Large or small ?

900mm ceramics would be a bit of a concern for me, unless they are porcelain, as i'd imagine they would be pretty bowed. I agree with the others though, no reason that a decent tiler couldn't fit them!?!
Travertine would look nice, but is more expensive to fix, so it's really just down to what you want to spend.
3 weeks sounds reasonable, but hard to say without knowing all the job entails. These projects always take a little longer than you think they will, so take finish times with a pinch of salt. 😀

Hi and welcome

I say change your builder, you dont need to skim whats the point waste of money your tiling over anyway , my choice would be to reboard the room in hardibacker so you can hang approx 45 kg psm if the tiles are a large format i would back skim the back of the tile as well.There are some very good tilers on this forum who will be able to help you out good luck.
