Sun-Mar Corporation-Composting Toilets

Customer service is not what I expected based on product reviews. I've tried repeatedly to find out about accessory availability. I've yet to receive a response.

We have had an Excel NE, non-electric for 5 or 6 years. We use it at our off the grid camp. Every year we have issues with flies. We have tried everything. DC fans, natural insecticides, vary the amount of moisture, removing the toilet from the camp and pressure washing it 1/2 way through the season. We have talked to Sun-Mar at the shows and visited their office a few times. They are always helpful. We can't stop the flies however and they are gross. If you buy a NE, I hope you have better luck. Maybe if you use it every day, it may work better. Ours is weekend use only. We will be biting the bullet and switching to a Cynderella propane incinerating toilet at 5 times the price of the Sun-Mar. 😦

Purchases a 3000 unit years ago for the cottage. Has served us well although the large size we selected and occasional/sporadic use meant it took years to finally get finished product. There were a couple hiccups which Sunmar addresses appropriately and we had to learn to monitor operation properly. I recommend the newer low water option if capacity for excess leachate capture is an issue. No solution is perfect so I rate this a 5 star. The system gave us a relatively cost effective option. We didn’t have to carve up a bunch of our mature forest property and got the cottage up and running faster as a result.

We bought a unit last year for our cottage and it worked very well. We have just purchased our second unit.

Our experience with Sun-Mar composting toilets dates back more than 20 years when we first installed one at our cottage. Since our experience was so great, my father and brother also installed them at their cottages and we have put one into the next cottage we bought. We especially love that we can use it during the winter when we snowmobile to the island. They make the BEST product and we hope to install one on our boat next.
