I am installing ikea bathroom vanity with 4” clearance between drawer back and wall.
I guess I must shorten water supply and drain stub-outs, correct?
Ikea p-trap is 1.25” while installed drain adapter and old p-trap is 1.5”.
The installed elbow attached to the drain adapter does not fit behind the drawer.
How can I make this fit?
Should I install new drain adapter of size 1.25” or 1.5”?
