Nature’s Head Composting Toilet – Spider Handle Design

Nature’s Head Composting Toilet is the best portable toilet to travel with. These toilets are called composting toilets for the fact that they biologically compost human waste and human waste decomposes into compost-like material as a result of this process. These toilets are specially designed for travel purposes. You can carry them along on road trips, camping trips, or RV car camping trips.

Nature’s Head Composting toilet is one of the best-reviewed ones. When it comes to the type of this head composting toilet, people are often interested to know “Does Nature’s Head composting toilet need electricity?”. Well, here’s the answer. No. Nature’s Head Composting Toilet needs no electricity or water for its functioning. And the best part, it stays completely odorless even then.

This toilet is equipped with everything you need to run it on 12 volts. However, the wall transformer must be plugged into an outlet in order to use 110-volt house power to power the fan. When there is no floor or wall in the cabin, the PVC vent can be used.

How to Empty Nature’s Head Composting Toilet?

Nature’s Head Composting Toilet contains two different chambers: one for the liquid waste and the other for the solid waste. Liquid waste is required to be cleared out more often after about 3 to 4 days. While the solid waste should be removed every 2 to 3 weeks. In this section, we’ll help you know how to empty the liquid as well as the solid chamber of the toilet.

How to Empty Nature’s Head Composting Toilet

Liquid Removal

Liquid waste containers of Nature’s Head Composting Toilets must be emptied as follows:

  1. First of all, the locks that secure the bowl to the base should be released by removing the latches on both sides of the unit.
  2. The next step is to install the cap and take out the bottle after raising the bowl to approximately 45 degrees.
  3. Dispose of the contents in an environment-friendly manner. Urine bottles can be emptied into toilets or other convenient facilities.
  4. In addition to emptying the liquid tank frequently, the tank should be rinsed with detergent and vinegar added. If urine is left in a storage container for an extended period, it will produce an unpleasant odor.

Solid Removal

The removal of solid waste requires more effort than liquid waste. That’s because you’ll have to unclip the toilet from its base. For emptying the solid chamber of the Nature’s Head Composting Toilet, do as follow:

  1. Once you’ve removed the bottle assembly, now you’ll have to remove the seat unit to reach out to the base of the toilet. Lift the seat up and slide left to separate it from the slip hinge.
  2. If it is necessary to move the bowl, the vent hose and power supply may need to be disconnected. You can now empty the base by removing the knobs attached to the mounting bracket on either side.
  3. The simplest way to empty the bag is to place it over the opening of the base and wrap it tightly around the rim. This will allow you to invert the bag and empty the contents without spilling anything. When using the toilet on boats or other mobile units, this is especially helpful because it is not necessary to remove the toilet.
  4. As composting will be carried out by the residual matter clinging to the sides of the solid waste container, it is not very necessary to clean the interior. This is because it is possible to disrupt the production of good bacteria that breaks down solid wastes if you clean the base unit with any chemicals.
  5. Hence, you only need to empty, add sphagnum peat moss, and then reassemble the toilet.

1. Design

nature’s head composting toilet - Design

This Spider handle design toilet is designed to withstand heavy usage. Built from polyethylene with stainless steel fittings, it has a robust construction. Although compact, it remains incredibly useful for a long time. Moreover, because of its incredible design, removing and emptying the bins is pretty simple.

Because of its self-contained design, urine-diverting feature, and waterless operation, the toilet can be used for a variety of applications. Nature’s Head dry toilets are lightweight, odorless, and compact, making them the perfect choice for cabins, tiny houses, RVs, workshops, boats, and traveling purposes.

2. Flushing System

Composting Toilets do not have flushing systems. That’s the reason they’re called ‘dry toilets’ and decompose the waste into compost-like material. Unlike flush toilets, composting toilets do not require connections to septic tanks or sewer systems.

In the same way, like other composting toilets, Nature’s Head Composting toilet also incorporates a carbon additive such as sawdust, coconut coir, or peat moss after every use. No water is required for flushing the waste. However, composting toilets can handle water used for anal cleansing without any problems.

3. Cleaning and Maintenance

The NH is easily kept fresh with a spray of water and white vinegar or one of the natural cleaners provided in the squirt bottle. Also, paper towels moistened with water are perfect for both inside and outside of the head toilet’s cleaning.

If very intense cleaning is required or there is dried-on matter, use a paper towel moistened with vinegar and water in a 1:1 ratio, and after cleaning, dispose of the paper towel. Composting heads should never be treated with bleach, ammonia, or other cleaning products because these additives inhibit the composting process and may cause unpleasant odors. Exterior surfaces may be cleaned with these cleaners.

