BUYING GUIDE: HOW TO FIND THE BEST COMPOSTING TOILET FOR OFF GRID

It is critical that you spend your money on a high-quality composting toilet. Some things to keep in mind when purchasing a composting toilet. Let us now guide you in finding the best composting toilet for off grid:

best off grid toilet

√ Installation Ease

There are various questions you need to ask yourself here, but they all have to do with plumbing. What if you don’t know how to install a toilet yourself but want it sent pre-assembled? If you’re looking for a fast and simple way to install a composting toilet, you may go with the pre-assembled model. As a competent builder, you may find the prospect of building your own off-grid toilet system appealing. Installation expenses may be greatly reduced if you build your own.

√ Maintenance

The upkeep needs of various off-grid toilet systems vary. Some systems need daily emptying, while others require daily stirring, and this varies with capacity; high-end systems require less care. Determine how often you will use the toilet before purchasing a composting toilet system. However, if you put a composting toilet outside, you will have to dig a fresh pit, which may entail a lot of physical exertion, on a regular basis.

√ Size

There should be no surprises when it comes to where the toilet will go, whether it’s in your home or an outhouse or a cottage you’re building just for the purpose. If your toilet has a fan, you’ll also need a place to put a ventilation pipe, which means you’ll need a power supply. With a crank handle, you’ll need a lot of floor area to turn it.

√ Ventilation

Using a fan in conjunction with a composting toilet is a common method for removing excess moisture and dealing with any smells that may be present in the drum. As a result, a pipe venting this outside must be installed, which necessitates drilling a hole in the wall. Additionally, some are not constructed with normal plumbing-sized hoses, making installation more difficult.

To use one of these toilets, you’ll need an off-grid generator since the 12V fans they typically include need a power source to operate.

√ Capacity

Depending on how often you want to use the composting toilet, the size of the drum is critical. You’ll want a bigger drum if it’s going to be used by the whole family every day so you don’t have to empty it as often. If you’re building a vacation house or cabin that will only be used for a few weekends a year, you may want to go with a lower capacity.

There is a greater likelihood of frequent emptying of the pee tank in compost toilets that segregate liquid waste from solid waste.

√ Temperature

The importance of an off-grid toilet system is amplified in hot climates. Off-grid toilet systems are more difficult to maintain in hotter areas. With maggots and flies becoming a major issue in even the most well-maintained systems, it’s important to keep an eye on things.

Using an outhouse toilet in the dead of winter or the wee hours of the night may be downright dangerous. Consequently, the location of your off-grid toilet depends on the temperature.

√ Disposal of Waste

Consider how you’ll dispose of the waste from your compost toilet system before purchasing one for your off-grid farm. Composting toilets may be connected to septic tanks if you already have one. A little study might help you choose which system to employ with the on-site waste idea since people create a lot of urine, feces, and used toilet paper.

√ Price

They’re a lot of money! Think twice before jumping to conclusions about price and quality in this scenario. Read all the features and observe what materials are utilized for each hardware item, and so forth. Furthermore, despite the fact that their prices have risen, you should not be discouraged. Because you’ll save a ton of money and get to keep the compost soil you create for your garden.

BEST COMPOSTING TOILET FOR OFF GRID – 2022 REVIEWED

In this first segment, we review seven of the best composting toilet for off grid on the market as of now:

1. BEST OFF GRID COMPOSTING TOILET: NATURE'S HEAD DRY COMPOSTING TOILET WITH STANDARD CRANK HANDLE

CHECK LATEST PRICE

This composting toilet from Nature’s Head is quite simple to set up and use, and it looks and feels exactly the same as the toilets that are piped in that you are accustomed to using. The distinction arises from the manner in which the trash is handled. Keeping urine and solids in separate containers that are both simple to empty helps to keep smells contained and out of the way.

It comes with a five-foot vent line, allowing you to be flexible with where you put it; however, the vent hose can be quickly removed so that you may empty it and give it a thorough cleaning.

This low-energy composting toilet is equipped with a power outlet that operates at 12 volts, so it won’t need an excessive amount of electricity from your generator to run the extractor fan. It is not appropriate for those who do not have access to some kind of power source, such as a generator.

2. BEST COMPOSTING TOILET FOR OFF GRID: NATURE'S HEAD SELF CONTAINED COMPOSTING TOILET

CHECK LATEST PRICE

Another one from Nature’s Head, this time with a spider handle rather than the more common crank handle. This makes it possible for the peat moss in the drum to be churned somewhat more smoothly, which enables the excrement to be buried more quickly, hence reducing the likelihood of odors escaping.

