Choosing the Right Composting Toilet for Your RV Adventure
Switching to a composting toilet for your RV offers freedom and fewer stops at the dump station. These systems manage waste naturally, turning it into usable compost. But picking the right one takes some homework. This guide helps you find the perfect fit for your mobile home.
Key Features to Look For
When shopping, certain features really matter for RV use. Think about how you plan to use your RV—weekends or full-time living greatly affects your needs.
1. Ventilation System Quality
Good airflow is critical. A high-quality fan pulls odors out of the RV. Look for powerful, quiet, and energy-efficient fans. Poor ventilation means bad smells inside your home on wheels.
2. Capacity and Size
Measure the space where the toilet will sit. RVs have tight spots! Also, consider the size of the solid waste container. If you travel solo for short trips, a smaller container works. Full-time RVers need large capacity tanks to avoid constant emptying.
3. Liquid Management
Composting toilets separate liquids (urine) from solids. Check how the liquid waste is handled. Some require a separate holding tank that needs frequent emptying. Others use a hose connection to an external tank or drain, which is much easier for long trips.
4. Power Requirements
Most composting toilets need electricity to run the fan and sometimes the agitator (mixer). Check the voltage (usually 12V DC, perfect for RV batteries) and the amperage draw. Low power draw keeps your batteries lasting longer.
Important Materials and Construction
The materials used directly impact the toilet’s durability and cleaning ease.
- Toilet Housing: Sturdy, UV-resistant plastic is common. It resists stains and is lightweight. Stainless steel components offer extra durability, especially around the hinges and connections.
- Waste Container: The solid waste bin should be made of durable, easy-to-clean plastic. Some high-end models use liners that make emptying cleaner.
- Seals and Gaskets: Ensure all seals are robust. Good seals prevent leaks and keep smells contained when the unit is not actively venting.
Factors That Improve or Reduce Quality
What makes one unit better than another?
Improving Factors:
- Automatic Mixing/Agitation: Some toilets have a simple handle you turn, but automatic mixers ensure the composting material stays fluffy. This speeds up decomposition and reduces odors.
- Self-Contained Drying System: Units that use heating elements to gently dry the solids reduce moisture, which prevents smells and speeds up composting.
Reducing Factors:
- Complex Electric Systems: Too many complicated electronics mean more things can break down far from a repair shop. Simple, robust mechanisms last longer.
- Small or Awkwardly Placed Urine Bottle: If the urine tank is tiny or hard to remove, you end up dealing with it too often. This lowers the user experience significantly.
User Experience and Use Cases
How you use your RV dictates the best toilet for you.
Weekend Warriors: If you only use your RV for a few days at a time, a simple, portable composting toilet might work well. These often do not require permanent plumbing connections. They are easy to install and remove.
Full-Time Nomads: Full-timers need high capacity and minimal maintenance. Look for models that connect directly to an external holding tank or use a large, integrated composting drum. Ease of solids removal is paramount.
Installation: Some units drop right in where your old RV toilet was. Others require more complex venting installation through the RV roof or wall. Always check the required installation complexity before buying.
10 Frequently Asked Questions (FAQ) About RV Composting Toilets
Q: Do composting toilets smell bad in an RV?
A: No, a properly installed and maintained composting toilet should not smell bad. The powerful, continuous ventilation system pulls all odors outside the RV.
Q: How often do I have to empty the solid waste tank?
A: This depends on the size of the tank and how many people use it. Typically, a two-person unit needs emptying every 3 to 6 weeks.
Q: Can I use my RV toilet while driving?
A: Yes, most RV composting toilets can be used while the vehicle is moving. The vent fan should remain on.
Q: What material do I use to cover the solids?
A: You must add a carbon-rich cover material after each use. Common materials are peat moss, coconut coir, or specialized wood shavings.
Q: Do these toilets use a lot of battery power?
A: They use very little power, usually just enough to run a small 12V fan constantly. This is generally not a major drain on RV batteries.
Q: Are composting toilets difficult to install?
A: Simple drop-in models are easy. Units requiring roof venting or complex plumbing connections need more effort or professional help.
Q: What happens to the urine?
A: Urine is separated into a small holding tank or diverted via a hose. It must be emptied regularly, as it is mostly water and salts.
Q: Can I use regular toilet paper?
A: Yes, most RV composting toilets allow you to use regular toilet paper. It gets dropped right into the solids bin with the waste.
Q: What is the initial cost compared to a regular RV toilet?
A: Composting toilets are significantly more expensive upfront than standard RV flush toilets, but they save money long-term by eliminating black tank dumping fees.
Q: Are they allowed everywhere?
A: Composting toilets are generally allowed anywhere you park, as they do not use or create black water. Always check specific campground or park rules if you have concerns.
