Well-being Land is a very nice, new jjimjilbang in Buk-gu, Daegu. It has many rooms and a nice sauna area with a variety of baths. I haven't been there in a while, but I remember being impressed. The sauna, jjimjilbang, and screen golf are open 24 hours!
You can find this sauna easily, by walking out of Palgeo Station exit 2. About a block and a half up the street, you will see Well-being Land on the left. (It's not far from the HomePlus in Chilgok.)
