ThermaSol · Since 1958
Steam & Wellness, Reimagined Since 1958
ThermaSol has defined the art of steam and wellness for more than six decades. Its sauna collection brings that pedigree outdoors and in — clean architectural lines, floor-to-ceiling tinted and mirrored glass, and brushed thermally-modified wood interiors. Every cabin is engineered around an even, enveloping löyly, powered by smart Harvia Virta, Spirit and KIP heaters with Wi-Fi control. The result is European luxury that feels as considered as the home it sits beside.

Frequently Asked Questions
Are ThermaSol saunas indoor or outdoor?
Both. The collection includes fully-assembled outdoor cabins (Fortis, Ombra, Vue, Spectra, Vera, Solaris, Nordic Dawn, Nordic Misty) and indoor cabin kits (Aalto, Astra, Lumaria) designed for interior installation.
What heater comes with a ThermaSol sauna?
Most cabins include a smart Harvia heater — typically an 8–10.5kW Virta or Spirit with Wi-Fi, or a 3kW KIP on the solar Solaris. The exact heater is listed in each product's specifications.
Do the saunas have Wi-Fi / smart control?
Yes. The included heaters pair with a CX-series digital control and Wi-Fi so you can pre-heat and adjust your session from your phone.
Are outdoor models really delivered fully assembled?
Yes. Outdoor ThermaSol cabins ship fully assembled via flatbed. A forklift or crane is required for unloading and placement, and a licensed electrician connects the heater.
What electrical supply is required?
The included sauna heater needs a dedicated 240V circuit installed by a licensed electrician; amperage depends on the heater's kW (see each product's manual). LED lighting runs on a standard supply.
What glass options are available?
Depending on the model: transparent, dark-grey tinted, Stopsol bronze, Parsol and mirrored glazing. Several cabins also offer mirrored left/right assembly so the glass corner and heater sit on your preferred side.
How should I prepare the site?
Install on a firm, level surface with slight runoff for drainage — concrete, decking, pavers or compacted gravel — with a clear, accessible path for delivery equipment.
What about shipping and warranty?
Free freight within the contiguous U.S. with curbside delivery, typically 1–3 weeks. Coverage applies to manufacturer defects in materials and workmanship under normal residential use; Sauna Co. handles claims directly. See full policies on any product page.
