Does it create a large enough hot spot for large females though? I'm just confused on what to get so many people use different sizes and my house also gets down to the 67-70 range in winter.

The tub size is 34" 17.5" x 5.3" and AP said they can fit any size I just need to tell them before it's manufactured.
