Product: Nature 8 Plus Hybrid Outdoor Sauna by Medical Saunas™

Type: Flagship hybrid outdoor sauna: dry infrared + traditional steam, Executive SPA Design

Capacity: 4-6 people

Price range: Check current sale price above

Key fact: The most powerful outdoor sauna ever built. Designed by 48 doctors. 11 Ultra Full Spectrum Outdoor Heaters (100X Stronger) at 4,000W plus an 8,000W traditional steam stove (12,000W total). Executive SPA Design with Extra-Rapid Heating and Extra-Insulated Airflow, both exclusive to this model. Natural cedar construction. Requires 220V/50A hardwired electrical. 1,614 lbs. Hand-assembled in Los Angeles, CA.

Nature 8 Plus Outdoor Sauna: 4-6 Person Flagship Hybrid, 12,000W

The Nature 8 Plus is the flagship of the entire Nature Series and the most powerful outdoor sauna Medical Saunas has ever built. It seats 4-6 people in an Executive SPA Design, runs 11 full spectrum infrared heaters at 4,000W alongside an 8,000W traditional steam stove, and includes every feature in the Nature lineup plus three exclusives found only at this tier.

At 12,000W combined output, this sauna delivers more thermal power than many commercial installations. The Executive SPA Design, Extra-Rapid Internal Heating, and Extra-Insulated Airflow are features the Nature 7 doesn't have. If you want the absolute maximum from an outdoor sauna, built by doctors, with both infrared and steam in one cedar cabin, the Nature 8 Plus is the only option.

Flagship Outdoor Model 12,000W Total Output Infrared + Steam Hybrid 11 Outdoor Heaters (100X Stronger) 8,000W Steam Stove 4-6 Person Executive SPA Design Natural Cedar 3-Year Warranty

Electrical requirement: 220V/50A hardwired + 120V plug. The Nature 8 Plus requires a 220V/50A hardwired circuit for the heaters and stove (licensed electrician required), plus a standard 120V plug for interior lights. This is a heavy-duty 220V circuit, larger than what the Nature 7 needs (40-50A). Plan for electrician costs of $400-$1,000 depending on distance from your panel and whether your panel can handle the load. Have your electrician verify panel capacity before ordering.

Nature 8 Plus vs the model below: What the Flagship Adds

The Nature 8 Plus includes everything in the the model below plus three exclusive features and more raw power:

Executive SPA Design — A premium layout exclusive to the Nature 8 Plus. The 66.2″ × 63.2″ interior is nearly square, giving all 4-6 occupants equal access to heaters and steam from every seat. The design is built for a spa-grade experience, not just a backyard sauna.

Extra-Rapid Internal Heating System™ — An upgraded heating system that brings the largest cabin in the Nature lineup to operating temperature in the same time as smaller models. At 12,000W total (4,000W infrared + 8,000W stove), this system pushes more heat per minute than any other Nature model.

Extra-Insulated Airflow System™ — Advanced insulation that keeps the larger cabin at consistent temperature with less energy cycling. Combined with 15% thicker cedar panels, this gives the Nature 8 Plus the best heat retention in the entire outdoor lineup.

12,000W total vs 9,400W — The 8,000W stove is 33% more powerful than the the model below's 6,000W stove. The infrared system runs 4,000W vs 3,400W. Combined output is 28% higher.

4-6 person capacity vs 3-4 — The interior is 10 inches deeper (63.2″ vs 53.2″) and 4 inches taller (79″ vs 75″). Room for 6 adults or a group therapy session.

12,000 Watts: The Most Powerful Outdoor Sauna Built

The Nature 8 Plus runs 12,000W of combined thermal output. To put that in perspective: the indoor Medical 7 Plus (the flagship of the indoor lineup) runs 4,100W. The Nature 8 Plus nearly triples that. The 11 infrared heaters deliver 4,000W of full spectrum near, mid, and far infrared. The 8,000W stove produces traditional steam heat strong enough to fill the 66.2″ × 63.2″ cabin with dense humidity in minutes.

You can run infrared only, steam only, or both simultaneously. In hybrid mode, the infrared provides deep-tissue penetration while the steam drives surface-level sweating and humidity-based detoxification. The combination delivers a session that neither mode achieves alone.

Built for Commercial Use

The Nature 8 Plus is the Nature model most commonly installed at commercial properties. Its 4-6 person capacity, Executive SPA Design, hybrid capability, and 12,000W output make it a centerpiece amenity for wellness resorts, boutique hotels, luxury Airbnbs, retreat centers, medspas, and high-end fitness facilities.