The rapid and easy operation, made possible by the spider handle’s ability to be turned easily, is perfect for confined places and is user-friendly enough for children.

In the same way that the model shown above does, this one also has two distinct chambers to keep liquids and solids apart. Because of how heavy the drum may get when it is full, emptying it may be challenging for certain individuals, especially those who live alone or who are old.

3. BEST OFF GRID TOILET: SUN-MAR CORP CCEB-02510 CENTREX 2000 WITH A 1" DRAIN HOSE

CHECK LATEST PRICE

The non-electric central composting system that Sun-model Mar’s CENTREX 3000 NE is, which brings us to our last recommendation for the finest composting toilet, rounds off our list. This composting toilet is among the best of its kind and can manage a significant amount of waste. This composting toilet is the ideal option for usage off the grid since it has a continuous flow mechanism that moves the compost over a lengthy drum and then deposits it into the collecting unit.

Therefore, you do not need to bother about rotating the drum in the opposite direction in order to empty it. According to the evaluations of composting toilets, it is readily capable of accommodating up to five individuals for daily home usage and as many as eight adults for occasional or weekend use. There is also the possibility of integrating a 12 V fan into the system, in addition to the odor-free ventilation stack that measures 4 inches and comes standard with the system. Emptying the composting unit is necessary once every few months in the event that it is used often, and once or twice a year in the event that it is used seldom.

The CENTREX 3000 central is delivered completely put together. Simply connecting it to a gravity-fed toilet that uses little water is all that is required for it to function well even in the absence of an external power source, making it the ideal composting toilet for use in off-the-grid environments. Depending on the needs of the organization, this central composting toilet may potentially be linked to several other toilets. Users who do not want the inconvenience of emptying the toilet regularly may consider purchasing this best off-grid composting toilet, even if it comes at a little premium price. This toilet is worth the investment.

4. BEST TOILET FOR OFF GRID LIVING: SEPARETT VILLA 9215 AC/DC

CHECK LATEST PRICE

Instead of being developed for boats, RVs, or even smaller residences like tiny homes, the Villa 9215 was intended to be permanently installed into a homestead. Because of the wider ventilation system, it is compatible with normal plumbing diameters in the United States, and because of the change in fan type, it is capable of operating on either AC or DC power.

Because the fan and vent have been upgraded, any extra moisture may now be evacuated farther away from the unit, which should prevent any unpleasant odors from being noticeable in the area around the toilet.

This toilet does not need any organic matter such as peat moss, coconut husks, or any other kind of organic matter since the fan is designed to pull out moisture and remove any odors that may be present in the drum. The fan has just one speed, thus it cannot be changed to improve the rate of ventilation if that becomes necessary.

5. BEST OFF GRID TOILET SYSTEM: SUN-MAR EXCEL NON-ELECTRIC SELF-CONTAINED

CHECK LATEST PRICE

The Sun-Mar Excel is the only toilet on the market that can work without the need of any kind of electricity source; thus, if you are living completely off the grid, this is the product that you should choose. It is also an excellent choice for any area with limited space, as well as for those who want to live a lifestyle that is less taxing on the environment by relieving part of the strain placed on the sewage system.

The revolving Bio-Drum is not only simple to use, but it also ensures that the compost is well mixed, aerated, and that any moisture is evenly distributed throughout while also being quickly drained away.

An evaporation chamber can be found underneath this drum. This chamber removes any extra liquids and moisture from the compost, which in turn helps it to dry out and degrade more quickly. If you pee, you let it be; if you defecate, you add a scoop. After that, mixing is done every two days using the “churning” handle. Sun-Mar has a philosophy that helps make using the Excel very simple: “if you pee, you let it be; if you poop, you add a scoop.”

6. BEST TOILET FOR OFF GRID LIVING: CAMCO PORTABLE COMPOST TOILET

CHECK LATEST PRICE

Common reviews of composting toilets indicate that the Camco portable compost toilet, which is suitable for use when camping or traveling in an RV, is the next best composting toilet that you may take into consideration. Because the flush tank is coupled to the waste storage tank with solid latches, this composting toilet is the most cheap and best one for usage off-grid. It also makes the whole unit easy to travel around from place to place. Even though both solid and liquid wastes are deposited into the same holding tank, this tank is protected from contamination thanks to a sliding gate valve that is both watertight and odorless. You have nothing to worry about in terms of any nasty spills.

