Congrats on your QS8's, Greg, they are great little speakers. Checked out your HT project, looks very professional and thought out....as such, I would vote for the shower doors. You've done such a great job so far, I don't think you should skimp on using curtains, doors would look more professional(like the rest of your project) even though curtains would be the easy instal.

Half of communication is listening. You can't listen with your mouth.
