My single handle tub/shower faucet in the upstairs bath needs replacing. I have a vague understanding of water supply and faucet replacement when it comes to bathroom and kitchen sinks. For one thing they have shutoff valves, as do commodes. However I feel way out of my depth on this project. The water supply to the house will have to be turned off, then there is the problem of access. This fixture is coming through a fake marble surround, probably about a 6" diameter hole. Can everything be done from "this" side of the wall? If necessary I can actually get to the back of this setup, I climbed into the space behind the tub and saw copper pipe leading to it. Someone had slapped a 2x6 over this area but I could pull it off if I have to. Any experienced plumbers on the HTF that can give me some guidance? I'll almost certainly hire someone for this, espcially if sweating copper is involved. Mostly I wanted to know if it can all be done inside the room. Thanks, Jim Also asking for recommendations for a replacement: Moem, Delta, American Standard etc.
