I have removed the back of tub and pulled out the whole thing... I have removed the drain cover.. when I remove it there is a metal x then under it there it is a solid metal like bowl around, in the back of that metal bowl like thing is a hole... I have cleaned it all out, used draino, plunged and it still won't drain. Any suggestions?? I'm a single mom and strapped for money, so trying to fix it myself.. I'm pretty handy fixing things, but this has me stumped. Thanks Lori

Let’s try 1/2 cup baking soda 1/2 cup salt mix it pour it in the drain and add one cup vinegar leave it overnight, in the morning pour a bucket of very how water and turn on your tub faucet to flush out every thing see if it drains good now, if not you have to remove the trip liver (face plate) the plunger and snake it see the images below, good luck.
