Abstract

A method to install a shower floor includes the initial step of installing a drain conduit, after which a molded foam base is positioned over the drain conduit. A primary drain component is installed over the drain conduit and a spacer is secured to a flange on the primary drain component. Drainage openings are formed in the spacer. Flooring is laid on the foam base. Shims are applied to the spacer until the uppermost shim is flush with the flooring. A drain cover is mounted on the uppermost shim.

Claims

1. A method to install a shower floor comprising

(a) installing a drain conduit having an upwardly projecting cylindrical open end;

(b) providing a cylindrical primary drain component including

(i) a top with an outwardly extending flange,

(ii) a bottom,

(iii) an internally threaded inner cylindrical opening extending from said top to said bottom, said opening

shaped and dimensioned to receive said upwardly projecting end of said conduit such that said end is spaced apart from and concentric with said inner cylindrical opening, and

including a circular inwardly projecting seating flange, and

(iv) an externally threaded outer cylindrical surface extending from said top to said bottom;

(c) molding a polymer foam base with

(i) an upper surface,

(ii) a lower surface, and

(iii) an opening formed therein to fit over and receive said externally threaded outer cylindrical surface of said primary drain component;

(d) inserting said primary drain component in said opening in said polymer foam base;

(e) providing an internally threaded locking member;

(f) threading said locking member on said bottom of said primary drain component and against a portion of said polymer foam base to secure said primary drain component in said opening in said polymer foam base;

(g) installing said polymer foam base such that said open end of said drain conduit upwardly extends into said internally threaded inner cylindrical opening of said primary drain component;

(h) providing a hollow cylindrical pliable polymer sleeve shaped and dimensioned to fit intermediate

(i) said internally threaded inner cylindrical opening of said primary drain component, and

(ii) said drain conduit;

(i) installing said polymer sleeve intermediate said drain conduit and said internally threaded inner cylindrical opening;

(j) providing a hollow externally threaded compression member shaped and dimensioned to turn into said internally threaded inner cylindrical opening of said primary drain component;

(k) turning said compression member into said internally threaded inner cylindrical opening of said primary drain component to contact and compress said polymer sleeve between said drain conduit and said internally threaded inner cylindrical opening of said primary drain component;

(l) providing at least one hollow cylindrical spacer with at least one drain opening formed therein;

(m) securing said spacer to said flange of said primary drain component;

(l) applying flooring to said upper surface of said base;

(n) providing at least one hollow cylindrical shim;

(o) securing said shim to said spacer to compensate for the thickness of said flooring;

(p) providing a perforated drain cover; and

,

(q) mounting said drain cover on said shim.
