I'm re-doing a shower. I have 1/2" PEX supply lines (hot and cold) coming into the bathroom. This currently coverts to 1/2" copper to a single valve and shower head.
I want to leave the 1/2" supply in place, but replace everything else. I bought all Hansgrohe valves and heads. The valve has 3/4 NPT threaded ports, and the heads have 1/2". I'd like to use PEX, because I figured it'd be easier. Since the valve is 3/4", I bought some adapters to go to 1/2" crimp-style PEX. Diagram is here.
The tubing looks small, and I understand it has a smaller inner diameter than the 1/2 copper.
Should I go with 3/4" PEX instead between the valve and diverter and b/w the diverter and heads, then downconvert to the 1/2" at the end fixtures? Or, is 1/2" Ok, given that I'm planning to keep the supply lines? FYI, I'll have a handshower, regular shower head and a rain shower (I realize I won't be able to use them all simultaneously). What would give the best result with the given supply lines and valves?
Here are some pictures - I appreciate any advice you might have :
Supply line:
The current setup, with compression fittings between 1/2" PEX supply and 1/2" copper:
The new Hansgrohe valves with sharkbite coupler (which I'll use to connect supply to new 1/2" PEX), and the adapters (3/4" NPT to 1/2" PEX crimp-style, not compression):
