and asked about the shower as I had heard about it vaguely in past. She just told me to go to the Sheraton; no pass, etc. I went there and asked at check in and they signed me in, gave me a key, instructions, and a time limit. (I was taking the train onwards to another destination in France and actually not going home for a shower after my flight)
I don't know how easy it would be for someone who is unfamiliar with CDG and who doesn't speak French ie if they want to take the risk of just showing up, but if one is taking the RER into Paris anyways, it really isn't a detour to go and ask.
Your experience is the only one I have heard of. I would think if this were truly available to all UA C and F passengers arriving at CDG as you said, there would be a report from at least one of the more than 100 that arrive each day. More likely your GS status worked that time, or you just got lucky.
A reliable way to shower at CDG on arrival for C and F UA passengers is to go to the Star Alliance lounge, which is inside immigration using the elevator near the duty free shops in T1. The problem in doing so is that if you have checked luggage, it will be outside immigration, spinning around on the luggage carousel. Or worse.
