Head to Head Mini Guide: OGO Compost Toilet 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 Swedish brand, Separett, and their Villa 9215 model and seeing how it compares to a relative newcomer, the OGO Compost Toilet.

It can be hard to compare a 45 year old brand (Separett) with a "new on the scene" competitor (OGO), but these two share a number of functional similarities with a few key differences that set them apart.

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 and sold globally.
  • Both will work in many locations and applications: tiny homes, cabins, off-grid installs, rvs, workshops, basements, garages, and more.

OGO At A Glance

Launched in 2021, the OGO Compost Toilet is the most compact, fully self-contained composting toilet available today. The urine-diverting system keeps liquids and solids separate to eliminate smell and make emptying a snap.

Unlike other composting toilets, OGO ingeniously has a small 12V motor to start the compost agitation process. A simple button push is all it takes - no more hand cranking!

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 the OGO. Plus, Separett's biodegradable bags make emptying a breeze.

Biggest Pros

OGO: One Word - EASY!
No more hand cranking to start composting. After you go, the small, but powerful 12V internal motor handles the agitation process. It also is incredibly easy to empty and has a urine level indicator light so you know it's time.

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

OGO: Capacity
The OGO has a smaller solids bin than the Villa. It can hold about 30 uses before needing to be emptied. However, emptying OGO is an easy process and composting starts inside the bin.

Separett: Installation & Versatility
Installation is a little more challenging than OGO, 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 versatile as the OGO.

Which is the best? Just tell me!

WHY you should get the OGO Compost Toilet:

Get an OGO because you want a self-contained composting toilet with a super easy push-button flush, compact design to fit anywhere (with a normal sized seat!), clever venting to eliminate smells, wide-ranging applications, and a simple emptying process despite the slightly smaller holding capacity.

WHY you should get the Separett Villa 9215:

Get a Separett Villa because you want a urine-diverting toilet with large holding capacity, strong fan venting to prevent smell, very simple to use and empty, and you plan to use it in only one place (like your Tiny Home, Cabin, or RV).
