Original ground is ceramic tile, shall we remove the tiles to install PVC flooring?

Answer: no need to remove it. If it is PVC flooring tiles/plank, you only need to do a simple treatment at the seam among the tiles, then install the planks directly on the tiles; If it is PVC flooring roll, you can do a layer of self-leveling concrete directly on the tiles, then do install the flooring roll. The noise is small during installation. Installation is easy and fast.
