Product: Nature 5 Outdoor Infrared Sauna by Medical Saunas™
Type: Outdoor full spectrum infrared sauna with removable bench for hot yoga
Capacity: 2 people
Price range: Check current sale price above
Key fact: Designed by 48 doctors over 10 years. 7 Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard heaters. Built for outdoor use with extra-thick weather-resistant walls. Removable bench converts the cabin into a hot yoga space. Natural Canadian hemlock construction. Runs on a single 120V/40A plug. Hand-assembled in Los Angeles, CA.
The Nature 5 is a 2-person outdoor infrared sauna built for backyards, patios, and decks. It features 7 Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard heaters, extra-thick weather-resistant walls, and a removable bench that converts the sauna into a hot yoga studio. It was engineered by 48 doctors, pain specialists, and cardiologists over a decade of research.
This is the first outdoor model in the Nature Series with enough interior space for two people to sit side by side, or for one person to remove the bench and lay down a yoga mat. The hot yoga movement is the core design driver here. Expanded dimensions, removable seating, and full spectrum heat combine to give you the benefits of a hot yoga class in your own backyard.
Electrical note: The Nature 5 requires a single 120V/40A dedicated circuit. This is higher than a standard 15A or 20A household outlet. You will likely need an electrician to install a 40A breaker and run a dedicated line to your outdoor location. Typical cost: $200-$600 depending on distance from your panel. This is a single-plug setup (not two plugs like the indoor Medical 5/6).

The Nature 5 is purpose-built for hot yoga at home. Remove the bench, lay down a yoga mat, and you have a heated space large enough for standing poses like Half Moon, Eagle, and Standing Bow. The full spectrum infrared heat loosens muscles and joints, improves range of motion, and increases circulation while you stretch.
Standard saunas are too small for yoga and don't have removable seating. The Nature 5 solves both problems. The interior is 46″ wide and 41″ deep with 75″ of headroom. With the bench out, that's enough floor space for a compact yoga mat and room to move through poses.
Hot yoga in a Medical Sauna can be used as a morning warm-up to start your day or an evening cooldown after work. A few sessions per week and you'll notice improved flexibility, better posture, and deeper relaxation.
Both are outdoor hemlock saunas with the same core therapy systems. The Nature 5 adds capacity and an extra heater:
2-person capacity vs 1-person — The Nature 5's interior is 46″ × 41″ vs the Nature 4's 36″ × 36″. Room for two adults seated, or one person with the bench removed for yoga.
7 heaters vs 6 — One additional heater covers the wider cabin. Both use the same 100X Stronger Outdoor Heaters.
2,600W vs 2,200W — More power for the larger space. Same fast heat-up time.
Same 120V single-plug setup — Both use one 120V plug. The Nature 5 needs a 40A circuit vs the Nature 4's 25-30A.
The Nature Series uses Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard indoor heaters. Outdoor saunas face wind, cold ambient temperatures, and heat loss through the door. These heaters compensate for all of that, maintaining consistent cabin temperature even in cooler weather. The full spectrum output covers near, mid, and far infrared wavelengths for the broadest therapeutic range per session.
Built to handle rain, humidity, UV exposure, and temperature swings. The extra-thick hemlock panels provide insulation far beyond what indoor models need. The roof overhang extends beyond the cabin walls to protect the entry area from rain and direct sun. The tempered glass door and all hardware are rated for outdoor conditions.
Every heater panel has a protective cover made from the same hemlock wood as the cabin. This prevents accidental contact with hot surfaces during yoga poses or when multiple users are seated. A safety feature most outdoor sauna brands skip.
The bench lifts out without tools. With the bench in, two people sit comfortably with backrests for lumbar support. With the bench out, you have open floor space for a yoga mat, stretching, or standing therapy. The backrests are included at no extra cost.
Hemlock was selected for its outdoor durability and health properties. It hardens with age, resists moisture better than many softwoods, and has natural astringent properties that enhance skin cleansing during sessions. The wood releases a clean, natural aroma when heated.
Reaches operating temperature in about 40 minutes despite being outdoors. The 7 heaters at 2,600W combined with extra-thick insulation keep the cabin hot even when ambient temperatures are cooler. Most outdoor saunas take well over an hour to heat up.
Need a smaller outdoor unit? The Nature 4 fits 1 person with 6 heaters. Need more room? The Nature 6 fits 3 people with 9 heaters. Want a hybrid dry/steam outdoor sauna? The Nature 7 and Nature 8 Plus add a steam stove alongside the infrared heaters.
Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The Nature Series outdoor saunas go through additional weatherproofing and quality checks before shipping. Every unit ships direct from LA.
Medical Saunas™ only lists health benefits found in published clinical studies. The Nature Series applies the same research-driven approach used in the indoor Medical Sauna Series, adapted for outdoor use with stronger heaters and weather-resistant construction. Each therapy system was selected for its measured health impact.

