House of Hudson Day Spa

1311 4th Ave N, Nashville, TN

House of Hudson Day Spa occupies a restored 1800s brick house on 4th Avenue North in Germantown, the Nashville branch of a small California spa group with sister locations in Laguna Beach and Palm Desert. It is a proper day spa first, with massage, facials and body treatments in the old rooms upstairs and down, but its Recovery Room is the reason it lands on a sauna map: a private room with an infrared sauna against the exposed brick and a cold plunge beside it, which you can book on its own without a treatment attached. The Recovery Bundle is the move, pairing an infrared sauna session with the plunge for roughly $55 (about $15 more than sauna alone) over an hour, and the room takes up to four people, so couples and small groups book it together. Hours are Wednesday to Sunday, 10 a.m. to 6 p.m., with reservations required and weekends filling first; cancellations need 24 hours' notice. A Germantown Founding Membership takes 20% off the regular menu with monthly service discounts and a complimentary drink. Guests 16 and up are welcome, parking is on the street, and the staff are used to walking first-timers through their first plunge. Reviewers describe it as an urban oasis: serene, beautifully kept, scented, with a front desk that remembers you. It is the gentlest entry point to contrast therapy in the neighborhood, a spa afternoon with a plunge in it rather than a recovery studio.
