Nature’s Head Composting Toilet


  • Stainless Hardware
  • Easy Disassembly
  • Incl Vent Hose/Fan


  • Overflow

The Nature’s Head composting toilet is a best-seller for a variety of reasons. If you need to have a reliable unit for your portable needs or a self-contained model that will support your entire family, then this is the product to purchase today. It offers urine separation that works effectively whether you’re at home, on the road, or even on the water with your boat. It was designed by two sailors who were tired of using inferior products and wanted to give everyone what their vision of a restroom should be.

Before the invention of this design, using a composting feature was a headache. You would need to take several safety precautions whenever you would work with the waste because there was no way to break down the bacteria or parasites that could be living in it. Your best solution was to douse this waste in chemicals (like the blue stuff you see on airplanes) as a way to stay safe.

Now you can take the convenience of a washroom wherever you go thanks to this Nature’s Head design. It can withstand the harsh climates of coastal living, yet it is still user-friendly enough to tag along in a camper or RV. Place it in your cabin, treehouse, or workshop to have an easy place where you can go at any time.

This design does not have the foul odors that are associated with holding tank systems that are designed by other brands. It features a low-volume air circulation within the basin, built into the head, to provide air recycling in your bathroom or installation area to make the entire space feel like a standard household bathroom.

You will need to add peat moss to this product to maximize the benefits it can provide. If you only use it to manage waste, then the composting feature will not work as intended.

There can be issues at times with the vent clogging on this model when it has heavy use. When you try to use a standard toilet paper product with this Nature’s Head composting toilet, then this issue can arise as well. Even if you do experience odors, the smell is similar to what it smells like outside right after it rains (assuming you have peat moss in there), so it isn’t a terrible experience.

If you try to empty the bin by yourself into a bag, then you will encounter some challenges with this product. We recommend having a designated area on your property that can accept the solid waste materials whenever possible.

It does take some time to get used to using the Nature’s Head, but it is an effort worth making if you’re ready to start reducing your water usage or need a portable toilet for any reason. Click here to compare prices on Amazon and find the best deal on the Nature’s Head Composting Toilet.

  • Difficult to Empty

You will find that it comes with a 5-foot vent hose to use, a bottle cap, and a 12-volt power plug that allows you to take advantage of its many features.

It is easily one of the best user-friendly models that are available today. The entire toilet is self-contained, which means you’re never exposed to the waste until you are ready to dump to the compost into a bag, bin, or pile. It offers a 100% waterless operation that makes it suitable for a variety of installations. You can have it work for a tiny house, a cabin, a treehouse, or even use it in a variety of survival applications.

We love the fact that Nature’s Head uses stainless-steel hardware to create a durable product. The construction is remarkably robust, allowing you to take this unit almost anywhere when you need a portable place to go. It really can survive some of the harshest conditions that are in the world today.

If you want to receive the best possible results, then we highly recommend running the exhaust fan around-the-clock to prevent odor buildup. You can operate the system from a set of 12v batteries, from a solar panel, or your other preferred power source. Just remember to crank the agitator a couple of times per day to ensure that you get a good mix.

Emptying the container is not for the faint of heart, especially if the compost hasn’t fully formed or the exhaust fan hasn’t managed to remove all of the odors. It isn’t going to make you wobbly in the knees, but there is definitely a process that requires some adjustment when you need to service this model. You’ll need to empty the liquids about every three days if you are using this product full time.

There are a couple of concerns to think about with this model. If you use the hand-crank aggressively with this composting toilet, then you will increase the risk of it breaking on you. When that happens, your only option is to replace the assembly or manually turn the materials in the basin – not recommended. Some people may experience insect infestations if the base of the vent hose is not properly sealed as well.

If you are looking for a way to create a positive bathroom experience without the installation of a septic system or requirement to connect to a sewer line, then the Nature’s Head dry model will meet your needs quite effectively. Make the investment today, and you will begin to enjoy saving water every time you need to go. Click here to compare prices on Amazon and find the best deal on NH Dry Composting.

How to Find the Best Model for Me

When you start shopping for the best composting toilet, then the quality of its venting must become your top priority. There must be a significant quantity of air flowing over the compost you create to prevent odors from building within the basin.

Even the best models with high-quality seals will begin to produce smells if there is zero air movement over the waste being stored.

The top models in this category will also provide an automatic stirring mechanism that will help to keep the waste moving as another way to prevent odor buildup. It will also reduce the chances of unhealthy bacteria or parasite exposure because air continues to flow through the solid particle clumps as it turns. Manual options are available too, but it is worth the investment to get this automatic feature if you can afford it.

It is essential to remember that composting models are a little taller because of their storage basin, so the seat height can take a little getting used to.

Important Features to Look For

There are two critical elements that you cannot afford to compromise on when shopping for this product today.

1. It must be able to properly seal the basin to vent any fumes or noxious odors away from the room or space where you use this product.
2. There must be a high-quality stirring mechanism available for the product to ensure that the composting process works as it should.

