What I was thinking in my first post, setting a bar on top of tile that may or may not be flat. using a hammer drill to insert some sort of anchor.
It may crack drilling through it.
It could crack when you tighten it to the floor.
It might crack later just from movement and use, leaning on the bar.
It might not crack at all, it just has to many options to do so.
Is several ways to construct a bar on concrete, for me first step is always laying it out on the concrete floor and securing 2x4 to the floor. Then you have many options to stick build it, or add toe kick and cabinets.
But I like to use redheads and liquid nails on the 2x4, crank them down tight for the base.
I built a full bar for a tavern once, stopped by a couple months later to see how the owner was liking it. Was three girls dancing on it, these were not tiny petite girls if you know what I mean. :no:
I said hello to the owner, but was satisfied that it was working fine and all warranty was over.
