Mom's Laboratory was seen in the episode "The Lab of Tomorrow" as a lab that might possibly exist in the future. It is Mom's secret laboratory. She goes there whenever she wants to take a break from doing all of her housework.
Mom's Lab is essentially just a second kitchen with what seems to be a spa and a laundry room. She has a tanning lounge chair and the lab is run by a team of handsome scientists who wait on her hand and foot. Mom enters her lab by pulling the sink faucet, she then steps into the sink which sinks down like an elevator.
