I am installing a outdoor shower on the exterior wall of my house to go with my new pool deck. I have a built-in grill that has an enclosed cabinet underneath.
I have a way to run a hot water and cold water line for the shower, but I would like to run this line through one exterior wall into a cabinet area for my grill and then out the perpendicular exterior wall to the shower (see image it'll be clearer).
My question is this: that water line will probably be only six inches from the grill and the grill obviously gets hot. I'm thinking CPVC will not work because it would melt, but would copper work? Should I do some sort of insulation to try and block the heat and if so what?
Oh and for clarity – obviously I could just run the pipe alongside the entire exterior of the wall around the corner, but my wife would prefer it be "hidden" if possible hence the question.
Thanks in advance!

If it's going to get that hot in there you should be insulating the pipe regardless. Foil and fiberglass would do.
If it gets hot enough to damage pvc with water in it you have bigger problems. Have you ever seen the styrofoam cup with water experiment? Granted, you don't want the water in the pipes to be the only thing saving your pipes, but if the space inside the cabinet gets hot enough to melt pvc you're putting your entire home (and its occupants) at risk.
