Why 2 feet? don't standard appliances come with a 6 foot cord? it will only fall 4 feet into the tub at that point. if there is no receptacle present and the homeowner wants their precious flat screen tv while in the tub, they will probably run a zip cord type extension cord to the nearest receptacle. that being said you may as well give them the proper gfci receptacle. I'm kinda liking the glass idea brought up by Marc...however the nec is not a design tool right? maybe in the future bathrooms will have some type of dry compartment within the foot print to contain the tv and all associated wiring maybe the building codes will have something to say on this ?
