The white tiger looks up at the height of the top of the house, not the floor height of the bathroom. At present, the height of the bathroom is mostly one or two centimeters lower than the whole indoor floor, mainly for drainage. However, the floor of the bathroom is two steps higher than the indoor floor. Leaving aside the geomantic factors (upstairs bathroom or overhead downstairs), even from the use point of view, it is unreasonable and should be reformed.
I hope my answer can help you.
