It's actually not quite flush, there is a very small overhang of maybe an inch or less. But yeah, I am kind of wishing there was a little more length there if for no other reason than actually finishing that corner is turning out to be awkward. I'm mulling whether to do a thin corner strip of water barrier or something. There will be a shower glass (
specifically this one) but a small amount of water is inevitably going to get under or around it.