An optional Commercial WiFi Heating System upgrade is available. It replaces the standard stove with a Harvia Verta commercial-grade Finnish heater with WiFi control, thermostat, and remote preheat capability. This upgrade is ideal for properties where staff need to prepare the sauna remotely before guests arrive.

Installing the Nature 8 Plus at a commercial property?

RecovAthlete offers wholesale pricing, multi-unit orders, and dedicated B2B support for commercial installations. We can advise on the WiFi heating upgrade, electrical requirements, and surface preparation for your specific property.

Call 866-861-6317 or email info@recovathlete.com for a custom commercial quote.

Who Is the Nature 8 Plus Outdoor Sauna For?

  • Buyers who want the most powerful, most feature-complete outdoor sauna available
  • Families or groups of 4-6 who sauna together outdoors
  • People who want both infrared and traditional steam in one unit
  • Buyers who prefer the Executive SPA Design for a premium aesthetic
  • Commercial buyers: wellness resorts, luxury Airbnbs, retreat centers, medspas
  • Anyone with 220V/50A electrical capacity at the installation site

Don't need 4-6 person capacity? The Nature 7 seats 3-4 with 10 heaters and a 6,000W stove on 220V/40-50A. Want to stay on 120V? The Nature 6 is the largest outdoor model on a single 120V plug (3 people, dry infrared only).

Designed and Built in the USA

Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The Nature 8 Plus goes through the most extensive weatherproofing, steam system testing, and quality checks of any model in the lineup. Every unit ships direct from LA.

Nature 8 Plus Outdoor Sauna: Frequently Asked Questions

What is the Nature 8 Plus sauna?

The Nature 8 Plus is the flagship outdoor sauna from Medical Saunas. It seats 4-6 people, combines 11 full spectrum infrared heaters (4,000W) with an 8,000W steam stove for 12,000W total output, and features an Executive SPA Design exclusive to this model. It is built with natural cedar, requires 220V/50A hardwired electrical, and weighs 1,614 lbs. It is the most powerful outdoor sauna Medical Saunas has ever built.

What is the difference between the Nature 8 Plus and Nature 7?

The Nature 8 Plus adds three exclusive features: Executive SPA Design, Extra-Rapid Internal Heating, and Extra-Insulated Airflow. It seats 4-6 people (vs 3-4), has 11 heaters (vs 10), and an 8,000W stove (vs 6,000W) for 12,000W total (vs 9,400W). The interior is 10 inches deeper and 4 inches taller. Both use cedar and 220V electrical, but the Nature 8 Plus needs a 50A circuit vs 40-50A.

Does the Nature 8 Plus require an electrician?

Yes. The Nature 8 Plus requires a 220V/50A hardwired circuit by a licensed electrician, plus a standard 120V plug for lights. This is a heavy-duty circuit. Have your electrician verify your panel can handle the load before ordering. Typical installation cost: $400-$1,000 depending on distance and panel upgrades needed.

How many people fit in the Nature 8 Plus?

4-6 people seated. The interior is 66.2 x 63.2 inches (over 5.5 x 5.3 feet) with 79 inches of headroom (6.6 feet). Four adults sit very comfortably. Five to six adults fit with slightly less personal space. The Executive SPA Design distributes seating so everyone gets equal heater and steam exposure.

Can the Nature 8 Plus be used for a business?

Yes. The Nature 8 Plus is the most popular Nature model for commercial use. Its 4-6 person capacity, hybrid infrared + steam, Executive SPA Design, and 12,000W output make it a premium amenity for wellness resorts, luxury Airbnbs, retreat centers, and medspas. An optional Commercial WiFi Heating System upgrade adds remote preheat and Harvia Verta commercial-grade stove. Call 866-861-6317 for wholesale pricing.

What is the Executive SPA Design?

Executive SPA Design is a premium layout exclusive to the Nature 8 Plus. The nearly square interior (66.2 x 63.2 inches) distributes seating and heater exposure evenly across all positions. It is designed for a spa-grade aesthetic and experience, making it the preferred choice for commercial installations and high-end home wellness rooms.

How much space do I need for the Nature 8 Plus?

