I loved this place! I have been to a number of similar places in Europe and Asia, and this one certainly measured up.
It seems like a lot of people are hesitant to go because of the no-clothes policy in the pool area. I will point out that if this is the case, there is still a lot you can do in the clothed area, which includes a number of dry saunas, a relaxing area, and the restaurant. As long as you enjoy saunas, I think it would definitely be worth it to go even if you just stay in the clothed area. You can always check out the pool when you get there if you feel comfortable with it.
When you arrive, you pay $35 (although I think it's going up to $40 next week) and you are given a spa outfit of a t-shirt and shorts, and a key to your locker that is also used to record anything additional that you buy, like drinks, food, massages etc. Then when you check out you pay for the additional items you bought. The admission fee lets you stay for up to 24 hours (they are open 24/7) so you can spend as much time as you want.
There are two main areas to the spa - the common area, in which genders are mixed and you have to wear the outfit you are given, and the gender-separated areas. The common, mixed area includes a number of "poultice rooms" - really dry saunas - that each have a theme such as salt, charcoal, or red clay. Each theme is supposed to have a certain healing power. The rooms do not have benches like a European sauna, but mats on the floor that you lie on. The common area also has a bunch of mats on the ground where people rest, hang out, read, etc. There are a few tv's, a refreshment stand, a fitness room (including "body shakers"!), and a restaurant that serves delicious Korean meals. The meals run about $9-12 and include a number of the traditional side items like kim chi.
The gender-separated areas include the very nice changing/locker rooms and the bade pool area. In these areas, no clothes are allowed. The spa does provide towels, but they are quite small (think hand towels) and don't provide too much coverage. I don't think you are allowed to use your own towel. I found that after a couple of minutes, you didn't even notice the nakedness at all and it just seemed normal. Anyway, the bade pool is great!! It is a warm-ish pool that has lots of different stations with water jets to massage various parts of your body. There is also a steam sauna, dry sauna, cold bath, and several hot tubs. These are all surrounded by shower stations. The spa provides pretty much everything you need - shampoo, conditioner, hair dryers, even brushes (a little gross if you ask me). You don't have to wear shoes (most people walked around barefoot) although I did see a few people in flip flops.
Overall, I thought it was a great place to spend a few hours and relax.
