I am continuing to plan my bathroom remodel... I am planning on removing the tub and tile surround and replacing it with a new tub and tile. I don't see any need to move the faucet/shower head/spout.
I currently have a Moen single handle bath faucet. Shower/tub selector is in the spout. It drips, but otherwise works fine. It would need a new trim kit as the old one is a bit dated and nasty. I'm guessing it is 35ish years old.
What is the better option from a reliability/cost/hassle standpoint?
1. Keep the existing valve body, install a new cartridge and trim.
2. Replace the whole thing.
Not sure if this is a "replace it while the walls are open before it fails" or "then don't build em like they used to" decision.