You can potentially save a little money when shopping for the best composting toilets today by looking for a model that requires manual mixing. This design adds one more step to the maintenance process for this product, but it also removes the cost of the automatic mechanisms that do this work for you.

Prices for the Best Composting Toilets

Most models are priced between $750 to $1,500 today, depending on the size of the basin, the presence of automatic features, and the overall quality of the installation. Some models are priced above $2,000 when auto-venting comes with the product.

Benefits of Composting Toilets

It is an understandable comparison when people think that a composting toilet is similar to the outhouses of yesteryear. The mechanisms of going to the bathroom in both options are remarkably similar. Your liquid and solid wastes all go into a basin that requires servicing periodically to prevent unwanted odors from escaping.

Unlike plumbed-in flush toilets, the composting variety allows you to turn your waste is this something that is useful. You will need to use peat moss within the basin to encourage this biological process in a healthy way, but there are some other fibrous options that can help you turn what you expel into a fertilizer to use on your garden.

You will need to empty the basin 1-2 times per month to empty it. Some require bags, while others give you a bin to clean and maintain.

Another benefit to consider with this technology is that you can have a restroom which requires zero electricity. If you choose a model with a manual crank, then you can use the bathroom as you normally would. Even if the power goes out, you will still have a safe place for everyone in the family to use the restroom.

Composting toilets install in a variety of locations as well. You can place them in a treehouse, put them in your shop, or place it in a formal bathroom setting if you prefer. If you go completely water-free by using this technology, there is the potential of saving up to $250 per year when compared to the water use you would have with a standard flushing model.

FAQ About Using a Composting Toilet

Many people are curious about what the pros and cons of owning a composting toilet would be. Some might even think about using this option on their property in some way, like adding it to a treehouse, basement, or workshop that is away from the main home.

If you have always been curious, then here are some of the frequently asked questions that people often have for this product and the answers you can expect.

Does it smell?

No. Assuming that the seals which come with the product stay intact, you will not detect an odor from this product. If there is a disruption of the seals, then you would smell some odors just as you would detect sewer gas from a malfunctioning standard toilet.

How often does it require service?

If you have two people who are using a composting toilet every day, then you will need to manage the liquids about every 72 hours. The solid waste usually needs to be serviced about once per month. You won’t need to worry about insects or pests getting into the product because they can’t detect the odors either.

Can I use toilet paper?

Yes. The best toilet paper to use when you have this technology at home is a rapid-dissolving product. Look for options that work with portable toilets, RVs, and other camping models for the best possible results. Just remember that the more paper you use means faster changes are necessary for your composting bin.

Do I always need to sit down when I go?

Guys – you can stand up when using this toilet when you need to pee. It will still capture the liquids. It is just recommended that you sit down because that helps this technology do its job better, but it’s not mandatory.

What happens if I get sick?

Composting designs can handle vomit, diarrhea, and all of that other wonderful stuff that happens when you get sick. You won’t be dealing with chemicals, wasted water, or raw sewage if something happens either. The organic materials all go into the bin to become useful for composting later on.

Where can I place a composting toilet?

You can place them almost anywhere to create an instant bathroom. It is the perfect addition to a tiny house. You can add it to your boat, your RV, or even a camper van to eliminate the emergency pit stops that are sometimes necessary on a road trip. As long as you keep the fan going on this product, there are zero smells to worry about when using it.


Most of the work that you will need to do when installing is to incorporate the appropriate venting around the fixture. If you install this product outside, then this issue is no longer problematic.

If you decide to install a unit indoors, then you will need to run the vent piping through an existing hole in your exterior structure or create one yourself.

When this modification is necessary for your primary home, then a building permit is sometimes necessary because you’re making an adjustment to the exterior of the structure. If you install this product in a treehouse, cabin, or stand-alone shop, then the work you need to do for venting is usually covered in the overall permit.

This product must be placed on a surface that is firm and flat. Whenever there is a slight incline when using this technology, there is added stress placed on the seals of the basin. This issue may eventually cause enough premature wear-and-tear that it may fail before the end of your warranty period – without coverage for placement because the use would be considered a violation of the terms of the warranty.

Are You Ready to Buy Today?

A composting toilet can be a significant investment for many households. There is no getting around the cost of this technology. The bright spot is that when you are 100% waterless when going to the bathroom, there is an opportunity to save money every time you don’t need to flush.

Think of the best composting toilets as a traveling companion for your RV, camper, or truck. They are the perfect installation to consider when building a luxury treehouse or creating an effective working area in your garage, barn, or shed. Installation is fast, especially if you have access to a power source for the exhaust fan already in place.

Although you will need to service these units and that can be an unpleasant experience for some, this technology makes it easier to enjoy a genuine bathroom experience almost anywhere. Choose your preferred model today to begin enjoying the good life!
