    Product Description

    Sun-Mar Excel Self-Contained Composting Toilet

    The Excel is the best-selling unit in North America and for good reason. It is a high capacity Bio-drum toilet that is very simple to operate, features well proven technology and is extremely reliable. The Excel was the first ever self-contained composting toilet to be certified by the National Sanitation Foundation (NSF). So, when you purchase an Excel, you are literally purchasing a composting toilet that sets the standard.

    The Excel has enough capacity that it can be used just about anywhere: in residences, cottages and even in light commercial applications.

    To simulate residential use the Excel was tested by the NSF at maximum capacity for 6 continuous months, during which the Excel produced no odour and produced a clean, safe compost. Only Sun-Mar self-contained units are listed for residential and cottage use by NSF, whose Standard #41 is the toughest composting performance standard in the world.

    The 2" vent is attached at the top back of the Excel 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.

    In normal use the Excel can normally evaporate all liquids, however a ½" 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.

    How Composting Works

    Composting is Nature's Way

    Every living organism consumes nutrients and creates waste. To transform waste back to nutrients and complete this cycle, nature uses the processes of decompostition and evaporation.

    Sun-Mar toilets are designed not only to harness these natural processes, but to optimize and accelerate them.

    Toilet waste is over 90% water content. This can be evaporated and the small amount of remaining material is recycled into a useful fertilizing soil.

    Sun-Mar units are economical, quick to install and easy to use and because no chemicals nor septic systems are used, fragile environments can be protected.

    A Sun-Mar composting unit is an environmentally healthy choice for recycling human waste.

    And there's no smell!

    The Sun-Mar system evaporates excess liquid and by continuously pulling air in it ensures no smell escapes from the unit.


    By using a Sun-Mar composting toilet you are doing your environment a huge favor.

    1. You are protecting your lake and ground water from being polluted by pathogens and nutrients
    2. You are saving huge amounts of water
    3. You are recycling the nutrients directly back to the plants they came from.