The exterior with overhang is 75.9 x 74.6 inches (about 6.3 x 6.2 feet) and 91.2 inches tall (7.6 feet). You need a level, solid surface like a concrete pad or reinforced deck that can support 1,614 lbs. Allow extra clearance for door swing, airflow, and access to the 220V connection. This is the largest footprint in the Nature Series.

Can the Nature 8 Plus stay outside year-round?

Yes. Built for permanent outdoor placement with extra-thick cedar walls, 15% thicker panels, Extra-Insulated Airflow, roof overhang, and outdoor-rated hardware. Cedar is naturally resistant to rot, decay, and insects. Handles all four seasons including heavy rain, snow, humidity, and extreme temperature swings.

Is there a WiFi upgrade for the Nature 8 Plus?

Yes. The optional Commercial WiFi Heating System upgrade replaces the standard stove with a Harvia Verta commercial-grade Finnish heater. It includes WiFi control for remote preheat, a thermostat, power box, heater guard, and rocks. This upgrade is ideal for commercial properties where staff need to prepare the sauna before guests arrive. Contact us for pricing and availability.

It seats 4-6 people (vs 3-4), has 11 heaters (vs 10), and an 8,000W stove (vs 6,000W) for 12,000W total (vs 9,400W). The interior is 10 inches deeper and 4 inches taller. Both use cedar and 220V electrical, but the Nature 8 Plus needs a 50A circuit vs 40-50A.

Does the Nature 8 Plus require an electrician?

Yes. The Nature 8 Plus requires a 220V/50A hardwired circuit by a licensed electrician, plus a standard 120V plug for lights. This is a heavy-duty circuit. Have your electrician verify your panel can handle the load before ordering. Typical installation cost: $400-$1,000 depending on distance and panel upgrades needed.

How many people fit in the Nature 8 Plus?

4-6 people seated. The interior is 66.2 x 63.2 inches (over 5.5 x 5.3 feet) with 79 inches of headroom (6.6 feet). Four adults sit very comfortably. Five to six adults fit with slightly less personal space. The Executive SPA Design distributes seating so everyone gets equal heater and steam exposure.

Can the Nature 8 Plus be used for a business?

Yes. The Nature 8 Plus is the most popular Nature model for commercial use. Its 4-6 person capacity, hybrid infrared + steam, Executive SPA Design, and 12,000W output make it a premium amenity for wellness resorts, luxury Airbnbs, retreat centers, and medspas. An optional Commercial WiFi Heating System upgrade adds remote preheat and Harvia Verta commercial-grade stove. Call 866-861-6317 for wholesale pricing.

What is the Executive SPA Design?

Executive SPA Design is a premium layout exclusive to the Nature 8 Plus. The nearly square interior (66.2 x 63.2 inches) distributes seating and heater exposure evenly across all positions. It is designed for a spa-grade aesthetic and experience, making it the preferred choice for commercial installations and high-end home wellness rooms.

How much space do I need for the Nature 8 Plus?

The exterior with overhang is 75.9 x 74.6 inches (about 6.3 x 6.2 feet) and 91.2 inches tall (7.6 feet). You need a level, solid surface like a concrete pad or reinforced deck that can support 1,614 lbs. Allow extra clearance for door swing, airflow, and access to the 220V connection. This is the largest footprint in the Nature Series.

Can the Nature 8 Plus stay outside year-round?

Yes. Built for permanent outdoor placement with extra-thick cedar walls, 15% thicker panels, Extra-Insulated Airflow, roof overhang, and outdoor-rated hardware. Cedar is naturally resistant to rot, decay, and insects. Handles all four seasons including heavy rain, snow, humidity, and extreme temperature swings.

Is there a WiFi upgrade for the Nature 8 Plus?

Yes. The optional Commercial WiFi Heating System upgrade replaces the standard stove with a Harvia Verta commercial-grade Finnish heater. It includes WiFi control for remote preheat, a thermostat, power box, heater guard, and rocks. This upgrade is ideal for commercial properties where staff need to prepare the sauna before guests arrive. Contact us for pricing and availability.

Capacity: 4-6 people

Price range: Check current sale price above

Key fact: The most powerful outdoor sauna ever built. Designed by 48 doctors. 11 Ultra Full Spectrum Outdoor Heaters (100X Stronger) at 4,000W plus an 8,000W traditional steam stove (12,000W total). Executive SPA Design with Extra-Rapid Heating and Extra-Insulated Airflow, both exclusive to this model. Natural cedar construction. Requires 220V/50A hardwired electrical. 1,614 lbs. Hand-assembled in Los Angeles, CA.

