In Jainism, daily bathing is not a strict religious necessity for everyone.

Jain dharma emphasizes:

• Shaucha — cleanliness and purity
• Ahimsa — avoiding harm to living beings
• Self-discipline and simplicity

So, keeping the body clean is important, but Jainism does not make daily bathing a mandatory spiritual rule in the same way for all people. It is generally considered a good hygienic practice, especially for householders.

For sadhus and sadhvis, practices may differ by tradition and vows. They follow a very disciplined way of life, and bathing rules are observed according to their specific lineage and conduct.

In short:

• Daily bathing is good
• Not absolutely compulsory as a universal Jain religious rule
• Cleanliness and purity are important in Jain life

If you want, I can also explain this from the viewpoint of Digambar and Shwetambar traditions.
