Check before you go
We have not verified price or day-pass cost, whether day passes are sold, opening hours, whether there is a cold plunge, mixed or gender-separated sessions, whether you must book ahead. The venue’s website or a phone call will have the current answer.
Heat and cold exposure is not right for everyone. If you are pregnant or have a heart condition or other health concern, ask a doctor first. See our sauna time guide and etiquette guide.
