The Sun-Mar Mobile was the first composting toilet specifically designed to recycle waste on boats and recreational vehicles. Less pump-outs! No more chemical toilets! Recycling brings freedom, with the ODOR-FREE operation of a Sun-Mar.

The Design of the Sun-Mar Mobile

Although the Sun-Mar Mobile uses Sun-Mar’s tried and true three-chamber system, “marinizing” the unit led to some interesting adaptations. The need to be able to handle violent motion meant that the finishing drawer had to be gasketed so that no liquid could escape from the evaporating chamber.
The air intakes face the same problem. These have to be located higher up and the air ducted down to the evaporating chamber.

At the same time, a special drum locker ensures that the composting drum is held upright under all sea or road conditions.
