Two piece molded fiberglass shower unit

A two-piece molded fiberglass shower unit comprising in combination:

• (a) a base section, said base section including a floor surface, a drain hole extending through the floor surface, a wall surrounding and continuous with said floor surface, a continuous top surface of said wall, and a continuous sealing ridge extending vertically from said top surface, said sealing ridge extending along a substantial portion of said top surface and leaving a gap corresponding to an entryway of said shower unit;
• and
• (b) a unitary wall section for attachment to said base section, said unitary wall section bounding a volume and having a side opening corresonding to and partially bounding the entry way of said shower unit, said unitary wall section including a continuous bottom flange, said bottom flange having therein a continuous ridge receiving slot for receiving said sealing ridge, said sealing ridge closely fitting in said ridge receiving slot for providing a sealed junction between said base section and said unitary wall section and for rigidly attaching said base section to said unitary wall section, whereby said base section can be installed or positioned before attachment of said unitary wall section thereto,
• said base section including a single piece section composed of molded fiberglass;
• said base section being substantially rectangular, said base section having first, second, third and fourth sides, said sealing ridge extending along said first, second and third sides, said unitary wall section having first, second and third wall panels, said ridge receiving groove extending coextensively with said sealing ridge along said first, second and third wall panels of said wall section;
• said unitary wall section including first and second flanges extending forward from said first and second wall panels, respectively, for effecting attachment of said unitary wall section to walls of a bounded shower unit installation region within which said shower unit is to be installed, said first and second flanges being flush with an outer surface of said first and second sides of said base section, whereby said flanges can be used as strips for nailing to the walls of the bounded shower unit installation region or for adhesive attachment thereto;
• said unitary wall section including first, second and third horizontal reinforcing members attached to said first, second and third wall panels, respectively;
• said wall of said base section having a vertical, upper, inner wall surface, said unitary wall section having a vertical lower, inner wall surface, said vertical, upper, inner wall surface being flush with said vertical, lower, inner wall surface when said base section is joined to said unitary wall section such that said sealing ridge extends entirely into said ridge receiving slot;
• said wall of said base section having a vertical, upper, outer wall surface, said unitary wall section having a vertical, lower, outer wall surface, said vertical, upper, outer wall surface being flush with said vertical, lower, outer wall surface when said base section is joined to said unitary wall sections such that said sealing ridge extends entirely into said ridge-receiving slots;
• said unitary wall section including first and second vertical posts bounding the entryway of said two-piece molded fiberglass shower unit, said first and second vertical posts being integral with said unitary wall section, there being no vertical joints between said first and second vertical posts and other portions of said unitary wall section,
• whereby said two-piece molded fiberglass shower unit avoids build-up of residue or mildew of the type that occurs in crevices, joints or seams that retain moisture in multi-piece shower units.
