Hello there, fellow homesteaders and enthusiasts. Ever thought about how much water you could save by swapping out your traditional toilet for a composting one? A couple of years ago, I did, and I’ve never looked back. Let’s dive into this exciting, water-saving, eco-friendly world of composting toilets together!
What is a Composting Toilet?
A composting toilet is an innovative toilet system that operates without a septic tank, transforming human waste into compost. It’s an excellent alternative to the standard toilet we’re used to, especially if you’re living off-grid, in a tiny home, or just aiming for a more sustainable lifestyle.

Composting Toilets vs. Traditional Toilets: What’s the Difference?
Unlike a regular toilet, a composting toilet doesn’t flush waste away. Instead, it captures and breaks down solid waste in a composting chamber using natural processes. Unlike flush toilets, which require a significant water supply and a sewage system, composting toilets handle waste in a way that reduces water usage to almost zero.
When I moved into my first house, the water supply was a big challenge. The idea of flushing gallons of clean water away every day with a standard toilet just didn’t sit right with me. That’s when I started exploring other options.
How Does a Composting Toilet Work?
A composting toilet works by using aerobic bacteria, present in organic matter, to decompose human waste into compost. It’s a self-contained system where your waste, together with other organic material like peat moss or wood chips, undergoes the composting process.
Dry toilets, like composting toilets, separate liquid waste from solid waste, which is critical for the process. Too much water can drown the living organisms that help with the decomposition. Most systems also include a ventilation system to aid in the composting process and prevent bad smells.
Setting Up Your Composting Toilet
Creating your own composting toilet might sound daunting, but it’s actually pretty straightforward. To set up a self-contained compost toilet, you’ll need the toilet seat and a separate container or two for waste. An absorbent material, such as peat moss, coconut coir, or wood shavings, is also crucial to help control moisture content and excess liquid.
Remember, composting toilets can be as simple as a bucket with a toilet seat or as sophisticated as Sun-Mar toilets with their separate containers and fans to aid in composting. Depending on your living situation, you’ll find different types to suit your needs.

Maintaining Your Composting Toilet
To ensure your composting toilet works effectively, regular maintenance is essential. This involves adding bulking agents like wood chips to balance the carbon-rich material in the compost pile and turning the compost heap periodically to keep the process active.
My first composting toilet was a simple single-unit model. Keeping a stash of peat moss handy was a lifesaver to control excess moisture. Also, emptying the toilet wasn’t as bad as it sounds! Just ensure you have a compostable bag or a sturdy plastic bag handy, and you’re all set.
The Results: Using Compost in Your Homestead
The end product of a composting toilet is compost material that’s rich in nutrients. This can be used in your garden compost for flowers, providing valuable organic matter that promotes plant growth. I can personally vouch for the flowers that flourished in my compost-enriched flower garden!
However, remember that compost from a composting toilet should generally be used on non-edible plants due to potential health hazards. I generally use it for my flower beds, while food waste goes into the compost bin for my veggie patch.
Composting toilets are a fantastic alternative to traditional toilets, particularly for those in tiny homes or rural areas. They’re environmentally friendly, reducing water consumption significantly and offering a viable solution for waste disposal.
As someone who’s been there, setting up your own composting toilet can seem a bit intimidating, but it’s absolutely doable. Remember, composting is a slow process, and a well-maintained composting toilet should not emit any bad smells.
Making the switch to a composting toilet has been one of the best decisions I’ve made in my journey towards a more sustainable lifestyle. It’s been a great choice for my house and an eye-opening experience into how we can use natural processes to live more in harmony with our environment.
So, are you ready to make the switch and say goodbye to flushing gallons of water down the drain? I can’t wait to hear about your journey!

FAQs
1. Where do you empty composting toilets?
Emptying a composting toilet varies depending on the model. For self-contained composting toilets, the compost can be removed directly from the unit. For central system composting toilets, the compost is typically removed from a composting chamber located outside the house. After removal, compost should be further composted in a compost pile or bin to ensure it is fully decomposed and safe to use.
2. Do you ever have to empty a composting toilet?
Yes, you do need to empty a composting toilet. The frequency of emptying depends on the size of the composting chamber and the number of people using the toilet. For a self-contained compost toilet in a tiny house with one or two people, it might need emptying every few weeks to a couple of months. A larger central compost toilet system for a family could go up to a year or more before needing to be emptied.
3. What if you have diarrhea in a composting toilet?
Composting toilets can handle diarrhea, but it might make the composting process a bit trickier. Diarrhea can increase the moisture content in the composting chamber, which might require adding extra bulking agents, like wood shavings or peat moss, to help absorb the excess liquid and maintain a good composting environment.
4. What are the drawbacks of a composting toilet?
While composting toilets have many benefits, there are a few potential drawbacks to consider. They require regular maintenance and emptying, which some people might find off-putting. Also, if not managed properly, composting toilets can produce bad odors. Some models may require electricity for fans or heaters, which could be an issue in off-grid situations. Lastly, in some areas, local regulations may pose challenges to installing and using a composting toilet. However, for many homesteaders, the environmental benefits and water savings outweigh these potential drawbacks.
