Laguna Badeland

Laguna is run by Laguna GmbH at Am Wasserwerk 2, 79576 Weil am Rhein, in the border region of Switzerland, France and Germany; the operator puts more than 750,000 inhabitants in the immediate catchment and about 450,000 visitors a year. The complex has three parts: the indoor Erlebnis-Badeland with a wave pool and children's paradise, a large open-air bath, and the Sauna Parc, described as 3,000 m² with seven themed saunas, an indoor pool, an outdoor pool, a plunge pool, an ice fountain, a Celtic steam bath, a whirlpool and a 4,000 m² garden.

The operator lists five pools in the bathing hall with their temperatures: the wave pool at 30 °C, a 25-metre sports pool at 28 °C, an adventure pool at 34 °C, a children's paddling pool at 33 °C and an outdoor pool at 32 °C. The wave pool is described as over 40 m long under a large glass pyramid. The adventure pool covers over 170 m², with a water veil to dive through and a 60 m² broad wave slide. The children's paddling pool has a cascade, spouting animals and a mini slide. Beyond those there are Champagner-Sprudelliegen with floor jets, massage nozzles and a waterfall, and separate whirlpools described as 34 °C.

Three large slides are listed: the Black Hole, a darkened tube of over 100 metres with light effects; a Wildwasserbahn; and a new funnel slide that drops riders from around ten metres into a vortex. No lengths are given for the latter two.

The water in the Badeland is plain heated water — the operator makes no thermal or mineral claim for it anywhere. Brine appears only in the sauna park, and only seasonally: the operator fills the outdoor pool there with Swiss saline brine (Schweizer Salinen-Sole) at about 30 °C from autumn to spring. No brine concentration is published.

The operator gives per-cabin temperatures: Damen-Sauna 85 °C at about 10 % humidity, Meditations-Sauna 90–100 °C, Alpenkräuter-Sauna 65 °C at about 30 %, Parc-Sauna 85 °C, Gipfel-Sauna 80–85 °C, Salzstein-Sauna 75 °C and Event-Sauna 90–100 °C with room for up to 100 people, plus the Keltenbad at 42–45 °C and about 100 % humidity. The Keltenbad is the Kelten-Dampfbad, a steam bath rather than a sauna, so it comes on top of the seven themed saunas.

The Badeland opens Monday to Sunday and on German public holidays from 10:00 to 20:00, and the operator states it runs 364 days a year, closing only on 25 December. The open-air bath is seasonal.
