Reserve Edition 4-Person Full Spectrum Infrared Sauna

Four people. Nine heating elements. The Reserve Edition 4-Person is the largest format in the Golden Designs flagship line — built for households where the sauna is a shared daily ritual rather than a solo home sauna feature.

At 70 inches wide with a 64-inch interior, the 4-Person provides genuine freedom of movement during a session. Stretch. Breathe. Use it the way a dedicated sauna space is meant to be used — without the compressed feeling of a unit designed for smaller footprints.

The same PureTech™ Full Spectrum technology that defines the Reserve Edition line delivers Near, Mid, and Far infrared wavelengths simultaneously. Nine total heaters — 3 PureTech™ Near Zero EMF FAR IR Carbon Panels and 6 Near IR Elements — wrap the interior in consistent, full-spectrum heat from every angle.

The Himalayan Salt Bar beneath the bench, oversized chromotherapy lighting with accent lighting, bronze privacy tempered glass door, and exterior ambient lighting are standard. This is not an entry-level sauna with premium branding. It is a premium sauna.

One important note — the 4-Person requires a dual 120V/15AMP electrical configuration rather than the single 20AMP circuit of our 2 and 3-person models. Our product specialist will walk you through the electrical requirements and placement before your order ships.
