We have cork floors in our downstairs (main floor) and

it!!! Ours are not the squares, though. Ours are planks and we installed them ourselves, which made it very affordable. We had a major flood and that's the only reason we changed our flooring. The carpet was ruined and the tile was cracked. We seriously disliked the tile anyway. Friends and the various contractor-types gently discussed the benefits of not having carpet anymore. We still liked the "warmth" of carpet and cushioning of the pad/carpet, which is what led me to research cork. I read a lot on the subject before deciding that was what I wanted. I just had to show it to DH & DD and they fell in love.
We got ours at Lowes on Memorial Day last year for a great price and got an additional discount for opening a new account with Lowes and had free financing for a year, which we only needed for a few weeks until the insurance check arrived. I banked the insurance check and let it accrue interest and paid off the balance before the interest was due. We actually paid LESS for our beautiful new cork floors than replacing our carpet and tile would have cost!
