I got a call for another 120V spa. This time, the recep will be located in a wet area instead of a damp area, so I need a bubble cover. Unfortunately, the unit has a GFCI cord end. Why is this? You have to have a GFCI recep anyway. I guess for the older homes that were built prior to GFCI outlets being required outside. However, it has a NEMA 5-20P end, so those older homes probably wouldn't have the 20A recep that would accept both a NEMA 5-15P and the NEMA 5-20P. Anyway, the cord end is about 4.75" tall from center of plug terminals, to the ottom of assembly. It is 2 3/8" wide, and 1 3/4" deep. I need a single gang bubble cover that hangs down at least two or three inches below the bottom of the bell box.

Any suggestions, besides changing the cord end?
