Welcome to our forum.
Small children 5 years and under should not be in spa when water is over body temperature.
Why? And, please, don't just say because the CPSC says so. How about some data that will show why my 4 and 5 year old nephews shouldn't stay in my tub the 2+ hours they usually do at 104+ ??Seriously...Drewski
I belive its due to body size and mass. Typically the size of a child 5 years old and younger can overheat rapidly.
He told us that tubs should never be set over 104 unless we wanted to kill brain cells.
