Some folks like it and well....the others won't buy it.
Just kidding, anytime you want to upgrade to a steam shower or multi jet shower...you get what "you" want.

Someone else will go back to a j-tub if they want one.
When I inspect a jacuzzi tub...you should see the black gook that comes out of the jets sometimes when they are not cleaned out properly. That is when no one wants a j-tub.
