I hate to pile on, but that's why it was always a bad idea to put a
hardwood floor in a kitchen, at least since linoleum was invented.

I said so years ago when I first read about it.

Maybe in up to the 1800's when there was no choice, but I think then the
floors might have had cracks that would drain the water through, so it
didn't soak the wood so much, or the boards were thicker and much less
likely to warp.

Ceramic tile is also a bad idea because it increases the odds that a
dropped glass or china item will break.

It probably wouldn't help if a pipe broke but a slow leak would be
caught with one of those raised lip trunk liners if you could find one
the right size.
Hopefully you would see it filling up with water before it overflowed.
They do make water sensors you can put under appliances like that to
alert you when there is a problem.
I think it is just a CMOS gate with a printed circuit grid that shorts
out an input if it gets wet.
