Important Factors to Consider
There are so many types and models of composting toilets or dry toilets on the market, that finding the best one for your needs could be quite difficult. If it seems too complicated to own a dry toilet, let us introduce you to this industry. There are many factors to consider when making a purchase as all models are equipped with different features and various functions. Of these, we will mention the most important ones:
Important Features |
Details |
Best Choice |
Capacity |
One of the most important things to consider when purchasing a dry toilet is the capacity. Actually, it represents how much compost fits into the special bag without overflowing. This strongly depends on how many people use the toilet and how frequently they use it in a given time frame. For example, if you are thinking about installing a toilet in your van, you can go for one with a small capacity as it won’t be visited by many people. If, however, you are thinking about purchasing a toilet for your home, for residential use, then, you might need one with a larger capacity. It will be used more frequently and you will be forced to empty its container more than twice a month. |
Sun-Mar Excel NE, Camco Standard 41541 |
Self-contained model |
Looking for a dry toilet? This is the right place to be. But, before making any purchase, make sure you know what kind of toilet you want. There are two different types of dry toilets available on the market such as self-contained and central units. The difference between these two models is that the first one composts the human waste within a tank that is usually connected to the toilet itself, while the other is connected to a larger tank in another location. As compared to the central units that are suitable for a considerable number of people, the self-contained one is a great choice for 2 or 3 people. Also, they are much more affordable and easier to install than the other ones. |
All models |
Ease of installation |
As mentioned above there are many things to consider when purchasing a dry toilet. Of these, it is also important to mention the installation process. As compared to other home appliances and devices that are extremely easy to install, installing this type of toilet is a horrendous task. If it is a self-contained model, it is much easier to install and you shouldn’t worry so much about leaks and splashes. You just have to seal them properly and anchor them in place. Also, pay attention to their ventilation pipe. For the best results and proper operation, it should be correctly installed. |
All models |
Size |
The size of a dry toilet is extremely important to consider when installing it. Unlike standard toilets, these systems are a bit bulky and in terms of design, most of them could have a chunky appearance. This will cheat your eyes and you will buy something that will not fit into tight spaces. The most advanced models come equipped with ventilation systems and additional tanks. Both are attached right to them, which might make it difficult to install into corners and tiny spaces. |

Maintenance |
You might think you have to clean a dry toilet regularly which is partially true. Although it doesn’t require a lot of maintenance, it still needs to be regularly emptied and cleaned. If you are using this kind of toilet, make sure you clean the bowl naturally, without chemicals and bleach. Instead, you can use vinegar and baking soda. More than that, if you are interested in electric toilets, pay attention to its connections as they can lead to a toilet malfunction. |

Debunking 4 Popular Myths About these Composting Systems
There are so many myths and fake news regarding these types of toilets that it is absolutely normal for people to have some misconceptions about such a system. If you are reading this, you might also have your own concerns and doubts about using this kind of toilet. In order to better understand how does it work and the whole idea of using it, allow us to introduce you to some of the most popular myths about dry toilets.
Dry toilet means bad smell and odors
You can control the bad smell of a dry toilet. Whether it is a standard toilet or a dry toilet, it won’t stink if you clean it. More than that, if it is properly installed and it works perfectly, you shouldn’t worry about bad smells. There are plenty of methods to control odors. All you have to do is to stick to them in order to avoid any trouble along the way.
Compost toilets are a sanitary nightmare
Stop thinking about these toilets as something nasty that will affect your health. These are just some toilets and if they are cleaned the right way, nothing’s going to happen. You won’t have sanitation problems if you empty and clean them according to your manufacturer’s specifications. Also, make sure you wash your hands properly after cleaning the toilet.
Avoid using normal toilet paper
This should be a joke! You can use any kind of paper you want. Since these toilets are made to decompose every waste that enters the composting system, there won’t be any clogging problems, especially because there are no pipes. Plus, thanks to this process the TP will disintegrate. Some people use dissolving liquids to speed up the TP decomposition.
There will be problems with the flies
What is the first thing you think about when you see a dry toilet? Odors and flies? Most people think the same thing about these systems, but this is a myth and the truth is behind the myth. Therefore, it is important to understand that if you regularly clean your toilet and you will use bulking agents, nothing’s going to happen and you won’t have this kind of problem. While some people use sawdust, others use mesh wire to keep the fly infestation away.
How Does a Composting Toilet Work?
Composting toilets are eco-friendly and great options for people who live in tiny houses, farms, boats or other small places. As compared to traditional septic systems, a composting system comes with a large capacity bin or two chambers for liquid and solid waste that needs to be cleaned regularly.
Theoretically, most of these systems are equipped with two chambers that keep the waste separated. Almost 90% of liquid waste will evaporate quickly. Om the other hand, the solid waste has to be removed manually when full. Typically, the solid waste is mixed with various elements, including sawdust, paper, wood chips, ash and some others that lead to the decomposition process. Also, it is recommended the use of some manual agitators to aerate the solid waste and maintain the right level of oxygen.
Also, some people use coffee grounds to promote a fast break down of solid waste. Once the chamber is full, it needs to be emptied and cleaned.
Now it comes the most complicated part. Not all people can understand that compost is used as a nutrient for garden soil. It doesn’t smell and it has the right properties of organic fertilizer. It is a great additive for flowers, plants, herbs and more.
