Not related to work out, but when I was growing up in S. Korea, public bath was still in use. Most of the houses, even relatively new houses back then didn't have showers.
So, mostly do hand washing with bucket at home, and on the weekends it's the public bath.
You go in naked. There's shower to wash up. Then go in this humongous hot tub in the middle of the place. You soak up for awhile. Then sometimes, you jump in a ice cold water tub. Now, it can't be healthy. Heard stories of old people getting heart attack on occasions. Then there are people who will rub dead skin off of you for tips. You shower again and come out.
Now, if you are a kid, you can go to women's bath with your mom.
