Space and Structure Requirements
The layout of your tiny house plays a big role in selecting the right system. Start by measuring your bathroom area and take into account:
- The size of the toilet
- Space needed for maintenance
- Ventilation setup
- Access for emptying and cleaning tasks [1][3]
If you have under-floor space, a split system might be a better choice due to its larger capacity and simpler maintenance. For tighter spaces without under-floor access, self-contained units are a good option, though they require more frequent emptying [1].
Budget and Toilet Selection
Pre-made composting toilets generally cost between $700 and $2000. You'll also need to factor in expenses for ventilation systems, mounting hardware, and maintenance supplies. Want to save money? DIY systems can help cut costs but will demand more time and effort to build and maintain [2][4].
When selecting a toilet, consider:
- How complex the installation will be
- Maintenance requirements
- Energy consumption
- Durability of components
- Warranty options

Tools List
Having the right tools ready can make installation much smoother. Invest in reliable tools, especially the drill and jigsaw, for accurate ventilation cuts [2]. Here’s a basic list of what you’ll need:
- Power drill/driver
- Jigsaw
- Screwdrivers (both Phillips and flathead)
- Silicone sealant
- Utility knife
- Safety equipment (glasses, gloves, dust mask)
Keep in mind, the specific tools required might change based on the toilet model and the structure of your tiny house. If you're installing a split system, additional tools will be necessary for working with under-floor components [2].
Once everything is gathered, you can move on to the installation process, starting with preparing the site.
Installation Steps
Preparing the Site
Make sure the bathroom floor is stable, level, and capable of supporting the toilet's weight. For split systems, check that there's enough space under the floor to house the composting unit [1].
Use a jigsaw to cut precise openings for ventilation and urine diversion. The floor must be completely level, as even a small tilt can interfere with liquid separation.
Setting Up Ventilation
Install the ventilation pipe vertically to improve airflow [1]. Here's a breakdown of key components and their roles:
| Component | Installation Requirements | Purpose |
|---|---|---|
| Main Vent Pipe | Keep it vertical with few bends | Facilitates natural airflow |
| Electric Fan | Place near the external vent | Boosts air circulation |
| Seals | Use around pipe penetrations | Blocks moisture infiltration |
Ensure all vent connections are sealed tightly, and extend the pipe above the roofline for proper airflow. Once this is done, you're ready to position the toilet unit.
Installing the Toilet
Place the composting toilet unit in the marked location, ensuring it lines up with the pre-cut ventilation and drainage openings.
For the urine diversion system, set the liquids hose at a slight downward angle to prevent backflow [1].
Secure the toilet to the floor using the included hardware, and double-check these critical connections:
- Ventilation connections: Ensure the vent pipe is tightly sealed to the toilet.
- Urine diversion system: Confirm proper alignment and secure all fittings.
- Main unit mounting: Verify all mounting points are firmly fastened.
Test for stability and confirm the ventilation fan is working. Pour a small amount of water into the urine diversion system to check for proper drainage and no backflow.
Regular maintenance after installation will keep the system running efficiently and odor-free.
Maintenance and Care
Regular Cleaning and Checks
Keeping your composting toilet in top shape requires a regular cleaning and inspection routine. Here's a simple schedule to follow:
| Component | Maintenance Task | Frequency |
|---|---|---|
| Toilet Bowl | Clean the surface | Weekly |
| Urine Diversion System | Flush with water | Weekly |
| Ventilation System | Test functionality | Monthly |
| Composting Chamber | Check levels | Monthly |
| Mineral Buildup | Perform a deep clean | Monthly |
Make sure to inspect the ventilation system and urine diversion system every month to maintain proper airflow and drainage. For deep cleaning, a mix of bi-carb soda and vinegar works well to control odors effectively [3].
Compost Removal and Use
Empty the composting chamber every 2-3 months, or sooner if it fills up, odors arise, or decomposition slows down. Always wear gloves and follow safety guidelines when handling waste [1].
To keep composting conditions ideal, ensure the material stays damp (not overly wet), aerate it regularly, and maintain a temperature range of 55-65°F. Once the compost is fully processed, it can be safely used on non-edible plants and trees, provided local regulations allow it [1]. This practice aligns perfectly with the eco-conscious lifestyle often associated with tiny house living.
Staying on top of maintenance not only keeps your system running smoothly but also helps meet any relevant regulations, which we'll cover in the next section.
