We Only Use Cedar For Outdoor Saunas

Why choose our sustainably sourced cedar over other timbers? Cedar carries many natural benefits to make it the clear choice for our saunas.

Heats up faster and holds heat longer — saves energy, extends sessions.

Cedar resists moisture, decay, and pests for durable, long-lasting outdoor saunas.

Cedar’s natural aroma, air purification, and antimicrobial benefits outperform other timbers.


The extras that Make A Difference

Enjoy complete peace of mind with toxin-free materials, intuitive control from the EasyPress™ control panel, and the calming glow of ZenGlow™ chromotherapy—thoughtfully designed for your health, comfort, and total relaxation.

  • Immerse yourself with Sustainable, Toxin Free Materials

    Made from FSC® Certified Rustic Cedar, this sauna is designed to stand up to the elements. Cedar is naturally rot-resistant, pest-resistant, and an excellent insulator, so it heats faster and stays warm longer.

  • Stain Your Way

    Every house, bach, and deck is unique – that’s why we deliver our premium cedar unstained. This gives you the freedom to choose the perfect stain to complement the space where it will be placed.

Certified & Safe For Your Home

Alpine Spas is one of few Sauna retailers operating with official New Zealand electrical certification. This means our products have been audited to the highest standard of electrical compliance and safety to ensure a product that is safe, efficient, and designed to last.

Relax More, Spend Less With Energy-Efficient Heating.

The Infrared Barrel Sauna is designed with energy efficient in mind- using advanced insulation and smart heat control to deliver powerful performance without driving up your power bill.

30% More Heat Retention & Lower Running Costs

Our Sauna holds 30% more heat than full glass panel Saunas on the market- so you can have a more efficient Sauna with faster heat up times that costs you less to run. The Sauna costs less than $1 an hour to run. It’s a low-cost way to tap into daily wellness at home. Based on NZ's average power costs.

Thickest Safety Glass On The Market

The tempered safety glass isn’t just strong, it’s built to insulate. Thicker than standard panels, it helps keep the warmth in and the cold out for better performance and energy savings.

Wellness Starts with Warmth

Regular sauna sessions do more than help you relax. A recent study from Luleå University of Technology in Sweden found that people who regularly use saunas report better overall health, more energy, and lower blood pressure. They also experience less physical pain, improved sleep, and a stronger sense of well-being.
