My bath tub drain pipe I think popped off or cracked because it is leaking into my kitchen and really need to fixx it how can I get to the drain pipe? Without putting a hole in mmy kitchen ceiling ?

There should be a access panel behind the front of the tub. If not you have no choice to:
1. Cut a access panel in the wall behind the front of the tub **OR**
2. Opening up the ceiling.
But wait! You might not have to do either one.
Let's check for a ruptured drain seal.
Seal off the drain or close off the stopper. Fill the tub with a few inches of water and watch the ceiling. If it starts to get wetter drain the tub and get back to me and we'll start a repair.
If the ceiling remains the same then you can open up a way to view the trap and drain line. Good luck, Tom
