This was my experience at King Spa.
In the wet area there are three hot tub pools in the center. Each has a different mineral or salts or something, they are usually all the same temperature, 108ish. On the outer walls are the showers on two sides of the wet room. There are sixteen showers with tiny dividers between them. Two of these actually are on each side of the entrance doors with no dividers. So if someone is using one of them, there is a person showering like right there where you walk in. There are also Asian style sit down showers, where you will probably see Korean guys sitting and showering. There are three showers to one side of the door that seem to offer a little additional privacy, being behind large frosted glass. I figured out that the work KING is spelled out in clear glass, giving people looking through it from the other side pretty much a dick's eye view if they want. And, if you are of average height, you can get the same view of people leaving the wet area without them knowing you are getting a peek.
There are oddly additional showers behind a stone wall, typical of what you used to see in high school showers. They are evidently employee only showers.
You enter the wet area naked. Not even a towel is needed, because everything is wet in there. (unless you take one to sit on in the saunas.) There is a wet sauna at 120F. You can barely see more than four feet away. Since it is 100%
humidity, it is HOT. Blowing on your skin feels like fire. There is a dry sauna at 170F. Guys sit on a towel and don't cover (like there would be a point, as I said whole area is complete open nudity.)
There is also a cold pool at around 70F. It has a straight down shower smack in the middle that you can hit a button and stand under. When you stand in the pool, your package is exposed out of the water.
If someone has paid for a scrubdown, a Korean guy will wash them in the wet area from head to toe with some kind of scrubber. They actually will wash your dick and balls, too, from what I understand, and this is done in full view of
everybody.
You cannot put on the spa's cotton shirt and shorts until you have showered, so the wet area is the first visit for everyone. It is complete open nudity in the locker room and wet area.
When I went it was about half Korean, half white, a few black guys. Mostly 30s/40s guys, there was a couple white teenagers and Koreans of literally every age.
