Product: Medical 4 Full Spectrum Infrared Sauna by Medical Saunas™
Type: Indoor full spectrum infrared sauna for home use
Capacity: 1-2 people
Price range: Check current sale price above
Key fact: Designed by 48 doctors over 10 years. 6 heaters including 2 front-facing panels for 3D surround heat. Plugs into a standard 120V household outlet. Features silent heating, deep bench seating, interior reading light, and chromatic therapy not found in the smaller Medical 3. Built with Canadian hemlock in Los Angeles, CA.
The Medical 4 is the step up from the entry-level Medical 3. It fits 1-2 people comfortably and adds features the smaller model lacks: two front-facing heaters for full 3D surround heat, deep bench seating, a silent heating system, chromatic therapy, and an interior reading light. It was engineered by a team of 48 doctors, pain specialists, and cardiologists over a decade of research.
Like the Medical 3, it runs on a standard 120V/15A household outlet. No electrician, no special wiring. But the wider cabin (48″ × 42″ exterior vs 39″ × 36″) gives you room to stretch during solo sessions or sit beside a partner. It heats up in roughly 40 minutes and delivers therapeutic infrared energy from all directions.

Both share the same core Medical Sauna™ therapy systems. The Medical 4 adds five features that make longer daily sessions more comfortable and more effective:
3D Surround Heat with 2 Front Heaters — The the entry model heats from the sides and back only. The Medical 4 adds two front-facing panels that reach your chest, abdomen, and thighs directly. More uniform coverage means faster, deeper heating across the full body.
Deep Bench Seating — Wider, deeper bench for 30-45 minute sessions without pressure points. Matters a lot for daily use.
Silent Heating System™ — Quieter heater design. If you meditate, read, or listen to music during sessions, you won't hear the heaters cycling on and off.
Interior Reading Light System™ — A dedicated light inside the cabin. Useful if you sauna in a dimly lit room or want to read during sessions.
Chromatic Therapy System™ — Color light therapy that cycles through wavelengths studied for mood, skin health, and relaxation benefits. Both models have mood lighting, but only the Medical 4 adds this dedicated therapy mode.
Built with natural Canadian hemlock, selected after years of testing for its strength and health properties. Hemlock hardens with age, making the sauna more durable over time. Its natural astringent qualities help cleanse skin during sessions, complementing the infrared detox effect. The wood puts off a clean, natural scent when heated.
Most infrared saunas need 90 minutes to 2 hours to preheat. The Medical 4 reaches full temperature in about 40 minutes. You get more therapeutic time per session, lower electricity draw, and the ability to do hot/cold therapy rounds. Step out, cool down, return to a fully heated cabin within minutes. The rapid heat-up also simulates the body's response to exercise, boosting heat tolerance and immune function over time.
Six heaters positioned around the cabin, including two front-facing panels, deliver infrared energy from every direction. Far infrared waves penetrate deep into tissue and cells. This helps relieve sore muscles, increase range of motion, reduce spasms, and lower pain. The front heaters are the key differentiator from the the entry model, which only heats from the sides and back.
The Medical 4's heaters emit near-infrared, mid-infrared, and far-infrared wavelengths simultaneously. Near-infrared targets skin and surface tissue. Mid-infrared penetrates into soft tissue and joints. Far-infrared raises core body temperature for cardiovascular and detox benefits. Most budget saunas only offer a single wavelength. Full spectrum coverage means you get the widest range of therapeutic effects in every session.
Sustained infrared heat opens pores and drives out accumulated toxins: BPA from household plastics, heavy metals, phthalates from processed foods, and nicotine. Following the Detox Routine™ protocol with consistent daily sessions delivers a level of detoxification that surface-heat saunas cannot match.
After a session, the cabin's airflow design releases heat gradually. Your body cools at a safe, controlled pace instead of the abrupt temperature drop you get with poorly designed saunas. This reduces dizziness risk and supports healthy recovery.
