The new bathroom tile in my house started cracking after just two months

We used a thin-set mortar that was supposed to be good for large format tiles, but I think the subfloor wasn't flat enough. Now there's a hairline crack running right through three tiles by the shower. What's the best way to fix this without redoing the whole floor?

You mentioned the subfloor not being flat. I used to think you could just replace the cracked tiles, but a contractor friend told me that never works long term if the floor underneath is the real problem.

Your contractor friend is right, @morgan_jenkins90, as I learned after my own "why are these new tiles also cracked" moment.

Whoa wait, the thin-set mortar was supposed to be good for large tiles but you think the floor just wasn't flat enough? That's a brutal combo, sorry you're dealing with that.
