Changing from one brand showerhead/handle in shower
I have posted this on the plumbing site but thought I would try here as well. I am looking to change out the showerhead and handle in my son's shower. The brand I would like like to switch to is kohler. Can this be done without ripping out a wall to change the valve. I would ask my plumber but he is on vacation and wanted to place an order soon so that when he returns, I can have it installed. If anyone can give me an answer I would be so appreciative.
