Gun safe on tile - moisture barrier?

[elg1]

Any recommendations on whether or not a vapor or moisture barrier is needed between the safe and the tile floor (living room)? There will be multiple 3/8" grout lines under the safe. I don't want wood or hockey pucks, or anything that will raise the safe off the floor.

Any thoughts are appreciated.

Just keep the inside temperature above the outside temperature.
That's far more important than any moisture "barrier".

Chances are you will have something beneath the safe anyway. It's very rare to have tile that is completely flat and square, and it is equally unlikely that the safe will be completely flat and square.

If you're going to have to shim it anyway, you might as well shim all four corners. You don't have to do anything tall like a hockey puck. Something thin would be fine.

What is the tile attached to, concrete slab or wood floor? Dry heated air under floor or damp earth? Will the safe be bolted to the floor?

My home is very typical of homes built in Texas that are concrete slab foundation and my safe was placed on a pad of heavy duty porcelin tile that was laid just for the safe because the surrounding flooring was laminate flooring that I thought was not so good for a 1250 gun safe to be basically sitting on for years on end.
As long as your home has regulated heating and air conditioning which practically every home does I cant see any issues at all and have experienced none myself in the last three years the safe has been placed.
In fact I have checked the edges several times for sweating and there is none at all.
And as has been mentioned and that is because tile is laid individually there is no way it will be dead level and some shimming will be necessary even if the safe is bolted down to keep it from slightly moving(shaking actually) while opening or closing the door.

Thanks for the feedback. Indoors is temperature controlled, but I live in a very humid area.

Drail: concrete slab, possibly with a moisture barrier on top of the slab (from the outside I can see some plastic material between the slab and the brick wall). I'd guess the tile is on top of wood decking. Safe will be bolted down.
