I would really suggest to get a new shower. I guess you already know this but because there is no shower walls the water goes everywhere if you stand up to shower. The main option is to sit down and shower but the shower head leaks so you find yourself sitting in a shower with limited water because so much is leaking from the connection. I knew about it from last year and I appreciated that you had put towels on the bathroom floor but that would be my biggest tip.
Also, there is a large broken sliding door towering next to the bed, which is in a tight corner; so the only way to access the bed is from the foot of the bed.
