On a Friday afternoon I shared a lane with only one other swimmer. It was not crowded at all. A swim cap and an appropriate swimsuit (no shorts!) are required. To get a key for the lockers, you deposit a picture ID. With the entrance fee you also receive a coin that can be used either for a warm shower (lasts only for about 60 seconds, so wash off the soap quickly!) or for the hair dryers downstairs beside the dressing rooms. There is a hairdryer upstairs beside the showers, however, which can be used free of charge. As I recall, both the hair dryers and showers can also be activated by €0.20. One more important thing: When using the shower, you must keep on your bathing suit! A single, but only cold shower exists, if you want to get wet before entering the pool and save the money...
