The Best Composting Toilets for Smaller Living Spaces

If you have an RV, a tiny home, or a boat, then a composting toilet is a convenient option for your lifestyle. Here are some composting toilets that are perfect for smaller living spaces.

A composting toilet separates liquids from solids and turns human waste into compost-like material. These toilets are essentially dry toilets because there is no plumbing or flushing involved, and this can come in handy for certain types of living situations. It’s environmentally friendly, it improves soil fertility in gardens, and they require little or no water. If you’re looking for a composting toilet, here are some we recommend.

Finding The Right Composting Toilet

Here are some things to consider:

• Space: The most important factor to keep in mind is your available space. Determine how much space you have to work with before deciding on which composting toilet is best for you. If you’re working in particularly tight quarters, consider a compact model.
• Family Size: If it’s just you or one other person, then you won’t need a big composting toilet. However, if you’re planning on using this toilet for the entire household, then look for larger models.
