Introduction: Best Compost Toilet for Tiny House

When it comes to tiny house living, maximizing space and minimizing waste are key priorities. One way to achieve both of these goals is by installing a composting toilet. But what exactly is a composting toilet, and how does it work? What are the best composting toilets for tiny houses?

A composting toilet uses a combination of aerobic decomposition and evaporation to break down and transform human waste into a stable, soil-like material. Unlike traditional flush toilets, which require a constant supply of water to flush away waste, composting toilets rely on natural processes to break down and treat the waste.

There are several types of composting toilets, each with unique features and benefits. Some are designed to be compact and portable, making them ideal for tiny houses with limited space. Others are more advanced and feature self-contained composting systems, allowing easy and convenient composting without needing external bins or containers.

Regardless of the type of composting toilet you choose, they all offer a number of benefits over traditional flush toilets. In addition to saving water and reducing waste, composting toilets minimizes the strain on septic systems and municipal sewage treatment plants, making them more sustainable and eco-friendly.

So, if you’re ready to embrace a more sustainable lifestyle and install a composting toilet in your tiny house, read our picks for the best composting toilets for tiny houses on the market below! Each option has been carefully selected for its efficiency, durability, and convenience, making them the perfect choice for any tiny house dwelling looking to minimize its environmental impact.

1 – Nature’s Head Self-Contained Composting Toilet

I highly recommend the Nature’s Head Composting Toilet for anyone in need of a reliable toilet for their tiny house. Its simple design and few moving parts make it a breeze to install – just connect a 2-inch vent hose to the outside and ensure it’s wired for either 12v or 120v power.

The electrical connection powers the exhaust fan that keeps the solids bin odor-free, making it easy to maintain a pleasant bathroom experience. Using the toilet is just as straightforward – simply fill the solids bin with the required bulking material and plug it in. The liquid catch bottle on the front can be mixed with water and safely emptied into a flower bed, giving you an eco-friendly option for waste disposal.

Overall, the Nature’s Head Composting Toilet is a top-performing choice that I wholeheartedly recommend.

Pros:

  • The Nature’s Head Composting Toilet separates solids and liquids, allowing for easy and environmentally-friendly waste disposal.
  • With regular use by two people, the toilet only needs to be cleaned out every six weeks.
  • Its simple design includes relatively few moving parts, reducing the likelihood of breakdowns.
  • The toilet is fully sealed, making it suitable for travel.
  • It offers a competitive price compared to other options on the market.

Cons:

  • The liquid catch bottle on the Nature’s Head Composting Toilet needs to be emptied regularly.
  • Solid waste may take longer to fully compost, which may require the use of an external composter or an additional solids bin.
  • The main compartment of the toilet should be emptied every 1.5-2 weeks, which can be unpleasant due to the wet and smelly waste.
  • The fan on the toilet may not be very powerful, causing the waste to not dry out as effectively and potentially causing backflow of air when the bathroom fan is on during a shower.
  • Using the toilet may require more toilet paper, as it needs to be wiped down after each use and hard-to-reach areas may require disassembling the toilet and using a pressure washer with a fine-tip nozzle.

How Do Composting Toilets Work in Tiny Homes?

More people are turning to a minimalist lifestyle to save money, benefit the environment, and in some cases, live off the grade. With tiny homes being a major makeup of that discussion, people’s primary concerns revolve around the bathroom. There are so many options to choose from, and composting toilets are a popular option since it covers such a wide range of needs. As a result, many people ask, how do composting toilets work in tiny homes?

This guide is meant to highlight how composting toilets work and why you may want to consider one for your tiny home. We’ll discuss how the toilets work, waste management, maintenance requirements, benefits, drawbacks, and a general FAQ. By the end, you’ll know more about composting toilets and if it’s the right fit for you.

How Do Composting Toilets Work in Tiny Homes

What is a Tiny Home?

There are two main schools of thought about what a tiny home is. First, there’s the architectural standpoint, where it’s a home that’s built under 600 square feet. It’s vital to note that most tiny homes are 225 square feet and are typically eight times smaller than the average home. The build quality and style vary, just like normal homes.

The other point revolves around the social movement and concept behind living with less. Its idea is based on the average person’s impact on the planet and how individual choices can make for a better future. Hence, Tiny Homes have exploded in popularity over the last few years and will continue to grow.

How Composting Toilets Work in a Tiny Home

A composting toilet is a great option for a tiny home because it’s waterless. That way you don’t have to worry about hooking up to a sewage system or septic tank. How it works is very interesting. A diverting system collects waste and liquid separate from one another.

The process allows the waste to break down and dry. Keeping it away from the urine helps mitigate the smell that’s commonly tied with using the bathroom. Just like a standard toilet, composting toilets are connected to the floor and don’t use chemicals. So all you have to do is buy a composting toilet and install it in your tiny home. Remember to follow the instructions for absorbents and waste management.

What Do You Do With The Waste From a Composting Toilet?

Where the waste goes depends on the composting toilet type. Some may require wood chips or moss to help dry the waste, while more expensive units might not. Regardless, all composting toilets require manual emptying. You can add the waste to a compost pile, or spread it around trees or lawns.

What Are the Maintenance Requirements of a Composting Toilet in a Tiny Home?

As you can imagine, maintenance requirements vary depending on the specific composting toilet. Seeing as every toilet varies in its quality, much of it comes down to the recommended instructions from the company behind the toilet. Still, there are some general rules you can follow.

A good habit to get in is to clean the filter by the fan whenever you have to empty the solid waste bucket. It’s also worth rinsing the buckets with water and wiping down the toilet with disinfectant around the same time.

Some people pour hot water down the urine bowl to help eliminate mineral buildup and keep the pipe draining okay. You can also use bi-carb soda and vinegar. Lastly, like a normal toilet, remember to wipe it down once a week to keep bacteria from growing.

Benefits of Using a Composting Toilet in a Tiny Home

No Plumbing Requirement

If you can build a tiny home, avoiding plumbing will make it much easier for you, and a composting toilet fits that bill. It’s also ideal in areas where plumbing isn’t readily available, so you don’t have to worry about a sewage system or septic tank.

Are There Drawbacks to a Composting Toilet?

Like anything else, there are some drawbacks to a composting toilet. It may take you a while to get used to it, you have to manually empty it unlike a standard toilet, and there are health risks if you don’t install or maintain it properly.
