Thinktank Waterless Composting Toilet – Made in Canada 🇨🇦

The Thinktank Waterless Composting Toilet is a premium urine-diverting toilet designed for off-grid cabins, tiny homes, RVs, and eco-conscious installations. Its patented airtight trap-door system delivers superior odor control while preventing heat loss by drawing ventilation air from outside—not your living space. Built for comfort, durability, and minimal maintenance, the Thinktank offers a cleaner, stronger, and more user-friendly alternative to traditional composting toilets.
