A Deeper, Taller Indoor Sauna for Shared Sessions.
The Steam 4 Indoor Traditional Sauna combines a timber cabin with traditional electric heated-stone heating and a listed 4–6 person capacity.
Compared with Steam 3, this model increases the listed cabin depth and height while retaining the same exterior width. The supplied series sheet specifies a Harvia 6 kW heater, Wi-Fi control, Bluetooth audio, and seven-color mood lighting.
Despite its source model name, Steam 4 is a traditional sauna, not a dedicated steam room. A separate steam generator or infrared heating system is not specified.

Additional Depth and Height
Steam 4 increases the listed exterior depth from Steam 3's 47 inches to 60 inches and the height from 75 inches to 83 inches. Both models have a listed exterior width of 71 inches.
The product image shows a tiered seating arrangement. Review the approved drawing for bench lengths, seating depths, step access, headroom, and heater clearances.
The listed 4–6 person capacity does not establish equal seating comfort for every group or simultaneous reclining space for all users. Product images are illustrative, not installation drawings.
Natural Wood Character
Hemlock is described in the supplied series materials. Confirm the exact wood species, grade, and finish for the Steam 4 configuration before ordering.
Natural timber varies in color and grain and may expand, contract, or develop surface checks with changes in temperature and moisture. Follow the approved assembly, cleaning, drying, and maintenance instructions.
Wood surfaces can become hot. No claim is made that benches or handles remain cool, prevent burns, or are permanently free from splinters.
Traditional Heated-Stone Sauna
The electric heater warms approved sauna stones and the surrounding air. Small amounts of suitable water may be applied to the stones only where permitted by the exact heater manual, producing brief bursts of steam.
This differs from the continuous high-humidity environment of a dedicated steam room with a separate steam generator.
Follow the heater instructions for stone loading, water quality and quantity, ventilation, controls, and safety clearances. Do not pour water onto electrical components or use unapproved additives.
Wi-Fi Controls, Audio, and Lighting
The series sheet lists Wi-Fi control, Bluetooth speakers, and seven-color lighting. Confirm the actual controller, supported app, audio configuration, and lighting package in the quotation.
Remote starting or preheating is available only where supported by the supplied heater and controller and where all manufacturer-required safety devices and procedures are in place.
Confirm any required door monitoring, heater safety device, inspection procedure, and local restrictions. Never remotely start a sauna that has not been checked and prepared according to the approved instructions.
Colored lighting is an ambiance feature, not a medical treatment. Keep personal electronics outside the heated cabin unless specifically rated for the conditions.

Heater Sizing and Electrical Installation
Confirm that the actual heater is suitable for the cabin's effective heated volume, glazing, insulation, and construction. The series-listed 6 kW rating alone does not establish a guaranteed heating time.
Do not treat this sauna as a standard household-outlet appliance. It requires a suitable dedicated electrical supply and professional installation.
A licensed electrician must confirm the actual heater and complete-system ratings, voltage, phase, frequency, connection method, circuit protection, cable sizing, earthing, and any required residual-current protection.
The source 30 A listing is not a breaker-sizing instruction. Confirm whether the approved configuration requires hardwiring or uses an approved factory-supplied cord and plug.
Follow the equipment instructions and local requirements. Do not use a travel adapter or extension lead as an installation solution.
Indoor Placement and Ventilation
Install the cabin in a suitable indoor location on a level, structurally adequate base. Allow the specified space for assembly, door operation, ventilation, servicing, and heater clearances.
Check room height carefully. The listed 83-inch cabin height does not include any additional overhead clearance required for assembly, ventilation, or servicing.
Confirm cabin airflow and host-room moisture management. Vent openings alone do not establish adequate ventilation or complete humidity control.
Bathroom placement requires confirmation of equipment ratings, moisture exposure, electrical zones, and local requirements. This model is not specified for outdoor installation.
Package Confirmation
Request a complete parts schedule covering the cabin, entrance door, benches, steps or access components, heater, controls, stones, lighting, audio, bucket, and ladle.
Confirm separately whether a remote control, temperature sensor, adjustable ceiling vent, removable bench, contoured backrest, and power cord are included. Another model's detailed accessory list should not be assumed to apply unchanged.
The signed quotation and approved specification determine all included items. Electrical work, room preparation, delivery, unloading, assembly, and permits are included only when expressly listed.
Safe Use, Care, Certification, and Warranty
Follow the sauna and heater instructions. 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.
Use care when moving between seating levels. Keep access areas clear and never cover the heater or place combustible items within its required clearances.
Inspect the sauna before switching it on, including before any permitted remote operation. Dry and ventilate the cabin after use.
This product is intended for recreational sauna use, not detoxification, weight loss, color therapy, or treatment of medical conditions. It is not a medical device.
Request certification documentation for the exact cabin and components. A heater listing does not establish certification of the complete sauna.
Obtain written warranty terms, including coverage periods, responsible providers, exclusions, maintenance conditions, and claim procedures.
