Bath tub drain replacement?

I tried to use pliers to unscrew the drain but it was so coroded that the crossbars just fell apart. So I tried to loosen it from around the tub and the drain pipe separated from the tub. Can I fix this without taking the whole tub out? If I have to call a plumber, how much does this usually run? Thanks in advance.Bath tub drain replacement?
Which type of drain have you got?

There are actually 2 connections with a tub drain...


1) there is the plumbing connection itself, where the drain directs the water into the house plumbing....we need to know if youve got plastic or metal drain pipes. If it is plastic...it is possible the drain is actually glued together... which means you'll have to cut it apart.


2) there may be a locking nut on the bottom side of the tub, that holds the drain in place...its easier to take this type apart from UNDER the tub.





Next question is what is under the floor? Is this tub over a basement, crawlspace, or living space? Is there an access panel (sometimes located on the other side of the wall).Bath tub drain replacement?

We don`t all have the same house and live in the same area. Can you tell us what floor the tub is on? If its the main floor , do you have a basement? If not is there an open area on the other side of the wall the taps are on that you can get to and cut a small 12';x !2'; section of the wall out near the floor? That will give you acess to the bottom of the tub. Go to Home depot or Rona and most of them will give you an idea of what to do and where to look.
When you replace the drain on the tub, you would have to seperate the drain pipe from the tub. Usually you have to go into the crawl space to do it. You have to put the fitting around the drain pipe, screw it into the drain coming out of the tub, and tigten it down.
