Smashing off just the top row will not help if that row is not level in the first place which to me, it doesn't look like it is. (Unless the window is out too)
The tiles are level....the window is out. The original tiler noticed this but just ploughed on instead of asking me my thoughts. Plus this way I will get rid of the worst lip in the whole bathroom which is between the top row and next tile down.
