The dimensions for this Shower Tray is 59"x29-1/2"x3-3/38". I was unable to find one exactly 60"x30". Please let us know if there is anything else that we can help you with.
You may need a 790112000000000 tiling flange and the 790103000000000 tub anchors. The shower stopper is not included and any standard 4" grid strainer will fit this.
