Buying Guide
Choosing the right composting toilet for your RV depends on several factors. Here are some tips to help you make the best decision:
- Size and Space: Measure the available space in your RV. Compact models are best for smaller RVs, while larger models offer more capacity.
- Odor Control: Consider urine-diverting toilets if odor control is a top priority. These models separate liquid and solid waste, minimizing smells.

Here are some frequently asked questions about composting toilets for RVs:
Q: How often do I need to empty a composting toilet?