This Nature Head’s toilet requires very little maintenance, which is the BEST thing about this toilet. Metal parts, including bolts, hinges, latches, knobs, agitators, and trapdoor components, are all made of stainless steel or brass, and they won’t corrode if taken care of.

Every year or whenever the solid waste is emptied, the filters on either side of the base should be cleaned. The filter units are connected to the housing using two Phillips-head bolts, they should be removed, cleaned, and replaced. The fan should be reinstalled in a correct way (when needed), so that airflow exits the unit when the unit is reassembled.

4. Performance

The Nature Head’s Composting Toilet performs great without spreading any odors. In order to avoid accumulating odors, it is recommended to empty the solids bin or composting bin after 90 uses. The estimate is quite conservative, and customers have experienced compost containers lasting much longer than the estimate.

The compost must be made with peat moss from the beginning. Approximately two gallons should be sufficient. Remember, it is necessary to turn the agitator handle a few times after every addition to the solids bin. This will help the compost mix and form.

6. Features

  1. Anatomically designed to fit human body shapes, the lid fits well over the comfortable molded seat. Maintaining the hygienic and clean condition of your Nature’s Head toilet is now easier than ever!
  2. Because Nature’s Head was created with boat installation in mind, each unit has an angled rear base that can be installed against a hull if needed. Having said that, it does not affect its use in a Tiny Home or recreational vehicle.
  3. Located on the side of the bowl, a small extrusion houses both the fan and air filter. In spite of the fan’s 24/7 operation, it consumes less than 2 amps per hour of 12-volt power in one day. The fan can be replaced as part of the warranty in case of failure.
  4. There is enough volume in the Nature’s Head’s base for two people to use it for around four weeks before emptying it. So long as you don’t swamp it with tissues, you can use it for several weeks without having to empty it. Then simply reassemble, replace the peat moss or coir, and you’re ready to go. In the case of emptying solid waste, it doesn’t require cleaning afterward.
  5. Installation is pretty simple. The two “L” brackets provided should be mounted to the floor, the toilet mounted with the two retaining screws, the venting hose, and power supply attached, then the peat moss or coir added. A small hole in the floor, ceiling, or wall can be used to mount the flange supplied for venting.

Nature’s Head Composting Toilet Installation Guide

Nature’s Head Composting Toilet Installation Guide

For the installation guide of Nature’s Head Composting Toilet, here are some important things you should know that would help you with the installation process.

Almost all of the items necessary for your installation are included with your NATURE’S HEAD composting toilet. As each application differs, there will be a need for a different outside vent.

  • Depending on the installation, an increased hose length may need to be purchased per foot. Longer sections of hose may also be made out of PVC pipe, available at most hardware or home improvement stores.
  • Different types of bolts may be needed for floors other than wood. It may be more convenient to mount the toilet to plywood rather than drill into masonry when installing it in a basement or another concrete floor. To give the plywood an attractive appearance, it can be painted or varnished and placed on the concrete floor.
  • A transformer or wall adapter fitted with a 12-volt output can be used if a regular household current (110 volts) is available. The Nature’s Head store carries them.
  • It will be necessary to use composting material. Usually, sphagnum peat moss (organic) is used, which you can find at most garden supplies stores as well as home improvement centers. This recycled material is usually available for $8 to $10 per shrink-wrapped 3ft cubic bale. The head can be used for a year or more with this quantity of sphagnum peat moss without any worries. Remember, no additives should be used in sphagnum peat moss. MIRACLE-GRO peat moss contains plant food and should NOT be used.
  • Coir brick (also known as coconut fiber) is another acceptable compostable material. The problem is that it is expensive and not widely available. However, hydroponic gardening outlets may sell it.

How Does Nature’s Head Work?

How Does Nature’s Head Work

Nature’s Head segregates liquid waste from solid waste using two chambers. Solid waste goes into the back container of the unit, while liquid waste is disposed of in a container on the front.

Liquid Waste

When the latch is closed, liquids drain automatically into the correct chamber. You just have to make sure that you use the toilet while sitting. DO NOT pee while standing as this might send the waste into the wrong chamber.

Solid Waste

In order to break down the organic matter you’re adding to this chamber, you first fill it halfway with a composting material, usually peat moss or coco coir.

Once you’re finished using the toilet, you can wipe it up. Putting the toilet paper in the solid waste chamber or in a separate garbage bag is fine, but make sure to spin the left-hand handle of the agitator spider a few times to mix it all up. More waste breaks down as it remains in the mixture for a longer period of time. The minimum is eight hours, however.

How much space do you need for a Nature’s Head toilet?

If you decide to install a Nature’s Head composting toilet in a suitable spot, make sure that there will be enough room. Make sure that you are able to fully open the lid of the toilet. Furthermore, the toilet’s back must be at least 4cm away from the wall or boat side.
