There are many regrets after the transformation. Can the wooden floor be changed into floor tiles?

In general, the floor of the bathroom is generally lower than that of the living room, that is, the floor of the living room is higher than that of the bathroom including the balcony. If you replace it with a floor tile, the difference is1.5cm. Although it is a little more, it is normal and possible to be around 1 cm. But if the floor of the bathroom is higher than the living room, it is best not to change it, because once the bathroom is flooded, it is easy to flood the living room.
