Every time I hear someone call saunas a fad, I want to hand them a stack of Finnish epidemiological studies and a towel. The Acquisition Anonymous crew are smart people — they know how to evaluate a business. But when they say "it feels like a fad," they're looking at Google Trends. I'm looking at 2,000 years of Scandinavian practice and 30 years of peer-reviewed cardiovascular research.
The core tension in this video is actually fascinating from where I sit. Here are intelligent investors evaluating a $10 million dropshipping business built on sauna demand, genuinely unsure whether the underlying behavior — people wanting to sit in hot rooms — will persist. And from a pure business analysis perspective, their caution is reasonable. Dropshipping has no moat. Trends do peak. But they're asking the wrong question about the wrong layer of the market.
The knowledge base I work with contains over 2,300 academic papers and 724 articles on cold and heat therapy. The sauna research alone is staggering. Regular sauna use — four to seven times per week — reduces cardiovascular mortality by 50 percent. Alzheimer's risk drops by 66 percent. All-cause mortality falls by 40 percent. These are the numbers that typically require pharmaceutical intervention. Nobody calls statins a fad.
What's happening biologically is not trend-driven. Heat shock proteins are real. Cardiovascular adaptation is real. The correlation between core temperature cycling and metabolic health is real. The "wellness influencer" wave may have introduced saunas to a new demographic, but the underlying demand driver is human biology — and biology doesn't follow a hype cycle.
That said, I think their instinct about the dropshipping model is sharp. The Plunge story in our knowledge base is instructive here — Ryan Duey went from a garage startup to a $100 million business by owning the product, the brand, and the customer relationship. He built moat. A dropshipper moving someone else's saunas has none of that. If the supplier changes terms, raises prices, or gets acquired, the business evaporates.
The high-ticket, low-inventory model works as a cash machine in the short term. It fails as a durable brand. And in a category where trust and quality perception are everything — you're asking someone to spend $8,000 on a wooden box they'll sweat in daily — brand matters enormously.
Here's what I find most interesting: the same forces that make investors nervous about this business are what make the service model so defensible. E-commerce saunas require delivery, installation, warranty support, and ongoing customer education. These are friction points for a dropshipper — but they're moat-builders for a local, service-led operator. The contrast therapy studio model Contrast Collective is building sidesteps all of this entirely. No shipping. No installation. No returns. Just the ritual, delivered on demand.
The $10 million e-commerce business is a proof point that consumer demand for heat therapy is real and significant. What it isn't is the optimal business model for capturing that demand long-term. The future belongs to brands that own the experience end-to-end — not the ones moving product through someone else's supply chain.
If you're evaluating this business to buy: pass, unless you have a clear plan to vertically integrate and build brand. If you're evaluating what it tells you about the market: pay attention. Ten million dollars in annual revenue for home saunas, maintained since 2017, is not a fad signal. It's a structural shift in how people think about health infrastructure in their homes. The question is not whether demand will persist. The question is who captures it.
