Installing the narrowest Kohler frameless ‘falling rain’ glass door

Hello,

Your blog is the best out there. I am learning A LOT!
I saw these 2 pictures and have questions.

I would love to do this but I think making 2 “windows” in the wall and installing the narrowest Kohler frameless ‘falling rain’ glass door on the angle opening -will be a lot cheaper and much easier on my tile man. Not as pretty for sure! But would you hazard a guess as to what I might save going that route (I would have two tall support columns on either side of the door, correct?).

My layout has a vanity where your door opens into. Otherwise very much the same is planned (not started yet). To complicate matters, I am in AZ for months and my contractor and house is in NY!

Appreciate your time! THANKS!

Sandy
