This
 is a huge water park/hot springs, but I only visited the hot springs 
park. Admission is 8000 w for the hot springs only, but quite a bit more
 expensive for the rest of the facility (33-39,000 depending on season/day of week). I got there at around 8 am, and
 it was very quiet, there were only 3-4 other people in the sauna.
 By the time I left around 11, buses of schoolkids and older ladies had 
arrived and it was quite crowded! 
 The locker 
rooms are massive, and plenty big. There are a ton of showers, but I 
found them sort of cold. The baths here are great- hot tub, huge warm 
tub, laying down massage tub, some sort of massage tub with many strong 
jets and bars hanging over it (I didn't quite figure out the bars, do 
you hang on them?), there are ginseng and green tea baths, a really hot 
steam sauna, and 2 dry saunas, one with a TV inside! There is also a 
stone area to rest on, which feels great. The outdoor part is nice, too,
 with a hot hinoki and a cold bath. The water is great hot springs 
water, your body will feel very nice after soaking in it.

 whole facility is very clean and well maintained, my only complaint was
 no food at all available.There was one vending machine with canned 
drinks, but that was it.
  Since there is no jjimjilbang, you must get all the way dressed to go 
out to the on-site restaurant, and since normally water-park restaurants
 aren't very good, I just decided to leave. If there had been some food 
or snacks, I would have stayed longer!

Near the entrance to Asan Spavis is a great Kalbitang restaurant. I went 
alone, so I didn't grill meat, but it looked good, too.
