Compact Composting Toilet

Sun-Mar Compact In The Bathroom

Sun-Mar Compact, Installed 1996 at the primary residence of Julie Wyatt, in the US Pacific Northwest

Julie's email to Sun-Mar October 4, 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!"

Under The MacGregors' Cottage

Sun-Mar Centrex 2000, installed 2001 at the cottage of Bill MacGregor in Ontario

Bill writes:

We are thrilled with our Centrex 2000. As our cottage is built on rock, a septic system would have been very expensive. The Sun-Mar system is much more affordable and environmentally friendly, which is important to us.

Sun-Mar Compact installed 1999 in the cabin of Louise Perkins at Pocono Lake Preserve, PA

Louise writes:

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!

Sun-Mar Centrex 1000 installed 2003 in the summer cabin of E.M. Otto, near Thunder Bay, ON

Mr. Otto writes:

Our cabin is on a hillside (see photo), lots of rock and gravel. No place to put a septic system, even if we wanted one.

The 510 bowl has a straight drop to the Centrex 1000 in a insulated, heated containment unit under the floor. A flip up door allows for turning the crank without total loss of heat for winter use, very dry year, lots of drywells, doesn't worry us. The environment office suggested a compost unit when I called for a site inspection.
