The Perfect Fit For Your Lifestlye

Every style of install has unique challenges. Find out how we have built the perfect toilets for your lifestyle.


We provide a fan and vent that should be installed to an external wall or ceiling. If on a boat, a common solution it to vent into the anchor locker. For more help with installation, check out our Installation Guide.

By seperating both, It helps to reduce moisture in solid waste, speeding up composting and massively reducing odors. It also helps manage nutrient levels, ensuring a more effienct process. Finally, it reduces the amount of times you will need to empty the solids tank.

Once urine and feces are separated, the solid waste is mixed with a carbon-rich material, like our Coco Peat Bricks, which act as a bulking agent. This mixture creates the perfect environment for aerobic bacteria to thrive. These bacteria break down the waste into compost, a nutrient-rich soil additive, through a natural, odor-free process.

Absolutely! More and more liveaboards are moving to Air Head Toilets because it allows you to be take your boat to areas which are tightly regulated by waste water laws or regular pump outs. It is also much easier to maintain, with fewer moving parts than a traditional manuel or electric head would require, meaning you can carry less spares, and spend less time dealing with toilet problems.

Yes, Air Head Toilets are completely custom. When ordering, you can choose which options suit your install best, allowing you to easily build the toilet around your space.

Check out our dimensions page for more detail!

Optimal composting occurs at temperatures between 55°F (13°C) and 100°F (38°C). Within this range, the aerobic bacteria that break down waste are most active, leading to efficient composting and odor control. At lower temperatures, the composting process slows down, as microbial activity decreases. Conversely, if the temperature gets too high, it can kill the beneficial bacteria or lead to excessive moisture loss, hindering the composting process. The Air Head is designed to maintain a balanced environment for composting, but it’s beneficial to be mindful of external temperatures.

Generally, restrictions will be different depending on location, but typically it is ok to use any compost in flower beds, or in your garden, just don’t use it on anything you plan to eat (fruit or veggies). It is generally permitted to dispose of it in the trash as long as it is in a sealed bag. But you are still advised to consult local authorities to find out if there are any location specific rules to follow.

  1. In general, there are very few things that can go wrong in your system, which makes maintenance great. However, if you are going away for months or years, we recommend that you carry:

    • Fan Replacement: Keeping a spare fan (and electrical wiring) ensures the ventilation system remains operational.
    • Spare Lids: In case you drop or misplace a lid for the liquids, order a few extra.
    • Bulking Agent: While not a “part,” having an extra supply ensures you can maintain the proper composting mix.

    Having these items ensures that you can deal with most maintenance or repair needs without a trip to town, keeping your system running smoothly in off-grid situations.

Yes! Our brand new model, Tejo, has been designed with this in mind. Simply install a hose directly between the Air Head, and your thru-hull (allowing for a vent or loop above water line to prevent sea water coming back in). By eliminating the urine on the toilet, it reduces the amount of time you need to remember to empty the toilet

Yes! There is no better option for RVers, either full time, or weekenders. It opens up so many opportunities to not have to find sites with pump out facilities, or places which sell chemicals. Instead, you are free to roam wherever you want, not planning your route around your toilet!

So, the solids tank can take, on average 80 uses. So, if 2 people use the toilet every day, it will last 1 month. But if 2 people are only using it at weekends, it can easily last a full season. Of course it can be emptied more frequently if you are happy to do so. For liquids it will also depend on usage. But, for 2 people, the small tank will need emptied every 1-2 days, and the large tank will last 2-4 days.

When at home, solids from your Air Head should be emptied into a dedicated compost pile or bin, where they’ll further decompose into usable compost for non-edible plants. Away from home, the solids can be placed in a biodegradable bag and disposed of in a trash receptacle.

The fan is designed to provide continuous air flow, aiding in the composting process and helping to minimize odors by evaporating excess moisture. While it’s generally recommended to keep the fan running to ensure the system operates effectively, it can be turned off for short periods if necessary. Extended periods without the fan may hinder the composting process and could lead to increased odors.

We make it as simple as possible. Clean the unit with natural cleaners to maintain hygiene. Inspect and clean the fan and vent system for unobstructed airflow, and agitate the composting material to aid decomposition. Check the rubber seals for integrity to prevent leaks and odors. Adjusting the bulking agent helps maintain optimal compost moisture. Following these simple routines ensures your toilet remains efficient and hygienic over time.

Winterizing the Air Head Composting Toilet in an RV or boat involves a few key steps to ensure it remains functional and odor-free during colder months:

  1. Empty the Unit: Empty both solids and urine containers before cold weather.
  2. Clean Thoroughly: Use natural cleaners for a thorough clean of the entire unit.
  3. Add Antifreeze: If occassionally in use, add non-toxic antifreeze to the urine bottle.
  4. Maintain Ventilation: Keep the fan and ventilation system running to prevent moisture build-up.
  5. Insulate Pipes/Vents: Insulate external vents or pipes against freezing.
  6. Monitor Moisture: Adjust bulking material addition to manage moisture in colder temperatures.
  7. Use a Heater: In extreme cold temperatures, consider a small heater near the unit to maintain composting temperatures.

Absolutely! We have made the install very user friendly for anyone to be able to have up and running in a few hours. Simply follow our installation guide, here:

Yes, additional hoses can be added to the Air Head Composting Toilet to accommodate longer vent paths. This flexibility allows for customized installation in various settings, including RVs, boats, and off-grid homes, ensuring effective odor control and proper air flow regardless of the distance to the exterior vent point.

It’s best to avoid chemical-based household cleaners, like bleach, in you Air Head as they can disrupt the composting process by killing beneficial bacteria. Opt for natural, non-toxic cleaners like vinegar, baking soda, or eco-friendly products designed for composting toilets. These alternatives keep your toilet clean and ensure the composting system works effectively and safely for the environment.

Our brand new model, Tejo, was built with this in mind. It comes without a urine tank, which allows you to install the urine directly to an existing holding tank. This allows you to go much longer without emptying tanks, improving the whole experience.

One of the best things about the Air Head Tejo is how it effectively manages waste without any noticeable odors, which was a big concern for me. It also uses very little water, making it an environmentally friendly option. The compact design fits well in my small space.

There were a couple of minor issues during installation, but the customer support team was helpful and responsive.
