Planning installation correctly before the unit arrives avoids costly adjustments and keeps setup on schedule.
Infrared Model Dimensions And Electrical
The Medical 5™ carries exterior dimensions of 63" x 42" x 75" and weighs 505 lbs. It runs on a standard 120V/35amp connection, requiring no hardwired electrical work for most home setups. This makes it one of the more accessible 3 person home sauna options for households without existing 220V infrastructure.
Traditional Model Dimensions And Electrical
The Traditional 6™ has exterior dimensions of 60" x 55.1" x 74.8" and weighs 821 lbs. It requires a 220V-240V/40amp hardwired connection with a 120V plug for lights. A licensed electrician should assess panel capacity and run the dedicated circuit before the unit arrives.
Room Selection And Surface Requirements
Both 3-person models are well-suited for dedicated wellness rooms, large home gyms, and basement installations. Concrete slab and tile over concrete are the most practical flooring choices. Plan for 18 to 24 inches of clearance on the door side and a minimum ceiling height of 7 feet.
Clearance And Assembly
Plan for a minimum of 18 to 24 inches of clearance on the door side of both units for safe entry and exit. The Medical 5™ uses a clasp-together assembly requiring no professional installation. The Traditional 6™ requires a hardwired electrical setup but does not require structural modifications to the room itself.
Features That Define A Medical-Grade Three-Person Sauna
The specifications inside a three person sauna determine whether it performs at a medical-grade level or simply looks like one.
Doctor-Informed Design, From Heater To Hardware
Our lineup is developed with input from over 48 doctors, pain specialists, and cardiologists. Every feature, from heater placement to temperature parameters to wood selection, reflects clinical thinking rather than market trends. This is what separates a Medical Saunas™ unit from alternatives backed by empty wellness claims.
Insulated Airflow For Consistent Temperature Distribution
The Insulated Airflow System™ keeps internal temperatures stable across the full enclosure. In a 3-person unit, consistent distribution matters more than in a single-person model. Poorly insulated saunas cycle heat unevenly, reducing session quality for users seated away from the heater.
Natural Hemlock Engineered For Decades Of Use
100% natural Canadian hemlock is standard across our Medical Series and Traditional Series 3-person models, handcrafted in the USA for long-term performance. Instead of degrading with age, hemlock hardens. Engineered wood composites used in lower-grade saunas absorb moisture, expand, and weaken with repeated heat and steam exposure in ways that natural hemlock does not.
Safety Engineering Built Into Every Unit
Our trusty Safe Cool Down System™, high-heat-rated tempered glass door, protective heater covers, and high-heat-tolerance electronics are all standard. In a shared-use enclosure, safety engineering is not a premium add-on. Our doctor-informed design process treats it as a baseline requirement.
