Is facing the qibla necessary for ghusl and wudu?

Is it mandatory to face qibla for ghsul and wudu?

Facing the qibla when performing wudu is a Sunna, but it is not obligatory.

As for facing the qibla when performing ghusl, there is no evidence for this being a Sunna, therefore it is neither obligatory nor recommended.
