Building your own home is always exciting. Building a tiny home, perhaps even more so! With a tiny, you embark on a journey of downsizing and decluttering your life. And, often, going off-grid, becoming more eco-friendly, and self-sufficient. Tinies are often placed into beautiful, natural landscapes. And, if your tiny's on wheels, you can change up the scenery every so often, going from one jaw-dropping location to the next!
Switching to a tiny, however, is a process with its own set of difficulties to navigate. There is often no sewerage connection on rural sites, and you can run into the question of how best to accommodate your toileting needs. Septic tanks are expensive, require water and periodic pumping out, and their installation has a big impact on grounds. Incinerating toilets are expensive to buy and use a lot of power, and drying toilets use high voltage fans and can be ineffective in cold, humid climates.
Composting toilets are ideal for tiny homes. They don't require any expensive additional infrastructure or water. They don't involve too much maintenance and are user-operator systems, meaning you are in charge of managing your waste and don't need to rely on any other services to do so. Plus, they are easily movable along with your home - when investing money into a system for your tiny, you want it to be mobile for when you move site!
So, which composting toilets are the best for tiny homes?
Our top recommendation for a tiny is a batching split-system composting toilet. Split-systems have good-sized composting chambers, meaning they take a while to fill up and are low maintenance.
See product as example:
Our split-systems come with porcelain pedestals, which sit in your bathroom looking luxurious (and, a lot like your 'regular' flushing toilet). Directly underneath the pedestal sits your composting chamber, connected via chute. The chamber sits underneath the floor and thus requires clearance under your structure - this space has to be accessible for swapping over of chambers.
Our systems come with two composting chambers, which are use on a rotational basis. Usually, (depending on use) the chambers are swapped over every three-six months. One chamber is 'in-use' - connected to the chute, collecting waste, and composting it. Once this chamber is full, you put an 'out-of-service' lid on it, and sit it outside for further maturation of the compost, during which time you put the second chamber into use. Once the second chamber is full, the contents of the first are ready to be buried in your designated land application area. All our batching chambers are on wheels and are easily dragged out and over to your burial site, and tipped over like a wheelbarrow for emptying. The chambers are also double-walled, providing heat retention and allowing leachate (excess liquids) to drain away from composting solids, through to the bottom compartment of the chamber, and then into a leachate soak-away via hose.
Like all our toilets, these systems are vented with a 12V fan. This can be run off mains, solar panel, or in the right circumstances - equipped with a wind-driven vent for completely power-free operation! The fan constantly draws air through the system, aerating the compost and sucking out odours through an external vent stack.
When you're ready to change scenery and the time comes to move - your split-system goes with you! The pedestal is secure in the bathroom, so all you have to do is disconnect your composting chamber, take out the chute (so that it doesn't drag on the road), and take them with you. Then, simply reassemble on the new site!
