Choosing the Correct Tiny House Toilet System

Tiny houses are a popular housing trend that is here to stay. With their small footprint and minimalist design, tiny houses offer a unique living experience that is both practical and efficient. However, one area that many tiny house dwellers struggle with is finding the right toilet for their small space. In this article, we will explore the various toilet options that are available for tiny houses, including composting toilets, portable toilets, traditional toilets, and incinerating toilets. We will discuss the pros and cons of each option and help you determine which toilet is the best fit for your tiny house. Whether you are looking to go off-grid or simply want a toilet that fits your small space, this article will provide you with the information you need to make an informed decision.


Composting Toilets

Composting toilets use microorganisms to break down solid waste and turn it into compost. When using a composting toilet, solid waste is deposited into a holding tank where it is mixed with dry materials such as sawdust, wood chips, or peat moss. These dry materials help to absorb moisture and create an environment that is conducive to the growth of microorganisms. As the microorganisms break down the waste, the temperature of the composting material rises, which helps to kill any harmful pathogens.


After the waste has been fully composted, it can be safely removed from the composting toilet and used as a soil amendment in a garden or other outdoor space. Composting toilets do not require a connection to a septic system or sewage treatment plant, making them a good option for tiny houses on wheels or other off-grid living situations. They are also more environmentally friendly than traditional toilets, as they do not produce sewage that must be treated before being released into the environment.


Macerating Toilet

A macerating toilet is a type of toilet that uses a grinding process to break down solid waste and flush it through a small-diameter pipe. These toilets are commonly used in situations where the distance between the toilet and the main sewer line or septic tank is too great for a traditional toilet to be used.


The way a macerating toilet works is as follows: When the toilet is flushed, water from the tank is released into the bowl, which helps to move the waste into the grinding chamber. Inside the grinding chamber, a spinning blade or impeller grinds the waste into small pieces. The ground-up waste is then mixed with water and pumped out of the toilet through a small-diameter pipe, typically made of PVC.


The small size of the pipe and the grinding action of the toilet make it possible to install a macerating toilet in areas where a traditional toilet would not be feasible. However, these toilets do require electricity to operate and can be noisy, so they may not be the best choice for every situation.


Portable Toilet aka Portapotty

A portable toilet is a self-contained unit that is designed for temporary use and can be easily moved from one location to another. Portable toilets are commonly used at construction sites, outdoor events, and other locations where a permanent bathroom facility is not available.


Inside a portable toilet, there is a small holding tank that is used to store waste. When the toilet is flushed, water is released from the tank and into the bowl, which helps to move the waste into the holding tank. The holding tank is designed to be sealed and odor-free, so that the portable toilet can be used without creating an unpleasant smell.


After the holding tank is full, it must be emptied and cleaned by a professional waste management company. The frequency with which the tank must be emptied will depend on the size of the tank and the amount of use the toilet receives. Portable toilets are a convenient option for temporary or outdoor use, but they may not be the best choice for long-term or permanent use.


Incinerating Toilet

An incinerating toilet is a type of toilet that uses electricity to burn waste, reducing it to ash. These toilets do not produce any sewage and do not require a connection to a septic system or sewer line, making them a good option for tiny houses or other off-grid living situations.


When using an incinerating toilet, solid waste is deposited into a holding tank. When the tank is full, or when the user activates the incineration cycle, the waste is burned using an electric heating element. The burning process reduces the waste to ash, which can be safely disposed of in a trash bin.


Incinerating toilets do not produce any sewage and do not generate odors, making them a hygienic and convenient option for small living spaces. However, they do require electricity to operate and may not be the most environmentally friendly option, as they do produce some carbon dioxide emissions during the incineration process.


Traditional Toilet

A traditional toilet is a plumbing fixture that is used for the disposal of human waste. It consists of a bowl, a tank, and a flushing mechanism. When the toilet is flushed, water is released from the tank and into the bowl, which helps to move waste from the bowl into the plumbing system.


The bowl of a traditional toilet is designed to trap waste and prevent it from emanating unpleasant odors. When the toilet is flushed, the water in the bowl is released through a series of small holes, called "jet holes," which helps to clean the bowl and wash the waste away.


The flushing mechanism of a traditional toilet is typically a handle or a button that is located on the side of the tank. When the handle or button is pressed, it releases a valve that allows water to flow from the tank into the bowl. This process creates a suction effect that helps to flush the waste from the bowl and into the plumbing system.


Traditional toilets are connected to a plumbing system that carries the waste away from the toilet and into a septic system or sewage treatment plant, where it is processed and treated before being released into the environment.


Outhouse

An outhouse is a type of toilet that is typically found in rural or outdoor areas where a plumbing system is not available. It is a simple structure that consists of a small enclosed room with a seat and a hole in the ground. Waste is deposited through the hole and into a pit or tank that is located below the seat.


The main advantage of an outhouse is that it does not require a plumbing system or a connection to a septic system or sewage treatment plant. This makes it an economical and practical option for areas where these facilities are not available.


However, outhouses do have some limitations. They can be unsanitary if they are not properly maintained, and they can produce unpleasant odors if the pit or tank is not emptied regularly. In addition, outhouses can be inconvenient to use in cold or inclement weather. For these reasons, outhouses are not as common as they once were and are generally only used in very rural or remote areas.



In conclusion, finding the right toilet for your tiny house can be a challenging task. There are a variety of options to consider, including composting toilets, portable toilets, traditional toilets, and incinerating toilets. Each type of toilet has its own unique benefits and drawbacks, and the best choice for your tiny house will depend on your specific needs and preferences. When choosing a toilet for your tiny house, it is important to consider factors such as your budget, your lifestyle, and your environmental goals. By weighing these factors carefully, you can choose a toilet that will meet your needs and provide you with a comfortable and convenient living experience.
