I’ve started on a cob hot tub. Well, the tub is actually a cast iron. I covered it with cob around the sides and hope to build a chimney too. This project has been inspired by Becky Bee’s book “You Can Make
THE BEST HOT TUB EVER!“. It’s a fun book to read and makes you want to start soaking.

The fire burns under the tub and makes it’s way to the flew. It can get really hot… so much so that you need to rest your tookus on a piece of wood. This tub has been left to the elements. It’s been a experiment to see how the cob degrades over time. I hope to finish it soon. I’m considering a lime / clay plaster for the finish.
