Sun-Mar Compact Composting Toilet

Sun-Mar Compact Composting Toilet

The Compact is an elegant low-profile unit designed to complement any bathroom. Sun-Mar engineers developed and patented a variable-diameter Bio-drum, which is small at the front and larger at the rear, to optimize composting. To maintain the unit’s sleek, uninterrupted lines, a patented Bio-drum handle recesses into the body to mix and aerate the compost efficiently.
