Benefits of Using Composting Toilets

  • On average a regular toilet consumes 3.16 gallons per a single flush. In short, where some countries do not have water to drink using this much water to flush seems morally wrong. But with a composting toilet, you do not have to feel guilty anymore. This toilet does not use water to flush out the excrement. This means you save at least 3.16-gallon water every time you use the toilet.
  • Have you ever thought about how to turn waste into something useful? Many people do not think about it. But in reality, just like animal excrement, human excrement can be used for compost. You do not have to do anything manually. The toilet will take care of that. And by the end of the week, you would have useful compost ready to use.
  • The regular toilet units are difficult to install. The process needs to hire a professional. Because without their help the seat would start leaking or flush will not work. But the composting toilet is each to install. Most of the units come with an instruction manual that makes the process even easier. Which is why anyone can install this toilet with the hello of a few tools.
  • This type of toilets is best for areas where there is no water available. For instance, campsite, cabins, and even RVs. This the rain why many owners of “house on wheels” prefer composting toilets.
  • It is a common fact that vegetables and fruits are good for health. But most like the flesh is nutritious so are the peels. With a composting toilet, you can not finally use the peels for a good reason. Just dump the kitchen waste in the composting bin.

2. Weight:

A lighter weight of 100 lbs composting toilet is best suitable for upstairs cabins and campsite. Most of the smaller-capacity models are usually lightweight.

3. Self Contained or Central Unit:

The composting toilet comes in 2 different types. You can either come to a self-contained toilet or a central unit. So, what is the difference between both of these? Well, a self-contained toilet is the one that composting that waste in the built-in tank. Meanwhile, a central unit store the waste in a different tank at a different location.

4. Electrical or Non-Electrical:

Many composting toilets used electricity to create a better environment for fertilizer. Whether the electric toilet is best for you or non-electric, it depends on the location. If the place you want to install the toilet has electricity then get an electric toilet. Otherwise, a non-electric toilet works great too.

5. Capacity:

The capacity needed is determined by how much the unit will be used. Which means it depends on users’ personal needs. For instance, if someone is getting a toilet for home then the bigger capacity is better. But for a hunting cabin or beach but, a smaller capacity will work too.

6. Installation Process:

Regular toilets are usually difficult to install because you have to deal with it. Otherwise, the tile will start leaking and ruin the bathroom. Unlike that, a composting toilet is easier to install. Just make sure you get the unit that comes with proper instructions and does not need any fancy tools.

7. Safety:

Here safety means your health. Many poorly made compete toilets do not compost the waste effectively. And become a habitat for bacteria and pathogens. Which is why you should get the best toilet possible to avoid infections.

8. Price Range & Warranty:

Well, just like any other product, composting toilets are available at different prices. The larger one with a bigger capacity is usually expensive. So, get the toilet that suits you.
