Sorry this question being asked again but should floor be done first or after. My thought is if we move we can take the bar with us if the floor is done underneath. But now we are being told that the meaning of floating floor is it needs room to move. So we are now being told to do floor after any cabints are done. What is the difference of a cabinet versa your furniture on the floor?

Thanks for you help in advance.

If that bar is just going to sit in place and not be fastened into or through your floating floor, then I do not see why you cannot place it on top of the floor. Realize that one should not anchor anything down to the floating floor. If you have plumbing or electrical going to that bar, then code will probably require it to be fastened down in which case, you should not install the flooring under it. Besides, there would need to be holes cut into the flooring for the electrical and plumbing anyway. But a heavy piece of furniture like a bookcase, isn't much different than your bar. Both can be placed carefully on a floating floor as long as the furniture is not fastened to the floor.

If it weighs enough, it can potentially bind the floor. However, the reality is that the admonition against putting cabinets on top of floating floors stems from a generally held assumption that the cabinet folks are going to screw them to the subfloor just as a mater of habit.
When looked at in terms of static load measured in psi, your bar will have a lighter footprint than a china cabinet and certainly less than something as heavy as my upright grand piano.
