I had really wanted porcelain tile for the longest time. I love the look and durablity. However, I spend a lot of time in the kitchen and am getting older so was wondering about the wear and tear on my joints. Plus, I don't relish cleaning grout, it is cold underfoot, heavy, and labor intensive to install.
My grandparents had cork and it was beautiful. However, furniture eventually left dents that would not come out.
I am going to get rubber flooring. Specifically, Nora flooring. It is used in commercial applications, soft underfoot, easy to clean, and I can put "grout" lines in it. I was told that it will outlast my house, which is saying something since we overbuilt portions it.
