  • Air Mixing Technology – Saunum patented air blending system mixes cold oxygen-rich air from the floor with hot oxygen-poor air off the ceiling to solve the discomfort so many associate with sauna. Whether you like it extremely hot, or just warm, Saunum delivers both in a way that heat and oxygen are felt head to toe.
  • European Design – With an elegant black steel finish, Saunum combines Scandinavian design and quality materials.
  • Massive Stone Capacity – Stones are the heart of a Nordic sauna. Ample stones result in softer, more even heat, and can produce more luxurious steam. Large 154-pound stone capacity (required 5 boxes sold separately)

Please note that each natural stone is unique in shape and size. We recommend purchasing an additional box of sauna stones to allow you to choose the highest quality of stone for fit, form, and function (Additional freight charges will apply).

  • Himalayan Salt Reservoir – Saunum’s Himalayan salt tray is positioned within the air stream so that salt ions are propelled throughout the sauna to deliver health benefits more effectively.
  • Wi-Fi Control Option – The available AirIQ Wi-Fi control unit allows you to activate a tailored sauna profile and have your custom sauna ready at the time that you specify on your mobile device.
  • Dry your Sauna – Go ahead, toss water onto the rocks! Saunum is engineered for water-tossing, and when you're done enjoying the steam, the patented fan system will conveniently help dry your sauna.
  • UL Certification – Safety and reliability are priorities at Saunum, and each product is engineered to exceed strict UL standards.
  • Available Aromatherapy - Add another sensory layer with Saunum's optional aromatherapy system, which infuses aroma into the steam to further transform your experience.
  • For sauna rooms from 106 to 177 cu. ft.

Shipping & Handling Policy for all Brands

An "Order Confirmation" email confirming our receipt of your order will be sent to you as soon as you place it.

We check with our suppliers to see if your order is in stock and ready to ship right away. The majority of pre-made saunas and accessories are available for shipping right away, however custom saunas take longer.

Your order will ship as soon as your order is accepted and your money has been received (unless it is a special case sauna as mentioned above). On the day your order ships, we will email the tracking information to the email address you provided during checkout.

All saunas are delivered in a 53-foot semi-truck with a single driver, who will unload the pallet to your curbside or driveway only.

Due to the unique nature of many of our saunas, many may require at least 3–4 weeks before they are ready to ship; if the sauna is especially specialized or personalized, this time frame may be extended.

Sauna accessories and readymade saunas (like infrared) are the exceptions, and if they are in stock, they should be delivered 7-10 business days after payment is received.

Shipping of just accessories will have a $55.00 flat shipping fee