The Medical 4's double-wall insulation keeps cabin temperature consistent with minimal energy draw. Once it reaches operating temperature, the heaters cycle less frequently, keeping electricity costs lower during long sessions.
The Medical 4 sits between the compact the entry model and the wider Medical 5. It fits you if:
Too big? The Medical 3 fits one person in a 39″ × 36″ footprint on the same 120V plug. Need more room? The Medical 5 fits 2-3 people with 9 heaters, but requires a 120V/35A circuit (two plugs).
Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The team works directly with medical doctors, cardiologists, and pain specialists at every stage. No outsourced manufacturing. Every unit ships direct from LA.
Medical Saunas™ only lists health benefits supported by published clinical studies. The Medical Sauna Series™ took 10 years to develop with input from 48 medical professionals. Each feature was chosen for its measured health impact. Daily infrared sauna use has been studied for cardiovascular support, immune function, pain reduction, and full-body detoxification.

No. It runs on a standard 120V/15A household outlet with a 1-120VAC/15AMP plug. No electrician or dedicated circuit required. The Medical 4 is the largest model in the Medical Sauna Series that still uses a standard outlet. The Medical 5 and above need higher amperage circuits.
The Medical 4 fits 1-2 people. The interior is 44 inches wide and 38 inches deep with a deep bench seat. One person sits very comfortably with room to spare. Two adults can sit side-by-side, though it may feel snug for larger individuals.

Far-infrared penetrates deepest, raising core body temperature for cardiovascular and detox benefits. Most budget saunas only produce far-infrared. Full spectrum gives you the widest therapeutic range per session.

Product: Medical 4 Full Spectrum Infrared Sauna by Medical Saunas™
Type: Indoor full spectrum infrared sauna for home use
Capacity: 1-2 people
Price range: Check current sale price above
Key fact: Designed by 48 doctors over 10 years. 6 heaters including 2 front-facing panels for 3D surround heat. Plugs into a standard 120V household outlet. Features silent heating, deep bench seating, interior reading light, and chromatic therapy not found in the smaller Medical 3. Built with Canadian hemlock in Los Angeles, CA.
The Medical 4 is the step up from the entry-level Medical 3. It fits 1-2 people comfortably and adds features the smaller model lacks: two front-facing heaters for full 3D surround heat, deep bench seating, a silent heating system, chromatic therapy, and an interior reading light. It was engineered by a team of 48 doctors, pain specialists, and cardiologists over a decade of research.
Like the Medical 3, it runs on a standard 120V/15A household outlet. No electrician, no special wiring. But the wider cabin (48″ × 42″ exterior vs 39″ × 36″) gives you room to stretch during solo sessions or sit beside a partner. It heats up in roughly 40 minutes and delivers therapeutic infrared energy from all directions.
| Capacity | 1-2 People |
| Heaters | 6 Ultra Full Spectrum Red Light Heaters™ (includes 2 front-facing panels) |
| Interior Dimensions (W×D×H) | 44″ × 38″ × 69″ |
| Exterior Dimensions (W×D×H) | 48″ × 42″ × 75″ |
| Operating Voltage | 120V / 15 Amp |
| Plug Type | 1-120VAC / 15AMP (standard household outlet) |
| Wattage | 1,700W |
| Weight | 405 lbs |
| Construction | Natural Canadian Hemlock Wood |
| Assembly | Clasp-together, no tools needed (2 people recommended) |
| Door | Tempered Glass |
| Warranty | 3 Years (Labor + Parts + Structure) included free |
Both share the same core Medical Sauna™ therapy systems. The Medical 4 adds five features that make longer daily sessions more comfortable and more effective:
3D Surround Heat with 2 Front Heaters — The the entry model heats from the sides and back only. The Medical 4 adds two front-facing panels that reach your chest, abdomen, and thighs directly. More uniform coverage means faster, deeper heating across the full body.
