Golden Designs • GDI-8040-03
8000 Reserve 4-Person Full Spectrum Infrared Sauna with Himalayan Salt Bar
The GDI-8040-03 is the 4-person cabin in the Golden Designs 8000 Reserve range: 70 inches wide, nine full spectrum heating elements in a 6 + 3 configuration, an integrated Himalayan salt bar and floor heater, and 2,700 watts requiring two separate dedicated 120V / 15A non-GFCI circuits. It is the widest bench layout below the 6-person model and the point in the range where installation planning shifts from one circuit to two.
Wellari Expert Take
Why Consider the Reserve GDI-8040-03?
This is the family cabin of the Reserve range. At 70″ wide with a 41″ body depth it seats four along a wide bench rather than pushing depth into the room, which makes it easier to place along a long wall than the deeper 3-person GDI-8230-01. Nine heating elements across that width is the same count the 6-person cabin carries, so heat coverage per occupant is generous. The requirement to plan for is electrical: 2,700 watts means two separate dedicated 15-amp circuits, and that is a decision to make before ordering, not after delivery.
Best For
- Households where three or four people will use the sauna, together or in rotation.
- Rooms with wall width available but limited depth — the body is only 41″ deep.
- Installations where two separate 15-amp circuits can be dedicated to the sauna.
- Buyers who want the full Reserve specification — salt bar, floor heater, touch-screen controls, oversize chromotherapy — at four-person scale.
- Finished basements, home gyms and dedicated wellness rooms with freight access.
Reserve GDI-8040-03 Features & Buying Details
PureTech™ Full Spectrum Heating
- Heater configuration: Documented by Golden Designs as 6 + 3 — 9 heating elements in total
- Heating technology: PureTech™ full spectrum
- Wavelengths: Golden Designs states the panels use near, mid and far infrared wavelengths to deliver full spectrum heat while maintaining a near zero EMF standard
- Floor heater: Included
- Rated power: 2,700 watts
- Capacity: 4 person
What full spectrum means here: a far infrared-only cabin emits a single band. A full spectrum cabin adds near and mid infrared — near infrared is absorbed closer to the skin surface and warms the cabin faster, far infrared penetrates further and provides sustained background heat. Golden Designs publishes the 6 + 3 configuration but does not publish which count corresponds to which band, so Wellari does not state a near/far split for this model.
Near Zero EMF — What Golden Designs Documents
Golden Designs classifies the 8000 Reserve full spectrum range as Near Zero EMF.
Why we do not publish a number. Golden Designs' current V26.0 documentation, all issued on the same date, states different Near Zero EMF measurement figures for its full spectrum range in different documents — the model-family sheet, the full spectrum sheet and the dealer workbook do not agree with one another. Because those figures conflict, Wellari publishes the manufacturer's classification and does not quote a milligauss value for this model until Golden Designs reconciles them.
If a specific measured EMF figure is a decision criterion for you, contact us and we will request it from Golden Designs in writing.
When comparing sauna models generally, always compare the stated figure together with the distance at which it was measured. A lower number taken further from the panel is not necessarily a lower-emission cabin.
Electrical & Installation Planning — Two Circuits Required
- Rated power: 2,700 watts
- Electrical service: Two separate 120V / 15A non-GFCI outlets
- Configuration: Two dedicated circuits — a single 20-amp circuit is not sufficient for this model
- Installation environment: Indoor use only
- Designated use: Residential
Two circuits means two independent runs from the panel. At 2,700 watts the cabin exceeds what one household circuit can carry, so Golden Designs specifies two separate 15-amp circuits, each with its own breaker and outlet, and specifies non-GFCI outlets. Two receptacles wired to the same breaker will not satisfy this.
Have a qualified electrician confirm that two separate dedicated circuits can be run to the installation point before you order. This is the most common cause of delay between delivery and first use, and running a second circuit is far more disruptive once a 4-person cabin is assembled against the wall.
