Curve PEX around niche? | Terry Love Plumbing Advice & Remodel DIY & Professional Forum

Are there any drawbacks to running a pex line from the mixer to the shower head like the picture below? What size pex should I use, 1/2 or 3/4? I am redoing the shower on this side of the wall and want to put a niche in where the current shower line runs. Thanks! View attachment 74238
