Best Composting Toilets Under $1,100 (2025 Buyers Guide)
Your septic quote came back at $15,000. The outhouse is freezing in winter. The portable chemical toilet stinks and needs constant emptying. Meanwhile, composting toilet owners spend nothing on water bills, never pump septic tanks, and deal with waste once a month—odorlessly.
Quality composting toilets run $199-$1,035—from basic manual separators to electric mixing systems with sensors. Modern designs eliminate odor completely while turning waste into harmless compost you can actually use on non-food plants.
Five proven models reviewed. Different systems. This guide shows exactly what each handles, real maintenance requirements, and which matches your off-grid situation.

Frequently Asked Questions
Q: Do these really not smell? Yes, when used properly. Separation of liquids and solids prevents ammonia formation. The Nature’s Head and OGO have thousands of reviews confirming zero odor. Add peat moss or coconut coir and the fan (if equipped) handles the rest.
Q: How often do you empty them? Varies by use: Full-time couple empties solids every 3-6 weeks. Liquids need emptying every 2-3 days with regular use. The NOMAD uses bags you change as needed.
Q: Do you need special toilet paper? No, but single-ply breaks down faster. Marine/RV toilet paper works best. Some users switch to bidet attachments to reduce paper use entirely.
