Is it common among german people to visit a therme/sauna with family members?

I F27 have been working in Germany for a few months, and I have been to a few therme on women only days, and I usually see ladies of similar age/friends together, my (F55) mom came to visit me and will be staying with me for a few months, I am planning to visit a therme next weekend with my mom to relax but I'm feeling a bit weird about it, so I would like to know is it common among german people to visit sauna with family/parents ?
