Shower enclosure is coming along

Here we go finally the shower enclosure is up and braced. I just hope there is enough bracing ?  The underside of the shower pan was foamed into place for additional support. Now I just need to do some measurements so that the tile pattern will fit into place.

 This is the 4" pattern that I am thinking of.

Here is the finished and braced enclosure.

Metal bracing, front, back & everywhere.

Don't worry the exposed screws will be hidden latter.
