The best RV composting toilet can turn human waste & toilet paper into compost. Such toilets do not require water. They may be powered by electricity for the process of composting. There are nonelectric variants as well that rely on the natural process of evaporation and decomposition.

Most toilets produce waste comprising of as much as ninety percent water. This water can be made to evaporate using some kind of ventilation system. The ventilation also eliminates or regulates odor. The solid waste is subjected to decomposition or a composting process to become fertilizer.

A composting toilet relies on moisture, oxygen, organic waste matter and heat to be adequately balanced for the composting process to be effective. Natural decomposition is facilitated by bacteria and other microorganisms. The ideal environment should be created for the composting process to be reliable and steadfast.

A composting toilet is a quintessential requirement in recreational vehicles. Such toilets are also used at homes, especially where there are gardens. There are different types of composting toilet with varying specifications and you should explore all relevant options to choose the best.

How to Compare Composting Toilets

Composting toilets are economical and environmentally friendly. Some are quite expensive but you need not spend a fortune. Not all composting toilets are equally effective so you must choose a reliable brand. You must compare everything from the capacity to how it works, the method of installation to the warranty before you can come up with a shortlist. There are broadly two types of composting toilet, self-contained unit and a central unit.

A self-contained composting toilet is smaller. The tank where the composting will happen is connected to the installed toilet. A central composting toilet has a separate tank. The tank is connected to the toilet but it is neither attached nor does it have to be exactly where the toilet is. Central composting toilets have greater capacity but they are irrelevant for recreational vehicles. You will need a self-contained composting toilet for your RV.

Self-contained composting toilets do not cost much and the installation is considerably easier. There is no separate tank. The size is compact but the capacity is limited so one must exercise caution to avoid waste overflow. Composting toilets require more frequent maintenance compared to regular toilets. The compost generated should be cleared out from time to time. If you are choosing a self-contained composting toilet that runs on electricity then you should ensure the connections are working fine. Else, the composting process will be hindered and you will have a crisis to deal with.

Always study the specifications and features, ease of installation and warranty of every relevant composting toilet for your recreational vehicle. Embark on an extensive comparison where every important specification or feature is considered and only the best are shortlisted. While dimensions or size is of more significance, you cannot dismiss the weight either. You must know how much additional weight your recreational vehicle will have to carry. You may have a preference for electrical or nonelectrical composting toilets depending on the availability of energy. Electrical toilets are better since they can expedite the composting process.

Always prioritize safety, warranty, and price without compromising on any quintessential feature you need. You may not want to spend a lot of money but cutting corners will get you an unsafe composting toilet. You do not want the waste to overflow or any pathogen to find its way out of the tank. You need a comprehensive warranty for a substantial period of time. Balance safety and warranty vis-à-vis the price to choose a reliable composting toilet.

Major Manufacturers of RV Composting Toilet

Dry composting toilets do not require plumbing. There is no need to flush and chemicals are not involved in the process. The natural process is environmentally safe and also does not pose any threat to the occupants of a recreational vehicle. Composting toilets have their small ecosystem that does not interact with the environment inside or outside the recreational vehicle. Of course, there is evaporation, ventilation, decomposition and the eventual composting but the toilet will not pose any threat to the safety or wellbeing of the passengers in an RV.

You should not consider manufacturers you have not heard of. Only credible brands can be trusted to have a reliable and safe composting toilet. Such an installation is not complex for the user but the specific processes are quite complicated. A composting toilet should be easy to use and it must be versatile too. The two market leaders in this niche are Sun-Mar and Nature’s Head. There are a few brands such as Separett that are equally credible.

Nature’s Head is the largest brand of composting toilet. The company has a few models to choose from. While the models have many similarities, there are some differences in design and hence the variation in price. Nature’s Head makes effective and durable composting toilets for recreational vehicles. Sun-Mar specializes in composting toilet for recreational vehicles. It is not the most affordable brand by a mile but it does have some great options. Many people gravitate towards Nature’s Head as the prices of Sun-Mar can be twice as much. Both these brands make portable composting toilets. Some models have additional features. The manufacturers also have replacement parts and accessories.

4 Best RV Composting Toilets

Nature’s Head Self Contained Composting Toilet

This is one of the best composting toilets for recreational vehicles. It is 22 inches x 20.5 inches x 21.7 inches in size. The toilet has an elongated seat and weighs 28lbs. It runs on 12 volts and 0.72 watts. There is an integrated fan for air circulation that operates quietly. The pack comes with a vent hose and stainless steel hardware. The toilet is big enough for two people using it full time and definitely for temporary use over the weekends or a short span of time. The product is manufactured in the United States and it has a five-year warranty.

