A 4 in. x 4 in. x 2 in. PVC DWV 45-degree H x H x H Wye fitting looks like it was meant to store hair tools instead of connect plumbing pipes! The large opening is perfect for storing a hair dryer, while the small opening is just the right size for holding a curling iron or straightener.
The fitting is sturdy enough be placed on a vanity top without worrying that it will topple over, or you could mount it inside a cabinet using a couple of screws. You could also spray paint the hair tool holder to match the décor in your bathroom, but we think the white fitting looks just fine as is.
