My partner and I love to visit spas and hot springs when we're in Europe. She enjoys getting massages, while I prefer to relax by reading a book or just soaking in the water. We're planning a trip to Thailand and we were wondering if there's something similar in Bangkok that's adapted, of course, to the local temperature. We don't expect there to be hot pools, but rather a kind of spa where I don't have to wait awkwardly in an uncomfortable chair while my partner gets a massage.
Just to clarify: I'm looking for places like Therme Erding where massages are complementary to the stay. Places where you can spend a whole day relaxing here and there.
