Nature’s Head Composting Toilet Review

Check out how the Nature’s Head composting toilet performs in our detailed review. It’s cheaper than its competitors, but does it deliver on performance?

Nature’s Head is a company with a wealth of composting toilet know-how and experience. They started off many years ago manufacturing toilets for marine use. This means they are well aware how to make a toilet unit fit and function in a confined space. As they are an experienced company they also offer an awesome full 5 year warranty on these toilets. Being an American based company, they also offer really good customer support. This makes the transition from flush toilet to composting toilet that much easier.

These composting toilets are also among the least expensive on the market. That’s not to say that they’re cheap, but they retail at a lot less than some of their competitors. These Nature’s Head models aren’t flashy, but they are really functional and dependable.

Nature’s head offer two similar composting toilet models. The only difference is the way in which the agitator handle is used. The agitator handle is a handle which extends out of the side of the toilet unit. It is manually used to mix the content of the solids waste bin after each deposit.

Crank handle (left) & spider handle versions

The two choices are a spider handle and a crank handle. The spider handle is a neat, space saving design, inspired by marine life. The handle doesn’t extend far out of the side of the unit so it really narrows the unit size. It means the spider handle version of the composting toilet is actually 2.75 inches narrower than the crank handle version. The crank handle model is wider, but in my opinion the crank handle is slightly more user friendly. Turning the handle in this motion is a bit easier and faster.

The two models retail at exactly the same price and have exactly the same features. Your only choice is between saving some space on the sides or which turning motion you think is easiest.

The toilet is sturdily designed. It has a robust polyethylene construction with stainless steel fittings. It is very compact, but remains completely functional too. The bins are quickly and easily removed and emptied.

Performance

These composting toilets are water-free, odor-free, and electricity-free. They use a two waste bin system. One bin is for the solid waste, and the other for liquid waste. The two different types of waste are diverted into their bins using a flush handle on the side of the unit.

The solids bin (or composting bin) is said to last for about 90 uses before it needs emptied. This is quite a conservative estimate and customers have been known to have their compost bins last much longer.

To form the compost, peat moss must be added at the start. Around two gallons of peat moss should be sufficient. Sphagnum peat moss is easily purchased from stores like Home Depot and Lowe’s and a $10 bag should last about a year.

After each addition to the solids bin, the agitator handle must be turned a few times. This is to mix the composting bin and help the compost form.

The liquid container must be emptied much more frequently. It is easily unclipped and has a handle at the top to make carrying it really easy.

The unit ships with 5 feet of ventilation shaft and an electric fan. The shaft should be connected to the outside of the building. The electric fan might not be necessary if the ventilation shaft is short and doesn’t have bends in it. It will only draw a very small amount of power. Around 1.7 amps over 24 hours.

Installation

A helpful feature of these Nature’s Head composting toilets is that the handle and ventilation shaft can be mounted on either side of the unit. This gives more options at installation.

The unit ships with everything you need to install it except the outside vent. As this would be different in every situation it would make no sense to include it. The package includes these things:

  • Liquids bottle with cap
  • Inside vent flange
  • Agitator handle
  • Allen wrench to install handle
  • 2 mounting brackets with screws and knobs
  • 18″ single pin cable for 12 volt fan installation
  • Fuse and fuse holder for 12 volt application
  • 5 feet of 1 ½ inch hose

Installation requires absolutely no plumbing and isn’t a complicated task. You need to bolt the toilet to the floor, and then form the ventilation route. Remember you are going to need to leave plenty of space at one side of the toilet for the handle to be turned easily too. You will also need to leave a couple of inches behind the unit to allow for the tilting of its top when removing the solids bin

The fan will run on 12V power but can be changed with transformer/adapter to run on 110V power.

The spider handle model has dimensions:

  • Height: 21.5 inches
  • Width: 18 inches
  • Length: 17.75 inches
  • Weight: 28 lbs.

The crank handle version is 2.75 inches wider, but identical in size in all other ways. These dimensions are some of the most compact for a compost toilet that we have seen. This means that it’s great for tiny spaces, but doesn’t have the capacity of some others. It really depends what you’re looking for