Nature 8 Plus Outdoor Sauna: 4-6 Person Flagship Hybrid, 12,000W

The Nature 8 Plus is the flagship of the entire Nature Series and the most powerful outdoor sauna Medical Saunas has ever built. It seats 4-6 people in an Executive SPA Design, runs 11 full spectrum infrared heaters at 4,000W alongside an 8,000W traditional steam stove, and includes every feature in the Nature lineup plus three exclusives found only at this tier.

At 12,000W combined output, this sauna delivers more thermal power than many commercial installations. The Executive SPA Design, Extra-Rapid Internal Heating, and Extra-Insulated Airflow are features the Nature 7 doesn't have. If you want the absolute maximum from an outdoor sauna, built by doctors, with both infrared and steam in one cedar cabin, the Nature 8 Plus is the only option.

Flagship Outdoor Model 12,000W Total Output Infrared + Steam Hybrid 11 Outdoor Heaters (100X Stronger) 8,000W Steam Stove 4-6 Person Executive SPA Design Natural Cedar 3-Year Warranty

Electrical requirement: 220V/50A hardwired + 120V plug. The Nature 8 Plus requires a 220V/50A hardwired circuit for the heaters and stove (licensed electrician required), plus a standard 120V plug for interior lights. This is a heavy-duty 220V circuit, larger than what the Nature 7 needs (40-50A). Plan for electrician costs of $400-$1,000 depending on distance from your panel and whether your panel can handle the load. Have your electrician verify panel capacity before ordering.

Nature 8 Plus vs the model below: What the Flagship Adds

The Nature 8 Plus includes everything in the the model below plus three exclusive features and more raw power:

Executive SPA Design — A premium layout exclusive to the Nature 8 Plus. The 66.2″ × 63.2″ interior is nearly square, giving all 4-6 occupants equal access to heaters and steam from every seat. The design is built for a spa-grade experience, not just a backyard sauna.

Extra-Rapid Internal Heating System™ — An upgraded heating system that brings the largest cabin in the Nature lineup to operating temperature in the same time as smaller models. At 12,000W total (4,000W infrared + 8,000W stove), this system pushes more heat per minute than any other Nature model.

Extra-Insulated Airflow System™ — Advanced insulation that keeps the larger cabin at consistent temperature with less energy cycling. Combined with 15% thicker cedar panels, this gives the Nature 8 Plus the best heat retention in the entire outdoor lineup.

12,000W total vs 9,400W — The 8,000W stove is 33% more powerful than the the model below's 6,000W stove. The infrared system runs 4,000W vs 3,400W. Combined output is 28% higher.

4-6 person capacity vs 3-4 — The interior is 10 inches deeper (63.2″ vs 53.2″) and 4 inches taller (79″ vs 75″). Room for 6 adults or a group therapy session.

12,000 Watts: The Most Powerful Outdoor Sauna Built

The Nature 8 Plus runs 12,000W of combined thermal output. To put that in perspective: the indoor Medical 7 Plus (the flagship of the indoor lineup) runs 4,100W. The Nature 8 Plus nearly triples that. The 11 infrared heaters deliver 4,000W of full spectrum near, mid, and far infrared. The 8,000W stove produces traditional steam heat strong enough to fill the 66.2″ × 63.2″ cabin with dense humidity in minutes.

You can run infrared only, steam only, or both simultaneously. In hybrid mode, the infrared provides deep-tissue penetration while the steam drives surface-level sweating and humidity-based detoxification. The combination delivers a session that neither mode achieves alone.

Built for Commercial Use

The Nature 8 Plus is the Nature model most commonly installed at commercial properties. Its 4-6 person capacity, Executive SPA Design, hybrid capability, and 12,000W output make it a centerpiece amenity for wellness resorts, boutique hotels, luxury Airbnbs, retreat centers, medspas, and high-end fitness facilities.

An optional Commercial WiFi Heating System upgrade is available. It replaces the standard stove with a Harvia Verta commercial-grade Finnish heater with WiFi control, thermostat, and remote preheat capability. This upgrade is ideal for properties where staff need to prepare the sauna remotely before guests arrive.

Installing the Nature 8 Plus at a commercial property?

RecovAthlete offers wholesale pricing, multi-unit orders, and dedicated B2B support for commercial installations. We can advise on the WiFi heating upgrade, electrical requirements, and surface preparation for your specific property.

