The Excel is not only our best-selling unit, but also the first self-contained composting toilet to be certified by NSF (National Sanitation Foundation) in 1989. Since then, we have made many modifications to improve performance in all three chambers - evaporation, composting, and finishing. When you purchase an Excel, you are purchasing the composting toilet that sets the standard.

Sun-Mar is a world leader in composting toilet technology.

  • Sun-Mar toilets are sold by a global network of thousands of dealers

Why use a Sun-Mar composting toilet?

  • no water
  • odor-free
  • inexpensive solution

Environmental Benefits:

  • no pollution
  • saves water
  • recycles nutrients
  • little or no liquid output
Sun-Mar's self-contained toilets are quickly and easily installed anywhere a toilet is desired. All toilets are manufactured to the highest standards using advanced materials. The durable smooth contoured finish makes these toilets attractive and easy to clean. All units feature Sun-Mar's patented Bio-drum™ and unique three chamber technology that provides ideal composting conditions. All self-contained toilets are waterless, require no plumbing and provide odor-free operation. Sun-Mar toilets compost all regular toilet paper. 

The Excel is ideal for residential use having been tested by NSF with 4 adults using the unit residentially for six months of continual use. In this test, the criteria were that the unit operated odorlessly and produced clean, safe compost. Of course, it did, and the Excel is presently the ONLY self-contained unit in the world to be tested, certified, and listed by NSF.

The Excel is also ideal for cottage use as the primary toilet at your camp or cabin, or for light commercial or workplace use. The 2" vent is attached at the top back of the unit and can be installed invisibly by running it through the wall and up the outside wall. For comfort the Excel has a sturdy detachable footrest which can be removed to pull out the finishing drawer.

Although the Excel can normally evaporate all liquids, a 1/2" emergency drain is fitted at the rear and this should be connected if the unit is to be used residentially or heavily, or if prolonged power outages are expected.
