depending on the type of whirlpool dropin or alcove .there should hopefully be a panel on the side of the tub ,or in front to access the tub spout an drain assembly as well as the pump so if there is ever problems you can get to it an make repairs . if this is not the case you will have to open up wall were tub is .also some tubs now have what is known as skirts it is removable an usually runs across the whole length of tub ,so you can get to mechanicals . hope this helps
