It is not the material itself, but the fact that water can leak down
between the seams and rot out the underlayment or sub floor.

Isn't the same true of ceramic tile?

No. Well, yes, depending on conditions and/or the skill of the
installer.

Grout absorbs water. I have a 18 inch
diameter hole in my 10 year old house subfloor that was covered with ceramic
tile and plenty of mud that proves my point.

There's more than one 50 year old tiled shower floor still in daily
use of which the grout has not absorbed water and they are still as
watertight as the day after they were grouted that suggest your floor
suffered a breach of the seal.

And, of course, there's building codes, none of which I am aware
prohibit installing ceramic tile as a shower floor, although I guess
the requirement of a watertight shower pan might suggest to some that
grouted tile is insufficient insurance of watertightness.

Still, if I had my heart set on using a laminated wood product in a
bath environment I would adjust my heart to set upon seamless vinyl
that looks like wood instead.