Himalayan Salt Bar & Cabin Materials
- Himalayan salt: Integrated Himalayan salt bar
- Wood: 100% reforested Canadian Hemlock Fir
- Colour: Natural
- Glass: Bronze-tinted tempered glass door
- Assembly: Clasp-together panel construction; Golden Designs states the cabin is assembled by two adults
- Country of manufacture: China
The salt bar is a Reserve-series feature fitted across the range. Capacity, footprint, heater count and electrical service are what actually differ between Reserve models.
Lighting, Audio & Controls
- Control panel: Touch-screen control panel
- Radio: FM station, integrated into the touch-screen panel
- Audio: Bluetooth connectivity
- Auxiliary audio: MP3 auxiliary connection
- Chromotherapy: Oversize colour therapy lighting with red light
- Exterior lighting: Exterior accent lighting
The oversize colour therapy system is fitted to the larger Reserve cabins — GDI-8030-03 and above. The two smallest models use the standard-size system.
Size & Space Planning
- Exterior dimensions: 70″ W × 41″ D × 75″ H
- Roof overhang: Adds approximately 5″ to the depth
- Capacity: 4 person
- Assembled weight: Approximately 475 lb
Wide but shallow. At 70″ wide and 41″ deep this cabin needs a long wall rather than a deep alcove — it is nearly a foot wider than the 3-person GDI-8230-01 but 9″ shallower. Allow approximately 5″ beyond the 41″ body depth for the roof overhang.
Measure the full delivery path as well as the installation area: doorways, hallways, stair turns and tight corners. At approximately 475 lb assembled the cabin is not practical to reposition once built, so decide the final location before assembly begins.
Shipping, Freight & Assembly
- Freight method: LTL freight
- Delivery: Curbside only, on a pallet, by a freight carrier
- Cartons: 3 cartons on 1 pallet
- Shipping weight: Approximately 560 lb
- Assembly: Clasp-together panel construction, assembled by two adults
Plan for curbside delivery. The carrier brings the pallet to the curb and does not move it into the home. With 3 cartons totalling approximately 560 lb, arrange at least two people and ideally an appliance dolly to move them from the curb, and confirm a freight vehicle can reach your address before ordering.

Common Questions
Can I run the GDI-8040-03 on a single circuit?
No. Golden Designs specifies two separate 120V / 15A non-GFCI outlets for this 2,700-watt model, each fed independently from the panel. Two receptacles on one breaker will not meet the requirement. Confirm with a qualified electrician before ordering.
How much wall space does it need?
The cabin is 70″ wide and 41″ deep, with the roof overhang adding approximately 5″ to the depth. It suits a long wall rather than a deep alcove. Allow additional working space around the cabin during assembly.
Why doesn't this page state an EMF number in milligauss?
Because Golden Designs' own current documents disagree. Three V26.0 documents issued on the same date give three different measurement figures for the full spectrum range. We publish the manufacturer's Near Zero EMF classification and are seeking a reconciled figure. Ask us if you need it in writing before ordering.
How does it compare with the 6-person GDI-8260-01?
Both carry nine heating elements and both need two dedicated 15-amp circuits. The 6-person cabin is 73″ wide and 55″ deep against 70″ wide and 41″ deep here, draws 2,900 watts against 2,700, and ships in 5 cartons rather than 3. If depth is available and you need six seats, the 8260-01 is the step up; otherwise the 8040-03 fits far more rooms.
How is it delivered, and what do I need to arrange?
By LTL freight, curbside only, on a pallet, in 3 cartons with a shipping weight of approximately 560 lb. The carrier will not bring it inside. Arrange at least two people and ideally an appliance dolly, and confirm a freight vehicle can access your address.
What warranty applies?
Golden Designs provides a 5-year manufacturer warranty on this model. Coverage and claim procedures are set by the manufacturer and may vary by component.
