Sun-Mar’s 110V Compact composting toilet allows you to enjoy the convenience of an indoor bathroom in any location, with standard 120V electricity! Perfect for on-grid vacation cabins, small homes, guest cottages, or even an off-grid cabin or home, with the use of a generator.

In a weekend or vacation cabin, the Compact can be used by 3 adults or a family of 4. For regular full-time use, SunMar recommends a limit of 1 adults or a family of 2. From the manufacturer:

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.
