Thanks for the reply. It's a little tricky to get an accurate reading on the window, but it appears that the glass block is set a little off level, although it doesn't show as much on the bottom as it does on the top for some reason. (One part of this bathroom that wasn't entirely DIY
) I do know how to read a tape measure and a level though, and after checking for the 47th time, I can tell you that the surfaces in the opening are square, level, and plumb (Except for a 3/8" slope from the window out to the tub, to allow for water run off). See, that would have been an easy fix. I'd really not rather drop the top piece of Hardi to match the window, as it will mess up the alignment on the tile on the wall above the window.
Anyway, the question still remains - how to adapt the tile / grout / whatever to cover that a bit. I suppose I could split the difference by dropping the right side of the Hardi a tiny bit. But that seems like a cheesy way to do it though... I dunno.
