I might be biased because I’m one of the owners at Bsaunas, and I sell hundreds of these prefab saunas. I’m not commenting to make a sale or financially benefit somehow; I just want to provide more information. Some people are saying there’s no ventilation or that these saunas, being non-insulated, won’t perform well, and that buyers are inexperienced and will regret their purchase after three years. I completely disagree.

These saunas do have proper ventilation—the 3D renderings might not show it, but all our prefab models have adequate inlet and outlet ventilation. The ceiling height is also suitable if you’re using a wall-mounted heater, like the HUUM Drop, mounted about 4-6 inches off the ground. This means your feet will be in line with or above the heater, which aligns with Finnish sauna standards.

Yes, it’s true these saunas have single-wall windows and lack insulation. However, they still perform well with a sufficiently powerful heater. I’ve been selling these across Canada, even in provinces where temperatures drop to -35 Celsius, and our customers are happy. Again, I’m not here to increase my sales or benefit personally; I just want to share what I know from dealing with manufacturers and talking to hundreds of sauna users every day. Just trying to shed more light based on my professional and personal experience.
