The Nature's Head Composting Toilet is the latest design, the best value, and the most reliable choice for portable, self contained, urine separating dry toilets -- on the water, on the land, or on the road." "This toilet or head, (the marine term for toilet) was designed by two long time sailors who sought to create a more user friendly version than anything else on the market. While we designed our product to withstand the harsh marine environment, it can be used anywhere you need a toilet, especially anywhere that plumbing or electricity is difficult or non-existent -- on RVs or campers, in vacation cabins, workshops, barns, yurts, even trucks. Most importantly, this toilet doesn't have the foul odors associated with all other holding tank systems. The low volume air circulation fan built into the head provides the added benefit of recycling the air in your bathroom which helps make your whole environment smell better. Because it was originally designed for marine use, its rugged design and materials (all stainless hardware) it has been proven to be extremely durable no matter what your environment.

I also wanted to take a moment to talk up the company. We had a question on our install so I emailed the company. Got a response in 20 minutes and my wife spent 30-45 minutes on the phone with them on a saturday. Just a good old awesome company to work with.
Problems: overflow of urine container, a mess. Time to empty solids, very tricky. User ended up scooping it out with a trowel, another mess. Then our 34 year old son was staying in the house during Christmas. More problems: urine diversion not working properly even though he followed directions. Solids container getting too wet with urine because the design for urine collection not able to handle a strong stream and quantity. Smelly, with so much urine mixed into solids. So he and I took it apart to empty into compost bin. Glad he is a strong guy with tons of muscle! I could never do it on my own, even though I am strong and outdoorsy. That experience clinched it for me, made me realize just how simple my old bucket system is.
The above review was written by my wife who is a very experienced composter. If you have to compost in the toilet, Nature's Head may be your best choice, but there are challenges which were not made clear. First, it may not easy to see how full the urine container is. Second, the instructions to be careful not to allow urine into the main chamber may be impossible for some users with strong flow. Finally, since the entire base is the main chamber, it can be a bear to move.
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).
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.
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.
