When selecting an infrared sauna capable of accommodating 24 people, the key considerations shift significantly from smaller models. While most options cater to two or four users, these large-scale units focus on maximizing space, energy efficiency, and advanced features suitable for commercial or community use. Among the top picks, the Woodbridge Infrared Sauna Room stands out for its durable Japanese cedar construction and health features, making it ideal for wellness centers. Meanwhile, the i-THERA-U Infrared Sauna Box offers a portable, feature-rich solution that balances comfort and flexibility, though its setup can be complex. The MNLR 2 Person Infrared Sauna and other smaller units are excellent for personal use but fall short in size, making them unsuitable for 24-person capacities. Here, I focus on models that truly scale for large groups, weighing their build quality, features, and practicality.

More Details on Our Top Picks
Woodbridge Infrared Home Sauna Room for 2 Persons with Japanese Cedar, Bluetooth, Red Light Therapy, and Intelligent Control Panel
This sauna excels in providing a luxurious, durable environment for two users at a time, with high-quality Japanese cedar and advanced features like red light therapy and Bluetooth speakers. Compared with other compact units, its modular design allows easier assembly and better longevity, but its size clearly limits its capacity for 24 users at once. For larger groups, this model can serve as a premium addition to a wellness facility, but it’s not scalable alone. The need for a dedicated 20AMP circuit and its indoor-only restriction are notable tradeoffs, yet it’s ideal for high-end small group therapy or boutique spas.
Pros:- Durable Japanese cedar construction enhances longevity
- Advanced health features like red light therapy
- Bluetooth speakers and customizable lighting add relaxation value
- Relatively easy to assemble compared to larger commercial units
Cons:- Limited to two persons at a time, not suitable for 24
- Requires a dedicated 120V/20AMP circuit
- Indoor installation only, space constraints
Best for: Boutique wellness centers or upscale home gyms seeking premium features for smaller groups
Not ideal for: Large-scale commercial facilities or events needing immediate capacity for 24 people
- Dimensions:47″ W x 43″ D x 74″ H
- Material:Japanese cedar
- Heaters:8 infrared carbon heaters
- Maximum Temperature:149°F
- Electrical:120V/20AMP circuit
- Lighting:7-color LED strip
Our verdict“A top-tier, small-scale luxury sauna best suited for high-end wellness spaces that prioritize quality over capacity.”
MNLR 2 Person Infrared Home Sauna with Top Vent & Flame-Retardant Design
While primarily designed for two, the MNLR sauna stands out thanks to its low-EMF full-body heating, smart controls, and ambient lighting, making it a solid choice for small group therapy or private wellness. Compared to larger models, its compact size means it can be incorporated into a larger facility as a shared feature, but it won’t meet the capacity needs of 24 users simultaneously. Its relatively straightforward assembly and modern features make it appealing for clinics or upscale gyms wanting a reliable, safe option, but the capacity limits its use for large gatherings.
Pros:- Low-EMF infrared heating ensures safety
- Smart app controls for easy customization
- Ambient RGB lighting enhances relaxation
- Compact size fits into various indoor spaces
Cons:- Limited to two persons, not suitable for 24
- Assembly can take around an hour
- Indoor use only, no portability
Best for: Wellness centers seeking a high-quality, space-efficient sauna for small groups or private settings
Not ideal for: Large capacity requirements or outdoor installations
- Dimensions:47.2″ W x 39.3″ D x 72.8″ H
- Power:1500W
- Temperature Range:64°F-149°F
- Material:Wood with flame-retardant features
- Lighting:RGB ambient with red light
- Control:LCD panel and WiFi App
Our verdict“A premium, space-efficient sauna ideal for private or boutique wellness settings, but not scalable for large groups.”
I-THERA-U 2 Person Portable Infrared Sauna with Red Light Therapy
This portable option combines dual steamers and red light therapy, offering a versatile wellness experience for two users. Compared to fixed large saunas, its portability is a major plus, but the size still limits its use for 24 persons at once. Its quick setup and foldable design make it attractive for smaller facilities or temporary setups, but it’s not practical for continuous large-group sessions. The need for separate outlets for steamers and potential assembly challenges are notable, though its ability to incorporate steam and light therapy makes it stand out for niche uses.
Pros:- Portable and easy to fold for transport
- Dual steamers provide rapid, even heat
- Red light therapy enhances skin and muscle recovery
- Remote control and included folding chair
Cons:- Limited capacity—only for two
- Requires separate outlets for steamers
- Assembly might be complex for some users
Best for: Temporary wellness setups or facilities needing portable solutions for small groups
Not ideal for: Permanent large-scale installations for 24 persons
- Dimensions:71″ x 49″ x 36″
- Steam Power:1200W each, 2 steamers
- Light LEDs:160 LEDs (660nm & 850nm)
- Timer:99 minutes
- Material:Waterproof stainless steel
- Included:Remote, folding chair
Our verdict“A flexible, portable sauna suitable for small groups or temporary wellness activities, but not for large-scale capacity needs.”
i-THERA-U 2 Person Infrared Sauna Box with Red Light Therapy and Steam Function
This large, spacious model integrates infrared red light therapy with steam functions, making it a comprehensive wellness device for two users. Compared to smaller or less equipped units, it provides a high-end experience with durable insulation and dual steamers, but its size and setup complexity make it unsuitable for immediate large-group use. It’s ideal for facilities that want a versatile, high-quality sauna for a few users at a time, with potential scalability through multiple units. Its detailed installation requirements and space needs are notable tradeoffs, but the combination of features offers a premium experience.
Pros:- Spacious design with dual steamers
- Infrared red light and steam integration
- Remote control and included folding chair
- High-quality waterproof insulation
Cons:- Requires significant space and setup time
- Assembly can be complex
- Not designed for immediate large-group capacity
Best for: Upscale clinics or wellness centers seeking a multi-function sauna for small groups
Not ideal for: Immediate large capacity needs for 24 persons
- Dimensions:71″ x 49″ x 36″
- Steamers:2 x 1400W/3L
- Red Light Wavelengths:660nm & 850nm
- Material:Stainless steel, waterproof insulation
- Accessories:Remote, folding chair
Our verdict“A premium, multi-function sauna suited for focused small-group therapy, offering versatility but not immediate large-scale capacity.”

