FAQ

Common FAQs About Tiny House Toilets

All FAQs
Will my tiny house smell with a non-traditional toilet in it?

Nope! No matter which tiny house toilet you choose, thanks to urine diversion, our toilets don't smell.

Can I use the same toilet from my tiny home in an RV when I travel?

Yes! That’s one of the best things about our toilets: they are portable and can be relocated easily.

Can I compost with a tiny house toilet?

Yep! With Cuddy or Cuddy Lite, you can start the composting process right in your tiny home.

Is a toilet with a sealing option better than composting?

It depends on what your needs are. Here’s an article that explains what a sealing toilet is, and how it compares to composting options.

I have a compost pile: can I really add solids from Cuddy or Cuddy Lite to it?

Yes, humanure is compostable, but keep in mind it takes 6–12 months for the decomposition process to complete.

I already have a Cuddy or Cuddy Lite. Can I convert it to the S1 toilet?

Yes! We have an S1 Dry Flush Adapter Kit made just for this!
