I've got tiles in my kitchen and underneath said tiles there's just cement so the entire kitchen feels like I'm outside in the winter. It's hideously cold in there and it doesn't seem to retain heat either. Can't afford to break the floor and put underfloor heating in but need a temporary fix for atleast a few years. So far as options I've either got fabric tiles or foam mats (the kind used for kids or for home gyms). Don't want a rug or carpet as it'll be harder to clean with little kids around. Are there (hopefully) any better ideas to keep the kitchen even slightly warmer?
