I don't think tile is any colder (with well insulated house) than carpet or any more dangerous. It's easier to clean. We are sticking with wood or similar because we like it and it's easier to install and because I don't think my kitchen floor will necessarily take tile and concrete board underlay and because it takes forever to special order it. Everyone told me how dangerous it would be to remove the carpet from my stairs. I tripped on it continuously and nearly did myself in on several occasions; I have never slipped on the hardwood. I have a double hip replacement and am oversensitive to flooring: I'd take tile or hardwood any day over the broadloom. We do have good oriental rugs but I never trip on these either. Lucinda
