How we research and score infrared saunas

We'd rather tell you exactly how our recommendations are made than imply something they aren't. Here's the process behind every guide, review and calculator on Infrared Sauna Guide.

What we do (and don't do)

Infrared Sauna Guide is a research-based buyer's guide. We don't run a lab, and our reviews are not hands-on tests. Instead, for every model we:

• Start from the manufacturer's spec sheet: capacity, dimensions, heater count and type, wattage, EMF claims, wood species, electrical requirements.
• Cross-check with independent reviews from publications that do test hands-on, and note where their results differ from the marketing claims.
• Read owner reports (forums, retailer reviews, support threads) for the problems that only show up after months of use: slow heat-up, heater failures, wood cracking, support response times.
• Flag uncertainty. When a spec can't be confirmed, or sources disagree, we say so rather than guess.

Each model page lists the sources we relied on.

How the 10-point score works

Every model gets four sub-scores, each out of 10:

• Heat: heater count, wattage and placement, max temperature, and how quickly cabins reach operating temperature per owner reports.
• Build quality: wood species and construction, glass quality, warranty length, and maker reputation.
• Features: EMF level, red light/chromotherapy, sound system, controls, and what is included vs. upsold.
• Value: typical street price against what you get, including warranty and running costs.

The overall score is a weighted blend of the four, rounded to one decimal, plus small adjustments for reliability and support reputation. A 9+ is exceptional, 8–9 is a strong buy for the right yard, and under 7.5 means real compromises.

A higher score doesn't mean it's the right sauna for you. A 9.0 premium 2-person cabin is a bad buy if you only have a closet to put it in. That's why we built the space-fit checker.

Prices

Prices are typical US street prices at the time of our last update and are shown as ranges because saunas are discounted heavily and often. Always check the current price on the retailer page.

Affiliate links and independence

Infrared Sauna Guide is reader-supported. As an Amazon Associate we earn from qualifying purchases made through our links, at no extra cost to you. Commissions never decide which products we recommend or how they are ranked. Brands cannot pay for placement, and we don't accept free products in exchange for coverage.

Updates and corrections

We review our main buying guides at least quarterly and whenever a significant model launches. Each page shows its last-updated date. Spot an error? Tell us and we'll fix it.
