Rabbi Baruch Bodenheim: Gemara Shabbos: Perek Kirah, יום חמישי, Tamuz 28, Daf 39b-40b – Bathing on Yom Tov (07/24/25)

Bathing on Yom Tov 

Can one heat water to take a luke warm shower? 

Learn שער הציון ס’ תקי”א אות כה 

When one opens up the hot water faucet on Yom Tov, is the water which comes out considered heated before Yom Tov?

Learn שמירת שבת כהלכתו פרק יד הערה יב 

May one open the hot water tap to take a lukewarm shower which allows new cold water to enter the hot water tank – effectively heating it up. Is it considered heating up the water to bathe ones entire body or heating for permitted use as the water in the tank is not designated for specific use and will be used to wash dishes or wash one’s hands?

See Celebrating Yom tov from Rabbi Hershel Welcher Chapter 3, footnote 46 below

Does the minhag not to bathe in cold water on Shabbos also apply to Yom tov?

If yes does it extend to showering?

What’s the halachic conclusion regarding bathing on Yom tov?

Is it ever permitted and if so in which way?

According to the Mechaber?

According to the Rema?
