On my 32BHDS the tub surround has a gap on top and is not sealed on the bottom where it meets up with the bath tub. I have been told this is designed that way to allow any moisture , behind the tub surround, to escape. The top lip of the bath tub extends a few inches up the wall and is overlapped by the tub surround.
