best ways to smash up a cast iron bath?

[Kyle87]

I cut one in half today. 3 cheap 1mm 4,1/2"cutting discs and job done. Smashing it to bits just seems like too much effort.

always hit sideways not straight down

Knock outwards down one corner and break into 5 pieces. Two ends, two sides and a bottom.

Wouldn't want to use an angle grinder on it.
