The best urine-diverting composting toilet depends on where you’ll use it and whether you want a complete toilet or a separator component. The OGO Origin is best for compact van and boat installations; the Separett Villa suits waterless residential or remote use; and the TROBOLO WandaGO is designed for portable camping. The Thinktank offers a distinctive design, while the Frienda is a diverter for a toilet setup rather than a complete toilet.
| Product | Best For | Key Distinction |
|---|---|---|
| OGO Origin | Tight van, RV, or boat layouts | Compact footprint and 12V agitator |
| Separett Villa | Off-grid residential use | Waterless, high-capacity design |
| Thinktank Waterless Toilet | Buyers considering its specific user-oriented design | Airtight intake and exhaust pipes |
| Frienda Urine Diverter | Custom bucket or composting toilet builds | Separator component, not a full toilet |
| TROBOLO WandaGO | Camping and mobile use | Portable, adjustable-height design |
OGO Origin Compact Composting Toilet
The OGO Origin is best for van, RV, boat, and tiny-home owners who need a compact permanent toilet. Its listed footprint is 15 by 16 inches, and the design is intended for tight layouts where a side crank could take up room.
Urine collects in a 2.4-gallon bottle while solids remain in a rear bin. The 12V push-button agitator mixes solids without a manual crank. The manufacturer lists a solids capacity of 25–30 uses, making this a practical option for buyers who want powered mixing in a small installation.
Limitation: The agitator requires 12V power, and the listed solids capacity means users should plan for regular emptying based on use.
Separett Villa Urine-Separating Compost Toilet
The Separett Villa is best for buyers seeking a waterless toilet for a residence or remote location. Its urine-separating system is described as operating without additives or mixing, and the product is designed for use without water or plumbing connections.
Its high-capacity construction is intended to accommodate extended use between emptying cycles. That makes it a better fit for a stationary or longer-term setup than a buyer whose main priority is a lightweight portable toilet.
Limitation: The supplied product details do not give dimensions or a specific emptying interval, so confirm the installation space and maintenance requirements before choosing it.
Thinktank Waterless Toilet
The Thinktank Waterless Toilet is best for buyers who prioritize its user-oriented design and separate ventilation layout. Its listed features include a design intended to make use easier for women without aiming, and it is described as allowing men to stand.
The toilet has separate air intake and exhaust pipes and is described as airtight, a feature intended to limit the loss of heated or cooled indoor air. Choose this model if those design details match your household’s needs.
Limitation: The supplied details do not specify dimensions, capacity, power needs, or emptying frequency. Verify those points for your intended installation.
Frienda Urine Diverter For Custom Builds
The Frienda is best for DIY builders who already have, or plan to build, a composting toilet or bucket toilet. It is a urine-separating component, not a complete toilet. The semi-circular diverter is made from ABS plastic and measures 13.5 by 11.4 inches.
Its purpose is to direct liquid away from solid waste at the source, helping keep the collection area more organized. Consider it when assembling a custom dry-toilet setup and compare its measurements with the intended seat and collection arrangement.
Limitation: This product does not provide a complete toilet system. Buyers need a compatible build and should confirm the diverter’s fit before installation.
TROBOLO WandaGO Portable Composting Toilet
The TROBOLO WandaGO is best for campers and mobile users who want a portable toilet without water, chemicals, or electricity. It measures 12.3 inches high, 15 inches deep, and 13.4 inches wide, and weighs 10.4 pounds. The product is described as fitting in the storage compartments of many campervans.
The adjustable seat can be set to 12 or 17.2 inches. Its urine-and-solids separation and SafeShell System are designed to help limit odors and liquid spills. The listed supported load is up to 330.7 pounds.
Limitation: The product details do not state container capacity or an emptying schedule, so check whether its maintenance needs suit your trip length.
Buying Guide: How To Choose A Urine-Diverting Composting Toilet
Do you need a complete toilet or only a separator?
A complete unit such as the OGO, Separett, Thinktank, or TROBOLO includes the toilet itself. The Frienda is a component for a custom composting or bucket-toilet setup. Choose a diverter alone only if you can supply the rest of the system and confirm the fit.
Will it fit the installation space?
Measure floor area, seat clearance, and the route for any required ventilation or waste containers before buying. The OGO provides a 15-by-16-inch footprint, and the TROBOLO lists its overall dimensions. The supplied details do not provide measurements for every model.
Do you want powered or power-free operation?
The OGO uses a 12V motor for its agitator. The TROBOLO is described as operating without electricity, while the Separett is described as waterless and requiring no additives or mixing. Check the exact power and installation needs of any model before planning an off-grid system.
How important are capacity and portability?
For mobile use, compare dimensions and weight with available storage space. For longer stays, consider how often the waste containers may need attention. The OGO lists a 25–30-use solids capacity; the other supplied product details do not provide specific capacity figures.
