Top Picks of Best Composting Toilet 2018 Reviews

 

1. Nature’s Head – urine separating composting toiletsurine separating composting toilets

This self contained portable type of toilet is one of the easiest and most economical ones to use. It is made of stainless hardware and has a specially structured seat to make sitting down easier. It also has a design that makes it easy to disassemble when needed. It also includes a durable vent hose and extraction fan for evaporating liquids.

What many customers like about this product is that it doesn’t need to run using water or electricity. It is the best product for those who camp outdoors very often but don’t want to do business in the woods. It is very easy to install, so you won’t have to worry about calling an expert to assemble it for you. Best of all, it is odorless, just as it is supposed to be.

However, when compared to most brands in the market, this one is pretty expensive. Thus, if you want to enjoy the features of this product, you have to be ready to pay a rather big amount.

 

2. Nature’s Head – best composting toilet for tiny housebest composting toilet for tiny house

When it comes to composting, this product is probably one of the most efficient options to choose. This is a self-contained composting toilet that is powered by electricity and comes with a 12-volt power plug. It also comes with a hand crank agitator to aid in the composting process.

One of the best and most unique things about this product is its crank handle. By using the crank handle found at the base, you can accelerate the composting process. This makes it easier for you to get rid of the waste and use it for your garden or for fuel in your house. Overall, it is one of the most user-friendly composting toilets you could ever have.

However, just like all Nature Head brands, expect to pay a hefty sum for all the features. Like the one mentioned before this, this product is also quite expensive. Another con is that it is quite high, so it might be hard for shorter people to use it. Those who are below 5’4 might have a hard time getting up to the toilet to do their business.

 

3. Sun-Mar Corp – best composting toilet for cabinbest composting toilet for cabin

This Sun-Mar product is another self-contained electric composting toilet that is great for people staying in a cabin. It is small-sized and includes a venting kit that makes it a super flush toilet as well. It also has a capacity to take a max of 3 to 4 full-time users in the area. Furthermore, it also includes a detachable footrest for more comfort.

One of the best things about this model is that it is compact and small. It’s very easy to install and very easy to bring around because of its size. It also doesn’t have a lot of power requirements, so it can be installed in pretty much any household. Just like all self-contained composting type toilets, it doesn’t need water for it to work. It also has a drawer in the base that stores the feces, so it’s easier for you to dump.

While it does a good job of storing the feces, the same can’t be said for urine. It has the tendency to leak the urine out if it’s already full. This means that you may have to dump the urine more than 2 times in one month.

 

4. Sun-Mar – non electric composting toiletnon electric composting toilet

Another compact toilet from Sun Mar. This particular product is a self-contained type of a composting toilet that doesn’t need electricity to run and doesn’t need water. This one is bigger than the one mentioned above and has a capacity to accommodate 5-7 people in a household. It also comes with a venting kit and an emergency drain.

The great thing about this non-electric composting toilet is that it can still be used even during a blackout or drought season. It doesn’t need electricity or water to run, which makes it very practical and flexible. It also includes a variable diameter bio-drum that makes the composting process easier for you.

This one also has the same problem with the urine storage. It often leaks when full, so you might have to dump the urine more than once a month.

 

5. Villa 9210 – waterless composting toiletswaterless composting toilets

The Villa 9210 DC/AC is an electric self-contained composting toilet that can be hooked to either a battery source, an electric source, or a solar source with its AC adaptor. It also includes a built-in fan that allows it to have an air flow mechanism for easier flushing. This product was also made to be able to easily catch and store urine in a special tank so that it won’t leak. A separate tank holds the feces and toilet paper, making the disposal of waste much easier.

This is probably one of the most efficiently made composting toilets. When it comes to storage, this is one of the best you’ll find. It has a smart urine-diverting mechanism and an efficient fecal storage facility. This will help you to have an easier time with the composting process. It will also help you to dump the waste better. Because of the storage facility, you don’t need to dump the waste more than once in a month.

While it’s got a really good storage system, it doesn’t have such a big capacity. This means that it can only take around 2-3 full-time users, which is the standard for most composting toilets anyway.

Buying Guide to Best Composting Toilets

 

Now that you know how a composting toilet works, the types there are to choose from, and what benefits they give, we can go on to the complete buying guide. When looking for the best composting toilet for your home or for traveling, there are a few factors that you have to take into consideration. Here are the factors:

Ease of Installation

First of all, you have to take into consideration the ease of installation of the composting toilet you want to buy. Self-contained composting toilets are the easier ones to install since they just run on electricity. Centralized system toilets need a bit more plumbing since you need to install the composter underground with a pipe.

Type of Composting Toilet

We’ve mentioned the types of composting toilets in this article. All you have to do is choose the one that works best for you. An electric or self-contained one is good for those who live in cabins or in homes where there’s electricity. Central systems are good for those who like to go camping and traveling a lot.

