 Replacing Bath tub Drain/Shoe
Author: JonH (UT)

Hi All,
I discovered my bathtub drain was leaking. In the process of removing the old drain. it completely deteriorated. It pulled out of the drain hole in pieces, literally crumbling in my hand. I also pulled the old rubber flange out and it was broken and brittle. However, after cleaning everything up, and looking online for a drain replacement, all of the drains have a threaded connection. All of the online self help videos also show a threaded drain during removal and replacement. The thing is, my drain does not have any threads. The drain pipe is just sitting below the bathtub and the rubber flange was sitting in between. I have owned this home for 30 years and this is the first time my bath tub has leaked that I know of. If it had leaked in the past I would have discovered thee water in my basement. That is how I know it was leaking in the first place. How can there be no threads to connect the new drain shoe? How can this not have been leaking in the past? My home was built in 1958. Is this the way old homes were plumbed? Is this something that I can work with?

Thanks in Advance,
JonH

You are not seeing something.

The drain 'shoe' IS threaded.

The tub-side piece may has disintegrated leaving what APPEARS to be an unthreaded shoe which actually COTAINS what is left behind.

You will need to EITHER:

remove the remnants and 'clean up' the threads

OR

access and replace the entire drain assembly.

One possible problem is that the distance between the horizontal pipe and the surface of the shoe is NOT a "standard" measurement, so you have to find one exactly like it, if you cannot save the old shoe.

If it was that deteriorated you probably missed the thread. The shoe that Bernabeu shows goes underneath the tub, then you need a piece like this that threads in from the top of the tub to tighten that shoe up against the bottom of the tub. There should be a rubber gasket between the shoe and the bottom of the tub and then you silicone or plumber's putty under the topside flange like you would a sink drain.
