Description

HealthHQ Radiant Plus+ Outdoor Full Spectrum Sauna

Our largest outdoor infrared sauna, with room for six. Made for hosting, sauna groups and bigger households.

The Radiant Plus+ is the biggest sauna in the Radiant range. It seats up to six people on a 1.8 m × 1.5 m footprint and is the deepest model in the line-up, so nobody is squeezed in. Full spectrum infrared (near, mid and far) means everyone gets a comfortable, even session together. It suits larger families, friends who sauna together every week, and anyone who wants their backyard to be the place people gather.

Gentle Heat, Deep Sweat

In a traditional sauna, it's the hot air that makes you sweat. Full spectrum infrared warms your body directly instead, so you get a deep sweat at a much more comfortable air temperature. That makes the Radiant Plus+ easy to enjoy for first-timers and regulars alike, and it means a group can settle in for a longer session without anyone tapping out early.

  • Near infrared: The lightest of the three, felt as a gentle warmth on the skin. It's the wavelength behind red-light therapy and is associated with skin health and repair
  • Mid infrared: Penetrates further into soft tissue to help loosen tight muscles, ease stiffness and support circulation and recovery
  • Far infrared: The deep, enveloping heat that slowly raises your core temperature and brings on a full, cleansing sweat

Why You'll Love the Radiant Plus+

  • Room for Six: 1700L*1400D*1850H mm inside, with the extra depth and headroom that make a full group session feel relaxed rather than cramped
  • Weatherproof Aluminium Shell: Powder-coated aluminium outside and an aluminium roof shrug off New Zealand weather with next to no maintenance, while XPS insulation keeps the heat where it belongs
  • Natural Timber Inside: Canadian Hemlock as standard, or upgrade to knotless red cedar for the warm, woody scent that sets the tone the moment you step in
  • Low EMF Heaters as Standard: Glass heaters under 10 mG, carbon heaters under 3 mG, and under 2 mG on the seat
  • 8mm Tempered Glass: Tough, safe and bright. Natural, black tinted or mirrored, depending on whether you want the view or the privacy
  • Chromotherapy Lighting: Seven colours to set the mood, from a calm evening wind-down to a lively session with friends
  • Built-In Sound: Bluetooth, USB and FM, so the music, podcast or meditation is shared by everyone in the room

Not Sure You Need Six Seats?

The Radiant (4 person) and Radiant Mini (2 person) share the same design in smaller sizes, and both run off a plug rather than being hard-wired. If you'd like help weighing up space, power and how you'll use it, get in touch. We're always happy to talk it through, no rush and no pressure.
