    I'm in the process of re-modeling an upstairs bath, and need to relocate supply lines that lie under the sub-floor for a new stand-alone acrylic tub. The sub floor is tongue and groove pine (1.25" thick). From the pics you can see where the old supply lines came up through the floor (these fed a recessed jacuzzi tub that was removed). I would like to re-plumb to the faucet rough-in on the wall. My plan was to intercept the copper supply lines under the floor and adapt to pex before running up to the faucet supply. What is the best way to do this? I've sweated a few copper fittings before, but I'm not comfortable doing this between floor joist, where flame is a consideration. I was considering sharkbites or compression fittings but have heard mixed messages about both (in hidden locations).

    Also, should the outlet box (shown in pic) be moved to accommodate the new supply line location? Thanks!