Deep Bench Seating — Wider, deeper bench for 30-45 minute sessions without pressure points. Matters a lot for daily use.
Silent Heating System™ — Quieter heater design. If you meditate, read, or listen to music during sessions, you won't hear the heaters cycling on and off.
Interior Reading Light System™ — A dedicated light inside the cabin. Useful if you sauna in a dimly lit room or want to read during sessions.
Chromatic Therapy System™ — Color light therapy that cycles through wavelengths studied for mood, skin health, and relaxation benefits. Both models have mood lighting, but only the Medical 4 adds this dedicated therapy mode.
Built with natural Canadian hemlock, selected after years of testing for its strength and health properties. Hemlock hardens with age, making the sauna more durable over time. Its natural astringent qualities help cleanse skin during sessions, complementing the infrared detox effect. The wood puts off a clean, natural scent when heated.
Most infrared saunas need 90 minutes to 2 hours to preheat. The Medical 4 reaches full temperature in about 40 minutes. You get more therapeutic time per session, lower electricity draw, and the ability to do hot/cold therapy rounds. Step out, cool down, return to a fully heated cabin within minutes. The rapid heat-up also simulates the body's response to exercise, boosting heat tolerance and immune function over time.
Six heaters positioned around the cabin, including two front-facing panels, deliver infrared energy from every direction. Far infrared waves penetrate deep into tissue and cells. This helps relieve sore muscles, increase range of motion, reduce spasms, and lower pain. The front heaters are the key differentiator from the the entry model, which only heats from the sides and back.
The Medical 4's heaters emit near-infrared, mid-infrared, and far-infrared wavelengths simultaneously. Near-infrared targets skin and surface tissue. Mid-infrared penetrates into soft tissue and joints. Far-infrared raises core body temperature for cardiovascular and detox benefits. Most budget saunas only offer a single wavelength. Full spectrum coverage means you get the widest range of therapeutic effects in every session.
Sustained infrared heat opens pores and drives out accumulated toxins: BPA from household plastics, heavy metals, phthalates from processed foods, and nicotine. Following the Detox Routine™ protocol with consistent daily sessions delivers a level of detoxification that surface-heat saunas cannot match.
After a session, the cabin's airflow design releases heat gradually. Your body cools at a safe, controlled pace instead of the abrupt temperature drop you get with poorly designed saunas. This reduces dizziness risk and supports healthy recovery.
The Medical 4's double-wall insulation keeps cabin temperature consistent with minimal energy draw. Once it reaches operating temperature, the heaters cycle less frequently, keeping electricity costs lower during long sessions.
The Medical 4 sits between the compact the entry model and the wider Medical 5. It fits you if:
Too big? The Medical 3 fits one person in a 39″ × 36″ footprint on the same 120V plug. Need more room? The Medical 5 fits 2-3 people with 9 heaters, but requires a 120V/35A circuit (two plugs).
Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The team works directly with medical doctors, cardiologists, and pain specialists at every stage. No outsourced manufacturing. Every unit ships direct from LA.
Medical Saunas™ only lists health benefits supported by published clinical studies. The Medical Sauna Series™ took 10 years to develop with input from 48 medical professionals. Each feature was chosen for its measured health impact. Daily infrared sauna use has been studied for cardiovascular support, immune function, pain reduction, and full-body detoxification.

No. It runs on a standard 120V/15A household outlet with a 1-120VAC/15AMP plug. No electrician or dedicated circuit required. The Medical 4 is the largest model in the Medical Sauna Series that still uses a standard outlet. The Medical 5 and above need higher amperage circuits.
The Medical 4 fits 1-2 people. The interior is 44 inches wide and 38 inches deep with a deep bench seat. One person sits very comfortably with room to spare. Two adults can sit side-by-side, though it may feel snug for larger individuals.
