We are committed to our customer's safety and healthy home environment.  The State of California requires manufacturers & retailers to disclose special warnings for products that contain substances or chemicals known to the State of California to cause cancer or reproductive harm.  In testing, we have learned that our electronic bidet seats hold lead and lead compounds below the safe harbor limits that require us to disclose this warning.  We opt to still share this warning so our customers can use caution & wash hands well after handing installation parts.  For more information. https://www.p65warnings.ca.gov/
