These are all good and worthwhile ideas, thanks very much for adding them here!

Some of them would have been incorporated had I been starting completely from scratch. Some are definitely a case of "20-20 hindsight," and that's why publishing articles like this, and getting great comments like yours is a worthwhile effort... Particularly for the sake of the readers, and for returning here prior to the next project for recollection/reference purposes.

BTW, since these photos were taken, we have retrofitted a long, goose-neck shower head and a 1.5 gpm low-flow shower head. The gooseneck is one that holds its shape/position and can be aimed just about anywhere.

Thanks a lot for adding to the discussion! :)
