Your post gives me encouragement that this floor might not glued down after all, and I might be able to easily take it up and replace it with something else. Yes, SW Florida but I really don't want tile throughout, even if it looks like wood, because it's so hard on your legs and back. Still leaning towards cork planks...
If you know the difference just tap on the floor and it should sound hollow but not many consumers cannot tell the difference just because wood always sounds a little soft.
I'm a big cork fan myself and install it floating and glue down. The glue down cork tiles do not give as much as the click planks but after your done and apply a finish the stuff is dern near bullet proof to minor water leaks. Plus glue down can be made into patterns or just about any design you want with different colors.
But glueing cork can be touchy, ya gotta be experienced.