Yes. The Nature 5 is built for permanent outdoor placement. It has extra-thick weather-resistant hemlock walls, a roof overhang for rain and sun protection, outdoor-rated hardware, and 100X Stronger heaters designed to maintain temperature even in cooler weather. It handles rain, humidity, UV exposure, and temperature swings.
Most likely yes. The Nature 5 requires a 120V/40A dedicated circuit, which is higher than a standard household outlet (15A or 20A).

A hot yoga sauna is an infrared sauna designed with expanded interior dimensions and removable benches so you can practice yoga poses inside the heated cabin. The Nature Series by Medical Saunas is the industry's first hot yoga sauna line. The infrared heat loosens muscles and joints, improves flexibility and circulation, and provides all the detox benefits of a regular sauna session while you do yoga.
The Nature 6 fits 3 people (vs 2), has 9 heaters (vs 7), runs at 3,400W (vs 2,600W), and has a wider interior at 56 x 41 inches (vs 46 x 41). Both use the same 120V/40A single-plug electrical setup, hemlock construction, and outdoor-rated design. Choose the Nature 5 for 2-person or solo yoga use. Choose the Nature 6 if you need room for 3 or want more heater coverage.
Nature Saunas are built for outdoor use with extra-thick weather-resistant walls, roof overhangs, protective heater covers, and 100X Stronger outdoor heaters. They also feature removable benches for hot yoga, which indoor models don't have. Indoor Medical Saunas have a wider feature range (silent heating, audio theater, etc.) but are not weather-rated. If you plan to place the sauna on a patio, deck, or backyard, choose a Nature model. If it's going in a room, garage, or basement, choose an indoor Medical model.
The Nature 5 is a dry infrared sauna only. It uses 7 full spectrum infrared heaters and does not include a steam stove. If you want a hybrid sauna that does both dry infrared and traditional steam, look at the Nature 7 or Nature 8 Plus. Those models include both infrared heaters and a steam stove, but they require 220V hardwired electrical and use cedar instead of hemlock.
The Nature 5 already uses Ultra Full Spectrum heaters that include red light wavelengths as part of the near-infrared spectrum. This provides some of the skin and surface tissue benefits associated with red light therapy during every session. For dedicated red light therapy equipment, browse our red light therapy collection.
947 lbs fully assembled. You'll need 2-3 people for assembly and a solid, level surface like a concrete pad, reinforced deck, or paver patio. The exterior footprint with overhang is 50 x 45 inches (about 4.2 x 3.75 feet). Make sure your surface can support the weight.

The Nature 5 is a 2-person outdoor infrared sauna built for backyards, patios, and decks. It features 7 Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard heaters, extra-thick weather-resistant walls, and a removable bench that converts the sauna into a hot yoga studio. It was engineered by 48 doctors, pain specialists, and cardiologists over a decade of research.
This is the first outdoor model in the Nature Series with enough interior space for two people to sit side by side, or for one person to remove the bench and lay down a yoga mat. The hot yoga movement is the core design driver here. Expanded dimensions, removable seating, and full spectrum heat combine to give you the benefits of a hot yoga class in your own backyard.
Electrical note: The Nature 5 requires a single 120V/40A dedicated circuit. This is higher than a standard 15A or 20A household outlet. You will likely need an electrician to install a 40A breaker and run a dedicated line to your outdoor location. Typical cost: $200-$600 depending on distance from your panel. This is a single-plug setup (not two plugs like the indoor Medical 5/6).

