Our Story

A private space
to reset.

Sauna Sanctuary is a sibling-founded contrast therapy studio in the heart of Whanganui, created from the belief that our community deserves a private space to reset, recharge, and reconnect in a world that rarely slows down.

Built on family values and a genuine love of saunas and holistic wellness, Sauna Sanctuary offers private Infrared Sauna and Contrast Therapy experiences designed to support both physical and mental wellbeing. Every booking is your own sanctuary — free from distractions, free from crowds, and entirely at your own pace.

Why Contrast Therapy

The simple power
of heat & cold.

Move seamlessly between deep infrared heat and invigorating cold, allowing your body and mind to reset, recover and recharge.

01

Infrared Heat

Infrared heat penetrates deeper than a traditional sauna — relaxing muscles and easing tension at a more comfortable temperature.

02

Cold Plunge

An invigorating cold plunge designed to reduce inflammation, enhance mental clarity, and support recovery, leaving you feeling refreshed, focused, and fully revitalized.

03

Contrast Therapy

Experience the power of contrast therapy as heat and cold work together to improve circulation, support recovery, and increase energy levels — leaving you feeling restored and recharged.

Nothing left out.

Every session includes
  • Fresh towels
  • Electrolyte sachets
  • Herbal tea
  • Face cloths
  • Aftercare products

Please note: there is no shower on site. We ask that guests arrive clean and showered.
