The heat from the baths could be raising your body temp enough to kill off bacteria and is making you herx. I had to quit taking hot showers for the longest of time because of this, and have chosen to use the Epsom salt/peroxide foot soaks instead of the full baths.
If you didn't change anything else in your routines, and are still feeling poorly, assume you are herxing and increase your detoxing. It will likely help.
