This one is newly installed after we finally retired our (Sun-Mar) Bowli X-L after 15 years of full-time residential use (family of 4). Needless to say, we were pleased with the product. Yeah, we had to “learn” the ropes of good composting, but I wonder how many times a plumber would be called to a flush toilet disaster in fifteen years! Had we had a dissatisfactory experience with the product, I can assure you, I would not have bought another!! We look forward to 15 more years of happy composting with our ecologically sound Excel toilet system.

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.

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 Prescott 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.

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

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”.

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.

“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.”

We cringed for years just at the thought of going/using the old outhouse at our family cabin site (see picture). 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.

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.

"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."

We installed a Sun-Mar Centrex 2000, with which we are delighted. (Caution - teach small children that this toilet is not like the ones in the city ---- our grandson flooded the unit by keeping his foot on the pedal waiting for it to fill up!) The Centrex is wonderful from Victoria Day weekend to perhaps Thanksgiving. But, since we are northeast of Parry Sound, plumbing cannot be used before ice-out or after freeze-up. So-o-o-o in May 2003, we built a beautiful little building to house the Sun-Mar Excel, a waterfree electric model, for use in April, May, October, and November.

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.

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.

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.

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.

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.

Sun-Mar EXCEL 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!

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!

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. Also enclosed are pictures of our Sun-Mar toilet. 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 our of our range in price. This sure made visiting our cottage a lot more comfortable.

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.

These are pictures of our (year round) home in Iowa and our toilet in its tiny room off our bedroom. I'm not sure how long we've had it - your records would probably tell - but its been 5 plus years and we are very happy with it. We had a cheaper "composter" before that turned out to be completely inadequate. Friends are often intrigued & surprised by it - especially that it doesn't smell bad.

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.

Just thought I would like to show you what a great product you have. Our cottage on Crowe Lake in Marmora Ontario sits on a rock cliff that makes it impossible to have anything other than a holding tank. We chose Sun-Mar because we loved the concept and it beats having an above ground tank by a mile. We selected another Canadian product from Royal Outdoor Products (Hampton garden shed) as our outhouse. We wanted to keep the cottage tradition of years ago by having an outdoor toilet. This is our third year and I find it to be a fantastic combination.

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.

We purchased a Sun-Mar Centrex 1000 for our island camp in eastern Maine which has been happily established and composting since then. That model we installed in a small outbuilding, and is pictured in the two photos. 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.

Our Excel-NE is an excellent addition to our primitive Colorado mountain cabin. It is odor free and simple to install. The ladies and grand kids appreciate it, especially during the winter. They don't have to make the 75 yard trip to the outdoor toilet.

I have a Sun-Mar Excel-NE that I installed about 6 years ago and is still working perfectly. It is situated in the public bathhouse of my windsurfing B& B in Baja California, Mexico.

Everyone loves to try my toilet. They are sure its going to smell - and it doesn't! It is easy to use and easy to care for. Thank you for making this product available.
