How hard is it to replace a tub/shower faucet? The handle is broken (see picture). Do I need to replace the entire assembly? Since I have only a limited size hole in the tile, do I need access through the wall behind? Is there soldering involved? The house was built 13 years ago.
I would find out what brand the faucet is and go to a plumbing supply house and get a replacement handle. This not a rare problem, so you should be able to get the part. Replaceing the faucet entirely could cost a few hundred dollars. No need to tear up your wall and solder on a new expensive fixture if all you need is a handle.
I would pull off the handle and try to figure out what brand it is before you bring it into the supply house. hopefully you will get a patient person who will find it in his books.
Well, now that's the problem. It's a Delta. But I have pushed and pulled, twisted and tapped (all the while of course looking for hidden screws or removable covers) but I'll be darned if I can get the handle off. I can remove the little water temperature adjuster on the front via the screw down the center; but I can't get off any more than that.
