Nature's Head vs OGO Origin: 2026 Composting Toilet Comparison

Nature's Head vs OGO Origin: Which Composting Toilet Should You Choose?

The OGO Origin is one of the newest composting toilets on the market, and it's turned heads with its electric agitator and compact design. If you're comparing it to the Nature's Head Composting Toilet — the long-standing favorite in the van life and off-grid community — here's what you need to know.

Both are self-contained, urine-diverting composting toilets. Both run on 12V power. But they take different approaches to mixing, sizing, and manufacturing — and those differences matter depending on how you'll use the toilet.

The Electric Agitator: Game-Changer or Liability?

The OGO's headline feature is its electric agitator. Instead of turning a hand crank after each solid use, you press a button (or let it run automatically). The motor spins an internal mechanism that mixes composting medium with waste.

The upside: No cranking. This is genuinely appealing for people with mobility issues, arthritis, or anyone who finds the Nature's Head crank awkward to use in tight spaces. It's also more thorough in its mixing cycle.

The downside: An electric motor is a mechanical failure point that a hand crank isn't. Some OGO users have reported motor issues after 12-18 months of heavy use. If the motor dies, you can't easily fall back to manual agitation — the system is designed around the electric mechanism. With Nature's Head, a hand crank either works or it doesn't. There's nothing to burn out.

The OGO's motor also draws more power than Nature's Head's fan-only system. For van lifers on minimal solar setups, the difference between 1.68 Ah/day (Nature's Head) and 3+ Ah/day (OGO with agitator cycling) is worth considering.

Size: The OGO's Biggest Advantage

The OGO is meaningfully smaller than the Nature's Head:

• 4+ inches shorter in length
• 3.5 inches narrower
• Nearly 5 inches shorter in height

In a Sprinter van bathroom, a boat head, or a tiny home closet, those inches matter. The OGO fits in spaces where a Nature's Head simply won't without modification. If your installation space is severely constrained, the OGO may be your only option among full-featured composting toilets.

The trade-off: that compact size means less capacity. The OGO's solids bin handles roughly 25-35 uses for two people — about 2 weeks of full-time use. Nature's Head handles 60-80 uses — about 3-4 weeks. That's roughly twice the capacity between empties.

Urine Handling

Nature's Head uses a 2.2-gallon removable bottle. You pull it out, dump it, put it back. Simple.

The OGO gives you a choice: use the built-in 1.75-gallon tank, or plumb the urine directly to an external container or gray water system. The external drain option is a genuine advantage for permanent installations — you never need to handle a urine bottle at all.

However, the OGO's internal tank is smaller (1.75 vs 2.2 gallons), which means more frequent emptying if you don't plumb an external drain. Multiple reviewers note that the OGO's urine diverter can clog without regular maintenance.

Reliability and Track Record

This is where the Nature's Head pulls ahead significantly:

• Nature's Head has been on the market since approximately 2009. There are users with 10+ years of daily use on a single unit. The design is proven, parts are readily available, and the community of users is massive.
• OGO launched around 2021. It's a well-designed product, but it doesn't have the long-term reliability data that Nature's Head does. The electric agitator motor is the primary concern — it's the one component with no equivalent in older, proven designs.

Nature's Head carries a 5-year warranty. OGO carries a 2-year warranty. That 3-year gap speaks to the manufacturer's confidence in long-term durability.

Parts availability also favors Nature's Head — you can source replacements from Amazon, authorized dealers like Wild Oak Trail, and direct from the manufacturer. OGO parts come from a smaller company with potentially longer lead times.

Design and Aesthetics

The OGO has a more modern, streamlined look. Users frequently describe it as looking less like a "camp toilet" and more like a residential fixture. The smooth surfaces are easier to clean, with fewer crevices where dirt can accumulate.

Nature's Head has a more utilitarian appearance. It's functional and robust, but no one would call it sleek. The molded plastic seat isn't winning any comfort awards either — though the spider handle variant improves mixing ergonomics.

If aesthetics matter to you — especially in a tiny home or modern van build — the OGO has the edge here.

Who Should Choose Which?

Choose Nature's Head If:

• You want a proven design with 15+ years of real-world reliability
• A 5-year warranty matters (vs OGO's 2-year)
• You want more capacity (60-80 uses vs 25-35) and fewer empties
• Lower price is a factor ($1,035 vs ~$1,129)
• Made in USA is important to you
• You prefer no electronic failure points (hand crank vs electric motor)
• You want easy parts sourcing from multiple retailers

Choose OGO Origin If:

• You need the smallest possible footprint for a tight installation
• The electric agitator is important (mobility issues, arthritis, preference)
• You want to plumb urine to an external drain (built-in option)
• Modern aesthetics matter for your build
• You're comfortable with a newer product and shorter warranty

Frequently Asked Questions

Is the OGO better than Nature's Head?

"Better" depends on your priorities. The OGO is smaller and has an electric agitator — genuine advantages for some installations. Nature's Head has more capacity, a longer warranty, USA manufacturing, and 15 years of proven reliability. Neither is objectively better; they optimize for different things.

Can I use OGO accessories in a Nature's Head?

No. The systems are completely different designs with proprietary components. Coco coir composting medium is universal, but all hardware, bottles, and parts are brand-specific.

Which uses less power?

Nature's Head. The fan draws only 0.07A continuously (~1.68 Ah/day). The OGO draws more due to the electric agitator motor cycling in addition to the fan. For small solar setups, Nature's Head is the more power-efficient choice.

Which has better odor control?

Both are odor-free when properly maintained. The design principle is the same — urine separation prevents ammonia, and the 12V fan creates negative pressure to exhaust any trace odors. Neither has a meaningful advantage on smell.

Is the OGO Origin available on Amazon?

The OGO is primarily sold direct from the manufacturer and select retailers. Nature's Head is available on Amazon, direct, and through authorized retailers like Wild Oak Trail.

The Bottom Line

The OGO Origin is a well-designed, compact composting toilet with a clever electric agitator. If space is severely limited or you can't manage a hand crank, it's a strong option.

But Nature's Head has earned its reputation over 15+ years of proven, full-time use in every environment from Arizona ranches to Antarctic sailboats. The longer warranty, larger capacity, lower price, and USA manufacturing make it the more reliable long-term investment for most users.
