Create a comfortable home wellness retreat with the Medical Saunas Medical 4, a premium 1–2 person full-spectrum infrared sauna combining six strategically positioned heaters, natural hemlock construction, deep bench seating, integrated lighting, and modern entertainment features.
Designed for couples or individual users who want additional room to relax, the Medical 4 provides a comfortable 44" × 38" interior while maintaining a relatively compact 48" × 42" exterior footprint.
A total of six Ultra Full Spectrum Red Light Heaters™ provide approximately 1,700 watts of heating power, including two front-facing heaters designed to provide warmth from multiple directions throughout the cabin.
Medical Saunas' Rapid Internal Heating System™ is engineered to bring the cabin up to temperature efficiently, while the Insulated Airflow System™ helps retain heat and maintain a more consistent sauna environment throughout your session.
Natural hemlock construction, deep bench seating, integrated controls, Bluetooth audio, chromatic lighting, a reading light, tempered glass door, and silent infrared heating complete a sauna designed for convenient everyday use in premium home wellness spaces.
Comfortable 1–2 Person Interior
The Medical 4 is designed to accommodate approximately one to two people.
Its interior measures approximately 44" W × 38" D × 69" H, providing comfortable room for a couple while giving an individual user substantially more space than a compact personal sauna.
This makes the Medical 4 particularly well suited to users who want a shared sauna without moving into the significantly larger footprint of the Medical 5 or Medical 6.
Six Full-Spectrum Infrared Heaters
The Medical 4 incorporates six Ultra Full Spectrum Red Light Heaters™ positioned throughout the cabin.
The heater layout includes two front-facing heaters, helping provide infrared warmth from multiple directions instead of concentrating the heating system exclusively behind the seated user.
1,700W Heating System
The six-heater system provides approximately 1,700 watts of total heating power.
The Medical 4 operates from a 120V / 15A electrical connection, allowing the current configuration to operate without the higher-amperage or dual-circuit requirements of larger models in the Medical Sauna series.
3D Surround Heat with Front Heaters
Two front-facing heaters complement the other infrared heating surfaces to create Medical Saunas' multi-directional heating design.
This arrangement helps distribute warmth across more of the seating area and provides a more enveloping infrared sauna environment.
Rapid Internal Heating System™
Medical Saunas' Rapid Internal Heating System™ is designed to bring the sauna up to operating temperature efficiently.
Combined with the insulated cabin construction, the heating system helps reduce unnecessary warm-up time while maintaining consistent conditions throughout your session.
Insulated Airflow System™
The Insulated Airflow System™ helps manage ventilation while retaining the heat required for a comfortable infrared sauna environment.
Effective insulation and controlled airflow help reduce unnecessary temperature fluctuations throughout the session.
Natural Hemlock Construction
The Medical 4 is constructed from natural hemlock wood, creating the warm appearance and atmosphere associated with premium home saunas.
Hemlock provides a durable structural material well suited to the repeated heating and cooling cycles associated with regular sauna use.
Deep Bench Seating
The Medical 4 incorporates deep bench seating designed to provide a comfortable seated position during longer relaxation sessions.
The wider cabin allows two users to sit together while providing additional room when the sauna is being used individually.
Silent Infrared Heating
The Silent Heating System™ provides infrared warmth without relying on the blower noise associated with many conventional forced-air heating systems.
This contributes to a quieter environment for relaxing, reading, or listening to audio during your session.
Chromatic Lighting
The integrated Chromatic Therapy System™ provides selectable colored lighting so you can customize the atmosphere inside the cabin.
Choose a preferred lighting environment for relaxation or use the dedicated reading light when additional illumination is desired.
Integrated Bluetooth Audio
Built-in speakers and Bluetooth functionality allow compatible devices to provide music, podcasts, or other audio during sauna sessions.
Additional MP3 connectivity provides another option for compatible audio sources.
