This 1952 house with still nice tile showers and real plaster walls could do with a modern mixer valve in the shower in place of the old hot/cold valves it has now.



I can get a couple of smitty plates to cover the old holes in the tile. The problem is the plumbing behind the tile. Threaded steel pipes and some bronze fittings. Can I change that to a mixer valve without tearing up the plaster and the tile?



The new plastic lines and valves went in last year, and we left the wall open for the project we're facing now.

Appreciate your comments.
