Q: Is it possible to lay wood flooring over ceramic tiles? What are the pros and cons if any?
A: The first question is how will you secure the floor?
Any floor will be as secure as the foundation it sits on. You are far better off, in spite of the work involved, to strip everything off to the original subfloor, screw down plywood if needed and then install your solid hardwood on top of that.
Related Q: I want to install a floating wood floor in my kitchen, but I don’t want to remove the tiles. Can I lay the wood on top of tile? And if so, what do I use to fill in the grout area so that it’s level?
A: I don’t think the grout lines would be a problem. Just install the recommended foam padding first.