Call 866-861-6317 or email info@recovathlete.com for a custom commercial quote.

Who Is the Nature 8 Plus Outdoor Sauna For?

  • Buyers who want the most powerful, most feature-complete outdoor sauna available
  • Families or groups of 4-6 who sauna together outdoors
  • People who want both infrared and traditional steam in one unit
  • Buyers who prefer the Executive SPA Design for a premium aesthetic
  • Commercial buyers: wellness resorts, luxury Airbnbs, retreat centers, medspas
  • Anyone with 220V/50A electrical capacity at the installation site

Don't need 4-6 person capacity? The Nature 7 seats 3-4 with 10 heaters and a 6,000W stove on 220V/40-50A. Want to stay on 120V? The Nature 6 is the largest outdoor model on a single 120V plug (3 people, dry infrared only).

Designed and Built in the USA

Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The Nature 8 Plus goes through the most extensive weatherproofing, steam system testing, and quality checks of any model in the lineup. Every unit ships direct from LA.

Nature 8 Plus Outdoor Sauna: 4-6 Person Flagship Hybrid, 12,000W

The Nature 8 Plus is the flagship of the entire Nature Series and the most powerful outdoor sauna Medical Saunas has ever built. It seats 4-6 people in an Executive SPA Design, runs 11 full spectrum infrared heaters at 4,000W alongside an 8,000W traditional steam stove, and includes every feature in the Nature lineup plus three exclusives found only at this tier.

At 12,000W combined output, this sauna delivers more thermal power than many commercial installations. The Executive SPA Design, Extra-Rapid Internal Heating, and Extra-Insulated Airflow are features the Nature 7 doesn't have. If you want the absolute maximum from an outdoor sauna, built by doctors, with both infrared and steam in one cedar cabin, the Nature 8 Plus is the only option.

Flagship Outdoor Model 12,000W Total Output Infrared + Steam Hybrid 11 Outdoor Heaters (100X Stronger) 8,000W Steam Stove 4-6 Person Executive SPA Design Natural Cedar 3-Year Warranty

Electrical requirement: 220V/50A hardwired + 120V plug. The Nature 8 Plus requires a 220V/50A hardwired circuit for the heaters and stove (licensed electrician required), plus a standard 120V plug for interior lights. This is a heavy-duty 220V circuit, larger than what the Nature 7 needs (40-50A). Plan for electrician costs of $400-$1,000 depending on distance from your panel and whether your panel can handle the load. Have your electrician verify panel capacity before ordering.

Nature 8 Plus vs the model below: What the Flagship Adds

The Nature 8 Plus includes everything in the the model below plus three exclusive features and more raw power:

Executive SPA Design — A premium layout exclusive to the Nature 8 Plus. The 66.2″ × 63.2″ interior is nearly square, giving all 4-6 occupants equal access to heaters and steam from every seat. The design is built for a spa-grade experience, not just a backyard sauna.

Extra-Rapid Internal Heating System™ — An upgraded heating system that brings the largest cabin in the Nature lineup to operating temperature in the same time as smaller models. At 12,000W total (4,000W infrared + 8,000W stove), this system pushes more heat per minute than any other Nature model.

Extra-Insulated Airflow System™ — Advanced insulation that keeps the larger cabin at consistent temperature with less energy cycling. Combined with 15% thicker cedar panels, this gives the Nature 8 Plus the best heat retention in the entire outdoor lineup.

12,000W total vs 9,400W — The 8,000W stove is 33% more powerful than the the model below's 6,000W stove. The infrared system runs 4,000W vs 3,400W. Combined output is 28% higher.

4-6 person capacity vs 3-4 — The interior is 10 inches deeper (63.2″ vs 53.2″) and 4 inches taller (79″ vs 75″). Room for 6 adults or a group therapy session.

12,000 Watts: The Most Powerful Outdoor Sauna Built

The Nature 8 Plus runs 12,000W of combined thermal output. To put that in perspective: the indoor Medical 7 Plus (the flagship of the indoor lineup) runs 4,100W. The Nature 8 Plus nearly triples that. The 11 infrared heaters deliver 4,000W of full spectrum near, mid, and far infrared. The 8,000W stove produces traditional steam heat strong enough to fill the 66.2″ × 63.2″ cabin with dense humidity in minutes.

You can run infrared only, steam only, or both simultaneously. In hybrid mode, the infrared provides deep-tissue penetration while the steam drives surface-level sweating and humidity-based detoxification. The combination delivers a session that neither mode achieves alone.

