The composting toilet was originally intended for boats and RVs. Therefore, it is compact and small in size.

Many people are using it for their homes and cabins today. It is possible to get around 90 times the use before you empty it. You’ll need to clean the bladder each throughout the day.

It is fully self-contained and has a dual-chamber system. One chamber is designed for urine while the second chamber is designed for solids.

How to Use

For the composting toilet to be used you must first add peat moss (or other dry carbon material) to the chamber that holds the solids. When someone is #2, turn the handle for the agitator on the other side. The handle rotates the waste inside the chamber, ensuring it remains in aeration. There is no need to do anything following urination.

Installation and Electricity

You’ll need to connect your outside vent. If you’re planning to install the toilet in an outside space it is just a matter of connecting with the pipe for venting to one leading out to the outside. In the indoor space, it could be slightly more difficult in particular if you plan to put the toilet in a location with no plumbing venting. But, it might simply mean making a tiny opening in the wall for an exhaust pipe to be taken out of.

It is also necessary to connect your toilet to an electrical source. The electric power will be used to power the fan in the vent. If the power is cut off the composting toilet will continue to function. However, some smells might occur. Most toilets that compost (even with vents) isn’t odorless. However, to be wise, you may need to flush it more frequently in the event of power outages.

Notes: There is just one composting toilet model from Nature’s Head. You can however get it with the “standard handle” or a “spider handle.” The difference is that the handle with the spider takes up less space to the side, which is ideal if you’re installing your toilet in a small space.

This wall-mounted Separett Villa 9215 has received praise from those who have used composting toilets previously.

This model is a dry composting toilet, which means there’s no liquid to cause unpleasant smells. However, there is a continuous fan that is built into the unit to further reduce the risk.

Separett is one of the brands that originated in Europe however it’s now to customers in the USA. Their toilets are designed to look like normal flush toilets as close as possible to ensure that visitors won’t be misled or dissuaded when using them.

Separett Villa is probably the most efficient composting toilet that you can utilize. It has one significant disadvantage in that you cannot move the chamber by hand. If power is cut off it won’t allow the chamber to be turned and composting can slow. Therefore, this is the most effective option if you have a reliable off-grid power source.

Utilized in a range of locations, from camping to tiny houses, users have noted that the composting toilet is simple to install even for those who are new to the concept and is easy to use.

One of the most popular features of this toilet for composting is that you don’t need to view the interior of the solids bin, and there’s no a necessity for compost medium and the churning process.

For single use to families with 10 people, there aren’t any issues and the toilet is suitable for use in high temperatures with no difficulties.

The main difference between this one, as well as the one provided by Nature’s Head, is that they are equipped with an electric rotator. it is not necessary to turn the toilet each time you visit Separett Villa 9215.

To start, put some peat moss within the chamber. It is not necessary to do anything else except periodically empty the waste chamber. If the urine chamber is designed to flow into your regular water drains, you don’t need to empty a bladder.

Installation and Power

For the installation of your composter toilet, it is necessary to have an energy source to run the chamber’s rotation and vent fan. It runs using AC and DC energy, which is perfect if you’re switching between regular electricity and off-grid.

It can connect to direct vents or vents with the size of US pipes. The entire direct venting apparatus is part of this composting toilet. The fan can operate with venting as high as 20.

The liquids can be designed to run into a drainage system. You can also allow the liquids to drain into the container (which needs to be manually emptied) or into an external system of filtration, like the sand bed outside of the bath.

We’d suggest Separett Villa 9215 as a good choice. Separett Villa 9215 is for people seeking a great composting toilet for areas that do not have sewer lines or septic fields. The only negative reviewers have mentioned is that it’s expensive but relative to other toilets that compost that are this good, we feel that the cost is comparable.

How to choose the Best composting toilet for off-grid?

Parts of a Composting Toilet

Most composting toilets off-grid are constructed to look like flush toilets as closely as possible. There is an empty bowl, a seat, and a lever for flushing. However, no water will be released during flushing.

To keep the bowl clean The majority of manufacturers recommend spraying it with a small amount of vinegar following each use.

The other components of compost toilets are different, however. There are a few variations between the types and models of compost toilets. However, these are the main components that you will see:

1. Urine-Diversion Device

It is crucial to segregate urine from solid waste. In the absence of this, the nitrogen content and the moisture content will be too high for waste to be composted quickly.

The compost toilet urine diverters are simple, but they work effectively. A funnel-like form allows urine to flow down the tube before it is pumped into an aeration device. If the tank of urine is full and it is empty, it can be disposed of outdoors in a safe manner.

2. Waste Chamber

After the use of the toilet is where the waste is disposed of. Prior to installing a compost toilet, you must add compost material to the bottom of the toilet, like sawdust or peat moss. When you empty the chamber you’ll need to add new material.

In the model of composting toilets, there might be several chambers. The final chamber is called the “finishing” chamber where composting waste is finished.

When the waste has been removed from the chamber, it’s allowed to be spread throughout your garden. The multi-chamber composting toilets are huge, but they are typically not portable.

The most advanced compost toilets are equipped with sensors and thermostats within the chamber. The toilet is able to automatically adjust the temperature to ensure that conditions are optimal for composting.

These toilets can cost a lot and generally do not work well for planning an emergency plan or off-grid.

3. Agitator

When you clean out the waste area of compost toilets make sure to include a little sawdust or peat. After that, you must turn the toilet.

For this, the portable compost toilets come with handles on the outside. The handle spins the chamber, causing it to vibrate and air it.

4. Fan and Vent

Venting the toilet’s cylinder allows more air to enter the waste within, aiding the growth of aerobic bacteria so that the process of composting is more efficient.

The vent can also help with any bad odors get rid of. A vent fan enhances the result, however, the fan requires electricity.

Other Considerations

Electric or Not?

Most portable compost toilets require electricity in order to function. Electricity powers motors to turn chambers and even regulates the temperature.

The presence of electric components means that composting is much more efficient. But the main caveat is that you’ll require electricity in order for your composting toilet to function.

For instance, if a blackout occurs, or you need to fix your solar panels, your toilet might not function.

Remember this when making your decision. It’s good to have all those electronic features, however:

  • You must ensure that it will function without power or
  • It is essential to have a reliable source that is energy-efficient (such for example, an energy source that can be used in emergencies).


As I mentioned in the post about the sun-mar composting toilets typically, you want a composting toilet that can help to divert urine.

If it’s not, the compost will become too wet, and smelly anaerobic bacteria can grow. It takes a long time to obtain an organic fertilizer that is clean in the case of compost that is too moist. The nitrogen in urine can also hinder composting.

The only reason it’s acceptable is to not divert urine in the event that the waste is being pumped into an outside tank or ground pit. The pit or tank can be lined by sand to ensure the water drains away.

However, these kinds of pits aren’t permitted everywhere due to the risk that the waste will pollute groundwater.

The final word? Make sure you use composting toilets with urine division.


In principle, it doesn’t be a problem if your composting toilet’s design looks like this.

If you are planning to have guests over it’s very beneficial that your composting toilet looks like the normal toilet as closely as you can. If not, your guests may be confused about how to operate it.

It is helpful to place posters in your bathroom that explains to guests how to utilize the toilet. Nature’s Head has one that you can download and print here (PDF).
