Mustang, I would haveto agree with e57 and not have the switch for the shower to accessable. As for the tub switch I think it is done via a pressure switch, no electrical power here. What I normally do is to install a receptical under the tub near the motor (as they all come with a plug & cord) on the load side of a GFI receptical for resetting if needed. Most always the GFI is on the backside of an adjoining wall (toilet area, etc.).
