A bathtub assembly that can be raised and lowered has a bottom and a lift plate with scissors-like guide frames positioned between them, which said frames guide the lift plate vertically. Two collapsible hoses or bellows, made of material that bends but does not stretch, are sealed at the ends, one end being attached to the lift plate and the other to the bottom. The hoses or bellows 20, are connected by means of connection hoses and a manual valve to the house water supply line.
