“We have enjoyed the unit from day one. It is cost efficient and is the answer to our dilemma (solid bedrock ground and land slopes to the lake; impossible for septic and lagoon). Your product took us from an outside privy to indoor leisure and comfort and besides, we are saving the environment.” – Greg W.

“We purchased a Sun-Mar Centrex 1000 for our island camp in eastern Maine which has been happily established and composting since then. … Since we were so pleased with that one, and feeling we needed to provide additional toilet facilities for larger groups visiting, we have installed this summer a new Sun-Mar Excel. This self-contained unit has gone into another small cabin adjoining a kitchen and bedroom.” – Deborah B.

“We purchased one of your Sun-Mar composting toilets in July of this year, the Excel model, electric. This is just a few words to let you know that my husband, Ron and I are very pleased with the unit.
It is situated on 8.5 acres of land in a wooded area. … Everyone who has seen it are amazed by it, to say the least. My husband and I are retired and this was a great purchase, as the cost of installing a septic field was out of our range in price. This sure made visiting our cottage a lot more comfortable.” – Ron and Claudette

“We have been very satisfied with our composting toilet. Rather than having to pay for a septic system we are able to use the compost to fertilize our garden and boy do the flowers grow. Thank you. Sun-Mar is definitely the way to go.” – Tom O.

“People are always surprised when they enter what they expect to be an ordinary outhouse and find a clean toilet with “no odor!”. And also to learn how easy it is to manage. We have found the new Compost Sure to work much better.” – John P.

“It may be THE invention of the 20th Century. It is so great not to have to worry about a septic system, sewage smells, etc. We think the composting toilet is excellent.” – Tom H.

“Our Sun-Mar EXCEL is installed in our cabin on Lake Buteau. We have been very happy with this product being installed in our cabin in the bathroom. Excellent performance and we have had as many as 8 people for several days at a time. No problems. When eventually I do put a permanent septic in this will go in the second bathroom for usage when people are on the lake and don’t want to go back to the cabin. The best thing is that I didn’t have to have a Septic permit to install it!” – Steve and Karen B.

“We built our cabin in 1965 – we are in the country so we have no public utilities except electricity and telephone. With the Excel installed I am able to spend 2 or 3 months here during the summer. It’s great! Thanks!” – Donna M.

“We installed the Sun-Mar Excel (electric unit) when we built our grey-water greenhouse system. The year round solar greenhouse handles all our grey water and the Sun-Mar makes it possible. The combination is permitted by our county health dept. as an experimental system and in Year 4, going on 5 we still love it.” – Cindy H.

“We are on the Chesapeake Bay. No water or sewage available. Have had your unit for about 3 years and find it a great reward. My wife likes the waterfront property, but never did get fond of an outhouse.” – Ed. L

“We installed our Sun-Mar Excel during our summer holidays in July 2001. Friends and family are amazed at how well it works. It has become a conversational piece.” – Steve R.

“Being on the Minas Basin, with the world’s highest tides (yes! the earth actually tilts at high tide) we have to cope with coastal erosion. Old septic systems can be a problem because of leaching into the seawater. Sun-Mar toilets are a great environmental choice and great too for cold-weather visits to our cottage. My ornamental shrubs enjoy a spring perk-up when we spread our clean compost in May.” – Patricia W.

“We cringed for years just at the thought of going/using the old outhouse at our family cabin site. Then we were introduced, by a neighboring cabin owner, to the Sun-Mar composter toilet. After using the Excel composter, we consider it the most practical investment we could have made. The most surprising element – total lack of any offensive odors.” – Lynn L.

“We installed our Excel Electric in the Spring. At our cabin we have greywater disposal, but not sewer. We have a lot of guests on weekends, so we try to all use the “indoor” toilet (the composting toilet) on rainy days, or at night… and we use our outhouse when we are outside anyway. I found the job of emptying the toilet this Spring not bad at all, the dirt looked like top soil, no evidence of toilet paper or anything. We are very happy with the product.” – Lorrie B.

“We have now had 4 seasons to learn to use and manage the Sun-Mar Excel and it is working well. There is really not much compost to remove in the Spring. We find that using both the Microbe Mix and the Compost Quick when turning the drum is the best formula, along with the regular addition of the peat moss/sawdust mixture (Sun-Mar addition – 50% peat moss, 50% wood shavings or Compost Sure peat mix is ideal mixture). There is no odor to speak of, the fan is quiet, and you don’t have the regular noise of waste water being flushed.” – Frank and Anna M.

“Very pleased with Sun-Mar Excel. We use it 3 months during the summer and haven’t had any problems.” – Gilbert M.

“Since the cabin is without plumbing, the Excel was and is ideal. It looks good and everyone can use it without a problem. It has serviced a large group (12) on a given day and is odorless. We are so glad we found this system, otherwise we would not have purchased our “get-a-way”.” – Barbara C.

“Its been great. No mess, no fuss, its saved on overuse of our septic system. I’d recommend it to anyone. We built a solid step for further comfort.” – Ruth C.

“Thanks to the Sun-Mar Excel unit I was able to obtain a sewage permit and begin construction on our cabin in the Alleghany National Forest. The Excel model was approved as an alternative to a septic system. We have used the Excel model for four years and are very satisfied with its performance.” – Jim C.

“We’ve been using the outhouse for over 60 years at our cabin in the Adirondack mountains of Northern NY & still do not have running water. We really appreciate the Sun-Mar Excel, especially on cold early Spring mornings and late fall mornings. Installation on the second floor was easy with no expense for septic system or water system. Has worked well with 10-12 people in the cabin for 2 week stays in the summer.” – Everett G.

“Our cottage is near a river and so a septic was not an option. Additionally, we have tried to be as environmentally friendly as possible in our building, Tyvek house wrap, sealed vinyl windows, a front load low water washer and compact fluorescent bulbs in all the fixtures, even outside lights. We would love to be part of your Web Site. I tell everyone about how great this toilet is. I even told our local Rotary Club about how great these toilets are. Our model is an Excel 120v model. It runs all summer and all winter in the cottage. It’s great to have an door plumbing. We have followed the instructions completely and use Compost Sure, Microbe Mix and Compost Quick. We have never had a smell or a problem.” – The Williams