Built for Commercial Use

The Nature 8 Plus is the Nature model most commonly installed at commercial properties. Its 4-6 person capacity, Executive SPA Design, hybrid capability, and 12,000W output make it a centerpiece amenity for wellness resorts, boutique hotels, luxury Airbnbs, retreat centers, medspas, and high-end fitness facilities.

An optional Commercial WiFi Heating System upgrade is available. It replaces the standard stove with a Harvia Verta commercial-grade Finnish heater with WiFi control, thermostat, and remote preheat capability. This upgrade is ideal for properties where staff need to prepare the sauna remotely before guests arrive.

Who Is the Nature 8 Plus Outdoor Sauna For?

  • Buyers who want the most powerful, most feature-complete outdoor sauna available
  • Families or groups of 4-6 who sauna together outdoors
  • People who want both infrared and traditional steam in one unit
  • Buyers who prefer the Executive SPA Design for a premium aesthetic
  • Commercial buyers: wellness resorts, luxury Airbnbs, retreat centers, medspas
  • Anyone with 220V/50A electrical capacity at the installation site

Don't need 4-6 person capacity? The Nature 7 seats 3-4 with 10 heaters and a 6,000W stove on 220V/40-50A. Want to stay on 120V? The Nature 6 is the largest outdoor model on a single 120V plug (3 people, dry infrared only).

Designed and Built in the USA

Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The Nature 8 Plus goes through the most extensive weatherproofing, steam system testing, and quality checks of any model in the lineup. Every unit ships direct from LA.

Nature 8 Plus Outdoor Sauna: Frequently Asked Questions

What is the Nature 8 Plus sauna?

The Nature 8 Plus is the flagship outdoor sauna from Medical Saunas. It seats 4-6 people, combines 11 full spectrum infrared heaters (4,000W) with an 8,000W steam stove for 12,000W total output, and features an Executive SPA Design exclusive to this model. It is built with natural cedar, requires 220V/50A hardwired electrical, and weighs 1,614 lbs. It is the most powerful outdoor sauna Medical Saunas has ever built.

What is the difference between the Nature 8 Plus and Nature 7?

The Nature 8 Plus adds three exclusive features: Executive SPA Design, Extra-Rapid Internal Heating, and Extra-Insulated Airflow. It seats 4-6 people (vs 3-4), has 11 heaters (vs 10), and an 8,000W stove (vs 6,000W) for 12,000W total (vs 9,400W). The interior is 10 inches deeper and 4 inches taller. Both use cedar and 220V electrical, but the Nature 8 Plus needs a 50A circuit vs 40-50A.

Does the Nature 8 Plus require an electrician?

Yes. The Nature 8 Plus requires a 220V/50A hardwired circuit by a licensed electrician, plus a standard 120V plug for lights. This is a heavy-duty circuit. Have your electrician verify your panel can handle the load before ordering. Typical installation cost: $400-$1,000 depending on distance and panel upgrades needed.

How many people fit in the Nature 8 Plus?

4-6 people seated. The interior is 66.2 x 63.2 inches (over 5.5 x 5.3 feet) with 79 inches of headroom (6.6 feet). Four adults sit very comfortably. Five to six adults fit with slightly less personal space. The Executive SPA Design distributes seating so everyone gets equal heater and steam exposure.

Can the Nature 8 Plus be used for a business?

Yes. The Nature 8 Plus is the most popular Nature model for commercial use. Its 4-6 person capacity, hybrid infrared + steam, Executive SPA Design, and 12,000W output make it a premium amenity for wellness resorts, luxury Airbnbs, retreat centers, and medspas. An optional Commercial WiFi Heating System upgrade adds remote preheat and Harvia Verta commercial-grade stove. Call 866-861-6317 for wholesale pricing.

What is the Executive SPA Design?

Executive SPA Design is a premium layout exclusive to the Nature 8 Plus. The nearly square interior (66.2 x 63.2 inches) distributes seating and heater exposure evenly across all positions. It is designed for a spa-grade aesthetic and experience, making it the preferred choice for commercial installations and high-end home wellness rooms.

How much space do I need for the Nature 8 Plus?

The exterior with overhang is 75.9 x 74.6 inches (about 6.3 x 6.2 feet) and 91.2 inches tall (7.6 feet). You need a level, solid surface like a concrete pad or reinforced deck that can support 1,614 lbs. Allow extra clearance for door swing, airflow, and access to the 220V connection. This is the largest footprint in the Nature Series.