The Nature 5 is purpose-built for hot yoga at home. Remove the bench, lay down a yoga mat, and you have a heated space large enough for standing poses like Half Moon, Eagle, and Standing Bow. The full spectrum infrared heat loosens muscles and joints, improves range of motion, and increases circulation while you stretch.
Standard saunas are too small for yoga and don't have removable seating. The Nature 5 solves both problems. The interior is 46″ wide and 41″ deep with 75″ of headroom. With the bench out, that's enough floor space for a compact yoga mat and room to move through poses.
Hot yoga in a Medical Sauna can be used as a morning warm-up to start your day or an evening cooldown after work. A few sessions per week and you'll notice improved flexibility, better posture, and deeper relaxation.
Both are outdoor hemlock saunas with the same core therapy systems. The Nature 5 adds capacity and an extra heater:
2-person capacity vs 1-person — The Nature 5's interior is 46″ × 41″ vs the Nature 4's 36″ × 36″. Room for two adults seated, or one person with the bench removed for yoga.
7 heaters vs 6 — One additional heater covers the wider cabin. Both use the same 100X Stronger Outdoor Heaters.
2,600W vs 2,200W — More power for the larger space. Same fast heat-up time.
Same 120V single-plug setup — Both use one 120V plug. The Nature 5 needs a 40A circuit vs the Nature 4's 25-30A.
The Nature Series uses Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard indoor heaters. Outdoor saunas face wind, cold ambient temperatures, and heat loss through the door. These heaters compensate for all of that, maintaining consistent cabin temperature even in cooler weather. The full spectrum output covers near, mid, and far infrared wavelengths for the broadest therapeutic range per session.
Built to handle rain, humidity, UV exposure, and temperature swings. The extra-thick hemlock panels provide insulation far beyond what indoor models need. The roof overhang extends beyond the cabin walls to protect the entry area from rain and direct sun. The tempered glass door and all hardware are rated for outdoor conditions.
Every heater panel has a protective cover made from the same hemlock wood as the cabin. This prevents accidental contact with hot surfaces during yoga poses or when multiple users are seated. A safety feature most outdoor sauna brands skip.
The bench lifts out without tools. With the bench in, two people sit comfortably with backrests for lumbar support. With the bench out, you have open floor space for a yoga mat, stretching, or standing therapy. The backrests are included at no extra cost.
Hemlock was selected for its outdoor durability and health properties. It hardens with age, resists moisture better than many softwoods, and has natural astringent properties that enhance skin cleansing during sessions. The wood releases a clean, natural aroma when heated.
Reaches operating temperature in about 40 minutes despite being outdoors. The 7 heaters at 2,600W combined with extra-thick insulation keep the cabin hot even when ambient temperatures are cooler. Most outdoor saunas take well over an hour to heat up.
Need a smaller outdoor unit? The Nature 4 fits 1 person with 6 heaters. Need more room? The Nature 6 fits 3 people with 9 heaters. Want a hybrid dry/steam outdoor sauna? The Nature 7 and Nature 8 Plus add a steam stove alongside the infrared heaters.
Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The Nature Series outdoor saunas go through additional weatherproofing and quality checks before shipping. Every unit ships direct from LA.
Medical Saunas™ only lists health benefits found in published clinical studies. The Nature Series applies the same research-driven approach used in the indoor Medical Sauna Series, adapted for outdoor use with stronger heaters and weather-resistant construction. Each therapy system was selected for its measured health impact.

Yes. With the removable bench taken out, the interior is 46 inches wide and 41 inches deep with 75 inches of headroom. That's enough floor space for a compact yoga mat and room for standing poses like Half Moon, Eagle, and Standing Bow. The Nature 5 was specifically designed as a hot yoga sauna.

A hot yoga sauna is an infrared sauna designed with expanded interior dimensions and removable benches so you can practice yoga poses inside the heated cabin. The Nature Series by Medical Saunas is the industry's first hot yoga sauna line. The infrared heat loosens muscles and joints, improves flexibility and circulation, and provides all the detox benefits of a regular sauna session while you do yoga.
The Nature 6 fits 3 people (vs 2), has 9 heaters (vs 7), runs at 3,400W (vs 2,600W), and has a wider interior at 56 x 41 inches (vs 46 x 41). Both use the same 120V/40A single-plug electrical setup, hemlock construction, and outdoor-rated design. Choose the Nature 5 for 2-person or solo yoga use. Choose the Nature 6 if you need room for 3 or want more heater coverage.
Nature Saunas are built for outdoor use with extra-thick weather-resistant walls, roof overhangs, protective heater covers, and 100X Stronger outdoor heaters. They also feature removable benches for hot yoga, which indoor models don't have. Indoor Medical Saunas have a wider feature range (silent heating, audio theater, etc.) but are not weather-rated. If you plan to place the sauna on a patio, deck, or backyard, choose a Nature model. If it's going in a room, garage, or basement, choose an indoor Medical model.
The Nature 5 is a dry infrared sauna only. It uses 7 full spectrum infrared heaters and does not include a steam stove. If you want a hybrid sauna that does both dry infrared and traditional steam, look at the Nature 7 or Nature 8 Plus. Those models include both infrared heaters and a steam stove, but they require 220V hardwired electrical and use cedar instead of hemlock.
The Nature 5 already uses Ultra Full Spectrum heaters that include red light wavelengths as part of the near-infrared spectrum. This provides some of the skin and surface tissue benefits associated with red light therapy during every session. For dedicated red light therapy equipment, browse our red light therapy collection.
947 lbs fully assembled. You'll need 2-3 people for assembly and a solid, level surface like a concrete pad, reinforced deck, or paver patio. The exterior footprint with overhang is 50 x 45 inches (about 4.2 x 3.75 feet). Make sure your surface can support the weight.

