First of all, this is not recommended. From the architectural point of view, the waterproofing of rooms is different from that of bathrooms. Installing bath facilities and hand basins in the room will inevitably involve the waterproof transformation of sewer pipes and floors, which will be more troublesome if it is not done well.
In geomantic omen, you add a bathing area in the room, which hinders the overall airflow layout of the room. Just like adding a master guard to the master bedroom of many buildings at present, it seems convenient, but overall it is not desirable.