Can the Nature 8 Plus stay outside year-round?

Yes. Built for permanent outdoor placement with extra-thick cedar walls, 15% thicker panels, Extra-Insulated Airflow, roof overhang, and outdoor-rated hardware. Cedar is naturally resistant to rot, decay, and insects. Handles all four seasons including heavy rain, snow, humidity, and extreme temperature swings.

Is there a WiFi upgrade for the Nature 8 Plus?

Yes. The optional Commercial WiFi Heating System upgrade replaces the standard stove with a Harvia Verta commercial-grade Finnish heater. It includes WiFi control for remote preheat, a thermostat, power box, heater guard, and rocks. This upgrade is ideal for commercial properties where staff need to prepare the sauna before guests arrive. Contact us for pricing and availability.

Nature 8 Plus vs the model below: What the Flagship Adds

The Nature 8 Plus includes everything in the the model below plus three exclusive features and more raw power:

Executive SPA Design — A premium layout exclusive to the Nature 8 Plus. The 66.2″ × 63.2″ interior is nearly square, giving all 4-6 occupants equal access to heaters and steam from every seat. The design is built for a spa-grade experience, not just a backyard sauna.

Extra-Rapid Internal Heating System™ — An upgraded heating system that brings the largest cabin in the Nature lineup to operating temperature in the same time as smaller models. At 12,000W total (4,000W infrared + 8,000W stove), this system pushes more heat per minute than any other Nature model.

Extra-Insulated Airflow System™ — Advanced insulation that keeps the larger cabin at consistent temperature with less energy cycling. Combined with 15% thicker cedar panels, this gives the Nature 8 Plus the best heat retention in the entire outdoor lineup.

12,000W total vs 9,400W — The 8,000W stove is 33% more powerful than the the model below's 6,000W stove. The infrared system runs 4,000W vs 3,400W. Combined output is 28% higher.

4-6 person capacity vs 3-4 — The interior is 10 inches deeper (63.2″ vs 53.2″) and 4 inches taller (79″ vs 75″). Room for 6 adults or a group therapy session.

12,000 Watts: The Most Powerful Outdoor Sauna Built

The Nature 8 Plus runs 12,000W of combined thermal output. To put that in perspective: the indoor Medical 7 Plus (the flagship of the indoor lineup) runs 4,100W. The Nature 8 Plus nearly triples that. The 11 infrared heaters deliver 4,000W of full spectrum near, mid, and far infrared. The 8,000W stove produces traditional steam heat strong enough to fill the 66.2″ × 63.2″ cabin with dense humidity in minutes.

You can run infrared only, steam only, or both simultaneously. In hybrid mode, the infrared provides deep-tissue penetration while the steam drives surface-level sweating and humidity-based detoxification. The combination delivers a session that neither mode achieves alone.

Built for Commercial Use

The Nature 8 Plus is the Nature model most commonly installed at commercial properties. Its 4-6 person capacity, Executive SPA Design, hybrid capability, and 12,000W output make it a centerpiece amenity for wellness resorts, boutique hotels, luxury Airbnbs, retreat centers, medspas, and high-end fitness facilities.

An optional Commercial WiFi Heating System upgrade is available. It replaces the standard stove with a Harvia Verta commercial-grade Finnish heater with WiFi control, thermostat, and remote preheat capability. This upgrade is ideal for properties where staff need to prepare the sauna remotely before guests arrive.

Installing the Nature 8 Plus at a commercial property?

RecovAthlete offers wholesale pricing, multi-unit orders, and dedicated B2B support for commercial installations. We can advise on the WiFi heating upgrade, electrical requirements, and surface preparation for your specific property.

Call 866-861-6317 or email info@recovathlete.com for a custom commercial quote.

Who Is the Nature 8 Plus Outdoor Sauna For?

  • Buyers who want the most powerful, most feature-complete outdoor sauna available
  • Families or groups of 4-6 who sauna together outdoors
  • People who want both infrared and traditional steam in one unit
  • Buyers who prefer the Executive SPA Design for a premium aesthetic
  • Commercial buyers: wellness resorts, luxury Airbnbs, retreat centers, medspas
  • Anyone with 220V/50A electrical capacity at the installation site

Don't need 4-6 person capacity? The Nature 7 seats 3-4 with 10 heaters and a 6,000W stove on 220V/40-50A. Want to stay on 120V? The Nature 6 is the largest outdoor model on a single 120V plug (3 people, dry infrared only).

