  • Extra deep bowl for greater comfort

First on the list is this low priced toilet that leaves everything to the imagination with its design but does a great job in making up for it with features. Available in an 18 and 24 liter model, although this won’t win any beauty contests it will handle anything you can throw at it. The piston pump is replaceable and the bowl itself is cleaned thoroughly with the two directional rinse. Streaks and other waste remnants aren’t left behind, and it is comparable to a home residential model in terms of strength.

To prevent any type of splashing or discomfort the bowl is extra deep, and when not in use the lid snaps close so that vibrations are not an issue when moving. Indicators that are in clear view let you know how much waste is in the toilet as well as how much fresh water is still available. It is an intuitive system that goes the extra mile of being easy rather than complicated. When the spout storage compartment needs to be cleaned, it can be detached and moved around at will. No more worries about all in one systems that are a pain to clean when you’re on the road. Some of the nicer extras associated with the unit is the holding tank for your cleaner so that you don’t have to carry it separate, and the hassle free packaging that it arrives in. There are many on the list but this is a solid starter for those that need a good composting toilet.

Up next is this low priced toilet that offers a futuristic polished look. It almost looks like a small space pod if you stare at it long enough, and it has a lot of desirable features like the first model on the list. The seat is loads more comfortable than the first item on the list, probably due to how sleek the material is. Sitting on this will give you a feeling of comfort like you were on your home toilet.

And with an optional hold down kit, the Potti 550E will probably be the easiest to handle when it gets full. This is the best toilet on the list, and also one of the best looking. If you make this purchase then it will be money well spent.

Another low priced option is this Camco 41541 portable toilet that has a nice big 5.3 gallon detachable holding tank. It’s one of the biggest on the list, and is made to detach without giving you a big headache. Odors and leakages are prevented with the sealing slide valve lock, a premier way to stop some of the biggest problems in composting toilets from literally spilling out. A heavy duty construction keeps it from falling apart when you need it the most, and it uses a bellow type flushing mechanism which is powerful enough for most needs.

Sticking with the low price is the infamous Porta Potti 550p that has the straightforward design of a composting toilet but a lot of extra features.

There isn’t a lot of beauty to this products design, but to be fair there is only about one item on the list that goes out of its way to look great. If you want a composting toilet that just does the job right then this model is all you will need.

What is a composting toilet?

Best Composting Toilet So, what is a compost toilet? Maybe you are here because you know you want to invest in a compostable toilet—or maybe you stumbled across waterless toilet systems while looking for an eco-friendly toilet to use in your little house, outdoor restrooms, or on camping trims—or are just researching alternative toilets to use.  Regardless of why you are here, you clearly are interested in the idea of waterless composting toilets—so let’s talk about what they are.

While composting toilets have been around for quite some time, they may be a foreign concept to some people who haven’t heard of them, or ever used one, before. A self-composting toilet is not just an outhouse or portable toilet—nowadays there are options for home use—but actually just a great eco-friendly option as well as a more budget friendly choice, especially for those of looking for a composting toilet for a tiny house.

When choosing a composting toilet, you will find that you have 2 designs to choose from—self-contained toilets and a central or remote composting toilet.

The self-contained composting toilet is more popular among RV users, tiny home dwellers, on boats, and even a great composting toilet for cabins or cottages. These toilets have a compost chamber that is placed under the toilet and often separate liquids from solids—of course this does depend on what model you end up going with.

The central or remote compost toilet will actually send your waste to a composter located somewhere else—these can actually be used in larger homes. If you want something more like the traditional toilet we are used, then this is the way to go.

Lastly, it is important to note, that of course there is still they “bucket” style composting toilet. These are really portable, affordable, and easy to use if you keep up with it.

How does a composting toilet work?

Best Composting Toilet So, how does a composting toilet work?? Well, regardless of what type of composting toilet you decide to go with, they are all made to do the same thing—some of them may just get the composting process done sooner rather than later.

