Wiehler Wasser Welt

Wiehler Wasser Welt is the family bath of Wiehl in the Oberbergischer Kreis, run by Freizeit- und Sportstätten Wiehl at Mühlenstraße 23. The operator describes five pools. The children's pool is held at 32 °C and contains a water snake, two tigers, a hut with a slide, caves, a tipping bucket and a rock with a hand pump and an operating wheel. The course pool has a movable floor and is held at 30 °C, with the depth adjustable from 0 to 1.80 m for different courses. The sports pool covers 318 m², is 2.00 m deep and is held at 28 °C, with five 25-metre lanes and starting blocks; its folding walls to the outdoor grounds turn the hall into an open-air bath in the summer season. The brine pool covers 155 m², is 1.20 m deep and is the warmest at 34 °C, equipped with two neck showers, eight whirl loungers, one floor bubbler and three back-massage stations. The outdoor diving pool is 3.80 m deep at 24 °C, with 1 m, 3 m and 5 m platforms and 1 m and 3 m springboards.

The water is heated fresh water except in the brine pool (Solebecken), which is the bath's one saline basin. The operator publishes no thermal spring, no well, no source temperature and no brine concentration or mineral analysis, and it is not a thermal bath; the brine is a treated pool, not a named spring.

The operator gives the combined area of all pools as 718 m², which it compares to about 3.5 tennis courts.

The single slide is the Speed-Rutsche, 68 metres long, whose landing area is underground; riders pass four stroboscope lights, a running-light section and a light-roller section. The outdoor area, opened in full for the summer season, has a large lawn, a beach bar, three wade-through basins, a sand play area with play equipment and a relax beach section with loungers. The operator describes no sauna.

Opening hours are Tuesday, Wednesday and Thursday 13:00–20:00, with early swimming on Tuesday and Thursday 06:30–08:00, Friday 12:00–21:30, and Saturday, Sunday and public holidays 10:00–19:00; the operator lists no Monday hours. The bath is closed on Christmas Eve, both Christmas days, New Year's Eve and New Year's Day, and different hours apply in the summer holidays.
