A revolutionary showerhead
with two types of bubbles for
even more beautiful skin.

After analyzing the effects of water on the skin,
ReFa has developed an entirely new kind of
shower head. The ReFa FINE BUBBLE ONE
creates two types of bubbles to gently cleanse
without causing any stress to the pores of the skin
and scalp: ultrafine bubbles and microbubbles.
By embracing the entire body with warmth and
comfort as it cleanses, the ReFa FINE BUBBLE ONE
elevates bathing to a beautiful art form.

The science of ultrafine
bubbles and microbubbles.

To prevent shower water from becoming an irritant to your skin and hair, ReFa applied breakthrough Japanese fine bubble technology to the design of this revolutionary showerhead. Far smaller than the bubbles we’re used to seeing when we bathe, ultrafine bubbles and microbubbles have a unique cleansing capability that transforms bathing into a luxurious beauty routine.

Hydrophobic interaction:
the ultimate cleansing mechanism.

01. Hydrophobic dirt particles attach to the hydrophobic surfaces of the bubbles. 02. By absorbing these dirt particles while floating to the skin’s surface, the bubbles gently remove them from the skin.

Two kinds of fine bubbles will gently cleanse
your skin and fill your body with warmth and comfort.

ReFa's technology enables this device to generate two kinds of bubbles for even more beautiful skin. Showering with ultrafine bubbles and microbubbles removes dirt and grime from the pores of your skin and scalp gently, comfortably, and thoroughly. Fill your bathtub with ultrafine bubbles and microbubbles, and envelop your body in the warmth and comfort of a silky-soft fine bubble bath. Enjoy the comfort and relaxation of an at-home spa experience, brought to you by the science of bubbles.

ReFa’s proprietary Double Cavitation structure instantly
delivers a multitude of fine bubbles to your skin.

A unique structure that uses pressurized dissolution and double cavitation to instantly generate ultrafine bubbles and microbubbles. We calculated the size and number of holes in the showerhead to achieve a silky-soft flow of water that's gentle on the skin and hair.

Double your cleansing with two types of bubbles.

Every time you shower with the ReFa FINE BUBBLE ONE, two kinds of bubbles wash away dirt particles from your scalp and pores—leaving your skin looking clean and radiant.

Immerse your entire body in warmth and comfort.

Place the showerhead in your bathwater to enjoy a silky smooth bubble bath. Two types of bubbles envelop your skin in warmth and comfort while gently removing dirt and grime from your pores.

Hydrates as it cleanses.

With its two types of bubbles, the ReFa FINE BUBBLE ONE washes away dirt particles with water that feels as smooth as silk—and provides the skin with vital hydration.

The water content of the skin’s surface immediately after use was about 22% higher than it was before use.

Subjects: 17 men and women aged from 26 to 60.
Test method: Washed the subjects' hands with soap and let them acclimate in a 20°C ± 1°C room for 20 minutes. Showered the backs of the subjects' hands (temperature: 36.5°C ± 0.5°C; flow rate: 5.00 ± 1 mL/min.) for 40 seconds with the bubble feature (set to level 2) and without it (set to OFF), then measured the water content of the skin's surface.

Reduce water usage by up to 40%

The ReFa FINE BUBBLE ONE enables you to conserve more water than you would with a conventional showerhead.

Easy to turn on and off

Turn the dial of the built-in bubble control function to switch the bubbles on and off and easily adjust the water pressure.
