What is a hot tub?

Healthy body and beauty in daily bath

A bicarbonate ion bath that has been developed from a thorough analysis of home-made natural carbonated springs (medical spas) in the country, and achieves the same neutral pH as the therapeutic springs and blood. The action of the active ingredient increases the warm bath effect, dilates the capillaries, increases blood flow, and improves metabolism.

When the hot tub is dissolved in hot water, fine carbon dioxide gas is generated. The carbon dioxide gas generated in the hot water is immediately neutralized to become neutral bicarbonate ions and hydrogen ions and dissolves in the hot water. If you can bathe in lukewarm water of 41 ℃ or less for 15 minutes, blood flow will rise and warm from the core of your body.

    The generated carbon dioxide gas dissociates into bicarbonate ions and hydrogen ions and dissolves in hot water, so you can enjoy the 24 time effect even after foaming. The same effect can be realized if the family who comes in later can cook it.

How to use the hot tub


Fill the bathtub in your home with a tablet. The home bath is about 200 liters, so it will be a 3 tablet.
