I have the opportunity to build an inside shower in a private location right up against trees 2 stories in the air. I would like to have clear glass as two of the exterior walls of the shower making a kind of treehouse shower. This is in the northeast U.S. so they would need to be thermopane glass. Has anyone ever seen this done? I figure it must have been done by someone before but I can't track down or get a handle on the types of windows I could use. I may be over-thinking the problem because it might be as simple as using high quality vinyl clad frames and a clever installation technique.
I'm open to all ideas or ideally a link to a web page showing how someone accomplished this.
Thanks.
