The whole house has been paved with floor tiles, and now I want to add composite wood floors to the bedroom, but I don't want to destroy the original floor tiles. How to solve the height difference?

Cover the original floor tile with a floor, and the floor covered above is preferably 8mm thick. There are two reasons: the thin floor has little effect on the height of the floor (because your room has been decorated and the ceiling has been completed); The gap between the 8mm thick floor and the original floor tile is small. After the floor is paved 1cm with moisture-proof pad. This gap can be solved by universal buckle, which will not affect the appearance and will not have potential safety hazards.
