Carolus Shop

Daily from 9:30 a.m. to 8:30 p.m. bathrobes and sauna towels can be rented against a fee. Furthermore, there is the possibility of buying different kinds of swimwear and accessories.

Children

As our pools are filled with thermal water very rich in minerals, physicians recommend that small children should not take a bath in thermal water rich in minerals, as these minerals would much quicker and more intensely penetrate their thin skin than it is the case with adults.

For children’s protection we therefore allow them as guests of the Carolus Thermen from six years only. Children/youngsters between 6 and 15 years must be accompanied by an adult.
