4-Person Indoor Infrared Sauna with Wi-Fi Control – Refresh 4

A Wider Infrared Sauna for Shared Sessions.

The Refresh 4 Indoor Infrared Sauna combines a listed four-person layout with infrared heating and Wi-Fi-enabled controls. Its wider cabin offers a larger alternative to Refresh 3 while retaining the same listed exterior depth and height.

The supplied series sheet lists Bluetooth audio, seven-color mood lighting, and a 220/240 V electrical configuration. Confirm the actual equipment ratings and supplied package before ordering.

This is an infrared sauna, not a traditional heated-stone sauna or a dedicated steam room.

Key Features at a Glance

• Four-Person Capacity: Listed for shared seated sessions, subject to user size and the approved bench layout.
• Wider Cabin: Approximately 70 inches wide × 47 inches deep × 75 inches high externally.
• Infrared Heating: Series-listed full-spectrum heaters; exact components and spectral coverage to be confirmed.
• Wi-Fi Control: Confirm supported app functions, connectivity requirements, and remote-operation safeguards.

Additional Width for a Four-Person Layout

Refresh 4 increases the listed exterior width from Refresh 3's 59 inches to 70 inches. Both models have a listed exterior depth of 47 inches and height of 75 inches.

Review the final bench dimensions, heater positions, entrance opening, and usable seating space to determine whether the layout suits your intended users.

The four-person capacity does not establish equal seating comfort for every group or simultaneous reclining space for all users. Product images are illustrative, not installation or seating-clearance drawings.

Additional space beyond the exterior footprint is required for assembly, door operation, ventilation, and servicing.

Infrared Heating, Not Heated Stones

The series sheet lists full-spectrum infrared heating for Refresh 4. Confirm the actual heater types, placement, protective guards, and rated output in the approved specification.

“Full-spectrum” is a source description. Specific near-, mid-, and far-infrared coverage is not independently established here; request spectral test documentation if this is important to your purchase.

Another model's carbon-heater configuration, wattage, or warm-up claims should not be assumed to apply unchanged.

Do not pour water onto infrared heaters or electrical components. Sauna stones, a stone heater, and a steam generator are not specified.

Natural Timber Character

Hemlock is described in the supplied series materials. Confirm the exact wood species, grade, and finish for Refresh 4 in the approved specification.

Natural timber varies in color and grain and may expand, contract, or develop surface checks with changes in temperature and moisture. Follow the approved cleaning, drying, ventilation, and maintenance instructions.

Wood and other cabin surfaces can become hot. No claim is made that benches or handles prevent burns or remain permanently free from splinters.

Controls, Audio, and Lighting

The series sheet lists Wi-Fi control, Bluetooth speakers, and seven-color lighting. Confirm the actual controller, supported app, speaker quantity, and lighting configuration before ordering.

Remote heating is available only where supported by the complete system and where all manufacturer-required safety devices and procedures are in place. Inspect and prepare the cabin according to the approved instructions before any permitted remote operation.

Colored lighting is an ambiance feature, not a medical treatment. A separate therapeutic red-light capability is not established by the feature table alone.

Keep personal electronics outside the heated cabin unless specifically rated for the conditions.

Product Specifications

Specifications are based on the supplied series sheet. Confirm final dimensions, seating layout, door opening, assembly clearances, and shipping weight before ordering. The upper temperature listing is not a recommended setting for every user. No fixed warm-up time is guaranteed.

Electrical Supply and Installation

Refresh 4 is listed for 220/240 V. Do not assume compatibility with a standard 120 V household outlet or another Refresh model's power connection.

A licensed electrician must confirm the actual complete-system rating, voltage, phase, frequency, grounding, connection method, circuit protection, cable sizing, and any required residual-current protection.

The source 15 A entry does not establish breaker size, rated wattage, or permission to share a circuit with other equipment. Confirm any dedicated-circuit requirement.

Confirm whether the approved configuration uses a factory-supplied cord and plug or requires hardwiring. Do not use a travel adapter or extension lead as an installation solution.

Indoor Placement and Ventilation

Install indoors on a level, structurally adequate base, following all specified clearances. Allow space for assembly, door operation, airflow, cleaning, and servicing.

Check access routes and room dimensions before ordering. The listed 75-inch cabin height does not establish the minimum room height; additional overhead clearance may be required.

Confirm the ventilation arrangement and host-room moisture management. Vent openings alone do not establish adequate airflow.

Bathroom placement requires separate confirmation of location suitability, equipment ratings, moisture exposure, and electrical requirements. This model is not specified for outdoor installation.

Accessory and Package Confirmation

Request a complete parts schedule covering the cabin, door, benches, infrared heaters, controls, sensors, lighting, audio, ventilation, and approved power connection.

Confirm separately whether a remote control, removable bench, adjustable ceiling vent, and separate interior light are included. Another model's detailed accessory list should not be assumed to apply unchanged.

The series sheet lists an accessory called “Oxygen Bar.” Related source text describes ion generation, not an oxygen supply. Its exact function, ozone emissions, and suitability for an occupied heated cabin are not established.

Request the accessory model, instructions, and applicable emissions and safety test documentation before approving its inclusion or operation. No oxygen-enrichment, air-purification, or health benefit is claimed.

The signed quotation and approved specification determine all included items. Delivery, unloading, assembly, electrical work, and room preparation are included only when expressly listed.

Safe Use, Care, Certification, and Warranty

Follow the manufacturer's temperature and session guidance. Stay hydrated, avoid alcohol, and leave immediately if you feel dizzy, nauseated, unusually weak, or uncomfortable.

People who are pregnant, have relevant medical conditions, or take medicines affecting heat tolerance should seek medical advice before use. Children require appropriate supervision and age-specific guidance.

Keep heaters and required clearances free of towels, clothing, and other objects. Do not touch heating elements or assume that a lower cabin temperature eliminates heat-related risks.

Follow the care instructions for timber, glazing, heaters, controls, audio, and lighting. Dry and ventilate the cabin after use.

This product is intended for recreational sauna use. It is not a medical device, and no detoxification, weight-loss, pain-treatment, wound-healing, or disease-treatment benefit is claimed.

Request certification documentation for the exact complete system and components, including any ion-generating accessory. Obtain written warranty terms covering providers, coverage periods, exclusions, maintenance conditions, and claim procedures.
