Welcome to our forum.
You will find YOUR perfect temperature. For me, it's 101 (100 in the summer)...my husband will adjust the tub to 102. Believe it or not, I can detect the one degree temperature increase without even looking at the control panel ! ...and it doesn't make me happy when he does that
We like 100 for the summer, we've only had it for two weeks but I imagine, come winter I'm gonna want 104, I'm sure Adam will push for 102 though.
Do you keep the tub at these temps even when you are not using the tub?
