We asked hundreds of people across North America about their preferred composting or waterless toilet, and one result surprised us: DIY toilets are more popular than we expected.

So we put together an article about DIY composting toilets: the pros and cons, common mistakes to avoid, and what to think about before building one.

Hopefully this helps people navigate the confusing world of composting and waterless toilets.

Thinking about getting a composting toilet?

Most people don’t realize a few key things until after they buy one.

For example:
– It shouldn’t smell
– The best systems separate urine from solids
– Most need emptying every 3–4 weeks

We broke down the 10 most important things to know before choosing the right system 👇

What do you think we missed?

The Thinktank was featured at the 2025 Rich Earth Summit on Cape Cod.

The Rich Earth Institute advances urine nutrient reclamation (or "peecycling") through research, demonstration, and education. Based in Vermont, Rich Earth’s flagship program is the first and largest community-scale urine recycling program in the US.

By recycling the nutrients in urine, communities and gardeners can prevent downstream pollution, access an abundance of sustainable fertilizer, and conserve clean water.

We are happy that the Thinktank is one of the recommended toilets of the Rich Earth Institute, supporting science-based, real-world approaches to closing the nutrient cycle.

Many composting toilets draw air from your bathroom and vent it outside. The Thinktank is designed differently.

Our airtight system pulls fresh air in from outside, so you’re not blowing away your expensively heated or cooled indoor air.

The secret is our patented silicone seal built into the lid. When you close it, the soft tubing presses into the bowl to create a tight, reliable closure. No other toilet has this patented technology!

Real customer photo. Real bathroom.

A composting toilet that actually looks good.

Unlike other toilets with pipes sticking out the top or side, the Thinktank vent pipes are hidden behind the toilet.

It blends into your bathroom like a regular toilet, keeping everything odorless, modern, and guest-friendly.
