Medical Saunas

Medical Saunas is an American wellness brand engineered by a team of 48 doctors and engineers, manufacturing doctor-designed infrared saunas, traditional steam saunas, outdoor saunas, commercial saunas, and Frozen Cold Plunge cold therapy systems. Headquartered in Los Angeles with hand-assembly at the company's California factory, Medical Saunas develops every product in collaboration with cardiologists, pain specialists, chiropractors, and physical therapists — positioning the brand around evidence-based heat and cold therapy rather than the unverified wellness claims common in the broader sauna category.

The Trade Table carries the full Medical Saunas catalog including the Medical 3, 4, 4 Spectrum, 5, 6, and 7 Plus indoor infrared models; the Traditional 4, 5, 6, 7, 8 Plus, and Traditional X steam saunas; the Nature 4, 5, 6, 6 Flatroof, 7, X, and X Combo outdoor configurations; the Custom Sauna made-to-order series for non-standard layouts; the Commercial Sauna 485-489 Plus and Commercial Spa 485-489 Customized B2B systems; and the Frozen 1 through Frozen 9 Cold Plunge series.

Medical Saunas | Doctor-Designed Saunas, Cold Plunges & Commercial Wellness Systems

A Medical Saunas product combines doctor-led engineering, premium construction materials, hand-assembly in the United States, and a coordinated heat-or-cold therapy modality designed for daily home, commercial, or therapeutic use. The company's product engineering process involves 48 medical professionals — cardiologists, pain specialists, chiropractors, nurse practitioners, massage therapists, physical therapists, nutritionists, and surgeons — who advise on heating system design, body coverage, session duration, safety features, and feature selection. This medical advisory model distinguishes Medical Saunas from competitors that design around aesthetic and price targets rather than therapeutic outcomes.

The Medical Series represents the core indoor infrared lineup — Medical 3, 4, 4 Spectrum, 5, 6, and 7 Plus, named for the maximum number of users each model accommodates. The Medical 3 fits one to three users in a compact footprint suitable for smaller homes, master suites, and dedicated wellness rooms. The Medical 4 and 4 Spectrum expand capacity for couples and small families, with the Spectrum variant adding full-spectrum infrared heating across near, mid, and far wavelengths. The Medical 5 and 6 deliver larger family configurations with corner and rectangular layouts, while the Medical 7 Plus serves as the flagship indoor model for larger households and small commercial installations.

The Traditional Series — Traditional 4, 5, 6, 7, 8 Plus, and Traditional X — covers the brand's traditional steam sauna lineup, delivering the classic Finnish sauna experience with elevated air temperatures (175-195°F), sauna stones, and steam from water poured on hot rocks. These models suit buyers who prefer the higher-temperature traditional sauna environment over the radiant infrared modality. The Traditional X serves as the premium flagship of the steam lineup, while the Traditional 4 through 8 Plus models scale by user capacity.

The Nature Series — Nature 4, 5, 6, 6 Flatroof, 7, X, and X Combo — extends the Medical Saunas lineup to outdoor sauna installations. These models are engineered for backyard, patio, and pool deck installations with weather-resistant construction and outdoor-rated electrical systems. The Nature 6 Flatroof variant accommodates patio installations with low overhead clearance requirements. The Nature X and Nature X Combo represent the flagship outdoor configurations, with the Combo variant integrating both infrared and traditional heating modalities in a single outdoor unit.

The Custom Sauna Series — Custom Sauna, Custom Sauna 1, 2, 3, 4-5, 6-9, and Custom Sauna-beta — addresses non-standard installation requirements where stock product dimensions don't fit the available space. These made-to-order configurations let buyers specify dimensions, layout, wood selection, and feature integration for new construction, finished basement conversions, and architectural remodel projects requiring specific sauna-room dimensions.

The Commercial Sauna Series — Commercial Sauna 485, 486, 487, 488, and 489 Plus — and the Commercial Spa Series — Commercial Spa 485, 486, 487, 488, and 489 Customized — cover B2B installations for gyms, wellness centers, hotels, spas, athletic recovery facilities, and physical therapy clinics. Commercial models are engineered for 15 hours of daily use, 365 days a year, with reinforced construction, heavy-duty heating systems, and extended electrical specifications. The Commercial Spa Customized variants offer additional specification options for buyers requiring dimensional and feature customization on top of the heavy-duty commercial chassis.

The Frozen Cold Plunge Series — Frozen 1 through Frozen 9 Cold Plunge — adds cold water immersion therapy to the Medical Saunas lineup, enabling complete hot/cold contrast therapy routines from a single brand. Each Frozen model maintains water temperature between 37°F (just above freezing) and approximately 72°F (room temperature), runs on a standard 120V 15-amp household outlet, includes UV sanitizing and self-cleaning filtration, and operates with the energy efficiency of a mini fridge. Frozen units are patent-pending with military-grade insulation in both the outer and inner tank, integrated equipment housing for safety, and an optional steam generator and essential oil infuser configuration.

