This isn’t a barrel kit.
Hand-built clear Western Red Cedar, inside and out. Traditional löyly heat over hot stones, integrated red and near-infrared light therapy, and a hot room built the way sauna has been done for centuries — the way it should be.
Cedar Sauna, in detail.
Real löyly, real cedar
Ladle water over hot stones and the room answers. Clear Western Red Cedar holds the heat and the scent the way no barrel kit or flat-pack can. Every board is selected and fit by hand.
Light therapy, built in
An integrated PlatinumLED SaunaMAX Pro panel adds red and near-infrared light to the heat — no add-on, no afterthought. Sensor and app connectivity available.
Built to stand outside
Standing-seam metal roof, dual-pane low-E glazing, R-19 walls, epoxy floor. This is an outdoor building, finished to live in your yard for decades.
Why thermal therapy
What heat can support.
Decades of peer-reviewed research connect heat, cold, and light exposure with measurable changes in the human body. We keep the claims careful because bodies are different, and outcomes are not guaranteed.
Recovery
Heat exposure raises muscle temperature and activates stress-response pathways your body uses for repair.
Sleep
The post-sauna temperature drop can help the body downshift toward deeper rest.
Mental clarity
Cold exposure can raise norepinephrine, which is part of why contrast often feels sharp and alerting.
Cardiovascular
Regular Finnish sauna bathing is associated with vascular and cardiovascular benefits in long-term studies.
Metabolism
Heat and cold both create a controlled physical stress that asks the body to regulate itself.
Immunity
Thermal stress is being studied for its relationship to immune signaling and adaptation.
Inflammation
Heat, cold, and recovery protocols are being studied for changes in inflammatory markers.
Longevity
The strongest sauna data is observational, but the signal around frequent use is hard to ignore.
Integrated light therapy
PlatinumLED SaunaMAX Pro
A sauna-rated red and near-infrared panel mounted inside the hot room. It layers photobiomodulation into a sauna session you were already going to take.
- 320 LEDs with 201W power consumption
- 480 / 630 / 660 / 810 / 830 / 850 nm spectral output
- Fan-less, all-aluminum, IP65, sauna-rated to 150°F / 65°C
- Remote, timer, and separate red / NIR intensity control
- 39" × 10" × 3.5", 17 lb panel

Research-informed
What the science says - and doesn’t.
The research on heat, cold, and light is encouraging, but not definitive. Different people respond differently. We build the sauna to make the ritual visible and repeatable, not to promise specific outcomes.
Heat
- Cardiovascular load similar to light-to-moderate exercise
- Heat-shock protein response studied in thermal stress
- Post-sauna temperature drop may support sleep
Cold
- Norepinephrine rise can feel alerting
- Brown adipose activation is part of cold-exposure research
- Autonomic adaptation and cold tolerance may build over time
Contrast
- Layers heat and cold stressors in a single session
- Practices rapid shifts between warmth and cold
- Often reported as more mood-elevating than either alone
Light
- Red and near-infrared wavelengths interact with mitochondrial pathways
- Studied for recovery and discomfort in some protocols
- Built into the sauna, no extra device or habit
Yutori saunas and light panels are general wellness products. We always recommend discussing substantial routine changes with your healthcare provider.
Pair it with.
Heat, then cold, then rinse. The builds are made for each other.
