A generally rectangular open topped vessel with vertical walls around the periphery of a floor consisting of two integrally formed levels, the lower level being at one end providing a footwell and having a drain therein. Near the end of one side wall, in the area where the footwell is located, is a door opening. This door opening has a ferromagnetic faced door stop around the edge. A door is hingedly attached to the edge of the opening such that it swings horizontally inward towards the nearest adjacent end wall. The door has a flange along its two vertical edges and along its bottom horizontal edge. Mounted concentrically on the flange are two magnetic gaskets such that when the door is closed the gakets force a water tight seal with the ferromagnetic plate on the door stop. A second drain is located in the surface of the bottom door stop such that when the door is closed water in the vessel cannot reach the drain due to the sealing of the outer gasket. With the door open water will go down this drain before it reaches the door opening.
A water-tight, open-topped bathtub receptacle having a plurality of vertical side walls, a bottom and a major drain opening, and having in one vertical wall a doorway with a hingedly attached unitary inwardly opening door, a compressible continuous magnetic gasket and a cooperating ferromagnetic surface at cooperating margins of said door and doorway respectively, and an auxiliary drain outlet located in said wall at the bottom of said doorway and so disposed as to be sealed from the inside of said receptacle by said gasket while said door is in the closed position.