Medical Saunas backs its full product lineup with hand-assembly quality control from the Los Angeles factory, US-based customer service, a network of 581 service technicians across the US and Canada, a 3-year limited warranty on residential cold plunges and saunas, and a 1-year limited warranty on commercial installations.

Medical Saunas FAQs

What product series does Medical Saunas offer?

Medical Saunas manufactures seven distinct product series — Medical (indoor infrared, models 3 through 7 Plus including the 4 Spectrum), Traditional (indoor steam, models 4 through 8 Plus and Traditional X), Nature (outdoor, models 4 through X and X Combo), Custom Sauna (made-to-order configurations), Commercial Sauna (B2B models 485 through 489 Plus), Commercial Spa (customized B2B models 485 through 489), and Frozen Cold Plunge (cold therapy models 1 through 9). The full lineup covers residential, commercial, and custom installation applications across both heat therapy and cold therapy modalities.

What is a Frozen Cold Plunge?

The Frozen Cold Plunge is Medical Saunas' patent-pending cold water immersion system, available in nine sizes from Frozen 1 through Frozen 9. Each unit maintains water temperature between 37°F and approximately 72°F using built-in chiller technology, runs on a standard 120V 15-amp household outlet, and includes UV sanitizing plus self-cleaning filtration. The integrated equipment housing eliminates external chillers and exposed lines for a cleaner installation. Optional configurations include a steam generator and essential oil infuser. Frozen units are designed for daily hot/cold contrast therapy when paired with a Medical Saunas heat therapy unit.

Which Medical Saunas product is right for me?

Match the product series to your application. For indoor infrared heat therapy, choose the Medical 3, 4, 4 Spectrum, 5, 6, or 7 Plus based on user capacity. For traditional Finnish-style steam sauna, choose the Traditional 4 through 8 Plus or Traditional X. For outdoor backyard installation, choose the Nature 4 through X Combo. For non-standard dimensions or architectural integration, choose the Custom Sauna series. For commercial gym, spa, or wellness center installations, choose the Commercial Sauna 485-489 Plus or Commercial Spa Customized series. For cold water immersion therapy, choose the Frozen 1 through Frozen 9 based on user capacity and footprint requirements.

What is the difference between infrared, traditional, and hybrid Medical Saunas?

Infrared Medical Saunas (Medical Series and Nature Series) use radiant infrared heaters to warm the body directly without significantly heating ambient air, typically operating at 120-140°F with focused body penetration. Traditional Medical Saunas (Traditional Series) use sauna stoves and stones to heat ambient air to 175-195°F, with steam produced when water is poured on hot stones for the classic Finnish sauna experience. The Nature X Combo combines infrared and traditional heating modalities in a single outdoor unit — letting users choose between modalities or use both in coordinated sessions.

Where are Medical Saunas products made?

Medical Saunas products are designed, developed, and hand-assembled in the United States at the company's Los Angeles, California factory. The company manages production internally without overseas contract manufacturing, supporting consistent quality control and warranty support. This domestic manufacturing positions Medical Saunas differently from the majority of saunas and cold plunges in the residential market, which are typically manufactured overseas and imported.

What warranty does Medical Saunas provide?

Medical Saunas residential saunas and Frozen Cold Plunge units carry a 3-year limited warranty. Commercial Sauna and Commercial Spa units used in B2B installations carry a 1-year limited warranty due to the heavier commercial duty cycle. The brand maintains a network of 581 service technicians across the United States and Canada to handle installation, warranty service, and repair work without requiring customer-performed repairs.

Can I use a Medical Saunas residential model in a commercial setting?

No. Residential and commercial Medical Saunas products are engineered to different duty cycles. Residential saunas are designed for daily home use by household members. Commercial Sauna and Commercial Spa models are reinforced for 15-hour daily use, 365 days a year, with heavy-duty heating systems, reinforced construction, and warranty terms specifically covering commercial duty. Using a residential model in a commercial application typically voids the warranty and accelerates wear. For commercial gym, spa, hotel, and wellness center installations, select from the Commercial Sauna 485-489 Plus or Commercial Spa Customized series.

How much electrical capacity does a Frozen Cold Plunge need?

Frozen Cold Plunge units operate on a standard 120V 15-amp household electrical outlet — the same circuit type used for most household appliances. No dedicated 240V circuit is required. The chiller system is engineered for energy efficiency comparable to a mini fridge, allowing daily operation without significant electrical cost impact. Always verify circuit capacity with your installation electrician based on your specific home wiring.

What does Custom Sauna mean?

The Custom Sauna series — Custom Sauna 1 through Custom Sauna 6-9 — covers Medical Saunas' made-to-order configurations for installations where stock product dimensions don't fit the available space. Buyers specify dimensions, layout, and feature integration for projects like new construction wellness rooms, finished basement conversions with non-standard ceiling heights, architectural remodels with specific sauna room dimensions, and custom retreat installations. Custom Sauna lead times and pricing differ from stock product configurations — contact The Trade Table for specifications and quote requests.
