  • Composting,Waterless,Urine diverting, off-grid, toilet

There are several portable composting toilets available on the Internet. However, after checking here and there, we concluded that our choice for the best portable composting toilet is the Separett Villa 9215 AC/DC toilet. Its design is pleasing to look at, it is durable, and it does its work excellently.

What is a portable composting toilet?

A portable composting toilet is a kind of toilet that speeds up the process of decomposition by regulating aerobic conditions within the composter. It is alternatively referred to as a portable biological toilet or a dry toilet. It is a system that acts as waterless sewage treatment, requiring little to no plumbing for waste disposal. They can shed off a significant volume of waste and are great for outdoor camping, recreational vehicles, etc.

What are the different types of portable composting toilets?

Portable composting toilets come in different shapes and forms. These forms are designed in such a way that they meet different needs. This includes the topography of the area it is to be used on, among others. Regardless of the different forms and shapes, there are only five major kinds of portable composting toilets. This classification is based entirely on how they function. Here they are:

 Dry/Waterless composting toilet

With a portable composting camping toilet, sometimes, you get a flush system. Sometimes, you do not. Regardless of what system yours has, a portable composting toilet generally uses very little water to flush. A dry/waterless model uses no water at all in carrying out its functions. They are an excellent choice for camping. Additionally, they hardly cause any odor. As such, your options broaden, and you can include them in your recreational vehicles for that reason. 

Self-Composting toilet

This toilet comes with its own composting system that’s often located beneath the bowl itself. It carries out all its functions by itself from taking the waste in the initial stage to composting the waste. This is another type of toilet that you can use for camping. It is, to put simply, self-sufficient. That quality helps take out any unwanted stress.

Central composting toilet

This kind of toilet does not come with its own composter. Instead, it is connected to a central system that does the work for it. So, when you need to ease yourself, your waste is taken somewhere else where it is taken care of. For an area that generally has several composting toilets, this model is great. However, practically speaking, it might not be the best idea if you are looking for something you can set up and use on the go.

Electric composting toilet

Having been around for as long as it has, it is only natural that electricity would become a part of every aspect of our lives, however intimate. The electronic version of a composting toilet has a fan. Its job is to make sure that air circulation does not stop within the composting site. This is necessary because composting cannot happen if the right aerobic conditions are not met.

These electric toilets can be connected to a wall outlet. However, this is not very useful for those looking to use the bathroom outdoors. Thankfully, there are alternatives. There are portable composting toilets that are battery and solar-powered. Generally, electric composting toilets are some of the most efficient at carrying out their functions.

Non-electric composting toilets

A direct contrast to the aforementioned, this type uses electricity alternatives like wind turbines. Some of them come with a crank that you have to operate manually. The whole thing is just to allow for proper waste mixing. In all honesty, it can be a bit of a hassle. Not a lot of people want to kneel next to their poop and then spend a couple of minutes twisting and turning to “mix shit up.” However, it just might be an excellent choice for you if you are the type of person who loves green and environmentally friendly products.

What are the top five portable composting toilets you can use?

Occasionally, you’ll want to buy something online, probably on amazon or Ebay. it’s clearly more convenient when you order stuff from your couch instead of going to physical stores and spending several hours of your day moving from one aisle to another in search of your item. Consequentially, you type in a simple search query. The next thing you know, your screen is flooded with advertisements of people claiming to be the best. All of these can be a bit overwhelming. As such, we have taken a careful look around and compiled a list of the best portable composting toilets that you can get for yourself without any regrets. Without further ado, they are:

It comes with an elongated seat. This might be great for you if you are a guy who is looking for just a bit of extra room to do your business. Apart from that, the elongated seat guarantees all of the comforts that come with a traditional toilet’s elongated seat. Additionally, it does not take too much effort to disassemble. No need to spend several minutes hunched over a steaming pile of human excreta trying to get the toilet open. This toilet’s functional design allows for a quick disassembly that happens in a matter of seconds. 

The product is the brainchild of two sailors who sought to create something with much better user experience. Due to the nature of their jobs as seamen, they designed the toilet to withstand the harshness of terrain in a ship. However, today, that rugged design works in your favor. The toilet can be used anywhere from a camping site to a recreational vehicle and everything else in between.

Buying Guide

What should you look out for before buying the best portable composting toilet?

If you are going to invest your money in a product, it should be able to serve you properly. If that must happen, it has to meet a few requirements peculiar to its line of work. For your sake, we will briefly mention a few features your portable toilet must have if you are to buy it. 

  1. It must be durable. 
  2. The waste capacity should be as large as you need it to be. If there are up to five people using the toilet, you might want to get one that has larger waste containment facilities. That way, you don’t have to dispose of it ever so often.
  3. It should be easy to move around and should not occupy too much space. The latter is especially crucial if you will be using it indoors, like in RVs.
  4. It should be energy efficient.
  5. It should be able to decompose waste at satisfactory speeds.

Frequently Asked Questions (FAQs)

Q1: Can I use a portable composting toilet during freezing temperatures?

It largely depends on the kind of toilet you buy. As we stated earlier, composting occurs in these toilets by regulating aerobic conditions. Some toilets primarily work under warm temperatures. However, some are built for less than friendly weather and can be used in freezing temperatures. These types sort of find a way to keep themselves warm during the cold of winter. It all depends on the kind you choose to invest your money in.

Q2: Does it smell?

A reasonable cause of worry for a portable composting toilet owner is that it might smell. However, the way these products are designed does not exactly allow for them to smell. This is so because they are not open systems. As such, they don’t allow for the ventilation of the byproducts of the broken down materials into the atmosphere. This type of toilet produces less smell than traditional toilets. However, you must dispose of the compost material before it gets too full. Refusal to do so will result in a disturbance of airflow within the system. This can cause the creation of offensive smells.

Q3: How often should you empty a portable composting toilet?

The frequency depends largely on the number of people using it as well as the duration. If two people are using the toilet full-time, depending on its size, we estimate that you can empty it every two to three weeks. If just one person is using it full-time, the disposal interval increases based on the frequency of toilet visits. when there are more than two people, the disposal time reduces as well. There is not exactly a straight mathematical rule that calculates how long you should wait before throwing out your waste. However, as a general rule of thumb, you should not wait too long before disposing of it.

In conclusion

Having a portable composting toilet comes with several advantages. The fact that it helps you save water is one big plus. However, choosing one for yourself might be a bit of a problem. In this guide, we have helped you to reduce the burden of making the decision alone by providing you with our list of the best portable composting toilets. Now, all you have to do is make your order.
