    Best Overall

    This portable toilet is designed for camping, RVs, boats, trucks, and more. It features a sleek and modern design with a comfortable seat height. It comes with a battery-powered flushing mechanism, a carrying handle, integrated toilet paper holder, and a tank level indicator.


    The toilet is odorless and leak-proof. There's no smell even after several days and uses.

    Benefits of Composting Toilets for RVs

    • No plumbing required. The best compost toilet for RVs allows you to do your business without worrying about installing plumbing lines and pumps. They are easy to use and clean and are great for off-grid living.
    • Earth-friendly. A portable composting toilet for RVs uses little to no water, and you can recycle human waste and turn it into fertilizer. Composted waste does not need to go through a treatment plant.
    • Convenient. When you're camping or RVing, it can be uncomfortable to head into the woods when nature calls. The best composting toilet for RV use is a good alternative.
    • Save money. The best composting toilets for RVs don't use as much water as traditional toilets. They are great if you want to reduce your water bill.

    Types of Composting Toilets for RVs

    Self-Contained

    A self-contained composting toilet includes all the required parts in a single unit. If you have limited space or need a portable toilet for camping, RVing, boating, tiny homes, etc., this type of system is ideal. Many of these units feature detachable tanks, which allow you to easily dispose of the waste.

    Centralized System

    This type of composting toilet features a centralized tank that's installed outside or underneath a home. When you flush, the waste is sent to a storage tank. Different centralized systems have different flushing mechanisms and storage chambers. They are very similar to full size traditional toilets but are not portable.

    Top Brands

    Nature’s Head

    Nature’s Head was founded by two sailors in 2006. They created a product that can be used on RVs, boats, in tiny houses, and more. The company is located in Van Buren, Ohio. One of its top products is the Nature’s Head Self Contained Composting toilet.

    Camco

    Camco, based in Greensboro, North Carolina, was founded in 1966. The company produces a wide variety of products for RVers, including water heaters, appliances, air conditioning and heating units, and toilets and accessories. One popular product is the Camco Portable Travel Toilet.

    Thetford

    Based in Ann Arbor, Michigan, Thetford is one of the top manufacturers of mobile sanitation products for RVing, camping, and trucking. It makes low-water-use toilets, self-contained toilets, waste holding tank deodorants, and more, including the Porta Potti White Thetford Corp.

    Composting Toilets for RVs Pricing

    • Under $150: There are several user-friendly RV composting toilets available for a relatively low price. They tend to be portable but are likely to have smaller tank capacities, so they're less ideal for larger families. They also have odor-free features.
    • Over $150: Some of the best RV composting toilets cost several hundred dollars. They are much more durable than their cheaper counterparts and include features such as stainless steel hardware, elongated seats, vent hoses and fans, and separate chambers for liquid and solid waste.

    Key Features

    Size

    One of the most important features to consider is the size of the composting toilet. Look at the space in your RV, van, or camper, and measure the dimensions. Compare them with the size of the head toilet. Some are smaller than others and are more portable. Some are also lighter in weight. 

    Durability

    Ideally, a head composting toilet will last for several years. Most of them are made of plastic and vitreous china, which are not as durable as some other materials. Look for sturdy designs and high-quality components that can tolerate the composting process for many years. One of the best ways to gauge durability is by reading consumer reviews.

    Tank Capacity

    Composting toilet tanks come in a variety of sizes. If you're a solo traveler, you can get by with a smaller storage tank, which is less expensive than products with larger tanks. Families need higher capacity tanks, especially if they don't want to empty the waste every day. Most manufactures include the capacity in their specifications.

    Ease of Cleaning

    Higher-quality composting toilets are easier to clean because they are constructed of better materials. Some brands lose integrity over time. For example, the storage tank may become difficult to open, which can result in a spill. Some models have better rinsing mechanisms than others, preventing you from scrubbing them after every use. Also, look for models that you can easily clean and don’t require special equipment.

    Other Considerations

    • Separate Waste Areas: These types of toilets separate liquid waste from solid waste. The advantage to this is that they are often easier to clean. In addition, these composting toilets generally produce less odor. Overall, this makes upkeep a lot more pleasant.
    • Seat Height: Some composting RV toilets are made to resemble standard toilet seats. They're around the same height, which is much more comfortable than a shorter seat. In addition, some include elongated seats, which are also more comfortable. If you want to recreate the home experience, look for products that are similar to traditional toilets.
    • Vents and Fans: One reason why some people avoid composting toilets is the odor. They are designed to seal in odor and leaks, and some feature extra protection in the form of venting and fans. Sometimes you can connect the vent to an existing line in your camper.

    Tips

    • Decide whether you want a model that will be left in your RV full time or one that you can take out at campgrounds, hunting sites, and the like.
    • Picking the right size can be tricky. Make sure the one you buy fits in the space you have available, but don’t get one so large it dominates the bathroom.
    • Be careful when setting up the ventilation system, as doing it improperly could lead to bugs getting into your RV. When in doubt, have a professional do it.

    FAQs

    Q: Do composting toilets stink?

    A: They will if they’re not properly maintained, but if you’re diligent with their upkeep, they shouldn’t smell much worse than a regular toilet. Don’t get one if you’re not prepared to do a little maintenance work periodically.

    Q: Why should I consider a composting toilet?

    A: They work as well as regular toilets, but since they typically don’t use much (or any) water, they have a much smaller environmental impact. In addition to making you feel good about being conscientious, that can also save you money on water costs.

    Q: Are they difficult to install?

    A: Some can be tricky, but they’re not all challenging. However, some require making alterations to your RV, so if you’re unsure of how to proceed, consider hiring a pro to put it in.
