Overview

The Solstice range is HELIX's premium traditional sauna collection, built in quality timber with intuitive controls and a clean, elegant form. It delivers the full Finnish sauna experience — deep, dry heat at 80 to 100°C — for cardiovascular conditioning, recovery and deep relaxation. Designed for indoor or outdoor placement, it is the considered entry point into serious heat therapy.

The outcomes

What it delivers

There's a reason the sauna has outlasted every wellness fad of the last decade: the evidence keeps getting stronger. Solstice delivers the full Finnish experience — deep, dry heat that leaves people loose-limbed, calm and genuinely restored — and behind that feeling sits some of the most striking longevity data in modern medicine, drawn from decades of Finnish research. For a facility, heat is the rare amenity clients use four times a week and never tire of: high utilisation, low running complexity, and a ritual that quietly becomes the reason they keep their membership.

Questions, answered

Good to know

What does the research on sauna use actually show?+
A long-running Finnish cohort study followed thousands of people for two decades and found that frequent sauna use was associated with markedly lower cardiovascular and all-cause mortality, and lower dementia risk, compared with occasional use. These are population-level associations for the modality, not a promise about any individual — but the evidence base is unusually strong for a wellness amenity.
Can it go indoors or outdoors?+
Both. Solstice is built in quality timber for indoor or outdoor placement, so it can sit inside a wellness suite or as a garden-room centrepiece.
How often should clients use it?+
The strongest associations in the research came from four to seven sessions a week. In practice that high frequency is exactly what makes a sauna such a well-used, sticky amenity for a facility.
What heater and timber options are there?+
The Solstice range offers a choice of size and configuration with intuitive controls. Our team helps you specify the right heater and layout for your space and expected throughput.
Is it hard to run day to day?+
No — a traditional sauna is mechanically simple and inexpensive to operate, which is part of why utilisation-to-cost is so favourable.
Is sauna use suitable for everyone?+
Most healthy adults tolerate it well, but pregnancy, certain cardiovascular conditions and alcohol are common cautions. We provide guidance you can display and brief staff on.
