My answer is based on reading this 120x20 cm, not mm. If mm, you’re talking about a 5”x1” range tile. I’ve not seen that in a wood look.
Use the Deflecto calculator in the blue band at the top of the page. You’ll want a stiff base like a 3/4” or more flooring plywood, but much of the stiffness comes from your joist structure. Start from there and let us help you further once we’ve got an idea of what you’re starting from.
And welcome to the forum.
