Which composting toilets for RVs are best? 

When living the RV life, you don’t always have a nearby restroom. Having a toilet in your RV is both convenient for daily life and a lifesaver in emergency situations. While some RVs come equipped with a built-in toilet, a composting toilet is a great alternative to traditional flushers.

If you’re a traveler and own an RV, or if you’re just considering ways to positively impact the environment, then a composting toilet is a solution. Be sure to consider the Nature’s Head Self-Contained Composting Toilet if you’re looking for the best self-contained composting toilet on the market.. 

Benefits of using a composting toilet for your RV

Reduced odor

A lot of travelers considering a composting toilet for their RV are concerned about the smell. That simply isn’t something you need to worry about with a composting toilet. Composting toilets smell far less bad than any water-flushing RV toilet. Since the waste isn’t sitting around and mixing together, there aren’t the same unpleasant gases and odors. Liquid waste is carefully stored while solid waste is turned into compost, so you don’t get the bad sewage smell you’re dreading.

Eco-friendliness

Simply the fact that you’re not using as much water to flush means you’re preserving water. Any longtime road traveler understands how valuable freshwater is. Saving water means taking fewer trips to fill up, camping longer and making more use of your water. 

Eliminates the need for a black water tank

If you’ve ever cleaned out your RVs black water tank, then you know the horrendous sights and smells involved. While a weekend camper may not need to be emptied all that often, any full-time RVers or long-term travelers need to clean out their black water tank every week or two. This means taking a lot of dump station trips. A composting toilet not only eliminates the weight and space needed by a black water tank, but it eliminates the nasty process of dumping soggy sewage.
