In response to Re: Convert bath/shower drain to shower drain
: i have a ruff in bath/shower drain of 1 1/2" in my basement but want to chnage this to a shower only. would the 1 1/2" work or do I need to bust up the concrete and replace with 2". I'm at the stage of finishing the concrete shower pan and really do not want to bust up the concrete. I'm about 4 feet from the main drain.

: What can I do?

The correct way to do it would be to open the cement floor as needed to run a new 2" drain for the shower. If you connected the 2" shower drain to the existing 1-1/2" drain pipe, it would probably work but it is not a legal plumbing connection and could possibly lead to standing water while showering or repeated clogging.
An inspector would fail the job if it were filed and inspected.
