Swimwear days
Unfortunately, Thermen Maarssen does not have swimwear days.
However, if you prefer to wear swimwear to the sauna, we would be happy to welcome you at one of our other Thermen Resorts on our special swimwear days. Wearing swimwear is mandatory throughout the day on these days. In the restaurant, wearing a bathrobe is mandatory. Also good to know; Thermen Maarssen also does not organize ladies' days.
