I don't know personally, so I would contact the person who posted the photo and/or contact a doors specialist and ask them where you can get that one, or similar.

So far I have only found it with a raised panel instead of the Shaker style but I'm sure they are available. You have to specify obscure glass. It will be a special order and you'll have to decide if you want steel or fiberglass.

Go to a good lumber yard. It isn't going to be off the shelf. Have them come and look at the threshold, all of it. It's EXTERIOR, not a closet, and it isn't just a case of order a door : ) Nor is the install.

I agree that going to a proper door company seems like the best (although no necessarily cheapest)bet

If you check HD they have catalogues full of doors that do not have on the floor, we got all our interior doors with pixelatated glass from HD no issues after 12 yrs. I have an exterior door in steel with that size glass and just a different design on the bottom I an pretty sure this would be available
