I finished the new bathroom door today. It's a variation of a "panel" door, except it's central spar is a wavy mirror I got from IKEA and the "panel" part of the door are punched aluminum panels from Lowes.

The inside/bathroom side of the door
The new door before finishing; you can see the inset area where the mirror sets so it will be flush with the wood frame of the door.
The old door & mirror
The back of the door has a central oak accent plus four standoffs for a towel rail I have yet to install.
Other cool trivia: the old door (without the mirror) weighed 26 pounds. The new door weighs 16 pounds and looks much
cooler! It's nice when it comes out looking exactly like I'd planned!
