Head to Head Mini Guide: Nature's Head vs. Separett Villa 9215

Welcome to ShopTinyHouses' Head-to-Head Mini Guide series where we pit two respected toilet brands against one another and compare their pros and cons to help you make a better decision.

Today, we're looking at the well-known Nature's Head Composting Toilet and it's long-standing Swedish competitor, the Separett Villa 9215.

One of the biggest similarities between them is product longevity and brand success. Separett has been developing waterless toilet systems for over 45 years and Nature's Head has been around for over 15.

It's hard to choose between two acclaimed models like this, but our goal is to help you decide which one will meet your specific needs.

Both toilets are ready in the ring (bowl?), so ding that bell and let's get to it.

The Similarities:

  • Both toilets are completely waterless.
  • Both are "urine-diverting" toilets.
  • Both manufacturers are well-respected in the industry.
  • Both will work in many locations and applications: tiny homes, cabins, off-grid installs, rvs, workshops, basements, garages, and more.

Nature's Head At A Glance

The Nature's Head is a true self-contained composting toilet. Launched back in 2007, this waterless system eliminates the need for plumbing via a clever urine-diverting process to keep liquids and solids separate - which ensures you have no smell from the composting process.

It has a user-friendly design and is made of high-quality materials, including stainless steel hardware, ensuring it will be durable enough to last for years.

Villa 9215 At A Glance

The Villa 9215 is Separett's most recent composting toilet with significant tech upgrades. The urine-diverting system keeps liquids and solids separate to eliminate smell and make emptying a snap.

The urine separation process uses an external drain rather than storing liquids inside the toilet. This gives it a larger solids holding capacity than Nature's Head. Plus, Separett's biodegradable bags make emptying a breeze with no need to hand crank.

Biggest Pros

Nature's Head: Best-in-Class Composting
The industry leader for high quality urine-diverting, fully self-contained toilets. The installation process is simple and the toilet has no smell, plus lower utility costs (since it's waterless). It's larger solids bin allows for more visits prior to emptying.

Separett: Capacity & Ease of Use
No hand cranking needed as the bin isn't used for long-term composting. The urine-diversion process increases solid holding capacity (4-6 weeks depending on toilet paper use). It also is incredibly easy to empty and uses biodegradable bags.

Biggest Cons

Nature's Head: Emptying the Solids Bin
It's a part of life with a composting toilet. Emptying the Nature's Head requires you to unhook the bowl unit from the bin to remove and empty. Not a big hassle and only takes a few minutes, but is more work than the Separett.

Separett: Installation & Versatility
Installation is a little more challenging than Nature's Head, but comes with all parts necessary. Because it uses an external drain line, Separett works best in tiny homes, cabins, rvs, and off grid settings, but is not as mobile as Nature's Head.

Which is the best? Just tell me!

WHY you should get the Nature's Head Composting Toilet:
