The Best Composting Toilets for Van Life
A composting toilet is one of the most liberating additions to a van build. It eliminates the need for campground bathrooms, dump stations, and the hassle of chemical cassette toilets. Modern composting toilets separate liquid and solid waste, controlling odor naturally and composting solids into safe, inert material. They’re odor-free, easy to maintain, and genuinely practical for full-time van life.
1. Nature’s Head Self-Contained Composting Toilet
Nature’s Head is the most popular composting toilet among van lifers, and for good reason. Its robust construction, easy-to-empty design, and reliable odor control make it the gold standard. The spider handle agitator mixes the compost medium effectively, and the separate urine container needs emptying every few days.

2. Air Head Composting Toilet
Air Head is a close competitor to Nature’s Head with a slightly more compact footprint—ideal for tighter van builds. It uses the same liquid/solid separation system and a small 12V fan (about 0.04A) to vent odors outside. Many van lifers prefer its ergonomics and installation flexibility.

3. Separett Villa 9215 AC/DC
The Separett is a urine-diverting toilet rather than a traditional composting system. It uses biodegradable bags for solids (no medium required) and routes urine separately. It’s the easiest to maintain and has almost zero odor. Great for van lifers who want a toilet without the compost medium management.

- Size: Measure your toilet space carefully; most composting toilets are larger than cassette models.
- Venting: All composting toilets require an exhaust vent through the van wall or roof—plan your build accordingly.
- Medium: Peat moss or coco coir are the most common composting mediums; both are widely available and affordable.
- Liquid Capacity: Solo van lifers empty the liquid bottle every 2–3 days; couples may need daily emptying.
- Solids Capacity: Most units hold 4–6 weeks of solid waste for one person—proper medium management is key.
- Legal Disposal: Composted material can often be disposed of in trash; check local regulations.
Final Thoughts
A composting toilet is a genuine quality-of-life upgrade for full-time van lifers. The Nature’s Head remains the top choice for its durability and ease of use, while the Separett offers the simplest maintenance. Either way, the freedom of having your own bathroom on the road is hard to overstate.
