A bathing resort on Trill, enjoyed as a holosuite programme by Jadzia Dax and a reluctant Kira Nerys in 2372.
The Hoobishan Baths are a spa on the Trill homeworld, mentioned in the Deep Space Nine episode The Way of the Warrior.
Jadzia Dax persuades Kira to join her in a holosuite recreation of the baths at Quark's. The two emerge in robes, with Dax relaxed and Kira plainly not. She complains that she could not enjoy being fussed over by people who were not real, and Dax teases her for lacking imagination.
The scene is a light moment before the Klingon fleet arrives at the station, and it helps to set up the friendship between the two women that runs through the rest of the series.
