Best Composting Toilet Reviews 2017 – The Most Environment Friendly Toilets

More and more families are adding best composting toilet in their bathrooms. This type of toilet takes the waste that usually goes to the sewer system into a composting tank, where it is stored to reproduce a recyclable material.

Composting toilets are ideal in homes located in rural areas where water supply is insufficient and unpredictable. It also works well in small pontoon boats, RVs, and off-the-grid cabins, among others.

Best Composting Toilets - Comparison

How does it work?

Composting toilets rely on the natural process of waste decomposition and evaporation in recycling human waste. The waste that goes through the toilet is more than 90 percent water.

When this is evaporated, it is carried back to the atmosphere via a vent system. The remaining solid material is then converted to fertilizer by natural decomposition.

Installation

Composting toilet units aren’t difficult to install, even for a handyman. Most of the composting toilets available on the market can be secured by attaching two brackets to the floor.

An extraction fan or heater is then connected to an electric supply. Most toilets also have a pipe to vent odor, necessitating the drilling of a hole to route the pipe to the open air.

Types of Composting Toilet

There are basically two types of composting toilet--- self contained and central.

The self contained toilet has the toilet and composting tank built together as a singular unit. It is more mobile, easier to install, and requires less space compared to the central composting toilet.

But maintenance is more demanding than the central composting toilet. On the other hand, a central composting toilet has the toilet separate from the composting tank.

It is better at odor control, and requires less maintenance. But it isn’t as mobile as the self contained toilet aside from requiring more space for installation.

Benefits Of Using Composting Toilet

There are many reasons why people are turning to composting toilet, such as;

1. Reduced water usage— a lot of water is reduced because there’s no need for water in flushing down waste in a composting toilet

2. Independent household sewage--- composting toilets are great for situations when a septic tank is not possible or too expensive to build, such as in remote locations and rural areas

3. Location flexibility—composting toilets are used in RVs, small boats, and off-the-grind cabins.

4. It has a low power consumption.

5. It is environment friendly --as composting human waste and burying it can serve as fertilizer

Best Composting Toilets Reviews

Here are six composting toilets which you may want to add in your home or RV, check individual composting toilet reviews below:

1. Nature's Head Composting Toilet

Nature Head Self Contained Composting Toilet.JPG

This Nature's Head Self Contained composting toilet is equipped with a low volume air circulation built into the head.

It helps in recycling the air in the bathroom and make the entire environment smell a lot better.

It is originally designed for marine use, as shown by its extremely rugged design and all-stainless steel material. It is thus durable and should last for a long time no matter where you install it.

Nature's Head Composting Toilet is ideal for use in camping sites, as you can extend your stay for several days without refilling your fresh water tank or finding a sewage dump site. It is made of all-stainless steel with some bits of plastic.

The vent fan can prevent odor from the waste to pervade the air and make the environment smelly. And it is easy to use that even children will have no troubles dumping their waste on it. Installation should be a breeze as well.

However, it doesn’t have the most eye catching design. The vent hose is a bit short to vent the toilet to the roof of a standard home and even most RVs. It also lacks an external vent of back-draft stop. It is also expensive.

2. Nature's Head Dry Composting Toilet

Nature's Head Dry Composting Toilet

Nature's Head Dry Composting Toilet is a self-contained toilet that is lightweight, odorless, and compact.

It is a good fit for your cabin, RV, tiny house, and small boat. It is made of stainless steel and comes with a hand crank agitator in the base for fast composting.

It is easy to install and user friendly. There’s a five-feet vent hose, bottle cap, and 12v power plug included in the package. Nature's Head Dry Composting Toilet has a urine separating mechanism; with liquid waste flowing into a chamber different from where solid materials.

The urine is collected in a removable bottle. This results to better odor control and waste composting.

There are lots of good things about this toilet. It is affordable and easy to install. It can hold up to 80 solid waste which means up to two people can use it for six weeks without emptying the tank. It disassembles quickly for emptying the tank.

But with its dimension, it is not ideal for families with 3 or more people. The fan could also break after a few months.

3. Sun-Mar Self-Contained Composting Toilet

Sun-Mar Compact Self-Contained Composting Toilet

Sun-Mar Compact self contained composting toilet is ideal for the use of a single person in a residential area, and up to four people during a weekend trip to the woods.

It is a compact toilet that is a bit higher than the traditional flushing toilet.

It has a small profile making it a smart choice for small bathrooms, RVs, and small boats. It runs on standard house current. It is equipped with Sun-Mar’s patented Bio-drum for fast and odorless decomposition of waste. The manufacturer backs it with three year limited warranty.

However, the compost starter fluid needed for cleaning it is very expensive. And the drum is too small for most families.

4. Envirolet MS10 Composting Toilet

Envirolet MS10 Waterless Self-Contained Composting Toilet

Envirolet MS10 Waterless is a composting toilet that is more appropriate for families. It can handle up to 8 people per day.

A key feature of this toilet is its patented six-way aeration and evaporation process that circulates a large volume of air at a high flow rate for superior odor control and waste reduction.

Envirolet backs this unit with a lifetime warranty on the external body and a five-year warranty on internal components. It is ideal for use in cottages, cabins, and even homes and offices.

I liked that it can handle up to eight people a day. It has dual fans working with a natural microbe action to control odor.

Unlike other best composting toilet units, it has two fans with aeration for improved waste reduction and recycling. It is also easy to clean/maintain. The sanitary bowl cover easily closes and opens for use.

However, the dual fan system can increase energy consumption/usage. It cannot be returned to the manufacturer in case of defects, too.

5. Sun-Mar Corp CCES-01601W SPACESAVER

Sun-Mar Corp CCES-01601W SPACESAVER

As the name suggests, this is a space-saving composting toilet.

Sun-Mar Corp CCES-01601W SPACESAVER has a width of 19 inches and a depth of 22 inches, so it should fit in a small corner or even a closet.

It is fitted with a turbo fan and the Bio-Drum which is also used in the Sun Mar Compact. We love the fact that it is durable and can last for many years. Installation is relatively quick, with most users able to do so in an hour.

It is so small that it won’t take up a lot of space in the bathroom or cabin. The manufacturer gives a five-year warranty on the fiberglass glass, and three years on other components.

It can save thousands of gallons of water on a yearly basis. It has a small stool that makes it easier even for small children to use it.

However, it is very expensive. Cleaning/maintenance can be a hassle as well.

6. Centrex 1000 Non-Electric Composting Toilet

Centrex 1000 Non-Electric Waterless Ultra Low Flush Central Composting Toilet System in Bone

Centrex 1000 is a composting toilet that is a good choice for households where electricity is unstable, as well as those who are in need of a composting toilet for light seasonal application.

It should be able to hold compost for the full season in light to medium seasonal use.

Centrex 1000 is a composting toilet features an access port secured by a latch. It also has a 3-chamber technology, including the patented Bio-Drum where compost is mixed and aerated, as well as evaporating chamber and finishing drawer.

A four-inch vent stuck, running vertically through the roof, helps in minimizing odor. It draws air upward and maintains a partial vacuum in the unit.

We love that it can handle up to 7 people who are on vacation. It is engineered for superior compost flow to include input doors and output doors. It comes in fully assembled.

But I wont recommend this toilet for residential/continuous use. You’ll have to buy a one-pint flush toilet for use in this unit.

Final Verdict

All of these are excellent composting toilets that you can add in your off-the-grid cabin, small house, RV, or small boats.

Wherever you may install any of these best composting toilets, you can be assured of a good quality toilet with good odor control and waste disposal. Moreover, you can help save Mother Earth as you don’t have to use water at all with these composting toilets.
