Window in Shower. What would you do?

[Bill Sargeson]

I have a foreclosure that I am seriously considering buying for a rental. My concern is the bathroom has a window in the shower.  I was planning on gutting the bathroom and doing a complete remodel.  I thought I could put in a glass block window during the remodel.  You can see from the pic that there is water damage around the window(wood frame with a vinyl replacement window) plus who knows where else. I don't have any houses with a window in the shower so I am asking for input for those who have experience with these.

Thanks!
