Composting toilets are becoming increasingly popular as people become more concerned about climate conservation. A composting toilet is a great option if you want to reduce your carbon footprint. These toilets might not be right for everyone. While they have many benefits, there are also some drawbacks. Let’s take a look at the pros and cons of composting toilets to determine if they are right for you.

What is a composting toilet?

A composting toilet is a dry toilet, which does not require water to flush. The solid and liquid wastes go into a composting toilet separately and allow to dry out.

Commonly, carbon additives such as peat moss are added to each use. So, this helps to reduce the risk of unpleasant odors forming and aids in decomposition.

A composting toilet has a number of advantages. It does not need a connection to a sewer or septic tank, which is a major advantage. You will find composting toilets in many places, including national parks, remote holiday homes, ecotourism resorts, and homes that are off-grid.

Composting Toilets Pros And Cons



A composting toilet is a great option if you care about the environment. An ultra-low flow toilet uses 1.6 gallons of water per flush. Thus, making your family of four save approximately 11,000 gallons of water a year. A compost toilet is water-saving because it doesn’t use water.

Versatile and Space-Saver

Composting toilets don’t need water. This type of toilet does not require a water connection. They can be particularly useful in areas where traditional sewage systems are not available.


The composting toilets are natural fertilizers that you can use to feed plants and trees. They also eliminate the need for underground centralized sewage treatment facilities. On the other hand, regular toilets require a lot more water to flush. This is a combination with the need to treat human waste, and composting toilets may be an option.

Easy To Install

Composting toilets are much easier to install than traditional toilets. They don’t require the installation of plumbing or pipes, which means they are less expensive. A compost toilet is also self-contained and requires very little installation. A regular toilet, on the other hand, requires many steps before completing the installation process.


It can smell

Properly maintained composting toilets shouldn’t have any unpleasant odors. However, poor maintenance can cause odor problems. A composting toilet that effectively separates liquid from solids will decompose quickly and odor-free. If the liquids and solids are not separated sufficiently, this may result in a stench.

Your guests may not desire to use it

Visitors to your home should be aware that you have a composting bathroom. Most people won’t be too excited to use a composting toilet, as it will be something new. While some will be okay with it, others may prefer to have their traditional toilet at home. Not everyone will be eager to use a composting toilet.

Some composting toilets require electricity

To operate, some composting toilets require electricity. Some composting toilets come with an electronic system to speed up the process of decomposition. A ventilation fan can also be used to generate electricity. A compost toilet is popular for its water-saving and environmental benefits. These benefits may be offset by the cost of electricity, particularly the savings on water. There are also non-electric composting toilets, but the process of decomposition will take longer with these units.

May require local permits

Most urban apartments will not have the option of composting toilets. Composting toilets are not widely available in all areas, so it may be more difficult to find a suitable system.


There are many benefits to using a composting toilet. It’s great for the environment and also helps you save money on water. The composting toilet isn’t perfect, and there are some drawbacks. There are limitations on installation as well as potential odor problems, and sometimes the need to use electricity. These can negate the financial and environmental benefits of not using water.

In conclusion, composting toilets can be a very effective and environmentally-friendly way to manage household waste, but they also have some potential drawbacks.
