place mapping

So, I'm not exactly sure where to start with this project. The idea is to map the physical and conceptual relationship of a place. I plan on doing the shower (mainly the one that is in the girls community bathroom in my dorm hall). I want to cover the aspects of the routine in showering, the thought process I go through, and the feelings I have while taking one. This has led me to ask the questions: why do we shower? How do I shower and why this way? I also want to explore the idea of privacy. I am in this private stall where I clean and ready myself in private, and think in private. This has lead to the second questioning of: why in private? And where do these thoughts and feelings go once I am finished? Do they get washed down the drain with the dirt from my body?
I am not sure how I exactly want to execute these ideas. I was thinking that I would recreate a shower through an installation. From there I would integrate my thoughts and feelings maybe in cutouts of type. Then I would use a string to attach to each item or word in order of how I take my shower. I would use a clear curtain to cover the whole piece to embody the idea of privacy. Also, I want to incorporate sound by tape-recording myself showering and play it during the presentation.