The compost toilet, no matter which one you get, is designed to naturally decompose human waste and recycle into usable compost—which is great for the environment and can be mixed into your soil for fertilization purposes. A compostable toilet will be able to quickly (depending on the type of toilet you get) compost your waste and recyclable toilet paper, turn your waste into compost that is easy to handle and safe to use, and evaporate all liquid.

The liquid portion can be a little tricky depending on what type of toilet you have—some require you use a medium to turn it into a solid, while others have liquids and solids go to different chambers, so they are easily separated. The waterless toilet system you would use daily in your home will typically be those who can separate the two.

Having come this far, you may still be wondering how a compost toilet works. Once you have your waterless toilet set up you will need to choose a composting medium to use—some of your options can be coir, chopped straw, wood ash, sawdust, wood shavings, and even coffee grounds (to name a few). Choose they type of medium you prefer and what is convenient for you—and keep in mind that some will mask odors better than others, so just make sure to place special consideration on where your toilet will be located and how often it will be used.

Best Composting Toilet If you have a toilet that separates liquids from solids, you may have the option of “flushing” and/or may have a heated evaporation chamber to help get rid of all traces of liquids. Some of these may also require that you empty out the liquid chamber separate—it just depends on what model you get, so just keep this in mind as you narrow down your choices.

Solids, whether you have a bucket system or one that keeps liquids and solids separate, will mix with the compost you chose to use—make sure to cover waste every time the toilet is used in order to maximize composting time and keep odors at bay. Many users also find that keeping a mixture of vinegar and water—to use to spray the toilet bowl after use—also helps dissipate odors and keep the toilet area clean and smelling fresh.

Keep an eye on your toilet as it starts getting full. If you have a compost bin located outside you will want to make sure to take it out before it overflows—and if you have a bucket type system you will want to keep a replacement bucket on hand for when you need to empty out the other one. While you will want to rinse out the toilet (or bucket), make sure to keep it to a minimum so you don’t delay the composting process. The water and vinegar solution can be a great way to keep things clean and smelling fresh without destroying helpful bacteria that actually help the composting process along.

Remember, that no matter what type of composting toilet you get, they all have the same result. Some may get the process done much faster than others and some are more efficient for larger families—but in the end they all take human waste and convert into eco-friendly compost that can “give back” to the environment. Make sure to keep yourself up to date on local and state laws regarding compost disposal, to ensure that you are doing so both safely and properly.

Different types of Composting toilets and how to use a composting toilet

Best Composting Toilet If you have never used a compost toilet—AKA a waterless compost toilet—then you may have some questions. While how they work is a relatively similar process across the board, how to use a no water toilet can vary greatly depending on what type you end up getting. Below we will discuss some of the different types of composting toilets and how to use them.

Self-Contained

The self-contained composting toilet is a great option for residential use and can be used in the home. The can be electrical or non-electrical and offer lots of additional features most users will love!

If you go with an electric compost toilet, you will have a toilet that comes with a fan as well as a heating element. The fan will help dissipate odors and keep the area free of unwanted smells while the heating unit will help evaporate the liquids. You only have to plug it in when in use and the amount of power they use will vary between 80 and 150 watts, depending on the brand and model you decide to get.

Regardless of whether you get an electrical composter or a non-electrical unit, you will want to make sure that you get a toilet with the appropriate capacity. While electrical toilets may have higher composting capacity, if you don’t need something that has more then don’t pay for the additional capacity.

The best part about the self-contained toilet is that it can be used in the home without any plumbing—since it does not require water. However, you will need to assemble it correctly and ensure you take your time when putting together, and installing, the toilet’s vent stack. This toilet will also evaporate your liquids, so you don’t have to take the time to dump out the contents.

Overall, this composting toilet looks the most like the typical toilet found in the home and can handle use daily use. They are easy to clean and maintain as well—just make sure your home meets all of the requirements if you decide to go with an electrical model. These are also easy to use and keep clean—just do your business and use the additional features as needed.

