  • The Natures Head Composting Toilet is completely organic in that it has no smelly or hazardous chemicals. The only thing you have to add to our toilet is peat moss. The peat moss actually works to break down the solid wastes and turn them into fertilizer or compost.
  • Because our toilet separates the liquids from the solids (to put it politely), it doesn''t smell bad. It’s when you mix the urine and the solids that you get the really bad odors associated with sewage. When working properly the toilet will have a slight earthy smell when you open it.
  • Because the liquids are not mixed with the solid wastes you get an exceptional amount of uses before you need to empty the unit. For example; a couple using their boat or cabin on the weekends may go an entire summer without having to empty the solid’s tank. The front liquid tank is approximately 2.2 gallons and will need to be emptied more frequently. We empty ours into the marina toilet.
  • The Natures Head Composting Toilet is called a dry toilet because it uses no water for flushing. That’s right; there is no plumbing to attach to our toilet. This is yet another reason for the exceptional capacity.
  • Un-like any other type of toilet, the longer you let a composting toilet sit, the better it will smell when it’s time to empty it. No more having to deal with pump-outs or smelly portable-potties at the end of your long weekend. The longer a composting toilet sits the more time it has to do its job.
  • Our toilet is very economical to operate; there are NO chemicals to buy. We purchased a bale of peat moss from “Lowe’s” more than two years ago for $10.00 and we’re still using it.
  • Easy to install; the unit attaches to the floor with two small l brackets. There is one ventilation hose to run outside and one 12volt power hook-up for a small computer type fan. The unit could even be run completely powerless by running the vent hose to a solar vent. (Please see or installation instructions for additional information)
  • Easy to empty; when it’s time to empty your toilet simply flip the two latches on the sides and lift the upper section up a few inches. Put the lid on the liquid bottle and lift it out of its holder. To empty the main tank un-hook the 12 volt power connector and the vent hose and then slide the upper section off its open ended hinge. Undo the 2 thumb screws on the base and it’s ready to empty. Because there are no liquids in the main tank, even full it is never heavy. The unit is sized so that a kitchen garbage bag will go over the end of the main tank. Simply flip it over and you’re done. There is no need to clean the tank when you empty it, any left-over matter will help start the composting process all over again.

4.0 out of 5 stars Great product!, December 3, 2013

This review is from: Nature's Head Self Contained Composting Toilet with Close Quarters Spider Handle Design
Got this for a mobile "tiny house" project in an urban area, where a sawdust toilet wasn't practical (plus my boyfriend refused to poop in a bucket). The design on the composting toilet is nice, especially for those who might be intimidated at using a non-traditional toilet (read: Americans). For regular use plan to empty the urine jug about twice a week. I just cleaned the main compartment for the first time and it was easy: about as much work as cleaning a regular toilet. As for frequency, 2 adults over a 3-4 week period and it wasn't even close to "full" yet (though the crank was getting hard to turn). Absolutely no smell except that of soil. The urine jug smells when you empty it, but hey! It's a giant jug of pee so what do you expect? The only reason I'm giving it 4 instead of 5 stars is that it does seem expensive for what it is, but as a previous reviewer mentioned it might be a LOT cheaper than the alternative depending on your situation.

5.0 out of 5 stars Great Product. Well-built. No Smell., December 23, 2013

The toilet works great, is built very solidly and works as described. No complaints! More affordable and easier to install than just about any other composting toilet on the market.

2.0 out of 5 stars Over priced for what you get, June 12, 2014
This review is from: Nature's Head Self Contained Composting Toilet with Close Quarters Spider Handle Design
I have been using this toilet for over 4 months full time in a RV and it's time for the review. I would give this toilet more stars if it were priced at about $300-400 which is what I feel it's worth. This toilet has way to many flaws to be at its current price.

This toilet uses no water so if you are dry camping in a RV you can extend your stay several days without having to fill your fresh water tank or find a sewage dump site.
The steel and the plastic used is functional (except for the urine reservoir, see cons).

It's ugly.

The vent hose included is is only 5ft which is too short to vent the toilet to the roof of most RV's or a standard home. You can buy a longer one by the foot but it's not cheap. In fact all their accessories are over priced. The hose can easily be cut so the manufacturer should really not be so cheap and include at least 8ft of vent hose.

The vent fan included has so little power that if another larger fan such as the bathroom ceiling fan is in use it will actually suck air from the toilet's exhaust hose back into the RV bringing odors into the bathroom. Opening another roof vent or window in the RV before turning on the ceiling fan will help prevent this from happening.

No external vent or back-draft stop is included. For the over priced toilet I feel like a marine vent, a house vent and a RV vent should all be included. I ended up using 1 1/4 inch PVC pipe with a 90 degree elbow and a screen cut and glued to one end of the elbow. The vent hole is cut on the floor near my water heater where it is out of sight. The elbow will need to be able to turn to face away from wind gusts. If you live a windy area the wind will push smells back through the exhaust hose back into the bathroom.

