Smartmak vs Duthss Key Differences
Heating type
The Smartmak uses far infrared carbon panels with 660nm red light therapy. It reaches high temperatures quickly with 1600 watts of power. This approach focuses on deep tissue warmth and skin benefits without heating the air as much. The Duthss relies on a traditional 6kW electric heater that warms sauna stones. This creates a dry heat environment suitable for steam-style sessions. You choose infrared for targeted therapy or traditional heat for classic sweating and muscle relaxation. Each method offers a distinct physical experience based on how the heat is generated and distributed.
Person capacity
Capacity is a major differentiator between these two units. The Smartmak is designed strictly for two people. Its interior dimensions of 47.28 by 35.46 inches provide enough room for a couple or two friends to sit comfortably. The Duthss offers a much larger footprint, accommodating four to six adults. With dimensions of 71 by 71 inches, it includes two long facing benches. This makes the Duthss better for families or group sessions. If you often sauna with others, the Duthss provides significantly more shared space.
Placement
Location flexibility matters for many buyers. The Smartmak is an indoor portable unit. You can move it from room to room easily after the quick five-minute setup. It does not require permanent installation or heavy structural support. The Duthss is an outdoor barrel sauna made for backyards, patios, or garden spaces. It requires a stable outdoor foundation and access to a 220V power supply. You cannot use the Duthss indoors due to its size and ventilation needs. Choose Smartmak for indoor convenience or Duthss for dedicated outdoor relaxation.
Build material
Construction materials affect durability and aesthetics. The Smartmak uses a metal pipe structure covered with fabric panels. It includes transparent windows and double-sided zippers for access. The design prioritizes portability and ease of storage when not in use. The Duthss is built from Canadian hemlock wood with tongue-and-groove panels. Exterior metal hoops reinforce the curved barrel shape. It features a black asphalt shingle roof and a tempered glass door. The wooden build offers a more permanent, traditional sauna appearance compared to the fabric tent style of the Smartmak.
Power requirements
Electrical needs vary significantly between these models. The Smartmak operates with standard 1600-watt power, which is typical for portable infrared units and easier to integrate into home circuits. The Duthss requires a dedicated 6kW system at 220V. This higher voltage demand means you may need to install a new circuit or upgrade your electrical panel. The 220V requirement also limits where you can place the Duthss. If you already have a 220V outlet, the Duthss is ready. Otherwise, the Smartmak presents fewer electrical hurdles.
Which sauna fits your lifestyle?
Small space renters needing portability
The Smartmak measures 47.28 inches by 35.46 inches and stands 63 inches tall. Its portable tent design fits easily in any room. You can set it up in five minutes using the metal pipe structure. It includes foldable chairs and an anti-slip mat. This compact size allows you to move it effortlessly between rooms.
Groups wanting traditional outdoor heat
The Duthss barrel sauna seats four to six people comfortably. It measures 71 inches on all sides, creating a spacious interior. The 6kW heater with 220V power supports traditional dry sauna and steam-style use. Two long facing benches accommodate couples or families for shared group sessions in your backyard.
Users seeking infrared therapy benefits
This model uses far infrared carbon panels with 660nm red light therapy. The 1600 watts of power heats up quickly for deep tissue warmth. It focuses on skin benefits and relaxation without heating the surrounding air as much. The transparent windows and LED reading light enhance your personal spa experience.
Homeowners desiring durable wood construction
Built from Canadian hemlock, this sauna features tongue-and-groove panels and exterior metal hoops for reinforcement. The black asphalt shingle roof protects the wood from rain. An 8mm tempered glass door brings in natural light. The sturdy wooden structure offers five-year support, ensuring long-term durability in outdoor residential spaces.
