Choosing Your Composting Toilet: A Simple Buying Guide
Thinking about a composting toilet? It’s a great way to save water and turn waste into useful soil amendment. But which one should you choose? This guide breaks down what matters most.
Key Features to Look For
When shopping, look closely at these main features. They decide how well the toilet works for you.
1. Ventilation System
Good airflow is crucial. A composting toilet needs a fan or vent pipe to pull odors out of the bathroom. Look for models with a reliable, low-power fan. This keeps your space smelling fresh.
2. Separation Mechanism
Many composting toilets separate liquids (urine) from solids. Separating urine speeds up composting and reduces smell significantly. Check if the model has a built-in separator or if you need to add one.
3. Capacity and Size
Consider how many people use the toilet daily. Small units might need emptying every few weeks for a family of four. Larger, self-contained units can go much longer. Also, measure your space to ensure it fits!
4. Heating Element (Optional but Helpful)
Some high-end models include a heater. Heat speeds up the breakdown of solids, making the process faster and reducing volume more quickly. This is great for full-time living.
Important Materials Matter
The materials used affect durability and maintenance.
- Plastic (HDPE or Polypropylene): Most modern toilets use sturdy plastic. It resists moisture well and is easy to clean. Make sure the plastic feels thick and won’t crack easily.
- Stainless Steel Components: Look for stainless steel hardware, especially in areas exposed to moisture. Steel lasts longer than regular metal parts.
- Insulation: If you plan to use the toilet in a cold climate (like an RV in winter), look for insulated bins. Insulation helps keep the composting process active even when temperatures drop.
Factors That Improve or Reduce Quality
Small design choices make a big difference in your daily experience.
What Improves Quality:
- Easy Access for Emptying: A pull-out drawer for solids makes emptying much simpler. If you have to dismantle the whole unit, you will dislike using it.
- Low Power Draw: If you rely on solar power (like in an off-grid cabin), a toilet that needs very little electricity for its fan is a huge plus.
- Effective Cover Material System: The toilet needs an easy way to add ‘cover material’ (like peat moss or wood shavings) after each use. A large, easy-to-fill container attached to the unit is best.
What Reduces Quality:
- Complex Plumbing (For Units Needing Water): Some systems use a small amount of water for flushing solids into a holding tank. If this tank is hard to reach or clean, quality goes down fast.
- Poor Sealing: If the lids or connections don’t seal tightly, odors can escape even with a good ventilation system.
User Experience and Use Cases
Think about where and how you will use the toilet.
Off-Grid Cabins or Tiny Homes:
These are perfect uses. They eliminate the need for a septic system or city sewer hookup. Look for models that handle high volumes between cleanings.
RVs and Vans:
Portability is key here. Smaller, lighter units that don’t require permanent plumbing connections are usually the best choice. Ensure the unit is stable during travel.
Weekend Use vs. Full-Time Living:
For weekend use, a simpler, smaller unit might work fine. If you live in it full-time, invest in a larger unit with better heating or a more robust separation system to handle constant waste.
Frequently Asked Questions (FAQ)
Q: Do composting toilets really smell bad?
A: No, not if they work correctly. A well-vented, properly managed unit should smell no worse than a regular bathroom. The smell comes from moisture buildup, so good ventilation is the secret.
Q: How often do I have to empty the waste?
A: This depends on the size and use. A small unit for two people might need emptying every 4–6 weeks. Larger, central units might only need emptying a couple of times a year.
Q: What is the “cover material”?
A: Cover material is something dry, like sawdust, wood shavings, or peat moss. You add it after using the toilet. It absorbs extra moisture and keeps the composting material fluffy, which helps air move through it.
Q: Do I need electricity for a composting toilet?
A: Most models need a small amount of power to run the ventilation fan. If you are totally off-grid, look for models with very low wattage requirements or solar options.
Q: Is the end product safe?
A: Yes, when fully composted, the end product is safe and looks like rich soil. However, most people only compost the solids and dispose of the liquid urine separately (often by watering plants with it after dilution). Always follow the manufacturer’s guidelines for safe processing times.
Q: Can I install one myself?
A: Many self-contained units are plug-and-play; you just need to vent them outside. Units that require plumbing for urine drainage are a bit more involved, but most handy homeowners can manage the installation.
Q: Are composting toilets expensive?
A: Prices vary widely. Simple portable units start low, but advanced, full-sized models with heaters and automatic turners can cost much more than a standard flush toilet. Think of it as an investment in water savings and independence.
Q: Do I need a special bathroom setup?
A: You need space for the unit itself and a way to vent the air outside, usually through a small pipe going up through the roof or wall. You do not need a water line or a sewer connection.
Q: What about winter use?
A: If the toilet gets too cold, the composting process slows down or stops. For cold climates, use an insulated unit or a model with an electric heating element to keep the internal temperature up.
Q: Are they hard to clean?
A: Cleaning is usually simple. You empty the solid container, and then you wipe down the bowl and the urine diverter occasionally. Since there is no standing water, cleaning tends to be less messy than a traditional toilet.