Product: Nature 5 Outdoor Infrared Sauna by Medical Saunas™
Type: Outdoor full spectrum infrared sauna with removable bench for hot yoga
Capacity: 2 people
Price range: Check current sale price above
Key fact: Designed by 48 doctors over 10 years. 7 Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard heaters. Built for outdoor use with extra-thick weather-resistant walls. Removable bench converts the cabin into a hot yoga space. Natural Canadian hemlock construction. Runs on a single 120V/40A plug. Hand-assembled in Los Angeles, CA.
The Nature 5 is a 2-person outdoor infrared sauna built for backyards, patios, and decks. It features 7 Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard heaters, extra-thick weather-resistant walls, and a removable bench that converts the sauna into a hot yoga studio. It was engineered by 48 doctors, pain specialists, and cardiologists over a decade of research.
This is the first outdoor model in the Nature Series with enough interior space for two people to sit side by side, or for one person to remove the bench and lay down a yoga mat. The hot yoga movement is the core design driver here. Expanded dimensions, removable seating, and full spectrum heat combine to give you the benefits of a hot yoga class in your own backyard.
Electrical note: The Nature 5 requires a single 120V/40A dedicated circuit. This is higher than a standard 15A or 20A household outlet. You will likely need an electrician to install a 40A breaker and run a dedicated line to your outdoor location. Typical cost: $200-$600 depending on distance from your panel. This is a single-plug setup (not two plugs like the indoor Medical 5/6).

The Nature 5 is purpose-built for hot yoga at home. Remove the bench, lay down a yoga mat, and you have a heated space large enough for standing poses like Half Moon, Eagle, and Standing Bow. The full spectrum infrared heat loosens muscles and joints, improves range of motion, and increases circulation while you stretch.
Standard saunas are too small for yoga and don't have removable seating. The Nature 5 solves both problems. The interior is 46″ wide and 41″ deep with 75″ of headroom. With the bench out, that's enough floor space for a compact yoga mat and room to move through poses.
Hot yoga in a Medical Sauna can be used as a morning warm-up to start your day or an evening cooldown after work. A few sessions per week and you'll notice improved flexibility, better posture, and deeper relaxation.
Both are outdoor hemlock saunas with the same core therapy systems. The Nature 5 adds capacity and an extra heater:
2-person capacity vs 1-person — The Nature 5's interior is 46″ × 41″ vs the Nature 4's 36″ × 36″. Room for two adults seated, or one person with the bench removed for yoga.
7 heaters vs 6 — One additional heater covers the wider cabin. Both use the same 100X Stronger Outdoor Heaters.
2,600W vs 2,200W — More power for the larger space. Same fast heat-up time.
Same 120V single-plug setup — Both use one 120V plug. The Nature 5 needs a 40A circuit vs the Nature 4's 25-30A.
The Nature Series uses Ultra Full Spectrum Outdoor Heaters rated 100X stronger than standard indoor heaters. Outdoor saunas face wind, cold ambient temperatures, and heat loss through the door. These heaters compensate for all of that, maintaining consistent cabin temperature even in cooler weather. The full spectrum output covers near, mid, and far infrared wavelengths for the broadest therapeutic range per session.
Built to handle rain, humidity, UV exposure, and temperature swings. The extra-thick hemlock panels provide insulation far beyond what indoor models need. The roof overhang extends beyond the cabin walls to protect the entry area from rain and direct sun. The tempered glass door and all hardware are rated for outdoor conditions.
Every heater panel has a protective cover made from the same hemlock wood as the cabin. This prevents accidental contact with hot surfaces during yoga poses or when multiple users are seated. A safety feature most outdoor sauna brands skip.
The bench lifts out without tools. With the bench in, two people sit comfortably with backrests for lumbar support. With the bench out, you have open floor space for a yoga mat, stretching, or standing therapy. The backrests are included at no extra cost.
Hemlock was selected for its outdoor durability and health properties. It hardens with age, resists moisture better than many softwoods, and has natural astringent properties that enhance skin cleansing during sessions. The wood releases a clean, natural aroma when heated.
Reaches operating temperature in about 40 minutes despite being outdoors. The 7 heaters at 2,600W combined with extra-thick insulation keep the cabin hot even when ambient temperatures are cooler. Most outdoor saunas take well over an hour to heat up.
Need a smaller outdoor unit? The Nature 4 fits 1 person with 6 heaters. Need more room? The Nature 6 fits 3 people with 9 heaters. Want a hybrid dry/steam outdoor sauna? The Nature 7 and Nature 8 Plus add a steam stove alongside the infrared heaters.
Medical Saunas™ are designed, developed, and hand-assembled at the company's Los Angeles factory. The Nature Series outdoor saunas go through additional weatherproofing and quality checks before shipping. Every unit ships direct from LA.
Medical Saunas™ only lists health benefits found in published clinical studies. The Nature Series applies the same research-driven approach used in the indoor Medical Sauna Series, adapted for outdoor use with stronger heaters and weather-resistant construction. Each therapy system was selected for its measured health impact.

