Why We Selected the Spectra
We selected the Spectra Sauna Cabin for its ability to balance modern aesthetics with all-weather reliability. From its thermally modified wood exterior to its Firestone EPDM roof and Harvia-powered heat system, Spectra reflects our standards for longevity, performance, and architectural integrity.
This model is ideal for clients seeking a refined outdoor sauna that performs as beautifully as it looks.
The Experience
The Spectra experience begins with privacy and light. A dark grey Parsol glass front filters sunlight while preserving warmth and visual depth, creating a space that feels secluded yet open. Inside, warm Tyrol wood walls contrast with smooth thermo-aspen benches, grounding the space in natural texture.
Consistent heat, gentle steam, and subtle RGB lighting create an environment suited for unhurried sessions — whether at sunrise, after training, or as part of an evening wind-down ritual.
Designed to Support Recovery & Longevity
Traditional sauna bathing supports recovery by encouraging circulation, muscular relaxation, and stress reduction through sustained heat exposure. The Spectra’s Harvia Virta heater delivers steady, evenly distributed warmth, making it suitable for regular, year-round use.
When integrated into a balanced wellness routine, outdoor sauna sessions may complement long-term vitality by supporting recovery, relaxation, and overall resilience.

Weight
The Spectra Sauna Cabin is delivered fully assembled via flatbed trailer. Customers are notified approximately two weeks prior to delivery to allow for proper site preparation.
Due to the size and weight of the unit, a forklift or crane is required for placement, and manual offloading is not recommended. Installation of the sauna heater must be completed by a licensed electrician. The delivery path must be clear and accessible for equipment.
Saunas should be installed on a firm, level surface with proper drainage, such as concrete, decking, pavers, or compacted gravel.
The ThermaSol Spectra Sauna Cabin includes a 1-year manufacturer’s warranty. Core Human Health provides personalized pre- and post-purchase support to assist with site planning, delivery coordination, installation readiness, and long-term care considerations.
Our role is to ensure your outdoor sauna integrates seamlessly into your environment and lifestyle.
“Invest in a recovery ritual you’ll return to.”