Designed and Built in the USA

Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The Nature 8 Plus goes through the most extensive weatherproofing, steam system testing, and quality checks of any model in the lineup. Every unit ships direct from LA.

It seats 4-6 people (vs 3-4), has 11 heaters (vs 10), and an 8,000W stove (vs 6,000W) for 12,000W total (vs 9,400W). The interior is 10 inches deeper and 4 inches taller. Both use cedar and 220V electrical, but the Nature 8 Plus needs a 50A circuit vs 40-50A.

Does the Nature 8 Plus require an electrician?

Yes. The Nature 8 Plus requires a 220V/50A hardwired circuit by a licensed electrician, plus a standard 120V plug for lights. This is a heavy-duty circuit. Have your electrician verify your panel can handle the load before ordering. Typical installation cost: $400-$1,000 depending on distance and panel upgrades needed.

How many people fit in the Nature 8 Plus?

4-6 people seated. The interior is 66.2 x 63.2 inches (over 5.5 x 5.3 feet) with 79 inches of headroom (6.6 feet). Four adults sit very comfortably. Five to six adults fit with slightly less personal space. The Executive SPA Design distributes seating so everyone gets equal heater and steam exposure.

Can the Nature 8 Plus be used for a business?

Yes. The Nature 8 Plus is the most popular Nature model for commercial use. Its 4-6 person capacity, hybrid infrared + steam, Executive SPA Design, and 12,000W output make it a premium amenity for wellness resorts, luxury Airbnbs, retreat centers, and medspas. An optional Commercial WiFi Heating System upgrade adds remote preheat and Harvia Verta commercial-grade stove. Call 866-861-6317 for wholesale pricing.

What is the Executive SPA Design?

Executive SPA Design is a premium layout exclusive to the Nature 8 Plus. The nearly square interior (66.2 x 63.2 inches) distributes seating and heater exposure evenly across all positions. It is designed for a spa-grade aesthetic and experience, making it the preferred choice for commercial installations and high-end home wellness rooms.

How much space do I need for the Nature 8 Plus?

The exterior with overhang is 75.9 x 74.6 inches (about 6.3 x 6.2 feet) and 91.2 inches tall (7.6 feet). You need a level, solid surface like a concrete pad or reinforced deck that can support 1,614 lbs. Allow extra clearance for door swing, airflow, and access to the 220V connection. This is the largest footprint in the Nature Series.

Can the Nature 8 Plus stay outside year-round?

Yes. Built for permanent outdoor placement with extra-thick cedar walls, 15% thicker panels, Extra-Insulated Airflow, roof overhang, and outdoor-rated hardware. Cedar is naturally resistant to rot, decay, and insects. Handles all four seasons including heavy rain, snow, humidity, and extreme temperature swings.

Is there a WiFi upgrade for the Nature 8 Plus?

Yes. The optional Commercial WiFi Heating System upgrade replaces the standard stove with a Harvia Verta commercial-grade Finnish heater. It includes WiFi control for remote preheat, a thermostat, power box, heater guard, and rocks. This upgrade is ideal for commercial properties where staff need to prepare the sauna before guests arrive. Contact us for pricing and availability.

WARRANTY AT A GLANCE
  • Duration: 3 years from date of receipt
  • Coverage: Defects in materials and workmanship under residential use
  • Parts: Covered under warranty
  • Service / labor costs: Not included in the 3-year warranty
  • Misuse or negligence: Not covered
  • Who to contact: RecovAthlete — 866-861-6317

What the Warranty Covers

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.

What Is Not Covered

NOT COVERED:
  • Damage caused by misuse or negligence
  • Damage from commercial or non-residential use
  • Normal wear over time
  • Damage caused during customer-arranged delivery or setup
  • Service and labor costs — these are billed separately regardless of warranty status

Who This Warranty Applies To

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.

How to Make a Warranty Claim

If your Medical Breakthrough massage chair develops a defect covered under warranty, follow these steps:

  1. Call RecovAthlete at 866-861-6317 to report the issue
  2. Our team will gather details and diagnose the problem — many issues are resolvable without a parts replacement
  3. If a covered part needs replacing, we will coordinate the claim and delivery of the replacement part
  4. If a technician visit is required, we will advise on the service cost before any work is arranged
IMPORTANT: SERVICE COSTS

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.
