Hotel saunas in Spain?

My wife and I will be travelling to Spain next year, and a friend of hers will be joining us. After a long day of sightseeing, we always like to spend some time relaxing in the sauna at our hotel. In the US, hotels will either have seperate mens/womans saunas, or have a coed bathing suit required sauna. We have heard the in Europe, nude coed saunas are common, and in fact used some of these in Germany. Is this true in Madrid and Barcelona hotels? Normally, we wouldnt mind it at all, the 2 of us being nude with strangers around, but with her friend, it could be a little awkward.
