Clear standards, explicit tradeoffs.

Research approach

We use a mix of manufacturer documentation, product pages, public specifications, primary research, public health guidance, and editorial synthesis. For health and safety content, we prioritize primary studies and established medical guidance over wellness marketing.

How we evaluate products and brands

We judge products and brands on fit, not on abstract prestige. A great heater for a dedicated backyard build can still be a bad recommendation for an apartment buyer. When a brand is hard to source, overpriced, poorly supported, or too marketing-heavy, we say so directly.

Updates and corrections

We update guides when product availability changes, new research materially changes the answer, or a page is otherwise outdated. If a factual issue is reported, we correct it as quickly as possible and prefer updating the page over silently letting stale guidance linger.

Health and safety content

Sauna is powerful enough that bad guidance can matter. Our safety content is written conservatively and is meant to help readers decide when to slow down, get clearance, or skip the heat. It is not individualized medical advice.

What independence means here

Independence does not mean having no commercial interests. It means not letting those interests dictate the verdict. If a cheaper option is the better option, that should be the recommendation.

Paid relationships

We may accept paid brand profiles, sponsorships, and affiliate relationships. We label them clearly. Some brands pay an annual fee so we can keep a profile current with product, pricing, warranty, distribution, and approved image information. On those pages, the disclosure explains that the profile is actively maintained and that Sauna Guide reviews every change.

A brand may supply source material, approved assets, and supported factual corrections. It cannot edit or publish the page, approve our copy, buy a ranking or positive verdict, remove a caveat, or guarantee inclusion in a comparison or guide. Broader collaborations are considered separately and only where they fit the buyer's question. Sauna Guide keeps the final editorial call throughout.

Local installer shortlists and referrals

Local pages distinguish facts confirmed directly with a provider from facts drawn from public company sources. We record the check date, service area, project types, documented manufacturer relationships, installation scope, sources, and important unknowns. A business can be excluded when we cannot verify enough buyer-relevant information.

Payment, pilot participation, or referral status never changes shortlist order or buys a positive description. Local lists are ordered by a disclosed neutral rule. Paid or tracked partner links use a sponsored-link label. A provider may correct a factual error, but cannot buy placement, remove a caveat, or prevent us from listing a better-fit alternative.
