I agree that the Hans sauna is not decorated with any kind of theme in mind, hence the lack of atmosphere. The public areas are bright and clinical looking. However, the new Hans is a much-improved version of the old, grungy Hans. Actually, it feels like a completely different place; even the clientele is different. While most patrons are 30-40s, there are quite a few younger ones as well. Overall, it is not as crowded as Soi 13, but there is plenty of action. I have a good time when I go there.
