Generally, the drain pipe is 50, so you don't need to raise it, just groove it on the ground! If you raise the floor, the floor of the bathroom and the rest of the room will be uneven, and then the floor of the other house will be leveled with the bathroom, and the floor of the house will be lowered and the floor of the house will be lowered. Personal opinion, for informational purposes only.
My house has also changed the position of the toilet and floor drain, and it is all translated within one meter, and it has not been blocked.

Why should the floor drain be raised? If it is raised, it will not be able to flow.
Generally, the diameter of the floor drain pipe is between DN40 and DN50, and the concrete protective layer of 2 cm is at least 7 cm high.
The lower the better, to cover the tube.
The diameter of the sewer pipe is about 5 cm, and the groove is drilled in the ground, and the ground does not need to be raised.
