Well, where there was room to swing, the sledge worked with one hit to
remove the sill.
The point of my post was that there is not always room to swing a
Perhaps some cast iron tubs are harder than others, but I recall
trying to break up weird cast iron corner shower stall base with a
friend. It took considerable effort. On the sides where there was not
sufficient room to swing - like on the side facing the toilet - we had
a very hard time figuring out an angle that gave us enough force. We

Some of those guys in the Youtube vids shouldn't be swinging a sledge.
But seems it's the preferred way for contractors who do a lot of them.
I think I'd try cutting through most of it down the middle, then see

Of course if I had any problem making cuts, or snapping it, or got
impatient in any way, I'd just pull out the sledge and have it.
We do know that works.
Use a real right angle grinder with an abrasive metal cutting blade.
Did that a while back to remove a bunch of old cast iron sewer pipe
with my tool of choice, a Bosch 9" body grinder. The blade went
through the cast iron like butter, and after a partial cut half way
through, the sledge (5#) did the rest.
Rent the better tool if you don't own one. It should be much safer to
