OK...I'm sure these guys believe what they are saying...but they are discussing FLOATING FLOORING. That is sitting on HDF (fibre board). The WATER PROOF stuff is 100% cork. It is 4mm - 8mm thick. There is nothing but cork...cork...and then some cork. Nothing in the middle. When people say that cork isn't good with water, I always ask them: What is in wine bottles? Cork. What is the material that kept the Titanic's Champagne 'sweat' (ie. now salt water intrusion)? Cork. I'm not kidding. Google the sale of Titanic Champagne. It exists...and so does the CORK that kept the sea water out (at 3800m = 12,000 feet). Cork is glued down to the subfloor. It is butted tightly together. Then a polyurethane is applied over top = water proof. You can spill GALLONS of water on the floor and it will sit there. The cork does nothing. It doesn't care. So long as the water does NOT reach the walls or the cabinets you are fine. This is IDENTICAL to stone. This is identical to porcelain. So long as the water does NOT reach the walls, you are fine. Just suck up the water and go. Cork is the same. Whosoever 'poo poos' cork's water proof properties does not know the REAL cork flooring. The CLICK together stuff is a different animal and it needs to be TREATED as such. I can get a floating cork floor in a kitchen. No problem. How? Because I know what I'm doing and I know what I'm dealing with. Am I an installer? Nope. Just a sales chic! But I've done it, personally, on several occasions. I can also install a decent glue down cork tile in a BATHROOM. Yep. Baths, kitchens and entranceways = super happy places for glue down cork tiles. But cork is expensive and takes +++ MONEY to install (if it is glue down). So the cork industry tries to make it easier to install....but the SALES people (and many installers) fail to understand the product and they FAIL to follow installation/maintenance instructions. I can get the softest wood floor (cork) to be water proof (glue down tile) and to be the toughest floor you will ever meet (Loba 2K Supra AT applied x 2 coats after installation). But then again, I know what I'm doing; I know what I'm working with and I UNDERSTAND what cork is. I think you would be hard pressed to find the same with the Gents in the video. As for resale, the EXPENSIVE cork glue down tiles = as valuable as marble flooring. Nope. Not kidding. But then again, I understand cork.

What did you end up choosing ? I am considering lato from flooret or calypso from coretec

I have Coretec (Noce travertine) and it is very easy on the feet as well as extremely durable. We have had 100-pound dogs and wet/muddy boots all over it, and it withstands all of that well. I can't speak to the other brand. If you heard that Coretec lifts up, I suspect that "lifting up" is a sign of an uneven subfloor. The installation instructions include a standard for variation in floor height. My contractor did use a LOT of leveling compound in my old house to get the subfloor (mostly) level before installation.

If flooding was an issue, I would not replace with another laminate. Laminate is made from wood particles and is NOT waterproof or easily repairable. Vinyl would be the better bet, as it's waterproof because it's entirely manufactured. As for the color, it's really preference. Red wood can look very red in certain lights, so make sure you have ample natural light for that one!
