One thing you did not mention was ventilation?
Be cautious, because in older houses the windows were meant to be
functional.
(I personally pass on
any home w/o operable bathroom windows. Call me old-fashioned. I just don't trust those little anemic fans.
I'm a fan of fresh air and sunshine=nature's deodorizer
)
Edited to add:
Didn't want to sound like such a Debbie Downer.
It's a cute bath. And I know the glass block solution is popular because it adds both light and privacy.
Just wanted to point out that there might be some additional expense whether you go with one of the ventilated glass block systems or decide to go with an exhaust fan to the
outside. Too many DIYers do the cheap thing and just slap a ceiling vent fan in and run it to the attic. Not a good idea.
