5.  Apply adhesive to the floor beneath the shower base. Apply enough adhesive to support the entire 
bottom of the shower base. This will add additional stability and prevent the base from shifting 
position. 
6.  We strongly recommend using a licensed plumber to connect the drain assembly to the 
drain pipe. If your selected drain is a glue-in style, apply the appropriate glue to the drain pipe 
and the inside surface of the lower drain body. Be sure to use the correct glue based on your drain 
pipe and drain assembly type (i.e. ABS or PVC). After the adhesive has been applied, place the 
shower base on the floor with the drain assembly sliding over the drain pipe. Push the shower base 
down until the top of the nailing flange aligns with the pencil marks drawn on the studs. Place a 
level on the threshold in all directions to ensure the base is completely level. Wipe away any excess 
adhesive.
