The Sauna & Plunge Pool Experience
Long before saunas became a social trend, ours was already part of Wellington’s wellness landscape. Through every refit and renewal, the cedar-wood sauna and plunge pool have remained at the heart of our retreat — a timeless ritual of heat and cold that has supported generations of Wellingtonians.
Step into our spacious Finnish sauna, heated to 80–100°C, and feel the shift as muscles soften, tension fades, and the mind finds ease. The benefits are as real today as they were decades ago: physical recovery, stress relief, and an overall sense of balance and wellbeing.
Balancing the heat, our striking Grecian-style plunge pool is chilled to 5–6°C, its cool blue waters surrounded by lush greenery. Moving from sauna to pool is the practice of contrast therapy — a powerful way to awaken circulation, boost resilience, and leave the body and mind deeply refreshed.
Between sauna and plunge, take time to pause. Settle into a quiet nook, stretch out on a couch, or share the experience in our social spaces. Whether alone or with others, it’s a moment to breathe, reset, and reconnect.

To keep the sauna spacious and relaxing, we offer two types of booking sessions. Sessions are either 60 or 90 minutes (check the timetable for details). Changing time is generally in addition to your session, so you won’t feel rushed — unless a private booking follows directly after.
Our capacity is limited to ensure comfort:
Early riser sessions – max 14 people
All other sessions – max 13 people
Book a session to share the sauna with others (up to 12–13 patrons).
How to book: online, by phone, or by arriving at The Retreat.
Important: Online bookings are for one person only. If you’d like to book for two or more, please call or email us so we can confirm your group (bookings for three or more people require prepayment, which we take by credit card over the phone).
First in, first seated: once the limit is reached, you’ll need to choose another time.
Waitlist available: if a spot opens up, we’ll contact you — please confirm within a few hours.
Sauna etiquette: everyone’s comfort is respected.
Towels: please bring two (one to sit on, one to shower with). Towels can also be hired.
