Travertine on the vertical surfaces, slate on the floor.

Should I set the walls first and then fit the floor? Or vice versa?

What is the preferred method, and why?



Depends on how you finish off joins. Most often the finish (baseboards)
go on the wall, so you finish the floor first. Your floor could/should
probably extend beyond wall, with travertine down to it, then - caulk
joints?
