The Stadionbad was built in 1972 as one of the most modern swimming pools in Germany. The building is shaped like a seashell. The pool features a 50 × 21-meter swimming pool with a 1-meter diving board, a 3-meter tower, and a large diving tower with an elevator and diving platforms at heights of 5 meters, 7.5 meters, and 10 meters. At the diving tower, there are 22 large underwater windows in the pool at a depth of approximately two meters, allowing visitors to observe the diving area from the basement level. The pool also features a 26 × 12.75-meter non-swimmer pool with a small slide, massage jets, and a water mushroom, as well as a small wading pool with a water-spouting clown for babies. Other amenities at the Stadionbad include a bistro with glass windows overlooking the swimming hall, a swim shop, a sauna, lounge chairs, and heated benches. The outdoor area features a sunbathing lawn of approximately 5,000 m² with a play area for children and table tennis tables. The Stadionbad also hosts numerous water sports events and competitions, some of which are international. For spectators, there are two grandstands with a total of 400 seats.
