Is it expensive to have ceramic tile removed?

Yes it is. Just as it is expensive to have them place into you house, Once the tiles are fixed on to the floor removing them becomes hard and complicated without damaging or breaking them, however if someone chooses to have them removed then it will cost almost the same price or even more for removing them because looking at the methods used to fix them onto the floor in most cases they are meant to be permanent or at least take along time while strong and no space for looseness is left, this means removing them will need more time and delicate work methods that is if you would like them not damaged, but if all you care about is having them removed then it might be cheaper as less care will be put into action while removing them and therefor less time needed and with reduced or say minimal instructions or restrictions the work might be charged at a lower price.
