About SaunaPlungeHub

SaunaPlungeHub is an independent review and comparison hub for saunas and cold plunges. We don't accept payment for placement, and no brand can pay to improve its Matrix Trust Score.

How the Matrix Trust Score works

Every brand's score (0-100) is calculated automatically from: product rating quality (up to 60 points), review volume (up to 20 points), active verified offers (up to 10 points), and certification/warranty data (up to 10 points). Scores update automatically as new data comes in.
