I'm looking at unglazed porcelain (not ceramic) tile flooring for my kitchen. From the research I've done, unglazed is apparently a bit more resistant to chipping or cracks and/or chipping or cracks won't show as much. The only thing that concerns me is possible staining. I did read in a few places that modern unglazed porcelain tile is so non-porous that it doesn't absorb stains, but I'd like to hear from people who actually have this type of floor to be sure.
So, do you like or hate your unglazed porcelain tile floor? Does it stain easily, and is it a pain to clean?
