A septic tank or sewer system may not always be available especially as the water crisis worsens, an increasing number of environmentalists believe flushing toilets to be an environmental disaster, depending on who you ask.
For one thing, combining human faeces with significant amounts of water makes it considerably easier to transfer waste from remote sites like people’s houses to a central facility or waste treatment plant.
There has been a remedy to these problems for decades, it has only been in the last decade or so that these remedies such as the composting toilets, have become more widely accepted.
Composting toilets are gaining popularity and acceptance, thanks in part to the burgeoning RV, Off-Grid, and tiny home communities that lack access to contemporary plumbing systems.

The best composting toilets listed in this guide have been analysed based on their ease of use & installation, quality, functioning and environmental contribution. The products listed have been tested & tried to ensure a safe shopping experience.
Nature’s Head Self Contained Composting Toilet
Nature’s Head is one of the most innovative composting toilet manufacturers, and it is swiftly gaining market share. Their urine-diverting dry toilet is portable as well as stationary. It’s small and light, and it doesn’t take up much space.
It’s made of strong polyethylene and stainless-steel hardware to withstand whatever you throw at it. Nature’s Head toilets are self-contained and run on 12-volt electricity. This toilet comes with a 2.2-gallon urine bottle, a fan, and can be used almost anyplace. It comes with a 5-year warranty and will require a 2″ vent hose to be installed.
User feedback
The reviewers claim that liquid and solid separation is effortless, and that they only open the trap door to the solid’s container as necessary. There have been no odours after following the manufacturer’s directions and keeping the lid closed while not in use, as well as using the fan. Indeed, the faint odour that wouldn’t go away no matter how much or which chemicals were added to the black tank is no longer present.
When the urine jug fills up, the level rises above the edge of the base holding the container, leaving enough space at the top for you to empty it when it’s more convenient for you. Because the jug has a screw-on cap, there’s no risk of pee splashing out as you carry it into a restroom via the connected handle.
My verdict of the product:
Nature’s Head is the best overall. It is nicely designed and constructed, and it performs admirably. If you don’t like the placement, simply take it up and move it.
Pros
-
- Well designed
- Easy to clean & maintain
- Simple installation
Cons
- None so far

The Villa compost toilet was created to resemble a traditional toilet as closely as possible, making it easier for new users to adjust. It has on-grid capabilities as well as AC/DC variants for people who prefer to run it on 12 volts.
User feedback:
Customers like that this device is simple to install because all you have to do is install a vent pipe for odour elimination outside of the building, according to customer satisfaction and reviews. Users also like the company’s goal, which is to compost urine away from the home’s interior, so the urine is sent to a greywater system, a soak-away, or a tank away from the unit.
This unit also contains a ‘chimney’ stack that allows odours to escape the bathroom. Once filled, the solid waste falls into a bag-lined waste container that may be easily emptied. According to users, this composting toilet works flawlessly, has no stink, and the blower exhausts any odours outdoors.

Sun-Mar toilets are the perfect waste treatment solution because they can be installed almost anyplace and do not require any plumbing connections. With its self-contained Bio-drum that has been certified by the National Sanitation Foundation, this toilet offers a large capacity for composting.

Once solids have been broken down, they are delivered to a finishing drawer, while liquids are separated by a heating tray and air movement created by an internal vent fan. The Excel features a 2″ vent and is very easy to clean. Even though it will evaporate fluids, there is an emergency drain on the back of the device in case of excessive use.
User feedback
According to reviewers, the Excel toilet lasts considerably longer with more people using it before it needs to be emptied than the other toilets. Sun-Excel Mar’s model is at home in a residential setting and provides a self-contained, low-maintenance composting toilet solution for people without sewer or septic hookups.
This toilet has operated beautifully with two people full-time and is not even noisy, according to one customer. It has no stench and blends in well with the other bathroom fixtures, so it doesn’t scream composting toilet.

Buying Guide
Several important factors must be considered before making a poor decision. All other aspects of the products should be examined to ensure that you do not purchase something that will be uncomfortable. The most important elements to consider are listed below.
- Purpose: Composting toilets are popular for their environmental benefits, however mobile ready composting toilets are a little different. These are mostly intended for use while travelling. They are frequently powered by 12 volt systems or, in some cases, by an internal battery that can be refilled using a standard 120-volt power source, although the charge lasts for a long time.
- Environmental effects: Because microorganisms generate energy while conducting their activity, there is some heat generated throughout the composting process. However, when it comes to how rapidly they turn faeces into fertiliser, the temperature inside the chamber matters.
- Country laws: One famous compost toilet company has gone so far as to gain NSF certifications, allowing it to be installed in places where others might not be accepted. When questioned about composting toilets, the most common response is a blank expression because they had never heard of them before.
- Thickening ingredients: Some toilets require bulking material, which adds to the operating costs. Because the bulking ingredients are combined in with the solid waste, turning the crank to mix it all together is critical. This aids in the breakdown of trash by allowing oxygen to flow over and through it, speeding up the decomposition process. As a result, you may pay additional costs that are far too high for your comfortable existence.
This list is specially formulated to showcase the best composting toilet to ensure you invest in an environmentally friendly toilet setting, so you make a better-informed buying decision in the future.
FAQs
Can I use tissue or toilet paper in a compost toilet?
Unlike RVs and camper toilet systems, composting toilets do not require special toilet tissue. Composting toilets are excellent at breaking down any toilet tissue you throw in with the human waste.
Will my composting toilet have to deal with insects?
You’d think that having a storage tank full of human excrement in your home would attract wildlife, but it doesn’t. Because there is no odour, most insects, bugs, and even rodents are attracted by their sense of smell. Insects aren’t a concern for the vast majority of composting toilet users.
What is the best way to clean a composting toilet?
For any sanitation needs, most composting toilet users keep a tiny spray bottle filled with vinegar and water or baking soda and water mixture. Simply spray and wipe to remove. To keep additional moisture out of the system, don’t spray too much.
What is the definition of a composting toilet?
In a nutshell, a composting toilet is a human waste management technology that can be used when regular sewer or septic systems are unavailable or inconvenient. Composting toilets break down human waste, evaporate or at least separate the liquids, and naturally decompose the waste back into usable, nutrient-rich compost rather than dropping waste (solids and liquids) into a hole in the ground, burying the hole, and moving the outhouse.
Final Verdict
As long as environmental problems dominate the news, we’ll continue to develop new and imaginative ways to improve our way of life. It is up to each of us to make little adjustments that will improve our planet’s health. As the water crisis worsens, we’ll recognize how critical clean water is for not only ourselves, but for the billions of others with whom we share the planet.
I recommend the Nature’s Head Self Contained Composting Toilet and the second is the OGO™ Compost Toilet, both offer effective cleanliness, durability and environmental safety.
