Thanks so much, I do have some left-over copper stub outs. Didn't realize that strapping them to wall was an option, that seems like the way to go. I want to keep at least 3/4" insulation between the pipe and block wall, but the bend radius seems tight enough that it should be fully straight...

I also just got the specifics on how much of a bottleneck the valve itself will be. Kohler says 5-6 GPM through the valve, which diminishes some of the value of 3/4" PEX, but to maintain 6 GPM using 1/2" PEX (assuming the mixer is basically set to full hot) would require 10.86 fps velocity...

Absolutely, I was only using the bathtub/shower in my second bathroom as the basis for comparison. Master bathroom has just a shower but the second bathroom has a shower in the bathtub. When first turned on, the water spews out of the bathtub faucet at an unrestricted rate (limited only by the...
