New bath vanity will cover up 1/2 of 9" long x 2" deep supply register in floor (18" baseboard register vent), one of 3 supplies in master suite. Do you think it's easier to stack it despite the drywall/electrical issues or is it possible to modify/move the supply about 10"? Supply is in small bath space (10' x 5') but they would like to keep it for performance/comfort.
Thanks.
