Water Maintenance
We recommend keeping the pH value of the water in the tub between 7.2 and 7.8. A pH value outside of this range can shorten the service life of the tub and cause irritation or damage to your skin. Any damage to the tub caused by too high or low pH value will not be covered by the manufacturer’s warranty. We suggest using a pH test kit to routinely test the water quality before using it.