Yes. With the removable bench taken out, the interior is 46 inches wide and 41 inches deep with 75 inches of headroom. That's enough floor space for a compact yoga mat and room for standing poses like Half Moon, Eagle, and Standing Bow. The Nature 5 was specifically designed as a hot yoga sauna.
Yes. The bench lifts out without tools. With the bench in, two people sit side-by-side with included backrests. With the bench removed, you have open floor space for yoga, stretching, or standing therapy. Backrests are included at no extra cost.
Yes. The Nature 5 is built for permanent outdoor placement. It has extra-thick weather-resistant hemlock walls, a roof overhang for rain and sun protection, outdoor-rated hardware, and 100X Stronger heaters designed to maintain temperature even in cooler weather. It handles rain, humidity, UV exposure, and temperature swings.
Most likely yes. The Nature 5 requires a 120V/40A dedicated circuit, which is higher than a standard household outlet (15A or 20A). You'll need an electrician to install a 40A breaker and run a dedicated line to your outdoor location. Typical cost is $200-$600 depending on distance from your electrical panel. It uses a single 120V plug (not 220V).
A hot yoga sauna is an infrared sauna designed with expanded interior dimensions and removable benches so you can practice yoga poses inside the heated cabin. The Nature Series by Medical Saunas is the industry's first hot yoga sauna line. The infrared heat loosens muscles and joints, improves flexibility and circulation, and provides all the detox benefits of a regular sauna session while you do yoga.
The Nature 6 fits 3 people (vs 2), has 9 heaters (vs 7), runs at 3,400W (vs 2,600W), and has a wider interior at 56 x 41 inches (vs 46 x 41). Both use the same 120V/40A single-plug electrical setup, hemlock construction, and outdoor-rated design. Choose the Nature 5 for 2-person or solo yoga use. Choose the Nature 6 if you need room for 3 or want more heater coverage.
Nature Saunas are built for outdoor use with extra-thick weather-resistant walls, roof overhangs, protective heater covers, and 100X Stronger outdoor heaters. They also feature removable benches for hot yoga, which indoor models don't have. Indoor Medical Saunas have a wider feature range (silent heating, audio theater, etc.) but are not weather-rated. If you plan to place the sauna on a patio, deck, or backyard, choose a Nature model. If it's going in a room, garage, or basement, choose an indoor Medical model.
The Nature 5 is a dry infrared sauna only. It uses 7 full spectrum infrared heaters and does not include a steam stove. If you want a hybrid sauna that does both dry infrared and traditional steam, look at the Nature 7 or Nature 8 Plus. Those models include both infrared heaters and a steam stove, but they require 220V hardwired electrical and use cedar instead of hemlock.
The Nature 5 already uses Ultra Full Spectrum heaters that include red light wavelengths as part of the near-infrared spectrum. This provides some of the skin and surface tissue benefits associated with red light therapy during every session. For dedicated red light therapy equipment, browse our red light therapy collection.
947 lbs fully assembled. You'll need 2-3 people for assembly and a solid, level surface like a concrete pad, reinforced deck, or paver patio. The exterior footprint with overhang is 50 x 45 inches (about 4.2 x 3.75 feet). Make sure your surface can support the weight.
