I'm buying a new apartment and I cannot easily modify the walls to add an additional electrical box. There's only one outlet and it's by the mirror over the vanity.
I want to install an electric toilet seat bidet but I don't want the aesthetic of the cord or loss of use of one of 2 outlets for this semi-permanent installation.
Is there a way to wire up a narrow extension cord to come out of the electrical box and straight down to the ground where I can plug in the bidet?
EDIT: Would it be a bad idea to build another GFCI box and route the cords together down the wall to this box?
