I've decided to replace my 50+ year linoleum with tile (ceramic/porcelain). Doing the kitchen first, and to make it more challenging I've purchased 80 sq. feet of mesh backed heated flooring (kitchen is 12x12). I have some 1/8" cork to put on the slab. Have several samples, will probably pick up the tile tomorrow. Thinking 12x24" tiles. Any words of wisdom before I dive into this?
