The Best Composting Toilet for Van Life

The Buying Guide

Shopping for a composting toilet can be tough. At a glance, you will think that all toilets are made the same. On the contrary, there are tons of differences when you get to the details about composting toilets.

Type of Composting Toilets for cabin

If you have never used composting toilets, you might be having lots of questions about the various types available and how they work. Whereas the working process of composting toilets is similar, their use may slightly vary. Some of the different types of composting toilets for sale include:

Self-contained

Self-contained composting toilets are a perfect option for residential homes. They can be either electrical or non-electrical and often come with several likable features. Electrical self-contained toilets have heating elements and a fan. The fan dissipates odors, keeping your toilet area free from unwanted smells. The heating unit, on the other hand, will help in evaporating liquids. Depending on the brand and model you choose, electrical models can consume between 80 and 150 watts.

Self-contained composting toilets are advantageous in several ways and they can be used without complex plumbing systems – they don’t require water to function. However, you should assemble it correctly, especially the toilet’s vent. Since the unit will evaporate liquids, you don’t have to worry about dumping wastes. In general, self-contained units resemble the typical toilets you’ll find in regular homes and can handle daily use. They are also easy to clean and maintain.

Central toilets

Central composting toilets come with either a one-pint flush system or a waterless system. Regardless of your choice, both are connected to a compost unit in the basement or outside your home. One-pint systems are less eco-friendly and not typical composting toilets since they require water and plumbing. As the name suggests, these units consume approximately one-pint per flush, which is less compared to traditional two-piece or one-piece toilets that use more than 1.6 gallons per flush.

Composting units of these toilets should be installed approximately 20 feet away from the toilet. This means that plumbing connections from the toilet to the composter are a necessity. As a result, they are an eco-friendly option that uses less water – a great option for residential use.

Waterless central composting systems, on the other hand, use no water. However, they use an airflow unit with plumbing pipe connections to transfer the waste from the toilet to the composting unit. They are a great water-saving option for those who reside in dry areas and looking to cut down on water bills. Additionally, waterless central composting toilets work well for cabin or vacation homes.

Split toilet systems

Split toilet systems are increasingly becoming a popular option for countryside residential homes. These units not only simplify your life by making the composting toilet easier to use but are also more affordable compared to other technologically advanced residential composting toilets. As the name suggests, split toilets are split into two areas – the tank and pedestal.

The pedestal comprises of the toilet area with a toilet seat. The tank is underneath the pedestal and houses the waste. Split units are great for home use as they typically separate the liquid from solid waste. Note that you will need to dump the solid waste in your compost bin whenever the tank fills up. Don’t wait until it is too full, though.

RV composting toilets

As the name suggests, RV toilets are designed to be used in RVs. However, some are portable enough to be used on camping trips and road trips. RVs typically have a black tank that holds the waste, and you will have to empty out the waste in specific locations. However, using a composting toilet in an RV eliminates the need for using this tank, spraying harsh chemicals, or flushing waste.

As one of the best composting toilets on our list, RV composting toilets have a seating area and tank below. Some may include a separate container for liquids and solids, while others use the bucket-type system. Regardless of your choice, RV composting toilets are easy to use and clean.

Features of the Best Composting Toilet for van life

Below are the critical features to look for when choosing the best composting toilet:

Physical space

What is the ideal size and shape of your composting unit? Is your toilet spacious enough? While some units are designed for tight corners, others can fit everywhere. Some have to be installed above the toilet hole and linked to regular plumbing, while others require no plumbing at all.

You should identify where you plan to install the toilet before you make the purchase decision. This involves identifying the distance between the toilet and power and water sources. Other considerations include the type of flooring and distance to the wall, among others.

Tank capacity

How many people will be using the composting toilet? Well, some units can go for months before being emptied while others can only last a few days. This definitely depends on the number of people using the toilet and the frequency of use. Vacation cottages with composting toilets, for instance, are rarely used and won’t fill up quickly.

But if you’re shopping for a composting toilet for your tiny house, an RV, or an off-grid settlement, you need a composting toilet that can handle everyday use for prolonged periods. Estimating the intended use will help you choose a unit with sufficient storage capacity. Ideally, go for a unit that can go for one month or two before requiring emptying.

Local government regulations

In some states, you will need special permits to install and use a composting toilet. If you live in such regions, consult your local authorities before installing your unit. The authorities will inform you of the required regulations and provide a list of the composting toilet types approved for use in your area.

Besides, some units in our composting toilet reviews are self-contained, while others require that you dig a septic tank below the toilet or link it to a composting device within your backyard. Whichever the case, you will need a municipal permit and adhere to local plumbing codes before proceeding with any construction.

Weight

You should also put serious considerations into the weight of the unit before making a purchase. Some units with small capacities are lightweight and can be used anywhere, be it upstairs or downstairs. However, some are heavy and bulky. Heavy units are not flexible and cannot be used in some areas, such as upstairs or camping sites.

Safety

Safety issues when using a composting toilet arise in two areas: within the compost and around electrical hook-ups. Purchasing a poorly designed and malfunctioning unit is a recipe for nasty bacteria and pathogen accumulation in your toilet. The best and easiest way to enhance the safety of compost toilets is by conducting regular maintenance and purchasing the best available composting toilet for sale. The second aspect of security is with electrical hook-ups. They should be routinely checked and maintained.

Warranty

If you maintain, clean, and regularly empty your composting toilet, there is no reason to worry about abrupt malfunctioning. However, it is still a good idea to confirm that the unit you purchase comes with a reliable manufacturer’s warranty. With this, you can be certain that you will get a replacement in case of unforeseen faults with the electrical system or any other parts.

Benefits of Using the Best Composting Toilets

  • Reduces water usage
  • Versatile – can be used anywhere, from RVs, to boats, to camping sites.
