non-issue for us. I did pipe the overflow hose to a small eco-sump outside, located in a small plastic tank (filled with sand and other materials according to internet specs). My Compact is in a barn not in our house to avoid installing a second septic tank. For my house I would install the type that has remote composting tank, but this is much larger than the Compact. The Compact is a nice looking toilet. It is a little higher than standard toilets. We have had no issues with hardware, defects, or any kind of failures. I would recommend this unit as long as you are committed to learning how to use it according to instructions and are not too put off by doo-doo,
