What is your verdict on taking a bath in a closed bathroom naked? What about performing ablution after taking normal bath, is it accepted if done naked?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

It is permissible for a person (whether a man or a woman) to take a bath naked in a closed bathroom not seen by others, because covering the private parts of the body is not a prerequisite for purification.

For more benefit on the nullifiers of ablution, please refer to Fatwa 84093.

Allah knows best.
