The Golden Designs GDI-8040-03 is a 4-person full spectrum FAR infrared sauna in Canadian Hemlock, part of the 2025 Full Spectrum 8000 Reserve Series. It combines near zero EMF full spectrum heat with two built-in Himalayan salt bars, in a 70-inch-wide cabin that seats four.
Full Spectrum Heat, Near Zero EMF
The sauna uses nine heaters: three PureTech™ near zero EMF FAR infrared carbon panels (under 2 milligauss measured 2–3 inches from the heating panels) and six near infrared heating elements. PureTech™ technology provides near, mid, and far wavelengths (full spectrum) while maintaining the near zero EMF rating. The operating range is 118–132°F, with a maximum of 140°F.
Two Himalayan Salt Bars
One salt bar is positioned above the rear-wall heating elements and a second below the bench. The panels warm the salt during use. No other 4-person cabin we carry includes salt bars as standard.
Controls, Glass, and Dimensions
The GDI-8040-03 uses a touch screen control panel with built-in FM station, Bluetooth, and MP3 aux connection, played through the onboard sound system. The cabin measures 75″H × 70″W × 41″+5″L, with bronze tinted tempered glass, an oversize interior chromotherapy lighting system with red light feature, exterior accent lighting, and a black-finish door handle with interior towel bar.
Electrical Requirements
The sauna draws dual 120V/15A non-GFCI circuits (dedicated outlets recommended; consult a certified electrician). This avoids a 240V run in most homes — two dedicated outlets near the sauna are sufficient. It ships in three boxes at 560 lbs, delivered curbside on a pallet, and assembles with two people.

Frequently Asked Questions
Do the salt bars require maintenance?
Little. They stay dry in an infrared cabin and require occasional dusting. They are solid Himalayan salt and do not need refilling.
Why two 120V circuits rather than one 240V?
Golden Designs splits the heater load across two standard household circuits, so most buyers avoid a panel upgrade. Two dedicated outlets near the sauna are the full electrical requirement.
Is four-person capacity realistic?
The 70-inch bench seats four adults.
Is the warranty included?
Yes. Norse Steam is an authorized Golden Designs dealer; the full manufacturer warranty applies.

Low EMF Infrared Saunas: Deep Detoxification and Safe Heating
Far-infrared (FIR) is the longest infrared wavelength on the light spectrum, with a range of 3000 nm to 0.1 mm. This wavelength penetrates deeply beneath the skin, warming the body from the inside out. As a powerful detoxifying agent, FIR encourages fat-based sweating, where many toxins are stored, making it especially effective for cleansing at a cellular level.
Optimal Temperature Range
These saunas are designed to operate within an ideal temperature range of 118°F to 132°F, with the capability to reach up to 140°F for users seeking higher heat.
Low EMF Standards
Our Low EMF Infrared Saunas maintain EMF levels between 6-10 milligauss (MG), measured 6 to 8 inches from the heating panels, offering a safe environment for regular infrared therapy sessions.
Full Spectrum Infrared Saunas: Comprehensive Health Benefits
Full Spectrum Infrared Saunas combine NEAR, MID, and FAR infrared wavelengths to target multiple health benefits.
- FAR Infrared: Deeply penetrates fat tissue, activating sweat glands to release toxins.
- MID Infrared: Reaches muscles and joints, boosting circulation and reducing pain.
- NEAR Infrared: Targets the skin’s surface, promoting cell health, skin renewal, and reducing inflammation.
Near Zero EMF Infrared Saunas: Safe and Effective Heating
Golden Designs’ Near Zero EMF Saunas offer a natural, low-EMF thermal experience using PureTech Near Zero EMF Heating Technology. These saunas deliver FAR infrared heat with EMF levels kept under 2 milligauss (MG) at a close range of 2 to 3 inches from the heating panels.
- Temperature Range: Ideal between 118°F and 132°F, with a max of 140°F.
- Safety: Maintains near-zero EMF exposure, prioritizing a safe environment.
Ultra Low EMF Infrared Saunas: Safe, Deep Heating
Dynamic Ultra Low EMF Saunas deliver a natural thermal experience with minimal EMF exposure, using PureTech Ultra Low EMF Heating Technology and FAR infrared wavelengths.
- Temperature Range: Operates ideally between 118°F and 132°F, with a maximum of 140°F.
- EMF Safety: EMF levels kept under 3 milligauss (MG), measured 6 to 8 inches from heating panels.
These saunas provide effective, deep-reaching heat therapy in an ultra-low EMF environment, offering a safe option for consistent infrared use.
