Abstract:
A method of making a safe egress bathtub providing safe egress by reducing slide forces extended on a user's feet upon a slippery bathtub floor, wherein the formed bathtub has a limited rectangular footprint, and an optimized floor space is formed with a substantially planar base with a length and width that define the limited rectangular footprint and a front wall, a back wall, a first side wall and a second side wall integral with and extending substantially vertically upwards from the substantially planar base. Each of the front, back, first side wall and second side wall have minimal wall thicknesses to define the optimized floor space and the front wall has a substantially planar inwardly, cantilevered upper apron deck in a substantially parallel relation to the substantially planar base.

Claim (Index 16):
A safe egress bathtub comprising:\n substantially vertical back and front walls, first and second end walls and a flat bottom wall, wherein said walls comprise rigid material and are configured for entry and egress over said front wall and for said back wall to abut or be embedded in a room wall; said front wall having a top horizontal apron deck extending from an outer surface of said front wall toward said back wall, said top horizontal apron deck consisting of a flat top surface extending horizontally to a distal free end from which an inner surface of said front wall extends downwardly toward said flat bottom wall, wherein the horizontal extent of the top horizontal apron deck defines a thickness or width of a top of said front wall; said bottom wall extending to the inner surface of said front wall; respective inner corners formed by vertical ends of the first and second side walls of the bathtub, with vertical ends of the front and back walls, are substantially concavely rounded, and having an arc radius of about one half inch; respective inner corners formed between lower ends of the first and second side walls and the front and back walls are substantially rounded and joined to an inner surface of the substantially planar base also being substantially concavely rounded, and having an arc radius of about one half inch; and wherein the thickness or width of said front wall and the horizontal extent of said top horizontal apron deck are configured to obtain a straddle angle of egress over said front wall that is sufficiently small to minimize a horizontal component of force for reducing an incidence of slippage and falling when said bottom wall is wet during entry and egress.