Central

If you decide to go with a central composting toilet you will have two different types to choose from—a 1-pint flush system and a waterless system. Regardless of which one you decide to go with, they both will be connected to a compost unit located either in your basement or just outside your home.

The 1-pint flush is less eco-friendly, and many users may not define it as a “real” composting toilet, because it does require water and plumbing. Like the name suggests, it uses about one pint per flush—which is minimal compared to the traditional toilet (which is typically 1.6 gallons per flush instead of just a pint). This toilet’s composting unit will be installed no farther than 20 feet away from a toilet and will require a plumbing pipe that leads from the toilet to the composter. As you can see, this is still an eco-friendly toilet that uses minimal water and is a great option for residential use. As far as how to use this one, it is pretty much like your typical toilet for the most part, so there really isn’t anything different outside of the fact that it uses much less water and transports waste to a composting unit instead to the sewer.

The waterless central system composting toilet, on the other hand, uses absolutely no water. However, it does also require a plumbing pipe that leads directly to the composting unit and uses an air flow unit to transfer the waste from the toilet to the compost unit. These are a great water saving option for those of you who live in dry areas, want to save money, or just want a more cost-effective toilet in your vacation home or cabin. This toilet is really easy to use and similar to your everyday toilet. While it doesn’t flush like a traditional toilet, it is similar to most residential toilets so, if you decide to use one of these in your home, it shouldn’t take to long to adapt.

Split-Systems

The split system composting toilet has become really popular over the years. Not only does it simplify your life and make using a composting toilet much easier, but it also is much more affordable than some of the other high-tech residential type composting toilets

This type of composting toilet, like its name suggests, is split into two different areas—the pedestal and the tank. The pedestal is the toilet area where you sit and the tank is located underneath the pedestal and houses the waste. These are great for home use and typically separate the liquid from the waste, although there are some that still employ the “bucket” type system (which we will discuss later on). Either way, these are more similar to a residential toilet as well and are easy to use. Just keep track of the tank because you will need to dump it in your compost bin as it fills up—an you don’t want to wait until it is too full.

You might also be interested to learn more about tankless toilets or how to choose the perfect macerating toilet.

RV composting toilets

A composting RV toiletis designed for RV use, but some are actually portable enough to also use on camping trips or road trips (although the latter would fall under multi-functional portable toilets. RV toilets can be similar to traditional toilets or they can be bucket toilets—but most often they fall somewhere in between and are most like the split system composting toilet.

Typically, an RV has the black tank that holds your waste and that you have to empty out in specified locations. However, if use a composting toilet in your RV you will eliminate the need for use of this tank, will no longer need any chemicals, and won’t have to flush anymore!

These toilets will typically have the seating area and a tank below. Some may have a separate container for liquids and solids, while others may employ the bucket type system. Regardless of which one you use, these are easy to keep clean—just keep some water and vinegar solution nearby and spray it when necessary, or every time it is used if you prefer. The best part about these is that the you can save the compost material to take home or easily dispose of it anywhere your state and local areas allow. So, no more emptying out the black tank or dealing with any plumbing issues with this one!

The best part about using the composting toilet is that it helps you save money in the long run and is really cost-effective both initially and in the long run—so, if you want to save money and help the environment, then this is definitely the way to go.

Portable composting toilets are really easy to setup and use—in fact, they are actually the easiest to use since they are so simplistic and minimalistic. Many people, and actual users, often refer to them as “bucket toilets” but nowadays they are more than just that.

You will find that you have the option to buy collapsible portable composting toilets or one that comes setup and ready to go. If you know you have limited space, or if you just want something that is easy to carry, we highly recommend you purchase one of the more easily packable options.

Once you have gotten your composting toilet setup is easy—we are specifically referring to portable composting toilets, so if you are looking for something permanent to use in your home or for the best RV composting toilet, then the set up will be different then what we are describing here.

