What kind of pipes? Plastic drain pipe, I'd be careful but just smash it as it sits.

If you have metal drain pipes, I'd pause and do what ever it takes to disconnect.

Oh - and the only critical tip I can share, throw down a tarp or old blanket and only smash the completely covered tub. The email splintera and shatters in crazy directions, from everywhere. It's an absolute pain in the ass. ....but covering it while smashing all but eliminates the blast radius.
