Courses
Learn alkaline bathing. Start with the free video.
Our Homebathing course and the Bathmaster training are currently only available in German. We are planning to launch them in English in mid-2027. Until then, Gunther explains how long alkaline bathing works in a free English video — no sign-up needed.
Free online information
How it works. Three levers, then the video.
An alkaline bath is water with carbonates — and three settings decide what happens in it: pH, temperature and time. That’s all you set. In the video, Gunther explains the ideas behind it: over-acidification as a model, the skin as the third kidney and why the long bath matters.
pH 9.5
The starting value we recommend. You measure it with test strips and adjust it with food-grade carbonates.
Slightly below body temperature
The water stays slightly below your body temperature — this outward gradient is the engine, not the warmth.
Up to twelve hours
Built up step by step: 1 h → 6 h → 12 h. Shorter sessions and foot baths are a way in, too.
Playing connects to YouTube (youtube-nocookie.com). English subtitles are switched on.
Bathmaster, not a doctor. Everything here shares experiential knowledge — no medical advice, no promise of healing.