First and foremost, if you are camping (either short term or long term) you will want to setup your toilet somewhere where you and your campmates feel safe yet still have privacy when it is in use—and the last thing you want is any unwanted smells nearby when you are trying to eat or relax.

Once you have found the perfect spot you will need to set up your toilet. Now, it is important to note that you can choose to get a split composting toilet, which has separate holders for liquids from solids, or a more traditional “bucket” type which holds it all together. Regardless of which one you get, you will want to line the holding tank—or if it is a bucket type, then the bucket—with the composting bags designed for the toilet you have.

When you have done that you will want to add some compost medium before using it—whether it is coconut coir, peat moss, grass clippings, cedar sawdust, mulch, or whatever you find works best for you. Keep in mind that different types of composting mediums speed up the composting process more than others, so if you plan on using your compost material then you may want to go with one of those.

Make sure every time the toilet is use that it is covered with composting material. Whether you have a separate liquid holder or not, you will want to cover it as well so it can be solidified and easy to dispose of or use later on. If more than one person is using the toilet you will want to ensure they all know to do this—this will prevent odors from arising, keep insects at bay, and ensure everyone has a clean toilet to use every time. Lastly, we also recommend you always install the overflow hose if there is one—because you just never know!

Once the toilet is full, or if it’s time to leave the campsite you can choose to dispose of it properly or if you want to use it as compost material and have a drum for it at home you can bring it along with you—just make sure to secure it properly on your drive.

If you are in an RV, you can safely dispose of your waste at dump or dumpster—just make

sure, that you use a composting bag and to secure it properly before disposing it. Since landfills have laws in place to allow for human waste—for example, diapers—this is allowed as long as it is done in a cleanly and appropriate manner.

If you are out camping or in a national park, make sure to take a look at the park’s specific rules. Some may be more lenient than others when it comes to composting toilet—but it is important to be sure since disposing of your waste incorrectly could harm the environment, including any wildlife that may be in the area.

“Bucket” composting toilet

Last but not least, let’s talk about the bucket composting toilet. By now you may have heard this term and may be wondering what we mean—or maybe you have used one of these and already assume the worst. However, you shouldn’t because these are super easy to use and a great versatile option. You can use these in your tiny home, take them on camping trips, install them in your RV, and so much more!

The bucket toilet system can be, as the name suggests, a simple bucket—or it can be a bucket placed under a pedestal and built in area. So, you can still have a toilet bowl to sit on as well as keep the bucket out of sight.

While the bucket system is pretty easy to use, it does take some time to get used to it if you have never (or rarely) used it before.

First and foremost, the bucket toilet will require special composting bags. While there are some pretty generic options when it comes to these, but if you purchase a whole system you may need to stick to the bags made for that specific toilet. And, of course, like all compost toilets, you will need to use a composting medium to set up your toilet and cover up your waste as you go.

Since these toilets need to be emptied and don’t lead directly to a composting unit, you will want to set up a composting drum where you can empty the waste out. Make sure to cover it up and place it in a shady area—the waste will compost in the drum and you will be able to use for gardening and fertilizing once it is done, if you’d like to of course.

It is important to note here that bucket toilets will take a little longer to compost everything since you have to take it out and have less control over some factors. However, this isn’t a huge difference and if you have a tiny home this may be the perfect composting toilet for you.

The composting toilets we mentioned above are a little easier to keep odor free—some of them have fans, others evaporate your liquids, and some have a composting unit you install away from the toilet. However, you will find that if you use the bucket toilet correctly and keep up with it you will easily keep odors at bay as well.

To keep it smelling fresh, make sure to keep it use cover material when you empty the bucket, before its first use and every time you use it just make sure to cover it up well every time. While you don’t have to clean it out with chemicals or scrub it down when you empty it out it does help to hose it down and let it dry completely—this means you should have more than one bucket on hand so you don’t have to worry about having to use the bathroom while waiting to clean and dry the bucket that you just emptied. Lastly, if you are using a composting bucket in your tiny home, you may want to invest in bathroom extractor fan to help everything circulate and prevent it from standing still.

