Many of these units feature detachable tanks, which allow you to easily dispose of the waste.

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.
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.
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.
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.
- 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.
