concrete board it's not any more work.

Thanks for the reply,
my original question is not clear
I am not putting the tile over the drywall

currently, the cold room only has concrete

I want to put the drywall on the wall
and tile on floor,

I wonder does it has any problem
the cold room does not has any insulation
