FERMENTATION BATH
About the Sawdust Bath
A hot bath that uses the fermentation heat produced by microorganisms instead of heating directly with fossil fuels.
WHAT IS IT?
Born from the work of nature,
Soft warmth.
Ohtaka Enzyme stock solution is added to coniferous sawdust and fermented using the action of microorganisms. It is a dry hot bath experience where you will wrap your body in fluffy sawdust and feel the warmth and scent of wood.
