The world we all live in is now starting to wake up to the need for environmental conservation. This implies we’re attempting to produce fewer carbon emissions and effectively manage our resources. Purchasing a composting toilet is one way to attain this. It consumes less energy and water, and others do not use any at all.

Originally, the finest composting toilets were mainly limited to RVs, small houses, houseboats, and vacation cottages. Nowadays, you may even see one in a typical modern home. First, however, you will need to modify your home’s plumbing to support it.

Read on as we give you reviews of the top 5 best composting toilets in 2021.

 

 

1. Porta Potti 92306 White Thetford Corp Toilet

 

 

This is our choice for the overall best composting toilet for a tiny house for the money.

This composting toilet is made up of two firmly attached sections that may be readily separated when needed. The top part of the container carries 4 gallons of fresh flushing water. Its bottom part holds its waste for up to 5.5 gallons.

A Porta Potti is a full-service toilet. It comes complete with a toilet paper holder, flusher, cistern, seat, and lid. Its lower portion is odor-sealed and also includes a branded odor neutralizer. When it’s ready for a water refill, its water-level indicator alerts you.

The Porta Potti may be securely emptied into a standard toilet. It does not require plastic liner sheets. However, after cleanup, add a little deodorizer to its waste tank to neutralize any odors that have dripped through its plastic. In addition, the toilet requires 6AA batteries, which might be a problem.

The batteries deplete quickly. When they die, the water inlet might leak and overflow. Moving the flusher knob anti-clockwise will increase the lifespan of your battery. It ends the circuit and disconnects the battery energy. And if you need to use it, turn the knob “on.”

 

Pros

  • Portable
  • Has ground lock-in option
  • Battery operated (one wat to conserve energy)

 

Cons

  • Build up of gas pressure

 

Overall review

Porta Potti is a fashionable alternative to traditional toilets. This composting toilet consumes less water and does not require electricity. However, it requires a neighboring septic system or sewer, and you must empty it daily.

 

 

 

 

2. Nature’s Head Self Contained Composting Toilet

 

 

This is our choice for the overall best composting toilet for a tiny house regardless of cost.

Nature’s Head composting toilet is a fantastic choice if you want an environmentally sustainable toilet manufactured in the United States. Because it is a waterless toilet, it helps to save natural resources. Because toilets normally consume 1-4 gallons of water every flush, installing Nature’s Head toilet can save up to 20 gallons each day.

Rather than flushing, move the toilet handles to combine your waste and hasten the composting. This toilet has either spider or crank handles. This kind of handling consumes more energy and takes up more space. Spider handles are preferable for restrooms with limited space.

The upper portion of the toilet has the feel and look of a ‘regular’ toilet. However, because it is composed of stainless steel, you won’t worry about corrosion. The granite-inspired metal makes cleaning the toilet very easy. In addition, its expanded seat makes using the toilet more pleasant.

Nature’s Head composting toilets include its unique vent, fan, and hose to keep undesirable odors away from the nose. You may use the hose to pump your waste through the septic tank or community sewer. It requires 12 volts so that you can pump out the wastes with batteries or an RV engine.

This Nature’s Head composting toilet contains a solid and liquid waste separator. Since it delays decomposition, separation allows you to go for extended periods before emptying. However, it would help if you made sure to turn on the solid and liquid disposal valves. It’s a simple task to overlook, and several users do.

 

Pros

  • Easy to clean
  • Includes vent, fan and hose to prevent odor
  • 5-year warranty

Cons

  • The urine container fills up fast
  • Expensive

 

Overall review

The drawback is that Nature’s head composting toilet requires sawdust or peat moss, which you should purchase separately. These items are not permitted to be disposed of in public sewage. As a result, you’ll need to find a secure area to discard your toilet waste. If you don’t do any gardening, you may give these free fertilizers to a neighbor who does.

 

 

 

 

3. STANSPORT Portable Camp Toilet

 

 

This is our choice for the best cheap composting toilet for a tiny house.

As you imagine a composting toilet, you assume it will decompose indoors. There are, however, alternative methods to save power and water. Stansport is an excellent example. It does not immediately break down your waste, but it helps protect your groundwater.

It provides a simple route to transfer waste rather than dumping it straight into landfills and sewers. Fit this lovely toilet onto your plumbing. You may also use it outside. It’s more convenient (and sanitary) than crouching in the woods. It’s also small, measuring roughly 1-cubic foot.

The Stansport Portable is especially suitable for road travel with small children. However, you could be concerned while you wait for the next stopover. Even if you can find one, you may be concerned that public restroom bacteria may infect you and your children. Use your own disinfected portable.

The commode in the shape of a bin can contain 350 lbs. of waste. You may use it with a lining bag from the Stansport store. When the bag is filled, dispose of it in a traditional toilet or a designated human waste disposal location. For example, you might dig a hole in the ground for solid trash while camping.

 

Pros

  • Convenient size
  • Convenient handles
  • Conserves electricity and water
  • Affordable

Cons

  • If you wish to compost your toilet waste, you must first re-treat it.

