Bob says his wife Bonnie and family are very pleased with their Compact which is "easy to use, very sanitary, no odors and very attractive". The cabin is used by three generations of Halvers and up to four people "on a weekly basis".

Although it is way above design capacity, Bob says the Compact "easily handled 8 people on weekends". For the sake of the Compact, we hope the fourth generation doesn't arrive just yet!

E-Mail from Julie, October 4th 2001:

"First, some background. The Main House has a conventional septic system with normal toilets operating therein, etc. However, when I added the art studio (where I now live), I had an opportunity to install the system of my choice: a composting toilet. It is an environmentally sound choice, and it "works" when we're out of power and/or water. (See below.) I might add that I did a lot of research before choosing your Sun-Mar.

I've used your composting toilet on a daily basis for the past five years. There have been cold, rainy, winter days when I've "hated" having to slog out into the woods to bury a wheelbarrow full of compost, but all in all, the toilet has served me well. It is serving me ESPECIALLY WELL at the moment, because our well, like so many others around here, has all but dried up. We're all praying for RAIN! One-third the normal rainfall this past year is not something we're used to dealing with in this (rainy) part of the Northwest! Anyway, I have an operating toilet while others are hauling in water to flush theirs. (grin) I might also add, that your product and your 'service' are absolutely TOPS; I've enjoyed every contact I've had with your company!"

We installed the Compact after struggling without success with another composting toilet for many years. The Compact is used daily for 4-6 weeks each summer and then for occasional weekend use the rest of the year. It works wonderfully!

This cabin has been in my family for 40 years. We have no running water, and for 37 years had an outhouse. The Sun-Mar Compact is the best investment we ever made - and at a fraction of the cost of a well and septic system. Using the bathroom at night no longer involves shoes, coat, and a flashlight!

We closed in part of the back porch to create a second bathroom and a laundry room. The Sun-Mar works well and avoided the necessity of installing a second septic system. The small stool makes it easier for the grandchildren to use the Sun-Mar, but we all use it.

We are very pleased with the Sun-Mar Compact electric. We have been using it for 2 years and I have had no problems. Sometimes as many as 20 people use it in one day and it holds up very well.

Due to County changes in the Code we had to install a composting unit. We have been very happy with the unit. We have only used Sun-Mar products as instructed.

Our cabin is only used for summer fun but the whole family enjoys it. We have had no odor problem which was a major concern when we decided to install the unit.
