Bath tub drain kit and main drain reducer HELP!

This is part of the drain and overflow 1-1/2" pipe for my bath tub, I needed to replaced the rubber reducer, which is 3" at the base, I found this one, which goes to 1-1/2" but I think it's made for the black plastic pipe which is thicker. I have not seen this reducer sold in a reduction to 1-1/4" which would fit the 1-1/2" white pipe. So...

Question is, use what's here and somehow make it work with extra parts, if so, what?

Or get a different bath drain pipe kit that's not the white plastic?

This is holding up my entire bathroom renovation, help!

You should have a trap in the tub drain before you transition to a larger size pipe. Are you connecting to PVC, cast iron or copper pipe??? If PVC then I'd use PVC for the trap and glued reducing couplings for the connection.

Thanks, this is the cast piece in the ground. Before it had a rubber reducer on it like the one shown, then a metal drain pipe kit, but was very old and rotted away. Im not sure I understand what to do yet, I was replacing it as it was before, not sure if it was correct before?

This is the ground main drain, cast iron I think, where the rubber coupler was before.

Hi, The adapter you have is for 1 1/2 pipe. The tub drain is 1 1/2 tubular ( smaller outside). I have used a fitting like that except it was 1 1/2 pipe by 1 1/2 tubular. May be you can find an adapter the right size. You also could get a male threaded adapter and put the treads in the rubber adapter and tighten it down. If the treads on the adapter are not long enough to get a good grip use a 2 or 3 Inches of 1 1 /2 ABS, glue an adapter on the end and put it on the rubber adapter.
Good Luck Woodbutcher

Thanks, I hit up a pretty cool plumbing shop tonight and they hooked me up with the black plastic adapter, it worked perfect. The only issue now is, it brought my waste shoe up about 1/2" (give or take) so it's at an angle/ pitched. The tighter gap is towards the faucet, Im not sure if tightening the drain into the waste tube will work, it may flex a little bit. Anyone seen this? I don't want to tighten it with my tubewrench it may screw it up. My guess, probably get back under here and maybe cut the spacer or find a shorter one.