Number of Users Allowed

Obviously, the more users allowed, the better the toilet. However, most portable composting toilets only allow up to 2 full-time and 3 part-time users. When we say full-time users, they are those who use the toilet every day. Part-time users don’t use it every day. You can use this figure as your benchmark when you look for a good composting toilet.

How Often It Needs to Be Emptied

We usually look at how long the toilet can last before it needs to be emptied. For a standard usage, you usually need to empty the toilet once a month or more times, depending on how often it is used. However, if you can find a toilet that can last for more than a month, then that one will be a better option.

Including Composter

One of the most important things that you have to look at would be whether or not there is a composter attached to the toilet. In most centralized systems, there is a composter below the toilet that is attached via a pipe. There are also toilets that don’t have composters attached to them. For these, you might need to manually dump the waste into an external composter. You will choose which one you’d like to have.

Consumables Needed

Finally, you must also look at whether there are consumables needed or not. Generally, composting toilets need Coco Coir or Peat moss that is dumped into the base of the toilet so that you can decompose the waste. So when you go to the store and buy your composite toilet, always ask the one assisting you what consumables are needed when you use the toilet so that you’ll know how to use it.

 

Benefits of A Composting Toilet

 

If you’ve never used a composting toilet before, you might be wondering how come a lot of people like buying composting toilets. Simply put, a composting toilet has a lot of benefits that outweigh buying a regular toilet. Here are some of the visible benefits of the best composting toilets:

Easy to Install

A composting toilet is extremely easy to install. With most traditional toilets, you need to hook up a lot of pipes through a piping system and a water system. A composting toilet doesn’t need all of that. You just need to hook up the unit to a composter at the bottom of the toilet. Other than that, it’s pretty much self-contained. Some are even portable, which means that you can bring them around wherever you go.

Not Too Expensive

Another benefit of buying a composting toilet is that you don’t need to spend so much to buy one. While a traditional toilet is pretty expensive because you also have to pay for the plumbing and the installation, a composting toilet doesn’t incur all those added costs. Just pay for the unit and you can start using it right away.

No Odor

One of the biggest reasons why people buy composting toilets is because they’re odorless. With a traditional toilet, it’s still possible to smell traces of urine or feces that have gone down the toilet right after you flushed. Fortunately, a composting toilet doesn’t have any of that, so you won’t have to suffer from any bad smell.

Good for the Environment

Since a composting toilet doesn’t use water to operate, it’s really good for the environment. That’s because you won’t be wasting so much water when you do your business because you don’t need to flush. It’s also perfect for those who reside in a place where there is a scarcity of water.

Good for your Garden

Finally, a composting toilet is great for your garden. If you’re manning a garden, you can use the compost heap from your composting toilet as fertilizer. With this, you no longer have to buy manure or fertilizer from the store because you can pretty much make yours. Other than your garden, you can also use the compost as extra fuel for your home. It is combustible and can be used in stoves or ovens.

 

How Does a Composting Toilet Work?

 

 

If you’re not that familiar with composting toilets, you probably don’t know what to look for in these appliances. Before we go to the buying guide, it’s important that you understand some things about composting toilets.

Unlike regular toilets, composting toilets make use of a natural decomposition process that recycles human waste. When the waste enters the toilet, the water evaporates it by the use of a vent system. Any remains are then used as fertilizer for the soil.

When you dispose of the waste, you’ll be disposing of urine and feces separately. For urine, most composting toilets these days come with extraction fans and an evaporation system. This means that you don’t need to dump so much urine on the ground manually.

Dumping the feces can be a little bit more challenging since they smell worse, and they’re solid. So before you tackle the solids, we recommend that you put on a pair of gloves and you also wear a mask. Once you’re ready, start by removing the liquid tank. Then, take out the vent hose and the power cord, and take the whole toilet to your dumping ground. Get a trash bag and put it over the top of the base. Put some hydrated coco Coir on the base and let the composting process take place.

Once that’s out the way, you can place everything back together and use the waste of your fertilizer.

 

Types of Composting Toilets

 

Generally, there are three types of composting toilets that we’ll go through. These are the self-contained composting toilets, the one-pint flush composting toilets, and the waterless composting toilets. Let’s take a look at them one by one:

Self-Contained Composting Toilets

The first type is the self-contained composting toilet. This one isn’t portable, but it is, nonetheless, a composting toilet. It can easily be installed in your bathroom. However, it requires an electric system to be powered. The great thing about these units is that they are waterless, so they don’t require plumbing and any installation to a water system.

One-Pint Flush Composting Toilets

Another kind of composting toilet is the one-pint flush composting toilet. It’s quite like a traditional toilet, but it is connected to a composting unit that is 20 feet below the actual unit. With this type, you might need some plumbing knowledge to install it since you’ll need to connect the unit to the composter by using a plumbing pipe.

Waterless Composting Toilets

The last type is the waterless composting toilet. This type, as the name implies, does not require water. It uses an air flow type of mechanism that pushes the waste deep into the composter, which is found 20 feet below the actual unit. So if there happens to be a water shortage in your area, you don’t have to worry about doing your business.
