Buyer’s Guide

There are a couple of things that you will have to remember when buying a composting toilet.


If you want to have a composting toilet in your RV, you have to make sure that you have enough room. Some models take up more space than others. You will have to get exact measurements. You also need to keep in mind the measurement of the handle, so it has room to function.


You have to make sure there is a proper way for the toilet’s exhaust vent to reach the outside. For this, you may have to cut a hole to accommodate it. The toilets aren’t very moveable, as they are made to be bolted to the floor.

In addition, you will need a 12-volt fan for ventilation of the compost. This fan will need a battery system to give it power. Despite all these requirements, people find it easy to install composting toilets.

Diverting the Urine

It is highly recommended that urine be diverted into a separate container so the other waste can compost faster. Containers for urine can be found near the main composting bowl, which you’ll have to open to reach the urine tank. There are models that keep the urine tank outside the toilet for ease of use. This could cause an unpleasant smell when opened, however.


Not all composting toilets are going to be comfortable. Be sure to check out the reviews of buyers who have tested the toilets. Some are more narrow than others, and some models require men to sit down while urinating. Be sure the model you want to buy is going to be one you want to sit on.

Quick Tip

If you are uncertain of whether you will be using your RV for a very long time or just a few weeks, here’s a tip. Use wood when installing the toilet. You can install it on a piece of water-resistant plywood. This way, you can remove it and reinstall it as you wish without needing to replace the floor. You can save yourself a lot of time and money.


You may have a couple of questions about the use and value of composting toilets. Here, we will discuss the benefits and drawbacks of these toilets. We will also look at what composting toilets are and how they work.

What exactly is a composting toilet?

This specific kind of toilet was born out of people’s need to get rid of their own waste. It’s believed the ancient Chinese are the first ones to come up with the idea of using this waste removal system productively.

Basically, poop and urine are collected in a toilet that doesn’t use water. Bacteria and other agents are mixed with this waste to create compost over time. The toilet will compact this waste if maintained properly.

How does a composting toilet work?

It’s a pretty basic idea that not many people know about or are comfortable with learning about. In order to function properly, a composting toilet needs oxygen, moisture, and warmth.

Composting toilets look very similar to normal toilets and are just as comfortable. After using the toilet, you would add a scoop of bulking agents (which can be sawdust or coconut fibers, for example). You will then turn a handle to mix everything.

Some toilets do this automatically. Anaerobic bacteria will then break down the waste by using oxygen. Your toilet will need to evaporate any excess moisture. For this, many toilets have separate containers so you can dump urine on its own.

It is vital that the bacteria in your toilet have enough oxygen, and the temperature needs to be properly maintained. You must always check that the temperature is somewhere around 55 degrees or warmer; that is the ideal recommended temperature for the best results.

Once the waste has become compost, you will slide it out of the toilet’s finishing chamber and dump it.

What is the point of a composting toilet?

You may find yourself wondering just what the point is of getting a composting toilet. Well, let’s take a look, shall we?

No nasty drainage issues​​​​

Draining a septic tank is not fun. If you’ve traveled in an RV before, you will know it is an unpleasant thing to take care of. By using a composting toilet, you can avoid all that nastiness.

Save water

These kinds of toilets are much better for the environment than normal ones — it saves a lot of water. Some toilets use up to 7 gallons of water per flush, with newer ones using 1 gallon, but it’s still a lot.

Create compost

One person’s composting toilet usage for one year will create about 80 pounds of compost, which is not too shabby. You can use your homemade compost to feed your plants if there aren’t any laws that prevent you from doing this in your area.


A great benefit of using a composting toilet in an RV is that it is very versatile. You can even use the toilet at home if you’re not traveling. This way, you can be saving water whenever you want to. You can also use these toilets while out camping for a few days or weeks. This environment-friendly toilet can be used in any environment.

Save money

Obviously, when you are using a toilet like this, you will be saving money on water bills. Although many composting toilets can be expensive, they make up for the price in the long run. You can get back what you spent by saving money on water usage.

No raw sewage

This is a big plus for RV drivers and users. Cleaning an RV’s tank is not a pleasant experience and can be avoided by using one of these toilets. No more rolling up your sleeves, putting on a mask and gloves, and holding your breath for cleanup.

What are the drawbacks of composting toilets?


A new composting toilet can be quite an expensive buy, running into the thousands of dollars. It all depends on the brand and kind of composting toilet you end up choosing. There are a number of affordable options on the market, as well.

Health issue

If you do not approach and handle the matter of making compost correctly, you can get sick. You have to move the compost when the pathogens in your waste are no longer present.


A composting toilet requires a lot more maintenance than a normal toilet. You will have to be dedicated to doing things properly. Before getting a toilet of this kind, make sure that it is truly what you want. However, if you already have one, you can change your mind.

You can uninstall the toilet and put back the ‘normal’ toilet. Fortunately, you can interchange these products. It could be costly in the end if you go back and forth between toilets, though.


Unless done the right way, a composting toilet could give off a very bad smell. You will have to keep things clean and well-maintained to avoid unpleasant odors. However, it should be noted that most people think these toilets smell nicer than normal ones. The toilets that separate urine and poop are especially considered to be less smelly than flush toilets.

Some advocates of composting toilets have described the smell associated with it as the smell of a plant nursery. Thanks to the fans that composting toilets use, there won’t be any lingering odors in the air.


Most composting toilet systems need to be connected to a power source. Some users have reported simply using a sturdy battery. You should do proper research on this to be safe, though.


Again, if the composting toilet is not maintained properly, bugs and insects could infest it and make themselves at home.
