How do i install ceramic tile over existing wood flooring?
Ceramic tile MUST be firmly attacked to the subsurface so don’t go with your first idea. Your grout will crack and the tiles will pop loose doing this. The second idea should work if you screw the backer firmly and at the recommended spacings, but it will ruin the wood floor. My opinion: It’s rare to see a wood floor in a kitchen, at least I don’t think I’ve ever even seen one! Most people aren’t going to be looking for a wood floor in a kitchen when they’re looking at houses. There is a product now that is a laminate tile. It is basically the same as laminate wood flooring, but it has a tile look to it instead of wood. Laminate floors usually float over the subfloor and are not attached anyway. This might be an option, as the laminate tile could be removed later with no damage.
