Notes from the manufacturer page: Bath shape, two-person Specifications verified 2026-09-08.

Cold water immersion places real stress on the heart and circulation. Anyone with a cardiovascular condition, high blood pressure, a history of arrhythmia, or who is pregnant should speak to a doctor before using a cold plunge. Never plunge alone. Start with short sessions at mild temperatures and progress gradually. Read the full safety guide.
