The Sun-Mar Mobile Compost Toilet is designed for boats and RVs. The mobile toilet is marinized to accommodate violent motion, with mounting brackets, a finishing drawer that is gasketed in, and a fold up footrest which can be easily removed to access the finishing drawer. With a width of only 19 1/2" and depth of 23" this medium-capacity, electric composting toilet occupies only slightly more floor space than a toilet seat.
Designed with a three-chamber system this composting toilet incorporates a patented Bio-drum which ensures a fast and odorless decomposition. The air intakes have to be located higher up and the air ducted down to the evaporating chamber. At the same time, a special drum locker ensured that the composting drum is held upright under all sea or road conditions. A 12 volt - 5.4 watt fan is designed to operate continuously while the unit is in use and also features a 115 volt base heater and thermostat that aids in evaporation.
This toilet has no pump outs, no changing containers, no pouring out urine, no chemicals. This self-contained toilet has little maintenance and works like a charm!
- Seasonal capacity: 3 adults or families of 4