Full spectrum means the heaters emit three types of infrared wavelengths at once. Near-infrared targets skin and surface tissue. Mid-infrared reaches soft tissue and joints. Far-infrared penetrates deepest, raising core body temperature for cardiovascular and detox benefits. Most budget saunas only produce far-infrared. Full spectrum gives you the widest therapeutic range per session.
The Medical 4 adds five features not found on the the entry model: two front-facing heaters for full 3D surround heat, deep bench seating, a silent heating system, an interior reading light, and chromatic therapy. It is also wider (48 x 42 inches exterior vs 39 x 36), runs at 1,700W vs 1,500W, and weighs 405 lbs vs 321 lbs. Both use a standard 120V/15A plug. Choose the the entry model for tight spaces and solo use. Choose the Medical 4 for fuller body coverage and room for two.
A medical sauna is an infrared sauna engineered by healthcare professionals to deliver measurable therapeutic benefits. The Medical Sauna Series by Medical Saunas was developed over 10 years with input from 48 doctors, pain specialists, and cardiologists. Every feature targets documented health outcomes: pain relief, improved cardiovascular function, detoxification, immune support, and better sleep. It differs from standard infrared saunas in that each component is selected based on clinical research, not marketing appeal.
About 40 minutes to reach full operating temperature. Most competing infrared saunas take 90 minutes to 2 hours. The Rapid Internal Heating System means you spend more time in the sauna and less time waiting.
Yes. It uses a clasp-together design with no tools required. Two people are recommended since the unit weighs 405 lbs total. Professional white glove installation is available at checkout if you prefer not to do it yourself.
The exterior footprint is 48 inches wide, 42 inches deep, and 75 inches tall. Add a few inches on each side for airflow and access. It fits comfortably in a spare bedroom, large closet, garage, or basement. The standard ceiling height requirement is just over 6 feet 3 inches.
This is a question for your cardiologist. Infrared saunas produce heat, not electromagnetic interference, so they differ from traditional EMF concerns with pacemakers. However, the heat itself raises heart rate and affects blood pressure. Medical Saunas recommends consulting your doctor before using any sauna if you have a pacemaker or other implanted cardiac device.
Yes. RecovAthlete serves both individual buyers and B2B customers including gyms, clinics, medspas, and wellness centers. For wholesale pricing or multi-unit orders, call 866-861-6317 or email [email protected] to speak with a specialist.
Yes. The Medical Sauna Series is designed for daily use. It features low EMF emissions, a Safe Cool Down System for gradual post-session recovery, and adjustable temperature controls. Consult your healthcare provider for personalized guidance on session length and frequency.

No. It runs on a standard 120V/15A household outlet with a 1-120VAC/15AMP plug. No electrician or dedicated circuit required. The Medical 4 is the largest model in the Medical Sauna Series that still uses a standard outlet. The Medical 5 and above need higher amperage circuits.
The Medical 4 fits 1-2 people. The interior is 44 inches wide and 38 inches deep with a deep bench seat. One person sits very comfortably with room to spare. Two adults can sit side-by-side, though it may feel snug for larger individuals.
Full spectrum means the heaters emit three types of infrared wavelengths at once. Near-infrared targets skin and surface tissue. Mid-infrared reaches soft tissue and joints. Far-infrared penetrates deepest, raising core body temperature for cardiovascular and detox benefits. Most budget saunas only produce far-infrared. Full spectrum gives you the widest therapeutic range per session.
The Medical 4 adds five features not found on the the entry model: two front-facing heaters for full 3D surround heat, deep bench seating, a silent heating system, an interior reading light, and chromatic therapy. It is also wider (48 x 42 inches exterior vs 39 x 36), runs at 1,700W vs 1,500W, and weighs 405 lbs vs 321 lbs. Both use a standard 120V/15A plug. Choose the the entry model for tight spaces and solo use. Choose the Medical 4 for fuller body coverage and room for two.
