When you say 5" or 6", is that referring to that portion of the trim that fits into the opening (cut-out) in my shower ceiling?A. After re-reading your question, I see that I restated exactly what you asked. Yes, the 5" diameter portion (in this particular case) is what is 'inside' the can. For some reason I misread and thought you had asked about the 'depth' of the trim. My apologies, and regards.
