KLS Co., Ltd. has been producing infrared saunas for years, and the Kanlanth 1-Person model focuses on a specific problem: getting genuine heat therapy into a small home without a massive footprint. At 33.86 inches square, this unit fits into a corner or spare bedroom without dominating the space. The real draw is the 1200W power spread across seven low-EMF carbon crystal heating plates, which deliver 360-degree heat rather than just blasting one side of your body.

The Canadian Hemlock construction is solid, with a mortise and tenon joinery system that snaps together in under an hour without tools. You sit inside and the cabin reaches up to 140°F, which is hot enough for a deep sweat session but not punishing. The 6mm tempered glass door holds the heat well. For a single person up to 6.2 feet tall, the interior feels spacious enough to shift positions. The seat supports up to 600 pounds, so it’s built for durability.

One thing to note: this is a dry sauna. You don’t pour water over rocks here. The infrared heat penetrates muscles directly, which is great for recovery after workouts or just unwinding. It draws 1200 watts, so expect a moderate bump on your electricity bill if used daily. Assembly is straightforward, but the unit weighs over 100 pounds, so having a second person to lift it into place helps.
