This worm farm is a wonderful reuse of an old bathtub. I especially like how the drain was plumbed for serving up that rich, fertilizing “worm tea”. My wife and I did some worm composting a few years ago in a much less attractive plastic bin. Next time we’ll build a stylish, bathtub-based worm mansion.

  • Really?

    I thought old bathtubs had enamel to begin with. So painting with what kind of paint would make this safe?
