How Does It Work?

Composting toilets work in an easy and straightforward manner. One makes use of natural evaporation and decomposition process to recycle and turn human waste into compost that can be added to the soil, which can take advantage of nutrients for better nourishment.

The waste that enters the toilet is more than 90% water. It will be evaporated and taken back to the air through its vent. Then, the solid waste materials, which are now dehydrated, are converted into compost or fertilizer for the soil.

Again, it is done through a natural evaporation or decomposition process. It is one of the reasons that this toilet system is chosen by people that want to save the environment because it doesn’t leave an impact to the environment. It uses a natural process that can control the surroundings in the composting chamber.

The composting toilet can ensure a total waste decomposition and an odor-free operation because it can balance the elements, including organic materials, moisture, heat and oxygen to ensure a good aerobic bacteria environment in order to transform human waste into a fertilizing soil.

This toilet system can decompose human waste properly, so the end products it produces don’t contain viruses and pathogens, which are destroyed by the bacterial breakdown.

The fertilizer produced can be added to the soil or be placed around the base of trees or on the plants. It conserves local water quality and reduces commercial fertilizer use.

Overall, the composting toilet works in a straightforward manner without any hassle. It can preserve the environment and local water quality and supply. The composting toilet also reduces commercial fertilizer requirements as well as electricity and water consumption. If you’re looking to reap these benefits and more, you might want to consider getting a compositing toilet for your boat, cabin, truck, mobile home, bus, recreational vehicle, off-grid home or anywhere electricity or water is unavailable.


How to Choose the Best Composting Toilets

Now, we’re down to the things to consider when finding the best toilet for off-grid living, camping, recreational vehicle living or marine applications. Let’s discuss them and later be able to compare what you have to weigh when choosing the right composting toilet for your needs and situation.

Central or self-contained units

Simply put, the self-contained toilet is one that connects to itself while the central unit connects to a larger tank in another location. If you’re looking for ease of use, you should go for the self-contained unit. It is ideal for smaller locations and groups.

On the other hand, you might want a central unit if you belong to a larger group because it can hold and process a larger amount of waste at a time. However, you might want a self-contained toilet if you have no additional tank or you don’t want that kind of setup.

Care and maintenance

Standard toilets don’t require much maintenance but keeping the bowl clean all the time can be the pretty basic cleaning you can do for it. On the other hand, you need to do more than that with a composting toilet.

For one, you have to remove the compost regularly to ensure it’s working properly. Or else, it will overflow and cause a mess. More so, you have to inspect the connection if your toilet is running on electricity; otherwise, the toilet will malfunction.

Installation ease

A composting toilet needs proper sealing, or leaks will be an annoyance and trouble. You might want to go for a self-contained unit, which proves to be easier to install than a central unit is. The self-contained unit can just be anchored in place with its ventilation pipe installed, too. It is one of the reasons that this toilet system is better when it comes to installation ease.


How much waste can it hold without overflowing? That refers to its capacity, which must depend on how often you’re using the toilet and how many people are using it.

You might want a smaller toilet if you’re using it for a hunting or camping cabin that you don’t frequent often and if a smaller number of people are going to use it. However, a larger capacity toilet should be chosen if more are using it in an area of residence.


If you intend to use the toilet anywhere, you might want to go for a lighter one, even if they’re quite more expensive than other heavier models are. However, take note that a heavy unit can be much harder to bring in a space upstairs in a camp or cabin.



Finding the right toilet is no easy task. There are so many of them from different brands and with unique features. But it can be if you know what to look for, including installation ease, weight, type of composting toilet, capacity and care and maintenance.

You should also consider other features you deem important based on your situation and needs (large group, small space and other things).

To get started, you might want to begin comparing and weighing your options based on the above list of the top composting toilets out on the market now. They’re from trusted brands and well reviewed by customers worldwide. Get your best composting toilet today!
