The Best Composting Toilets of 2024

A top-rated composting toilet, the Nature’s Head self-contained composting toilet is easy to install if you’re reasonably handy. This composting toilet has a large holding capacity when it comes to waste and can support a person weighing up to 300 pounds. The heavy duty construction includes a fan to disperse odor, though the manufacturer recommends keeping the toilet lid closed when not in use.

Even easier than installation is the use of the Nature’s Head composting toilet. Plus, its spider crank is easy to turn without any issues. Reviews mention the lack of odor as a selling point, describing this composting toilet as a “clear leader.”

The wall-mounted Separett Villa 9215 gets rave reviews from people who have tried other composting toilets in the past. This pick is a dry toilet, meaning there’s no liquid to contribute to gross smells, but there is a continuously running fan included in the unit to combat the possibility further.

Used in a variety of places—from campers to tiny homes—reviewers mention that this composting toilet is super easy to set up, even for first-time users, and that it’s comfortable to use as well. One reviewer’s favorite part of this composting toilet is the fact that you never actually have to see the inside of the solids bin and that there’s no need for compost medium and churning.

From individual use to families of ten, there are no real complaints, and this toilet can easily be used during high temperatures without any issues. We’d recommend the Separett Villa 9215 for people looking for a nice composting toilet option for places that don’t have sewer lines or septic fields. The only real downside from reviewers is that it is a costly piece, but in relation to other composting toilets of this quality, we think the price is quite comparable.

The very compact OGO composting toilet is a great pick for small spaces, even for daily use. With a built-in electric agitator, there’s no cranking or self-churning required, and disposal is just as easy. The liquids container is said to last for 25 to 30 uses before it needs to be emptied, and the useful indicator light lets you know when it’s time to empty the disposal unit.

This small composting toilet has the ability to accommodate two people daily for up to 50 uses. We would suggest the OGO composting toilet for small spaces or small families who are looking for something compact.

More of a camping toilet than a true composting toilet, the Stansport portable camp toilet is a great option for when you need to go on the go. A great addition to your camping arsenal, this toilet comes with a carrying bag for optimal portability. This toilet has a weight capacity of 250 pounds and includes sanitary bags, so you won’t need to worry about getting any additional supplies before making a trip to the bathroom.

While this toilet looks decently sized on the outside, the waste bucket is rather small and will need to be emptied after a few uses. For a low-cost portable option for bathroom breaks, this would be a good choice.

Whether you are in need of a composting toilet for your remote cabin, pool house on the lake, or anywhere else outside, then the Sun-Mar Excel Electric Waterless Composting Toilet is a solid choice. This toilet is ideal for anyone seeking to save on their use of water or who generally want to be sustainable.

With no sewer or water connection used during the composting process, this toilet is easy to use, simple to maintain, and leaves less of a carbon footprint. Reviewers also find that its ability to quickly decompose waste prevents odor. Even better: it is made of durable fiberglass to hold weight.
