I have an external shower plumbed, the only thing missing is the shower arm and shower head. I will be using oiled bronze hansgrohe valve trim. My goal is to make the arm and head look old/weathered as my area is rustic, the architecture is rustic, and I don't want something shiny/interior-ish to stand out like a sore thumb. I'd rather have the shower not catch the eye - the arm/head will be the only visible component, as the valve trim and outdoor "pan" are obscured by four foot shrubs. I won't use a drain as there is plenty of room for the water to run off and it will benefit the foliage. I'm seeking suggestions for the arm/head. One thought is PVC, and paint it the same color as the structure's stucco wall. Another is brass, another is copper, which I think would patina nicely outdoors. Of course all of these are straight pipes, and I need an angle to direct the shower head flow. Would 3/4 copper with a 1/2 inch threaded fitting on each end work? On the shower head end of the pipe I could solder in a 45 degree fitting. As for the shower head, perhaps an inexpensive plastic one, painted the same color as the stucco? I can always replace it if it does not weather well outdoors.
