It is still sounding like a cast iron tub. A full swing on the
outside of the tub with an eight pound or greater sledge hammer
should shatter it. This thing is going to break more like a piece
of glass than a piece of concrete. It is not going to develop
little cracks that you keep hitting. Same stuff as a cast iron
skillet.

hi guys

I bought a pick axe as suggested by some people here, covered
the
bathtub with a tarp, and tried to break it. No joy. Every
time I
banged it, the porcelain broke off, but there was no sign of
damage
to the metal underneath. What am I doing wrong? Am I not
hitting it
hard enough?

Did it dent at all? If so, the tub is steel, not cast iron.
Cast
iron
breaks, steel won't.


It did not dent, but there were small chips were it was struck.
I
didn't feel that those chips were large enough to cause a crack.

Can I tell from the color whether it is steel? It is a dull grey
metal.


Also, I did manage to cut tub using a metal cutting circular
saw. I did
not get very far, but it did no feel like steel to me.
