Question Where two tiled rooms meet

Hi all, I'm tiling a 300 sq ft room that adjoins another tiled room done 5 years ago. These rooms share a 10' common boundary. Should I treat this as a cold joint (expansion joint) and do anything special while setting backerboard and tiles there or just install like I would next to a baseboard?

I don't WANT to do anything different than use a 1/4" grout line, but I will if I SHOULD. Is it OK to have a regular 1/4" grout line there? Should I caulk the backerboards joint beneath? Or would it be recommended to NOT grout that joint at all because it's a cold joint?

Thank you, Bea

Is the tile going to be the same heighth?Either way i would still treat this as a cold joint and find some colored caulk to match the grout,they make sanded cualk for this as well,or if this is not an option maybe an oak t-bar would work well

Yes they are the same height and thank you - I will use a color matched grout then.
