OGO Origin Composting Toilet

Our Verdict

The OGO Origin separates liquid and solid waste at the point of use — the key to odour-free composting. Urine drains to a front-mounted liquid bottle that is easy to remove and empty, while solids fall into the composting chamber where a built-in electric agitator mixes them with coconut coir or peat moss medium. The agitator runs on 12V power and can be activated manually or set to run automatically after each use. A small 12V ventilation fan draws air through the chamber and exhausts it outside via a vent hose, keeping the composting process aerobic and the bathroom odour-free. The OGO's lower profile and narrower width compared with some competitors makes it easier to fit in tight caravan bathrooms. The liquid bottle typically needs emptying every two to three days for two people; the solid chamber every four to eight weeks.
