What is the ruling on praying on the floor of a house that is walked upon with sandals and shoes, and is entered into the bathroom with?

Prayer is permissible on anything whose impurity is not known, based on the saying of the Prophet, peace and blessings be upon him: "And the earth has been made for me a place of prayer and a means of purification." Therefore, one may pray on tiles and other surfaces. The fact that people walk on it with shoes does not necessitate refraining from praying on it, unless the impurity of the shoes is confirmed. The original state of the toilet floors found in homes is purity, because impurity is confined to its known place. If the worshipper is certain or predominantly believes that there is impurity on the bottom of the shoe that walks on the tiles, he should not pray until he pours water over it.
