Adding pressure alanced shower valve.

honestly its a big job, with two baths back to back i would hire a plumber. me and my neighbor just replaced mine, it took a good 10 hours, and lots of hassles. back side inside a closet, inconvenient but doable

much better than pressure balance is pressure temperature with flow control. bought a delta, no matter what it holds temperature within 3 degrees.

money well spent.

a experienced person should be able to remove the tiile with minimum breakage, could you steal some from say under a sink for repairs?

Getting to the valve is the hard part. Actual replacement takes a few minutes. If you are comfortable removing the tiles, then go for it. I hung a mirror on the wall where I had to cut it out.

t. =EF=BF=BDI hung

do note if new valve replaces old 3 handle valve things may not line up well, and valve must be solidly anchored you cant depend on tile wall to support valve without another mount spot

A couple of years ago on Ask This Old House they did that. They used a valve that came with a large cover plate to cover the hole you had to cut in the tile.

tile can be removed without breaking, i have done that myself.