This Nature’s Head model works for most people. Those who are particularly large may not find ideal comfort using the seat. The height is fine though. It is one of the lighter models available right now so it does not add much weight to your vehicle. Installation is easy and so is its use. The electricity required is minimal so running it should not be a problem for most recreational vehicles, even if the source of power is a battery in some cases. Nature’s Head has a reliable support team that is on standby whenever users need some assistance. The company has a comprehensive warranty so any possible malfunction is covered. The price is slightly higher than what you may want to pay but the product is worthwhile.

Separett Villa 9210

While Nature’s Head model is the best overall composting toilet, the Villa 9210 from Separett is the most compact and hence fitting for recreational vehicles. The toilet is 18 inches x 26.5 inches x 21.3 inches. It weighs 47lbs and runs on 12 volts direct current and 2.5 watts power. It needs 6 kWh per day to operate the one-speed fan. The fan operates quietly, producing less than 30 dB noise. The capacity of this composting toilet is three weeks for average use by a family. The pack comes with all essential parts including battery cable, mounting components, and a power adapter. The company has a five-year warranty.

The compact size of the composting toilet is one of its biggest strengths but it is also slightly heavier. This should not be much of a problem since it still weighs less than fifty pounds. The toilet can be installed rather easily and quickly. One does not require a professional or experienced technician for the installation. Villa 9210 can run on battery or you can hook it up with the generator. The warranty is substantial and the coverage includes all parts. The price is not a surprise given the category of composting toilet.

Sun-Mar Excel Non-Electric Self-Contained Composting Toilet

This is the best option if you do not want an electric composting toilet. Weighing 90 lbs, the nonelectric self-contained composting toilet from Sun-Mar is 36 inches x 36 inches x 28 inches. It is larger and heavier than the aforementioned options. The unit has a bio-drum that has sufficient capacity for up to four people using the toilet full time. The waste contained will not overflow for up to eight weekends. If you are using a recreational vehicle for fulltime living then you should observe the cycle and a weekly clearing out may be necessary during frequent use.

Sun-Mar offers an NSF/ANSI certified warranty for five years covering the fiberglass and for three years covering all other parts. Those who have a large family or plenty of people are going to use the toilet will find the capacity sufficient. The capacity is substantially greater than both models of Nature’s Head and Separett. Hence, the toilet is also much larger in size and will take up more space. There is no need for electricity so there is a modest saving in utility. The flipside is that the composting process takes a while longer than what is required by electric variants.

Installation of this model is easier since there are no electrical connections to set up. The three-year warranty on the parts is a bit limiting and especially for the price but Sun-Mar is a reliable brand so you are unlikely to be unlucky with your purchase. The large capacity and easy installation are definitely the two noteworthy strengths. The weight and the price are the wrinkles for many buyers.

Sun-Mar Compact Self-Contained Composting Toilet

This is one of the best composting toilets if you are looking for limited capacity. Sun-Mar has quite a few low profile options and this one is 33 inches x 21-1/2 inches x 28-1/2 inches. It weighs 90lbs and comes with a venting kit. The self-contained composting toilet is pest proof. It is an electric model and requires 110 volts standard power source. It runs on 125 watts.

Like the other model of Sun-Mar, this one too has a bio-drum and there is an emergency drain. The warranty is the same. There is a five-year warranty on the toilet itself, covering the fiberglass, and a three-year warranty for other parts. The small capacity obviously limits the number of people who can use the toilet full time. At the most two adults can use the toilet in a recreational vehicle. The warranty is NSF/ANSI certified.

Those who want a compact composting toilet with a small capacity will find this one to be a relevant option. For others, the capacity may be too limiting. Smaller recreational vehicles will find this one more appropriate but the weight does not put it in the lighter category of composting toilets. The self-contained unit is safe and the emergency drain is a useful feature. The pest proofing is also appreciable. The warranties are comprehensive. Installation is easy. The venting kit is easy to work with. Price remains a concern and so does its weight. The capacity will be just enough for two people.

Choose the Safest and Most Effective Composting Toilet for RV

A distinction should be drawn between portable toilets and composting toilets. There are companies making portable toilets that are advertised as appropriate for use in recreational vehicles. While portable toilets can be used in recreational vehicles, they need to be connected to a septic tank. There should be a black water tank and a grey water tank. If you do not have such tanks in your recreational vehicle or trailer, then you must choose a composting toilet. Portable toilets are not by definition or description of composting toilets. You will not get composting toilets priced at below a hundred or anywhere close. The best composting toilets are priced close to a thousand dollars. There are some models priced at fifteen hundred and above. You may not choose the most premium model but do not compromise on the safety or effectiveness of a composting toilet for your RV.
