Sun-Mar Spacesaver Electric Medium Capacity Composting Toilet Please call for shipping


Choose Color: White

The success of the Excel design meant that a three chamber unit could be specifically designed for those with NO continuous 110 volt supply. First launched in 1981, the Excel NE has long been the standard toilet for those living off the grid. A 1998 redesign gave the unit a rounded look, and recessed the drum handle.

The SPACESAVER is a standard three chamber unit designed specifically for situations where space is extremely limited. With a width of only 19" and depth of 22", even a closet or small corner can now be turned into a bathroom!

The SPACESAVER is fitted with the same kind of high quality turbo-fan as other electric units have. The difference is that on the Space Saver, a 3" vent stack is included.

The SPACESAVER has almost the same size Bio-drum as the COMPACT, so composting capacity is similar to that of the Compact. On the other hand, evaporation is limited by the smaller heater and evaporating surface, so the safety drains should be connected.

Listed capacities refer to the amount of people, on average, using the unit per day. Do not pick a unit that is below your capacity.
