Benovo vs Duthss Sauna Comparison
Person Capacity
You need to decide how many people will use the sauna together. The Benovo is designed for 6 to 8 people. Its square footprint provides more floor space for larger groups. The Duthss supports 4 to 6 people. Its barrel shape offers a more compact interior. If you frequently host family gatherings or want extra room to stretch out, the Benovo has the clear advantage. The Duthss is better suited for couples or small families who prefer a cozier environment.
Heater Power
Heater power determines how quickly the sauna reaches your desired temperature. The Benovo includes an 8KW electric stove. This higher wattage can heat the larger volume of air more rapidly. The Duthss uses a 6KW electric heater. While sufficient for its smaller size, it has less raw power. If you want faster heat-up times or plan to use the sauna in colder weather, the Benovo provides a practical edge. The Duthss heater is adequate for its specific capacity.
Wood Type
The type of wood affects durability, scent, and heat retention. The Benovo is constructed from Canadian Cedar. Cedar is known for its natural resistance to rot and insects, along with a distinct aromatic scent. The Duthss uses Canadian Hemlock. Hemlock is a durable softwood with a light color and subtle grain, but it lacks the strong aromatic properties of cedar. If you prefer a fragrant sauna experience, the Benovo has the advantage. Hemlock is a solid, neutral choice for traditionalists.
Design and Shape
The physical shape changes the interior layout and exterior look. The Benovo is a square, house-shaped room with straight walls. This design maximizes usable floor space for multiple benches. The Duthss is a classic barrel sauna with curved walls. The curved design promotes efficient heat circulation and has a traditional aesthetic. If you value maximum seating space and a modern look, the Benovo wins. If you prefer a traditional, space-efficient barrel shape, the Duthss is the better choice.
Dimensions and Footprint
You must ensure the sauna fits your available outdoor space. The Benovo measures approximately 78.7 inches by 78.7 inches with a height of 96.5 inches. This is a larger structure requiring more yard space. The Duthss measures 71 inches by 71 inches with a height of 71 inches. It has a smaller, more compact footprint. If you have limited patio or garden space, the Duthss is easier to place. The Benovo requires a significantly larger area for installation and access.
Choose your ideal outdoor sauna
Large group users needing space
The Benovo fits 6 to 8 people. Its 78.74-inch square footprint offers more floor space than the Duthss. This layout accommodates larger groups comfortably. The 8KW heater provides strong heat output for the volume. You get a dedicated room style with a sloped roof for weather protection.
Couples or small families
The Duthss supports 4 to 6 people. Its 71-inch barrel shape creates a cozy atmosphere. Two facing benches are ideal for couples or small families. The 6KW heater is sufficient for this smaller volume. The curved design promotes efficient heat circulation for a traditional dry sauna experience.
Users preferring traditional barrel style
The Duthss features a classic barrel design with metal hoops. This shape is traditional and aesthetically distinct. It uses Canadian Hemlock, which has a light natural tone. The shingle roof adds to the classic look. The built-in controls simplify operation for users who prefer simplicity over complex systems.
