    Product Description

    Sun-Mar Self-Contained Composting Toilet

    The Compact is an elegant low profile unit with the looks to complement any bathroom. Sun-Mar engineers designed this low profile toilet by developing and patenting a new variable diameter Bio-drum which is small at the front and large at the rear. To maintain the uninterrupted lines of the Compact, a patented Bio-drum handle recesses into the body of the unit to mix and aerate the compost.

    The Compact differs from the Excel in that all three chambers are smaller, which makes the Compact ideally suited to light residential or light to medium cottage use.

    As with the Excel, a 2" vent stack attaches to the rear of the Compact. A 1/2" emergency drain at the rear offers protection against heavy or residential use, or prolonged power outage.


    A composting toilet must perform three completely separate processes:

    • Compost the waste and toilet paper quickly and without odor
    • Ensure that the finished compost is safe and easy to handle
    • And separate, and/or evaporate the liquid contents

    Sun-Mar toilets fulfill these requirements with our patented Three-Chamber design*. These toilets consist of a Bio-drum™, a Finishing Drawer and an Evaporation Chamber.

    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.
