Relax by Rainshower is your solution to cleaner, healthier water in the bath. A simple pull through the water reduces the presence of harmful chlorine that can dry out and damage skin and hair.


Dechlorinate your bath water with the Rainshower Relax by placing it into the tub and pulling it through the water with the attached 12-inch cord for 5 to 7 minutes or longer. As chlorinated water flows through the filament the dissimilar metals in KDF®-73, (copper and zinc), create a galvanic or electrolytic reaction which causes the two chlorine ions to form a harmless chloride. It changes the chlorine from an element into a harmless compound.

In addition to the KDF filament, the Relax also uses our specially washed and sun dried quartz crystals to help "energize" the water by reducing the water's surface tension. This allows for an increase in sudsing and lathering of soaps and shampoos. As a result, the water has a "lighter" feel, similar to the feeling of softened water.

    I have shared this with Nephew for his children so that it can be non-toxic. My other Nephew because he dips in freezing cold water, and I personally do not want chlorine in their skin. Thank you Rainshower
