Golden Designs Forssa 3-Person Cabin Sauna
The Golden Designs Forssa is a spacious indoor traditional sauna built for a small family or couple. While marketed for up to four people, it comfortably fits three adults sitting upright.

SaunaGrade Buyer's Analysis
The Golden Designs Forssa Edition combines a Canadian Red Cedar interior with a Canadian Hemlock exterior finished in a clean stain, offering natural wood aesthetics and a pleasant aromatic experience. The dual-wood construction provides durability and visual contrast, featuring an all-glass front and right-side wall that let in plenty of natural light and keep the interior from feeling cramped.
Heating is powered by an included Harvia The Wall 8kW traditional sauna heater with built-in controls, which delivers reliable heat suitable for traditional water-on-stone steam sessions. Electrical requirements call for professional installation by a certified electrician due to the split-service layout: 240V at 40 amps for the high-draw heater, and a standard 120V at 15 amps for the interior LED control panel, chromotherapy lighting, built-in FM radio, and Bluetooth speakers.
At 75 inches wide, 48 inches deep, and 78 inches tall, this indoor unit fits well in finished basements, master bathrooms, or dedicated home gym spaces. The package includes practical accessories like a sandglass, bucket, scoop, and an interior backrest with accent lighting. Assembly requires basic carpentry skills and two people to manage the glass panels and heavy timber components, totaling 625 pounds of assembled weight.
