What brand is your shower/tub valve and faucet? It looks like Kohler. If it is Kohler, you can replace the handles with new Kohler handles. Once you decide on your lav faucet, you can use the tub spout and/or shower head from that collection - or find a similar design from another manufacturer. If your current tub spout is metal, be careful in selecting a new one because most mid ranged spouts are plastic. I like your faucets for a mid century bath - they are right in line. The knobs are still contemporary - spouts have changed. get back with your valve manufacturer so we can help you.

I did that in an old rusty basement bathroom, just cut out the old one, and sweat in a new one. You would need to be able to sweat pipes, as you may imagine. Not sure what steps you would like outlined- you have to access the valve body, either from inside the shower (less ideal) or from the wall behind it (more ideal). You need enough of an opeing to cut out the old valve body and make sure the new one will fit in that space, or you would have to do more extensive plumbing. You also will have to address the inside shower wall, and how you will refinish it with the new trim- if you are going from a 3 to single handle, you may well have to add tile... unless you can find one that has a large enough trim to cover the old opening! Which steps do you need outlined?

First, I'd pull one of the stems, take it to a REAL plumbing store and see if they can identity the manufacturer, American Standard, Kohler, whatever. They can probably order replacement handles that will fit your needs. Sounds like your plumber is on the young side. I just got replacements for my 1950's AS. If you wind up replacing the tile (depending on how many you need), you can get 8 full tiles by pulling down the tiles above the shower and just leaving the bullnose trim (that's how mine is and it's original). Patch the drywall and continue the crown molding around the corners to meet the other crown. It looks like pretty standard crown so it should be pretty easy to match. You might also get some extra tile from behind the side panel of the vanity where it meets shower. Just a thought.

Hi, There is a shower repair plate you may want to think about. We called them Stainless steel Smitty plates. a skilled plumber can cut a hole in the shower a little smaller than the Smitty plate. He then cuts out the old valve, solder in the new valve ,mount the smitty plate, install the valve trim over the smitty plate. Done. Good Luck Woodbutcher
