OGO Origin Composting Toilet – Compact Electric Agitator
Brand: OGO
Ideal for space-constrained vans needing effortless, odor-free composting.
The OGO Origin is a game-changer for van builders who think they have no room for a composting toilet. Its 15×16-inch footprint fits into corners and tight spaces where other units simply won’t go, making it ideal for Sprinter and Transit vans, tiny homes, and boats. Despite its small size, it doesn’t compromise on functionality—the push-button electric agitator means you never have to crank a handle, keeping the process effortless and mess-free.
Urine diversion is built-in, with liquids separating into a 2.4-gallon bottle while solids stay dry in the rear bin, lasting 25–30 uses before emptying. This separation eliminates the black tank smell entirely, making storage safer and more pleasant. Made in the USA from durable polypropylene, the OGO also features quiet fan ventilation to keep odors at bay, ensuring your off-grid adventures remain fresh and comfortable.

Buyer’s Guide: What to Consider
Choosing the right RV composting toilet involves balancing space, capacity, and convenience. Keep these key factors in mind to find a model that fits your lifestyle and vehicle.
- Size and Footprint: Measure your available space carefully. Compact models like the OGO Origin fit in tight corners, while larger units like Nature's Head require more floor area. Consider the height and depth, especially in vans with low ceilings or narrow aisles.
- Urine Diversion: Urine-diverting toilets separate liquids from solids, reducing odor and making compost management easier. This is a key feature for most RV composting toilets, as it keeps the solids bin dry and prevents the growth of odor-causing bacteria.
- Agitation Method: Some toilets use a manual handle to mix solids, while others offer electric agitators for effortless operation. Electric models, like the OGO, are more convenient but require 12V power. Manual models are simpler and more reliable but need a bit more effort.
- Capacity and Emptying Frequency: Consider how often you want to empty the solids bin. Larger capacities, such as Nature's Head's 4-6 week interval for two people, are great for full-time use, but they also mean a bulkier unit. Smaller bins are lighter but require more frequent maintenance.
- Ventilation and Odor Control: A good ventilation system is crucial for odor control. Look for models with built-in fans and carbon filters that actively remove smells. Some toilets also feature airtight designs to prevent odors from escaping, which is especially important in small, enclosed spaces.
Conclusion
Selecting the best RV composting toilet comes down to your specific needs: space constraints, frequency of use, and desired convenience. For tight van builds, the OGO Origin’s compact size and electric agitator are unbeatable. Full-time RVers will appreciate the high capacity and reliability of Nature’s Head models, while campers might prefer the portability of the TROBOLO WandaGO.
No matter which you choose, switching to a composting toilet eliminates black tank hassles and brings you closer to sustainable, off-grid living. Consider your priorities, and you’ll find the perfect match for your adventures.
