Product Description

Off-Grid Wellness. Powered by the Sun.

The Thermasol Solaris redefines outdoor wellness as the first fully off-grid, solar-powered electric sauna available in the United States. Designed for ultimate flexibility and sustainability, Solaris delivers a premium sauna experience without requiring a traditional power connection.

Recognized by TIME as one of the Best Inventions of 2025, Solaris combines innovative solar technology with contemporary European design. Solar panels and an integrated battery pack power the system, while a panoramic tinted glass wall fills the space with natural light and maintains privacy.

Inside, brushed tile oak finishes, integrated LED lighting, and a Wi-Fi-enabled heater create a relaxing retreat that can be placed virtually anywhere. Delivered fully assembled, Solaris offers a seamless path to sustainable wellness.

Installation Notes

Shipping Details

    • Free shipping is included for eligible deliveries within the contiguous United States.
    • Outdoor saunas are delivered fully assembled by commercial freight.
    • Customers are typically contacted approximately two weeks before delivery to schedule a convenient delivery appointment.
    • Due to the size and weight of these fully assembled units, appropriate unloading equipment (such as a forklift or crane) may be required. Manual unloading is generally not recommended.
    • Please ensure there is clear access from the delivery location to the final installation site and that suitable unloading arrangements are in place before delivery.
    • ThermaSol freight delivery is curbside only. If you would like assistance moving your sauna from the curb to its prepared final location, Between Living can help coordinate a local white-glove delivery and placement service where available, quoted and invoiced separately.

      What is White-Glove Delivery?
      White-glove delivery can help move your fully assembled sauna beyond the curbside delivery point to its prepared location on your property, such as through a driveway, side access, garden, or patio. Access and any required placement equipment are assessed by the local provider.
