Handicap-accessible bath facility

A handicap-accessible bath facility formed in a conventional room having room walls, a ceiling and a floor, said handicap-accessible bath facility comprising:

• a planar modular wall having a length which is less than a length of a first room wall for extending between second and third room walls which are perpendicular to, and at the ends of, said first room wall and having a height which is less than a height of said existing room extending from said floor to said ceiling, said modular wall being hollow for receiving therein utility liens for servicing a sink, and a shower mounted adjacent to said modular wall, said modular wall being mountable in said existing room with a bottom edge resting on said floor and a first end edge abutting said second room wall so that said modular wall extends perpendicular to said second room wall with a second edge being spaced from said third room wall opposite to said second wall;
• a rectangular, relatively flat, shower base molded of a single piece of non-porous material to form a flat bottom surface for resting on said room floor, said shower base having a drain hole therein for allowing drain water from said shower to pass therethrough, a top surface of said shower base being molded to form a depression surrounding said drain hole for channeling water contacting said top surface at said depression into said drain hole, said top surface of said shower base being molded to form a ramp at a ramp edge thereof, said ramp leading upwardly from the bottom surface of said shower base at said ramp edge to a water-retaining barrier line on the top surface at a height of at least 1 inch above said surface across said shower base, said water retaining barrier line being positioned between said ramp edge and said depression and being spaced from said ramp edge not less than 3 inches, said depression beginning approximately at said barrier line, said shower base being of a size for fitting snugly between said modular wall and said first room wall when lying with said flat bottom surface thereof on said existing room floor with a second shower-base edge thereof abutting against said second room wall and said ramp edge being located near said second end edge of said modular wall, said ramp edge having a length at least as great as the width of a wheelchair but the length of said shower base (the distance from said ramp edge to said 2d shower base edge, which is approximately the same as the length of the modular wall), and the length of said depression (approximately the distance from said barrier line to said 2d base edge) being substantially greater than the length of said ramp edge;
• wall panels mountable on surfaces of said first and second room walls and a shower side of said modular wall within a shower compartment defined by these surfaces;
• engagement means for engaging said wall linings to said shower base such that water in said shower compartment at said engagement cannot escape from said shower compartment between said wall linings and said shower base;
• whereby said handicap-accessible bath facility can be mounted in an existing room and a handicapped person in a wheel chair can enter said shower compartment by rolling up said shower-base ramp to be positioned over said shower base depression which channels water from said shower head into said drain hole, said water retaining barrier line preventing water from leaving said shower compartment at said ramp edge of said shower base.

A method of constructing a handicap-accessible bath facility in an existing room having room walls, a ceiling, and a floor said method comprising the steps of:

• placing a rectangular, relatively flat, shower base in a corner of said existing room with a long edge of said shower base contacting a first existing wall of said existing room and a back edge of said shower base contacting a second existing wall of said existing room which is perpendicular to said first existing wall, said shower base being molded of a single piece of non-porous material to form a flat bottom surface for resting on said room floor, said shower base having a drain hole therein for allowing drain water from said shower to pass therethrough, a top surface of said shower base being molded to form a depression surrounding said drain hole for channeling water contacting said top surface at said depression into said drain hole, said top surface of said shower base being further molded to form a ramp at a ramp edge thereof which is opposite to said back edge, said ramp edge facing, but being spaced a substantial distance from, a third existing wall of said existing room which is perpendicular to said first existing room wall, said ramp leading upwardly from the bottom surface of said shower base at said ramp edge to a water-retaining barrier line on the top surface at a height of at least 1 inch above said bottom surface across the entire width of said shower base, said water retaining barrier line being positioned between said ramp edge and said depression and being space from said ramp edge not less than 3 inches, said depression beginning approximately at said barrier line;
• placing a modular wall against a second elongated side edge of said shower base, on an opposite side edge from said first existing room wall, on said floor, with a first end edge of the modular wall abutting against said second existing room wall, said modular wall having a length which is approximately the same as said shower base and a height which is substantially less than a height of said existing room extending from said floor to said ceiling and fastening said modular wall to said floor and said second existing room wall;
• mounting waterproof wall panels on said first existing room wall, said second existing room wall, and said modular wall so that bottom ends of said wall panels are sealingly attached to said shower base, whereby water flowing down said wall panels falls on said top surface of said shower base and cannot flow over said first, second, and back edges of said shower base;
• mounting a shower head and shower control knobs on said modular wall above said shower base;
• placing utility lines in said modular wall;
• mounting a planar vanity top on a non-shower side of said modular wall, edges of said vanity top forming a 90.degree. angle, with one of said edges being mounted on said modular wall and the other edge being mounted on said second existing wall to thereby support said modular wall to provide extra support between said modular wall and said second existing room wall, said vanity top including a sink and faucet with control knobs;
• connecting said shower head and faucet to said utility lines in said modular wall.