How We Picked
To identify the best infrared saunas for 24 persons, I evaluated models based on size, build quality, features, ease of assembly, and overall value. I prioritized units explicitly designed for large groups or commercial settings, rather than smaller personal models. Each product was compared directly against others in terms of capacity, durability, and added functionalities such as red light therapy, steam features, and smart controls. I also considered potential tradeoffs such as installation complexity, space requirements, and ongoing energy costs. This approach ensures that each recommendation aligns with the needs of facilities or large gatherings, rather than individual or small-family use.

Factors to Consider When Choosing Infrared Saunas For 24 Persons
Choosing a sauna for 24 persons involves balancing space, durability, and advanced features. Unlike smaller units, these large-scale saunas must prioritize construction quality, energy efficiency, and ease of maintenance. The capacity requirement means selecting models designed for commercial or community use, often with dedicated electrical setups and space considerations. Consider whether you need additional wellness features like red light therapy or steam, which enhance the experience but can add to setup complexity. Ease of assembly and retrofit options are also critical, as these units typically require professional installation and significant space planning.Size and Capacity
Size is the most obvious factor for a 24-person sauna. Models explicitly designed for large groups or commercial settings will have dimensions that accommodate many users simultaneously. Remember that a true capacity of 24 requires a very spacious interior, often exceeding 100 square feet, with sufficient headroom and seating arrangements. Smaller units, even if they are labeled as ‘large,’ may only serve 4-6 people, so always verify capacity specifications carefully.
Material and Build Quality
Durability will determine the longevity of your investment. High-quality woods like Japanese cedar or heat-resistant tempered glass are common in premium models, offering both aesthetic appeal and resilience. Commercial settings demand robust construction that withstands frequent use and cleaning. Additionally, insulation and waterproofing are critical for energy efficiency and safety, especially in units with steam functions or red light therapy.
Features and Wellness Options
Features like red light therapy, Bluetooth speakers, ambient lighting, and steam functions elevate the wellness experience. These features are more common in premium models and can justify higher costs, but they also require careful electrical planning. Decide whether these add-ons are essential for your environment or if you prefer a more straightforward design focused on capacity and durability.
Electrical and Space Requirements
Large saunas often require dedicated circuits—typically 20AMP or higher—and specific electrical setups. Professional installation is usually necessary, especially for models with multiple heaters or steam functions. Ensure your space can accommodate the sauna’s dimensions and has suitable ventilation and electrical infrastructure to support ongoing operation.
Frequently Asked Questions
What size should I look for when choosing a sauna for 24 people?
For a group of 24, you should look for models with a minimum interior space of around 150 to 200 square feet, with high ceilings and multiple seating levels to maximize comfort. Many commercial-grade units are modular or custom-built to fit this capacity, so size is the primary consideration. Avoid smaller models marketed as ‘large’—verify actual dimensions to ensure they meet your capacity needs.Are large infrared saunas energy-efficient?
Large infrared saunas tend to consume more energy due to increased heater wattage and longer heating times. Choosing models with efficient insulation and programmable controls can help mitigate energy costs. However, expect higher utility bills compared to smaller units, especially if used frequently in a commercial setting. Proper electrical setup and maintenance also influence overall energy efficiency.Can these saunas be used outdoors?
Most large-scale infrared saunas are designed for indoor installation due to electrical and environmental considerations. Outdoor use is possible if the unit is specifically rated for weather resistance and if proper sheltering is provided. Always check the manufacturer’s specifications—outdoor installations often require additional weatherproofing and professional setup.What features are most beneficial for large-group wellness?
Features like multiple heaters, steam functions, red light therapy, and ambient lighting enhance relaxation and health benefits, making them worthwhile for large groups. However, these features can add complexity and cost, so evaluate whether they align with your wellness goals and budget. Advanced controls and remote operation are also valuable for managing large sessions efficiently.Is professional installation necessary for large saunas?
Yes, most large-capacity saunas require professional installation due to their size, electrical requirements, and complexity. Proper setup ensures safety, complies with electrical codes, and maintains the sauna’s longevity. Attempting DIY installation can lead to safety hazards and may void warranties, so hiring qualified technicians is strongly recommended.Conclusion
For buyers managing a large wellness facility, community center, or commercial spa, models like the Woodbridge Infrared Sauna Room or the i-THERA-U Sauna Box provide robust capacity and premium features, though they demand space and professional setup. Small-scale boutique owners or private practitioners should consider high-end, smaller units like the MNLR 2 Person Sauna or the Portable I-THERA-U for flexibility and luxury. Ultimately, the choice depends on your capacity requirements, budget, and desired wellness features—larger, more durable units for continuous group use, or more feature-rich, compact options for specialized services.”
