Nature’s Head ®
The Nature’s Head ® composting toilet is an innovative, compact design ideal for cottages, boats or RVs. It eliminates the costly, complex, space-consuming and inconvenient holding tank and septic systems. The Nature’s Head ® composting toilet is affordable, easy to install and simple to operate. It holds 60-80 solid ‘uses’, which means two people could go 6 weeks without emptying it. It produces organic compost – not raw sewage
The key to the success of the Nature’s Head composting toilet is the urine separating design. The liquids and solids flow into separate chambers. You can see in the photo on the right there are two drain tubes in the bowl of the Nature’s Head that should capture most of the urine. The solids drop down when you open the trap door (shown closed here). The urine collects in a removable bottle.
Composting toilets have been slow to catch on, because of problems with odor. This has largely resulted from too much liquid mixed with solids. With too much moisture you don’t get compost – you get a stinking mass of raw sewage! By separating the urine from the solids the Nature’s Head composting toilets solve this problem – resulting in odor free, trouble free composting.
The Nature’s Head composting toilet is well made of heavy duty, roto-molded plastic and stainless hardware. It is not flimsy, like a port-potti. I can’t think of any way this toilet could break under normal use. The focus is on durability, simplicity and reliability.

Here are some of the features of the Nature’s Head Composting toilet:
- Proudly made in the USA! Fair wages are paid. Strict environmental regulations are adhered to. Children are not employed.
- Five Year Warranty.
- Completely self contained and portable.
- All stainless hardware.
- Full size elongated seat for comfort.
- Disassembles in seconds for emptying.
- Composting handle can be mounted on either side.
- Vent hose and fan may be mounted on either side.
- Unit comes with everything for your installation except the external vent.
- Molded in toilet seat for safety and ease of cleaning.
- Fully supported liquid tank for applications where it extends beyond mounting pedestal.
- Translucent 2.2 gallon liquid tank allows for easy visual capacity inspection.
- Rear of main tank is angled for hull-side installation on boats.
- It’s AFFORDABLE!
The electric receptacle for the 12 volt or AC adapter is conveniently located on the top right of the fan housing. There is minimal current draw. It is rated at 0.07 amps, which is under 1 watt at 12 volts. Over 24 hours you will use 1.7 amp hours of your battery capacity. Power-free installation of the Nature’s Head composting toilet is possible with the optional solar vent.The vent hose is attached to the fan side. A wall adapter is available should you want to plug it in to a regular household type receptacle.
Here are the Nature’s Head composting toilet dimensions. You need an additional 2″ front to back, to allow for tilting the toilet top to remove the urine bottle (19.75″ needed, front to back).
Note there are two handles that you can choose from – the crank handle, and the spider handle, which saves 3″ of space.
Getting ready to use the Nature’s Head composting toilet
Before using the Nature’s Head, and after each time you empty it, you need to put some coconut fiber or peat moss in the lower chamber, to help with composting. Below is an excellent video that explains how to do this.
When it is time to empty the solids bin, you open it up and place a compostable garbage bag over it. Turn the bin upside down and dump the contents into the garbage bag. The entire process just takes a few minutes. The garbage bag can then be placed somewhere else to finish composting.
Let it sit for about 12 weeks and you have finished compost. The finished compost can be placed on ornamental plants. Just to be 100% safe, you never put human compost on vegetables. A slightly more convenient solution is to buy a second bottom chamber. The bottom chamber is then just exchanged when full.
Urine is almost sterile and does not pose a health risk. Still, you need to be careful where you dump it. Boaters and RVers can simply pour it in a regular toilet, outhouse or anywhere it is legal to take a pee. If the Nature’s Head is installed at a cottage, you could build a simple French drain. This is a small pit, filled with gravel, then covered with landscape cloth, soil and finally grass. A vertical plastic tube should be placed in the middle of the drain so you can pour the urine from the top down into the gravel. Some owners use a flexible plastic tube that runs right from the toilet into a French drain beside the cottage, so they never need to empty the urine container at all.
There is a small 12 volt fan built into the Nature’s Head to ensure continuous air movement. It runs on a miniscule .08 of an amp, but you need a power source. A 12 volt battery works well for boaters or RV owners. A solar vent can be purchased as an option, which means it will run without outside power (nice!). Cottage owners can order a wall adapter, then plug it straight into any wall outlet. The vent exhausts outside.
Things to consider…
The small size of the Nature’s Head means it will probably not work for more than 2 people full time.The simplicity of the design requires a bit more involvement from the user than some of the larger, more expensive composting toilets. However, this simplicity is also a positive, since there are no mechanical raking systems or heaters to require maintenance or break down. The only thing that could possibly fail with the Nature’s Head is the fan, and that is a standard computer fan that can be replaced for a few dollars. This toilet should basically last forever.
Composting waste from the Nature’s Head
When you empty the Nature’s Head, you will have partially composted material that must be further composted outside (or as a last resort, thrown away). You can see my post on composting here, and read about the best composting tumblers here.
The Nature’s Head is a well-made unit that does what it is supposed to do. It is one of the least expensive composting toilets on the market at $960 including shipping (lower 48 states only, call for other locations), and will fit in very small spaces. There is a 30 day money back guarantee, (buyer pays shipping, however) and a 5 year warranty. Should you need to return the Nature’s Head, there is no “restocking fee” as there is with most composting toilets. It ships from Ohio by UPS, usually the next day.