 

Overall review

This portable toilet is ideal for long drives and camping adventures. However, it lacks built-in composters, so that you will be dealing with raw waste. Thus, do not forget to use gloves and wash your hands with antibacterial soap.

 

 

 

 

4. Camco 41541 Travel Toilet

 

 

Separating liquids and solids is a crucial aspect of compost toilet innovation. However, there are various options for resolving the separation issue. The waste storage and flush tank are separated in this Camco toilet. They are joined by two strong locks that keep contamination away.

The locks prevent the toilet seat from slipping while being used. However, when it comes time to empty the waste tank with a 5.3-gallon capacity, its mechanism is simple to separate. Although this is not a dry toilet, it only requires a few ounces of water every flush. The portable cistern holds 2.5 liters of water.

This is nearly half the amount of water required to flush a standard toilet. You may also purchase Camco TST to aid in the safe decomposition of waste. It disinfects the toilet and partly treats waste as you dispose of it. In addition, TST is biodegradable, making it suitable for use in outdoor disposal and septic tanks.

It’s very easy to fill the toilet. Just below the toilet cover, there are two caps. To pour in the flush water, loosen one of the caps. To flush it, press the opposite ‘cap’ down. The bowl is comfortable, compact, toilet paper safe, and easily cleaned with a wet cloth.

A moving gate valve separates the top flush from its base waste tank. These valves are both resistant to water and odorless. In addition, the two parts of this toilet are firmly locked together after the locks are closed. As a result, you may raise the entire toilet without fear of a stinky mishap.

 

Pros

  • Lightweight
  • Strong handles
  • Made of strong plastic
  • Easy to clean
  • Affordable

Cons

  • Liquid and solid wastes are not collected separately.

 

Overall review

The major drawback is the time pressure. In addition, its tank isn’t quite as large as a standard composting toilet, and then you would have to dump it daily. Also, you cannot fit it over a regular sunk toilet because it contains a holding tank. It is, however, easier to maintain than most other portables.

 

 

 

 

5. Sun-Mar GTG Composting Toilet

 

 

Composting toilets commonly come in uncomplicated designs or basic styles. Sun-Mar GTG violates this rule. It features a conical base and D-shaped seat, both of which are in line with European tastes. This makes it an excellent option to add elegance to your isolated house. In addition, this toilet is simple to install.

Despite its attractive appearance, it is a simple, not fancy dry toilet. Although there are distinct chambers for solid and liquid waste, there are no cranks or systems to move your solid waste. That is, it does not compost in place. As a result, you must still dispose of it in either a separate septic tank or toilet.

This toilet stands 18″ high, making it ideal for older people who require the additional height. Its extended seat measures 24″ long and provides a comfortable seating posture. And though the toilet does not flush, it includes a tiny air vent and fan at the back to deal with odor management.

This toilet is heavy since it is composed of fiberglass and connected with screws and metal hinges. It is not designed to be portable. Rather, you must empty the urine bucket and waste bucket one at a time. When the fiberglass breaks, the toilet is prone to odors and leaks.

The cracks are not dangerous. And if you love experimenting with DIY projects, you can fix them using basic home DIY materials. However, it takes a significant amount of time. Moreover, to keep the toilet in good working order, you must give it special attention. As a result, it may turn out to be more complicated than it sounds.

If you are concerned about ‘terrible’ composting toilets, consider purchasing this toilet for the guest washroom. But it would help if you have extra care with it and probably drained it after each guest.

 

Pros

  • European style
  • Compact design
  • Feces and urine diverter
  • Includes vent, fan and hose to prevent odor

Cons

  • Prone to cracks

 

Overall review

Overall, this smart Sun-Mar composting toilet is recommended for people who love things pleasing to the eye. The only drawback is that it is prone to cracks as it is made from fiberglass.

 

 

 

 

Frequently Asked Questions about Composting Toilets

What is the use of composting toilet?

 

A composting toilet is waterless and converts human excrement into useable compost. Like any other traditional toilet, it collects waste. The key distinction is that the waste is kept and must be turned or spun regularly to aid in the composting period. In addition, the compost in the toilet, like a typical outdoor composter, has to be turned to let the waste composting process speed up.

You will need to add extra materials to the compost enclosed area to speed up the composting process and keep the stench under control. Depending on the style of the toilet, this might be sawdust, peat moss, or even popcorn.

 

Is it true that composting toilets stink?

 

When people think about compost toilets, people imagine the toilet stinking up the home. They aren’t. In truth, there is hardly any odor. Whatever little odor you may smell is similar to the scent of sawdust or wood.

 

Does a composting toilet have zoning requirements?

 

When it comes to compost toilets, there are no particular national building codes that apply. Instead, each county, city, and state establishes its construction code. You may locate your local requirements by doing a simple search on Google, but it is a good idea to check your local planning and zoning board before you buy a composting toilet.

 

Conclusion

 

Having the best composting toilet is one solution to helping our mother earth by conserving water and energy. Composting toilets are not just for tiny houses and travelers; you can also use them in your home as regular toilets to help lower your water bills while being environmentally friendly.

We hope this reviews mentioned above help you decide whether you want to shift into composting toilets or stick to the regular ones.
