The duplex downstairs sunken bathroom is generally poured together with the bottom and top and the wall, and it is difficult to separate them instead of laying bricks on the floor. This is also the reason for the high safety factor of the earthquake shelter toilet.

It's not cracking of the floor slab. It is the newly made cement mortar that is not well maintained, and the cracks caused by it generally do not affect the quality.