A medical sauna is an infrared sauna engineered by healthcare professionals to deliver measurable therapeutic benefits. The Medical Sauna Series by Medical Saunas was developed over 10 years with input from 48 doctors, pain specialists, and cardiologists. Every feature targets documented health outcomes: pain relief, improved cardiovascular function, detoxification, immune support, and better sleep. It differs from standard infrared saunas in that each component is selected based on clinical research, not marketing appeal.
About 40 minutes to reach full operating temperature. Most competing infrared saunas take 90 minutes to 2 hours. The Rapid Internal Heating System means you spend more time in the sauna and less time waiting.
Yes. It uses a clasp-together design with no tools required. Two people are recommended since the unit weighs 405 lbs total. Professional white glove installation is available at checkout if you prefer not to do it yourself.
The exterior footprint is 48 inches wide, 42 inches deep, and 75 inches tall. Add a few inches on each side for airflow and access. It fits comfortably in a spare bedroom, large closet, garage, or basement. The standard ceiling height requirement is just over 6 feet 3 inches.
This is a question for your cardiologist. Infrared saunas produce heat, not electromagnetic interference, so they differ from traditional EMF concerns with pacemakers. However, the heat itself raises heart rate and affects blood pressure. Medical Saunas recommends consulting your doctor before using any sauna if you have a pacemaker or other implanted cardiac device.

Product: Medical 4 Full Spectrum Infrared Sauna by Medical Saunas™
Type: Indoor full spectrum infrared sauna for home use
Capacity: 1-2 people
Price range: Check current sale price above
Key fact: Designed by 48 doctors over 10 years. 6 heaters including 2 front-facing panels for 3D surround heat. Plugs into a standard 120V household outlet. Features silent heating, deep bench seating, interior reading light, and chromatic therapy not found in the smaller Medical 3. Built with Canadian hemlock in Los Angeles, CA.
The Medical 4 is the step up from the entry-level Medical 3. It fits 1-2 people comfortably and adds features the smaller model lacks: two front-facing heaters for full 3D surround heat, deep bench seating, a silent heating system, chromatic therapy, and an interior reading light. It was engineered by a team of 48 doctors, pain specialists, and cardiologists over a decade of research.
Like the Medical 3, it runs on a standard 120V/15A household outlet. No electrician, no special wiring. But the wider cabin (48″ × 42″ exterior vs 39″ × 36″) gives you room to stretch during solo sessions or sit beside a partner. It heats up in roughly 40 minutes and delivers therapeutic infrared energy from all directions.
| Capacity | 1-2 People |
| Heaters | 6 Ultra Full Spectrum Red Light Heaters™ (includes 2 front-facing panels) |
| Interior Dimensions (W×D×H) | 44″ × 38″ × 69″ |
| Exterior Dimensions (W×D×H) | 48″ × 42″ × 75″ |
| Operating Voltage | 120V / 15 Amp |
| Plug Type | 1-120VAC / 15AMP (standard household outlet) |
| Wattage | 1,700W |
| Weight | 405 lbs |
| Construction | Natural Canadian Hemlock Wood |
| Assembly | Clasp-together, no tools needed (2 people recommended) |
| Door | Tempered Glass |
| Warranty | 3 Years (Labor + Parts + Structure) included free |
Both share the same core Medical Sauna™ therapy systems. The Medical 4 adds five features that make longer daily sessions more comfortable and more effective:
3D Surround Heat with 2 Front Heaters — The the entry model heats from the sides and back only. The Medical 4 adds two front-facing panels that reach your chest, abdomen, and thighs directly. More uniform coverage means faster, deeper heating across the full body.
Deep Bench Seating — Wider, deeper bench for 30-45 minute sessions without pressure points. Matters a lot for daily use.
Silent Heating System™ — Quieter heater design. If you meditate, read, or listen to music during sessions, you won't hear the heaters cycling on and off.
Interior Reading Light System™ — A dedicated light inside the cabin. Useful if you sauna in a dimly lit room or want to read during sessions.