While there are a lot of composting mediums to choose from, if you are using a bucket toilet, you will want something that covers the smell better than others. Many users report the tree best options for the bucket toilet system is semi-composted mulch or wood chips, regular mulch or wood chips, and cedar sawdust. These three options effectively cover odors and keep them at bay by masking them with there own natural smells.

Batch Units VS Continuous Units

One last thing we want to cover in this section is the difference between batch units and continuous units. While these aren’t types of toilets, they are the two different ways in which composting toilets work.

Batch composting toilets will have two or more bins and are most popular in self-contained composting toilets. Once one of the bins is full you move it outside and let the waste compost for about 6 weeks, then you bury it—make sure to follow your local and state guidelines when doing so.  These units often provide heating options to help evaporate liquid, may have electrical ventilation features (fans), and are more complicated to install—but in the long run are a great for residential use. The batch unit also allows for more than one composting toilet system to be used in the home.

On the other hand, continuous composting toilets only have one chamber for all waste, both liquid and solid—although there are split system options nowadays. Since they typically have one chamber, they will need a way to drain any excess liquid the toilet may have, and you will definitely need a good compost medium to help mask odors over time.

Pros and Cons of using a composting toilet

Like everything in life, there is both good and bad to everything. No matter how awesome a composting toilet is, it is important to be aware of all of their Pros and Cons before making your final decision and purchase.

PROS

Let’s look at all the good that comes with investing in a composting toilet—because there are a lot of great things that come with it.

First and foremost, composting toilets are extremely portable. They are lightweight, easy to use, and you can take them away. Whether you go with a bucket system or one that has a waste compartment, you will have no trouble taking your compost toilet with you wherever you need to go.

Secondly, compost toilets are available for all types of uses. Nowadays there are loads of residential options that you can use in your home or tiny home, options for your RV, and of course portable selections. No matter what your needs are, a composting toilet is so much more than a bucket toilet nowadays.

Composting toilets are also really easy to keep up. Not only are they great for the environment and a great eco-friendly option, but they are also really easy to use. As long as you have the right composting medium and keep up with maintenance, you will have something that will remain odor free and be easy to use.

Next, cleaning a composting toilet is super easy. Whether you have a portable composting toilet, a bucket type composting system, or one made for residential or tiny home use, you will find that once you get used to the composting life you will find that keeping your toilet clean is super easy and don’t require heavy duty deodorizers, cleaners or holding tanks.

Lastly, the best part about composting toilets is that they are really durable and come at a great price. Whether you invest in a more complex residential system or in a bucket system, composting toilets are built to last you for the long haul. Some of you may be asking yourself well is it worth it if composting toilets smell ruins the bathroom and feel of my home? Well, lucky for you it is actually easy to keep odors at bay if you use the composting medium as prescribed and keep a mixture of water and vinegar nearby to spray as needed.

CONS

Like everything in life, composting toilets have several cons that you need to look out for.

First and foremost, you need to make sure that a composting system is right for you. While they are easy to use, they do have a time period to get used to using them and you will have to set them up appropriately as well as make sure you have a compost bin if you are using one that doesn’t come with a composting unit.

Another thing to look out for is that not all types of composting toilets will work for you. If you want to install more than one unit you will want to go with the appropriate toilet because choosing the wrong one can be costly. Make sure to take your space, needs, and use into consideration.

One main problem user will run into is dealing with temperature regulation. Overexposure to heat or freezing conditions can mess with how it functions and prove to be costly over time.

Some units come with preventative measures for this, like fans and heating features, however, not all of them do—so make sure to invest in the best option for you. Another important thing to remember is that you need to use the right type of dissolving toilet paper to get the most out of your system. While some can handle any type or brand, most may get clogged or damaged if you use the wrong one.
