Bathhouse lists Flatiron, Williamsburg, and Atlantic Avenue locations, with day passes and treatment booking paths. Do not assume photographs, pools, or schedules from one location describe another. A future-location announcement is not proof that it is bookable.
Decide whether you want shared bathing time, a massage, or a scrub. Check the chosen booking's amenity access, arrival time, and any time limit. For two people, confirm both reservations at the same branch before paying; a shared visit is different from a couples treatment.
Ask about supplied items, changing arrangements, optional charges, and cancellation rules. Leave time around the treatment rather than filling every minute with heat experiences. This is a guide to the operator's published offering, not a firsthand inspection or a claim of health benefits.
