Baden, 35km southwest of Vienna, has been known for its thermal springs since the Romans ruled the area, and during the days of the monarchy, such prominent figures as Mozart and Beethoven were known to frequent the spas. The building itself is beautifully designed and the pools, heated at different temperatures, are a soothing respite. The sauna area is extensive and costs more, but is worth the extra couple of euros. Furthermore, the massages are professional and just may be the icing on your cake.
