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 for hidden hair tool storage. 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.
