QUESTIONS & ANSWERSAsk a Question
Does it need a water source? Does it need ventilation?
No water source is needed for this toilet but it will need to be vented to the outside.
The actual toilet is great but the heater and fan didn't work. Waiting for replacement from Sun Mar in Canada. Disappointing to spend $2,000 and it not be complete.
Awesome people to deal with. Kept me informed every step of the wa
Great, this is our 3rd Sunmar composting toilet, Tiny Houses and Sunmar are great!
I have owned this for over 6 years and can't believe how easy it is to use, clean and maintain. I highly recommend the exhaust muffler to reduce the exhaust sound. I have never had odors and for some reason bugs, spiders and insects are not attracted to it. I have it in a shed at our camp site and everyone loves it! I had a problem with the fan shortly after I bought it and Sun-Mar replaced it for free without any hassle. It has never given me any other troubles since in 6 years. My wife is thinking of running a business in a room over the garage and I will install one of these as a bathroom for her clients. My acupuncturist had one in his office :-) Great company, Great product! Worth every penny!
Haven't used the item yet, but the buying process was great.