Chromatic Therapy System™ — Color light therapy that cycles through wavelengths studied for mood, skin health, and relaxation benefits. Both models have mood lighting, but only the Medical 4 adds this dedicated therapy mode.
Built with natural Canadian hemlock, selected after years of testing for its strength and health properties. Hemlock hardens with age, making the sauna more durable over time. Its natural astringent qualities help cleanse skin during sessions, complementing the infrared detox effect. The wood puts off a clean, natural scent when heated.
Most infrared saunas need 90 minutes to 2 hours to preheat. The Medical 4 reaches full temperature in about 40 minutes. You get more therapeutic time per session, lower electricity draw, and the ability to do hot/cold therapy rounds. Step out, cool down, return to a fully heated cabin within minutes. The rapid heat-up also simulates the body's response to exercise, boosting heat tolerance and immune function over time.
Six heaters positioned around the cabin, including two front-facing panels, deliver infrared energy from every direction. Far infrared waves penetrate deep into tissue and cells. This helps relieve sore muscles, increase range of motion, reduce spasms, and lower pain. The front heaters are the key differentiator from the the entry model, which only heats from the sides and back.
The Medical 4's heaters emit near-infrared, mid-infrared, and far-infrared wavelengths simultaneously. Near-infrared targets skin and surface tissue. Mid-infrared penetrates into soft tissue and joints. Far-infrared raises core body temperature for cardiovascular and detox benefits. Most budget saunas only offer a single wavelength. Full spectrum coverage means you get the widest range of therapeutic effects in every session.
Sustained infrared heat opens pores and drives out accumulated toxins: BPA from household plastics, heavy metals, phthalates from processed foods, and nicotine. Following the Detox Routine™ protocol with consistent daily sessions delivers a level of detoxification that surface-heat saunas cannot match.
After a session, the cabin's airflow design releases heat gradually. Your body cools at a safe, controlled pace instead of the abrupt temperature drop you get with poorly designed saunas. This reduces dizziness risk and supports healthy recovery.
The Medical 4's double-wall insulation keeps cabin temperature consistent with minimal energy draw. Once it reaches operating temperature, the heaters cycle less frequently, keeping electricity costs lower during long sessions.
The Medical 4 sits between the compact the entry model and the wider Medical 5. It fits you if:
Too big? The Medical 3 fits one person in a 39″ × 36″ footprint on the same 120V plug. Need more room? The Medical 5 fits 2-3 people with 9 heaters, but requires a 120V/35A circuit (two plugs).
Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The team works directly with medical doctors, cardiologists, and pain specialists at every stage. No outsourced manufacturing. Every unit ships direct from LA.
Medical Saunas™ only lists health benefits supported by published clinical studies. The Medical Sauna Series™ took 10 years to develop with input from 48 medical professionals. Each feature was chosen for its measured health impact. Daily infrared sauna use has been studied for cardiovascular support, immune function, pain reduction, and full-body detoxification.

The Medical Breakthrough series of massage chairs are warranted against defects in materials and workmanship under typical residential use for a period of three (3) years from the date of receipt by the original end-user consumer.
This is a parts warranty. Replacement parts for covered defects are provided at no charge during the warranty period. Service and labor costs are not included and would be charged separately if a technician visit is required.
This warranty applies to the original end-user consumer purchasing for personal, residential use. It is non-transferable. Chairs used in commercial environments — health clubs, clinics, spas, or any multi-user setting — are not covered under the residential warranty terms. Contact us at 866-861-6317 before purchasing for commercial use to discuss coverage options.
If your Medical Breakthrough massage chair develops a defect covered under warranty, follow these steps:
The 3-year warranty covers the cost of replacement parts only. If a technician is needed to install parts or diagnose an issue on-site, those service and labor fees are billed separately and are not covered by the warranty. We will always provide a cost estimate before any technician work is scheduled.
