About HeatColdLab

HeatColdLab is a small, independent team that got tired of sauna and cold plunge shopping being harder than it should be. These are $1,000-plus purchases, often $5,000-plus, and the information that actually decides whether one works out (the circuit it needs, the real interior width, what the EMF report measured, what the warranty leaves out) is usually buried in a PDF nobody reads before checkout.

So we read it for you. Our focus is home heat and cold therapy gear: infrared and outdoor saunas, cold plunge tubs and chillers, and setups that combine the two.

How we research and compare

For every guide we pull the same documents: manufacturer spec sheets and installation manuals, electrical requirements, third-party EMF reports, warranty and return terms, and freight policies. We put them side by side, then read through owner reviews and expert walk-throughs to spot the problems that keep coming up. Where the published data is thin or contradictory, we say so instead of guessing.

We'll be upfront about one thing: unless an article says otherwise, we haven't physically tested the products we compare. Our picks come from documents and owner feedback, not our own sessions. The full method is on our How We Review page.

Who writes here

Our guides are edited by Steven Simmons, with research and fact-checking from the rest of the HeatColdLab Team.

What we won't do

• We don't accept payment for rankings, placements or reviews. Brands can't buy a spot on a list or see an article before it's published.
• We don't invent test results, "we tried it" stories or credentials.
• We don't give medical advice. When we cover health research, we link the studies and explain their limits.

How we make money

HeatColdLab is reader-supported. Some links on the site are affiliate links, so if you buy through one we may earn a commission at no extra cost to you. As an Amazon Associate we earn from qualifying purchases. Commissions never decide which products we recommend or in what order. Details are on our affiliate disclosure page.

Spotted a mistake?

Prices and models change constantly, and we'd rather be corrected than wrong. If you see an outdated spec, a broken link or a claim that doesn't match its source, tell us and we'll fix it and update the article date.