It takes just 2.5 gallons of water per flush for this top-rated composting toilet to remove waste from the bowl, which is almost half of the amount of water that traditional flushing toilets use. This demonstrates the best composting toilet’s capacity to conserve water and is one of the reasons it has received such high ratings. The flush tank has its own dedicated cap located below the lid, which can be used to add water to the tank. However, in order to utilize the flush, the other cab has to be pulled down. You may also purchase Camco TST to deodorize the toilet and partly treat trash before it is disposed of. This product also treats waste. The seat may be easily wiped clean and provides a pleasant sitting experience. Even though it has received many positive reviews, this composting toilet is not suitable for use in a home since the waste tank it contains is not particularly large, and it must be emptied once daily. Because of this, it is the ideal composting toilet for use away from the grid as well as for usage in an emergency.

7. BEST OFF THE GRID TOILET: PORTA POTTI 92306 WHITE THETFORD CORP

CHECK LATEST PRICE

Check out the Porta Potti by Thetford if you are looking for the best composting toilet on the market today, which also has a contemporary design and comfy seats. The extended bowl of this portable toilet, which delivers a homelike sensation when doing your poo business on an RV, while camping, or while living off the grid, is largely responsible for the positive reviews of composting toilets that have been written about it. This battery-operated flush is included with the finest composting toilet for use off the grid. Both the clean water flush tank, which has a capacity of up to 4 gallons, and the waste tank, which can contain up to 5.5 gallons of waste, need to be emptied every day. This is the composting toilet that customers have ranked as being the best overall, and it comes with a flush, a holder for toilet paper, a water-level indicator, a comfy seat, a cistern, and a cover. Due to the fact that it is fastened with a seal valve, the bottom portion of the toilet is also impervious to odors and leaks. The valve eliminates the possibility of any splashbacks occurring, and the revolving pour-out spout makes it simple to dispose of trash. You may prevent waste from sticking to the bowl of this toilet by using the “add water” button, which is another helpful feature that makes this toilet one of the best composting toilets available.

FREQUENTLY ASKED QUESTIONS (FAQs)

We finish off by answering some of the common questions about the best composting toilet for off grid:

best off grid toilet system

Q1. How do composting toilets function?

A. Composting toilets are a plumbing-free alternative to a standard flushing toilet; in fact, they don’t need any more water at all to function properly! The trash is broken down by the use of the natural process of decomposition, which is how they operate.

A vent system is used to evaporate any water that may be present in human waste, and the resulting vapor is discharged into the atmosphere. Since human waste is composed of around 90 percent water, this amounts to a significant volume of liquid.

After the process of decomposition, the solids that are left behind create useful fertilizing soil, which is great for applying to plants or trees. During the composting process, any pathogens or viruses are degraded by microorganisms, making the remaining soil safe to use. Additionally, composting is an excellent method to save money on the purchase of commercial fertilizers.

In order to operate properly, composting toilets need the ideal combination of moisture, oxygen, heat, and organic material. This combination produces the optimal setting for aerobic bacteria to do their transformational job in the composting process.

Q5. Do composting toilets have a bad odor?

A. Now that we have your attention, we are sure that you are wondering something along the lines of “surely all of that wastewater is going to kick up a stench when it evaporates?” The vent system, on the other hand, is intended to get rid of any odors that may be present and to facilitate odorless dissipation. Because of this, when you use this form of off-grid toilet, you won’t have to worry about obtaining smells of pee or feces carried by the wind.

As long as you are maintaining your composting toilet in the right manner, there should be almost little odor produced by the solid wastes that are left behind to degrade into usable soil. This is the case even if you are composting human waste. It is recommended that composting toilets be cleaned once every six to eight months to prevent unpleasant odors and overflowing contents.

A handy hint: to maintain a pleasant aroma in your toilet, sprinkle some used coffee grinds into the drum. You may ask your neighborhood coffee shop to save the coffee grounds for you, preventing them from being thrown away and providing you with more material for your compost pile in the process.

Q3. Does a composting toilet accept toilet paper?

A. Yes. You are welcome to make use of toilet paper; however, you should choose a kind that is rated for use in RVs or marine environments to guarantee that it will decompose more quickly and will not introduce any colours or inks into your compost. The lower the number of plies, the more quickly it will degrade in the drum.

It is possible that having a container for used toilet paper from the number one stall would reduce the amount of paper that accumulates in the area behind the toilet. When less tissue is used, the drum will need to be emptied less often, which will save time.

Final verdict

Composting toilets are becoming more popular among those who live off the grid since they do not smell or attract flies. There are a variety of compost toilet systems to choose from, which necessitates some study.

The capacity, maintenance, ease of installation, plumbing requirements, waste disposal, and temperature levels in your area can all influence your decision-making in this regard. You should conduct your research before deciding on a particular composting toilet.
