What is the ruling on praying in a prayer room that deviates from the Qibla, and whose walls are affected by water from the washbasins located behind the Qibla wall?

The place whose purity is stipulated for the worshipper is that which the body or clothing touches. As for impurity that the worshipper does not touch, it does not affect the prayer. It is not permissible to deviate from the Qibla due to the presence of a trace of impurity on its wall. Rather, one must face the Qibla, and the prayer is valid. It is advised to repair the wall or pray in another prayer area. A slight deviation from the Qibla does not harm the prayer, but a major deviation invalidates it.
