De Bütt

Freizeitbad De Bütt stands at Zum Schwimmbad 1, 47877 Willich on the Lower Rhine and is run by the town. It is not a single open-air bath but three linked areas — Hallenbad, Freibad and Sauna — each with its own attractions and hours. Willich got an indoor bath in 1965, and the building on Schiefbahner Straße was extended by an open-air bath in 1974. After the bath burned down in 1990, the town replaced it with a family-oriented sport and leisure bath named De Bütt, opened in June 1994. The water is plain heated pool water throughout, and no spring, source temperature or mineral content is claimed.

The indoor hall lists a 90-metre Black Hole slide with its own landing pool; a 200-square-metre leisure pool with an all-year outdoor pool attached, massage jets and air bubblers at about 30.5 °C; a 25-metre sports pool with six lanes at about 27 °C; a teaching pool at about 31.5 °C; a paddling pool with a lighthouse slide at about 31.5 °C; a small-children's pool with a squirting pelican at about 30.5 °C; two whirlpools at about 33 °C; a 3-metre tower and 1-metre board; changing rooms for families, groups and individuals; and an indoor lawn. The operator lists the pools without giving a total.

The open-air bath has an adventure pool with a current channel, water curtain, bubble loungers and massage jets; a sports pool with eight lanes; an action pool with a 15-metre wide slide; a baby pool with a little-boat channel; and, alongside the water, a 160 square metre bouncing cushion, a children's mud installation, a large play device, a tricycle and bobby-car track, a football field and a lawn with old trees. The operator states one temperature for the whole open-air area: 25 °C in all pools. The open-air season runs irrespective of weather, with hours of Monday 13–19, Tuesday and Thursday 7:30–19, Wednesday, Friday, Saturday, Sunday and holidays 10–19; the bath closes on the first Sunday in September for the annual triathlon.

The sauna area is equipped with a steam bath at 45 °C, a Niederrhein bio sauna at 60 °C, a Schloßpark sauna at 80 °C and a panorama infusion sauna at 90 °C, with scented infusions, a plunge pool and cold-water area with shower and Kneipp hose, a foot basin, quiet rooms, a conservatory and roof terrace with loungers, and catering; again no total is given. The sauna is closed on Mondays because municipal savings measures have cut staffing, and otherwise opens Tuesday and Thursday 9:30–20 and Wednesday to Sunday and holidays 10:30–20, with Tuesdays all day and Thursdays until 14:30 reserved as women's sauna. All areas close on New Year's Day, Easter Sunday, Christmas Eve and both Christmas days, and for a deep clean three to four weeks before Christmas.
