Genius space-savers. These two ideas are no less than just that. One is this hideaway kitchen by Xera. The sink faucet folds down, allowing the countertop to slide over the unit when it's not being used.
The other is a floor-concealed tub. The slatted wood floor folds open to reveal a recessed bathtub. When it's not in use, look at all the extra floor space you have!! Beautiful.
