For the record, I usually stick the tub's gfi across the other side of the bathroom, and feed another receptacle outlet under the tub with the first one. (this isn't the sinks gfi, thats another story). I am just saying is accepted practice to do it the other way around, and that requires sombody to remove the access panel cover to reset the gfi. To have to climb a ladder to reach a gfi as the original poster was wondering about - I can find no reason in the code book to prevent this.
