The Threshold Sauna is built around a single idea: every form of stress has a point of transition.
Heat is not the destination—it is the threshold. The moment where the body shifts from resistance into release, from tension into adaptation.
Designed for two people, The Threshold Sauna turns infrared therapy into a controlled passage between states. Not escape. Not comfort. Transition.
Crafted from solid Hemlock wood, the structure is minimal and deliberate. Clean geometry. No excess. A contained environment where heat becomes architecture and stillness becomes the outcome.
Powered by 1750W far-infrared heating, the system delivers deep, even thermal penetration designed to support recovery, circulation, and muscular reset. The experience is steady, immersive, and uninterrupted.
A modern touchscreen control panel allows precise control over time and temperature. No complexity. Only adjustment of state.
The Threshold Sauna is designed for homes, hotels, and performance environments where recovery is treated as a discipline, not a luxury.
Warranty
The Threshold Sauna is covered by a one-year limited warranty against manufacturing defects in materials and workmanship under normal use.
This does not include damage caused by improper installation, misuse, unauthorized modification, external environmental factors, or commercial use outside intended specifications.
Warranty claims are assessed based on order details and supporting documentation. Resolution may include repair, replacement parts, or full unit replacement depending on evaluation.
Shipping and delivery
- Free standard shipping to the contiguous United States. Remote locations, islands, inside delivery, white-glove and expedited service are quoted separately.
- Orders are processed in 2–4 business days. Delivery usually follows 5–15 business days after shipment. These are estimates, not guaranteed dates.
- Inspect your delivery before you sign. Note any damage on the delivery receipt, photograph it, and contact us within 48 hours. Anything that arrives defective must be reported within 7 days.
Returns: 30 days from delivery, with a return authorization from us first. A 20% restocking fee applies, you cover return shipping, and because shipping was free on the way out the actual outbound freight is also deducted from the refund. Cancelling after processing has started incurs a 5% fee; once the order has shipped a cancellation is handled as a return. Custom, assembled, installed and clearance items cannot be returned.
Warranty: 1 year limited, residential use, original purchaser. Covers manufacturing defects in materials and workmanship. The remedy is repair, replacement parts or unit replacement — not a cash refund.