Thanks again for being so prompt, skilled, and courteous in handling this order, Richard. Our society certainly would benefit from more folks like you. Much appreciated!
I love it!! Thank you for coming up with this design for the Nature’s Head. My husband and I have crawled all over the web looking for something just like this and it’s actually affordable (when compared to toilets made by SunMar and similar companies). It frees up space where the black water tank would go.
Hi, just a short note to tell you how easy it was to install our Nature’s Head. I bought two units and put one in while a cruising neighbor watched. He actually talked me into selling him one of my units and installed it in his boat. They work great! I’ll reorder a second one in a bit, I’m redoing my 12 volt system as part of a refit before taking a 3 year extended cruise around the world. I’ll continue to spread the word.

The Nature’s Head has worked great! I have a 30′ Pearson sailboat. The holding tank was way too small and took up room in what would have been a wet locker. It always smelled. It is illegal to pump over board and the pump out stations were not functioning most of the time . With four people on a 3 day weekend the holding tank would soon be overflowing. I looked at replacing the holding tank for a larger size but that reduced space further. I then started looking at composting toilets. The short answer is the first season in Maine the toilet worked like a charm. It doesn’t smell. It was simple to install and I was able to use the composting portion for the whole season with about every weekend use and a week family vacation with at one weekend 7 people on board! Urine disposal is quick and easy. It fits great in a cloth grocery bag and you simply dump it at the marina toilet. The only addition I am going to make is add an extra urine tank as we moor at islands that do not have marinas. The product works like a charm and I don’t have to worry about what my kids are swimming in.

It's a well made toilet, but a little pricey. We had a bad fan, and Richard sent us two replacements by courier the next day! I wanted to hook up a urine drain instead of using the bottle, and he told us how to do that. Three months in, and it's working fine. Great customer service. He actually answers the phone.
We researched this subject for months before purchasing the Nature's Head Composting toilet. We are a semi-grid tiny house located in Oklahoma. We have had it for two weeks now, using exclusively.
1. No smell. None. We are utilizing the vinegar recommendation in the bottle.
2. Fits in the same space as a conventional toilet.
3. Portable. We move the house, it goes with us, without a septic tank or field.
4. Attractive and easy to clean. Resembles a conventional toilet.
5. The seller is extremely nice and easy to work with. Made the whole process easy.
6. Very simple installation. We are using the 110 transformer, which is readily available from the seller, for half the cost of other sites we looked at.
1. You have to invert the whole toilet to dump the solids chamber. Seems like it would be better to have a removable chamber, just as you have a removable liquid collection bottle, and not have to remove the head from the floor to empty.
2. We agree with the general consensus that we have read, that for a molded piece of plastic, and relatively simple design, it is over priced. That is not to say the seller over charged, but the manufacturer who supplies the product.
Over all, we are happy with our purchase. We will be purchasing a second chamber when we can, because of the need to complete the composting process.
This is so easy to use. There are two of us using it full time and we empty about every 3 weeks. It takes 5 minutes to empty and there is NO smell. It seems well made.
This is a heavy duty toilet that works as advertised. Well made, well designed.
