Looking at shower head. Nice dual rainfall design w/ walk-in. Need correctly sloped floor of course. With a walk-in, the towel rack can be placed by very close.
like the pocket doors- glass doors maybe a good idea from the great room to the 4 season porch to let the most light in. For even more light maybe fixed glass doors/windows on either side.
