rheinwelle - die rheinhessische Wasserwelt

The rheinwelle stands among the orchards of Rheinhessen between Bingen, Ingelheim and Gau-Algesheim, and is run by Regionalbad Bingen-Ingelheim GmbH at Binger Straße 99, 55435 Gau-Algesheim. The building's plan was modelled on the course of the Rhine. The bath dates from 2005, when it replaced the town's indoor and outdoor pool at the Blumengarten. The house is divided into a Funwelt, a Sportwelt, a Saunawelt and a gastronomy area with a sauna bar and a pool restaurant that can also be entered without a bathing ticket.

The only special water is brine. The operator runs a year-round outdoor brine pool and writes that its Natursole is of medical quality, that studies show its minerals and trace elements act on skin and organism, and that the water temperature is 30 °C; it publishes no concentration in grams per litre, no spring, no borehole and no analysis. While the brine tank is moved into the new extension, the outdoor pool runs on fresh water instead of brine, expected until spring 2027. The rest of the water is ordinary heated pool water.

In the Funwelt the Erlebnisbecken is 29 °C and holds a current channel, waves set off at regular intervals by the movement of a large red lighthouse, bubble loungers, water spouts, a climbing rock and a climbing dolphin from which climbers fall into the water. The whirlpool is 31 °C and the parent-and-child pool is likewise 31 °C, with water toys, a mini slide and a mushroom shower. Two large slides were rebuilt with new routes: a Magic Tube with light, sound and animated effects, and a Turbo Slide with LED effects and timing. In the Sportwelt the operator describes a sports pool of six 25-metre lanes, 1.80 to 3.80 m deep at 27 °C, with one-metre and three-metre boards, and a separate teaching pool 0.75 to 1.25 m deep at 30 °C. An extension with a competition pool of six 25-metre lanes and a 125 m² teaching pool is under construction and due for completion in 2027.

The Saunawelt has "Sieben unterschiedliche Saunen und ein Dampfbad": indoors a low-temperature sauna at 60 °C, a steam bath at 40–50 °C and a Finnish sauna at 90 °C, outdoors a meditation sauna at 70 °C, an Aufguss sauna at 100 °C, a panorama sauna at 80 °C, a wine-cellar sauna at 80 °C with a masonry barrel vault and original wine casks, and a Kelo sauna house at 90 °C. Cooling is by an ice fountain, a plunge pool and a naturally laid-out bathing pond, put at 800,000 litres, set in 2,200 m² of lawn. Rest areas include a lounge with a view over the sauna garden, a fireplace room, a rest gallery and a rest house with four double water beds.

The bath is open Monday to Sunday and on public holidays from 10:00 to 23:00, with bathing and sauna time ending at 22:30; it closes on Christmas Day, and opens from 10:00 to 15:00 on Christmas Eve and New Year's Eve. All areas including saunas and pools are described as step-free, with lifts at the pools.
