We have a custom built ceramic tile walls and floor shower in master bath. Drain pipes are cast iron with concrete floor. Built in mid 70's. We would like to take shower out and put in a tub and shower. Would have to be a 54" tub. The problem is what is under the shower and can the drain be moved to meet the tub. I am a do it yourself guy but don't want to get in over my head. Thanks for any help.
