The base and glass doors are good, but the back fiberglass is in two pieces that connect from top to bottom, meaning not watertight, and the top edges that rest against the walls (corner) feel flimsy and not able to be secured against the walls so there is a bit of a gap along the lengths -so moisture will get in from there, too.  I should have just tiled the walls and only bought the base and glass doors.  Hopefully it holds up okay, long enough until I can redo it.