The toilet does not smell like sewage. It does however smell funky. I wouldn't call it a soil smell, maybe earthy. It smells more like a combination of a rotting tree log and a swamp. It doesn't make me gag when I empty it so it's not a bad smell but it isn't odorless and doesn't smell like soil.

To empty the urine you must lift the seat releasing the funky smell into your bathroom. It's a terrible design.

The seal between the seat and the composting bin is not a suitable material for its use. After only a few months mine has stretched and it has started to slip out of its position so it no longer makes a perfect seal.

The urine catch in the bowl is too shallow. The solids flap has to be closed when you have to urinate really bad. A high pressure urine flow will easily flow over the urine catch and spill onto the solids flap, it then gets diverted back to the urine reservoir if the flap is closed. This makes it hard when I need to urinate and poop at the same time since I don't want the urine to spill over into the solids area.

The urine reservoir is hard to see through unless you have the toilet in a extremely bright room with sun light hitting it. It has no LED light to illuminate the liquids, no sensor, no mechanical gauge, no nothing that would help determine when it should be emptied. I have been using a LED flashlight up against the reservoir to illuminate the urine when I check the level. After my one overflow experience I plan to install a permanent LED by drilling a small hole in the plastic that holds the reservoir. After months of use the urine reservoir will darken to a rusty tint even when using vinegar and rinsing it after every dump.

When the urine reservoir overflows it makes a huge mess. This has happened to me once (I blame the beer). The urine overflows into the solids composting area and makes a stinky soupy sewage mess. Then when you lift the seat to empty the urine reservoir about a cup of urine spills out from the spout that fits into the reservoir. Maybe 50% of the excess urine makes it into the plastic that holds the reservoir the rest spills out on the floor. The seat at this point will have urine on the inside of the seat area where you can't see it which will drip all over the place if you detach the seat. In a overflow situation I recommend you take the whole toilet outside or at least put in in the bath tub very carefully before you start the and cleanup process.

Other comments:

For me a 210 lbs. male using this full time the urine will need to be emptied every 2-4 days and the solids will need to be emptied every 3 weeks. If I squirt the toilet paper with a water bottle before turning the spider handle I can sometimes get 4 weeks of use before I have to empty the solids.

When pooping you must sit up very straight. If you lean forward at all you will be wiping skid marks off the back of the bowl.

Peat moss in my experience is not a good choice for this toilet. It is heavy, bulky and worst of all it will hatch fungus gnats. Coco coir is the best since it is lighter when dry and contains no bug eggs. Coco can be found in large dry compressed blocks at your local grow/hydroponic stores or on Amazon. It usually isn't available at the bigger department stores.

Every RV and boat should have one! I'm seriously thinking of installing one in my home! Very well designed and made.

5.0 out of 5 stars seriously awesome, June 25, 2014
This review is from: Nature's Head Self Contained Composting Toilet with Close Quarters Spider Handle Design
awesome, awesome, awesome, AWESOME!! this is a far cry from pooping in a bucket. super easy to use, my three year old figured it out immediately. there is no smell, either, amazingly enough. okay, there's some smell, but it's more like potting soil than poop. as a matter of fact, we inadvertantly shut off the vent fan and smelled a strange, dirt-like odor. it took us a minute to figure out it was the toilett! the best part is: you can use whatever toilett paper you choose. just keep in mind that the super-absorbancy stuff is no joke. when the crank gets too hard to turn, just add a cupfull of water and it will loosen right up. we have gone two weeks before filling the tank. the pee tank is another matter entirely. it is huge, but with two adults and one child, we have to empty the tank every morning, and that's the stinkiest part of the whole process. but it's pee ... it stinks. definitely a good buy for anyone looking to live off grid, or for anyone that's sick of flushing two gallons of water with every flush, or smelling the sewage from their rv, black-water tank. also fits in an rv (ours is 30') bathroom. if you're planning on using it as your everyday toilett, plan on buying a second bin. it has to compost for at least a week before dumping, so do the math.

5.0 out of 5 stars Got one for my boat but great in an office cubicle as well, November 30, 2012
This review is from: Nature's Head Self Contained Composting Toilet with Close Quarters Spider Handle Design
I got one of these for my 45 foot sail boat or yacht as the technical term would be. I was going to have to replace tanks, hoses, thru hulls and the 40 year old toilet so price wise this cost less to install. And the cool thing is that it makes dirt from poop, which on a boat can be very useful for growing things like tomatoes and those maple tree plants that are so popular with the South Pacific sailing community. Fresh Syrup for your pancakes is like gold on a taco shell or some other euphemism I cant think of. Then I thought this would be great in my office cubicle, with this and a fully loaded sandwich vending machine and some ice cubes and a britta fiter for the pee recycling. Id never have to leave my office. And with the dirt I could put on my floor and grow some inside grass(or mushrooms which are better cause I dont get any light in our building) to keep the appearance of a circle of life going. F'n Amazing machine. I'm getting two more just to carry around with me.
